I've been thinking: What is it that enables a bad idea suddenly to spread across millions of people? Here are some of the things I have in mind:
- In France the National Front is reported as leading all other parties in current opinion polls, having won barely 10 percent of the vote in the 2007 presidential election.
- In January's general election, nearly 40 percent of Greek voters supported Syriza, compared wtih fewer than 5 percent as recently as 2009.
- Since narrowly rejecting indendence in last year's referendum, Scotland's voters have rallied to the Scottish National Party, support for which is now reported at over than 40 percent compared with less than 20 percent at the last general election.
- Most spectacularly, more than 80 per cent of Russians are regularly reported as thinking Vladimir Putin is doing a great job as their president, compared with around 60 percent two years ago.
I am hardly the first to ask this question. There is plenty of research (e.g. de Bromhead et al. 2013) on the economic conditions that foster political extremism, for example. But how do we get from economic conditions to wrong persuasion, exactly? There is the famous Goebbels quote about the "big lie," which is fine as far as it goes but always makes me think: surely there's more to it than this?
If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.
But it can't be true of all lies. Don't some lies work better than others? What is it that defines the ones that work? My best answer so far to this question is an analogy, which I know is less than proof. But it's a thought-provoking analogy; see what you think.
Last year some behavioural scientists (Strõmbom et al. 2014) finally explained how to herd sheep. There is a sheepdog, instructed by a shepherd, that does the running around. It turns out that there are just two stages. First, the dog must gather the sheep in a single compact group. Once that is done, the second step is to threaten the group from one side; as a group, the sheep will move away from the threat in the opposite direction. That's all there is to it.
The reason why the first step must come first is also of interest: If the dog threatens the sheep without first gathering them in a group, they will scatter in all directions, and that's not what the shepherd wants.
Anyway, there's the answer: Group, then threaten.
People are not sheep, and this is only an analogy. Nonetheless you probably already worked out how I would read this. The shepherds are the political leaders. The dogs that run around for them are the campaign managers and activists. The human equivalent of gathering sheep in a group is to polarize people around an identity that defines an in-group and an out-group. So Scots (as opposed to the English), Greeks (as opposed to the Germans), Russian speakers (as opposed to the rest). Group them, then threaten them, and they will move.
To see how the threat sets the group in motion we need one more thing, an insight from Ed Glaeser. Glaeser (2005) wanted to explain the conditions under which politicians become merchants of hate. He began with a community that has suffered some kind of collective setback. When that happens, people demand an explanation: Who has done this to us? "Us" means the in-group. Political entrepreneurs, he argued, will compete to supply satisfying stories. Often the most satisfying account is one that blames the in-group's misfortune on the alleged past crimes of some out-group: the English, the bankers, the Muslims, the Jews, or the West.
Not only past crimes, however; Glaeser uses the phrase "past and future crimes." In other words, he maintains, politicians often transform these stories into powerful threats by giving them a predictive slant: This is what they, the enemy, have done to us in the past and this is what they will do again if we don't mobilize to stop them first.
Remember: Group, then threaten. The result is mobilization.

On 27 January I was asked to join a panel on Russia's Future within the University of Warwick One World Week. (The other panel members were Richard Connolly, co-director of the University of Birmingham Centre for Russian, European, and Eurasian Studies, and the journalist Oliver Bullough.) I decided to talk about how Russians are looking to the past in order to understand their uncertain future. Here, roughly, is what I said:
Russia has many possible futures; all of them are improbable. The economy must do better, stay the same, or do worse. Relations with the West must improve, remain as they are, or deteriorate further. Adding them up, there are nine possible combinations. The probability of any particular combination is small, so each is improbable. But one of them must happen because, taken together, the sum of the probabilities is one. One of them must happen, but we have no idea which one.
Faced with an uncertain future, we often look to the past for guidance and reassurance. What was the outcome when we were previously in a situation that felt the same? At New Year, many Russians were looking to the past. I found this out when I stumbled on the website of RBC-TV, a Russian business television channel. Every day the RBC website polls its fans on a different multiple-choice question. On 30 December, the question of the day, with answers (and votes in parentheses), was:
What should Father Frost bring for Russia?
- End of sanctions (6%)
- End of the war in Ukraine (27%)
- A stable ruble (7%)
- Return of the Soviet Union (59%)
It's disconcerting to be reminded of the strength of nostalgia among Russians for the time when their country was a global superpower. The Soviet Union united all the Russias -- if anyone's not sure what that means, that's Great Russia, Little Russia and New Russia (Ukraine), and White Russia (Belarus) -- with the countries of the Baltic, Transcaucasia, and Central Asia. The Soviet Union stood for strong centralized rule, with a powerful secret police and thermonuclear weapons. The nostalgia is shared by President Putin, who said (on 25 April 2005): “The collapse of the USSR was the greatest geopolitical disaster of the [twentieth] century.”
Here's a question that RBC asked its supporters on 25 December:
Can direct controls and a price freeze save Russia’s economy?
- Yes, the free market is not up to the job (55%)
- No, that would cause insecurity and panic (40%)
- No need – no crisis (5%)
Again, the strength of support for the backward-looking answer is disconcerting. I tried to think of the last time the Russian economy was in a squeeze like today's. The last time the oil price price came down like this was the mid-1980s when North Sea and Alaskan oil broke the power of the OPEC cartel for a few years (that's the analysis of Anatole Kaletsky). The disappearance of oil rents probably contributed to the collapse of the Soviet economy.
But a closer parallel to today is 1930, when two things happened at once. The global market for Soviet exports shrank in the Great Depression. And international lending dried up, meaning that the Soviet economy could not roll over its debts. The Soviet import capacity collapsed almost overnight. Stalin responded by forcing the pace of import substitution through rapid industrialization. He demanded "The five plan in four years!" The result was a crisis of excessive mobilization that claimed millions of lives in the famine of 1932 and 1933.
Prominent in calling for an economic breakthrough today is President Putin, who responded to Western sanctions on 18 September 2014: “In the next 18 to 24 months we need to make a real breakthrough in making the Russian real sector more competitive, something that in the past would have taken us years.” Government-friendly Russian economists are talking about the need to go from a market economy back to a mobilization economy. In case the foreigners aren't getting the message, first deputy prime minister Shuvalov told those assembled in Davos on 23 January: “We will survive any hardship in the country – eat less food, use less electricity.”
A third question that RBC asked its viewers was on 19 December:
What matters most for the country right now?
- The foreign exchange rate (33%)
- Who is a true patriot and who is fifth column (56%)
- “Vyatskii kvas” (11%)
(The English equivalent of "Vyatskii kvas" would probably be Devon cider. For the reasons why it was being talked up as a solution to Russia's problems last December, click here.)
Here the strength of support for the backward looking answer is shocking. What is the "fifth column" and how does it resonate in Russian history? In 1937, Stalin saw Moscow surrounded and penetrated by enemies. This coincided with the siege of Madrid in Spain’s Civil War. In 1936 the nationalist General Mola was asked which of his four columns would take Madrid. He replied, famously: “My fifth column” (of undercover nationalist agents already in the city). In Madrid the Republicans responded by executing 4,000 nationalist sympathisers. In the Soviet Union Stalin, who was also watching, ordered the execution of 700,000 “enemies of the people.”
In recent times, the spectre of a "fifth column" was first reawakened by President Putin on 18 March 2014, when he remarked: "Western politicians are already threatening us with not just sanctions but also the prospect of increasingly serious problems on the domestic front. I would like to know what it is they have in mind exactly: action by a fifth column, this disparate bunch of ‘national traitors’, or are they hoping to put us in a worsening social and economic situation so as to provoke public discontent?"
Putin took up this theme again on 18 December 2014: "The line that separates opposition activists from the fifth column is hard to see from the outside. What’s the difference? Opposition activists may be very harsh in their criticism, but at the end of the day they are defending the interests of the motherland. And the fifth column is those who serve the interests of other countries, and who are only tools for others’ political goals."
Here you can see that Putin did affirm the possibility that opposition can be loyal. But is it possible for Russia to have a loyal opposition today? The only example of loyal opposition that Putin could bring himself to mention was the poet Lermontov -- who died in 1841.
These echoes of the Soviet past in Russian opinion today are disconcerting and even frightening. At the same time it is important to remember that, even while Russians look to the past, Russia today is absolutely not the Soviet Union. From today's vantage point it is nearly impossible to imagine how closed, stifling, claustrophobic, and isolated was everyday life even in late Soviet times. Russians in 2015 lead very different lives from Soviet citizens in 1985. They are richer, live longer, are able to visit, study, phone, and write abroad. Even today they are relatively free to search for and find information and discuss it among themselves. In all these ways, the transition from communism has not been a failure.
As Andrei Shleifer and Daniel Treisman (2014) wrote recently: "Putin’s authoritarian turn clearly makes Russia more dangerous. But it does not, thus far, make the country politically abnormal. In fact, on a plot of different states’ Polity [i.e. democracy] scores against their incomes, Russia still deviates only slightly from the overall pattern. For a country with Russia’s national income, the predicted Polity score [a measure of democracy] in 2013 was 76 on the 100-point scale. Russia’s actual score was 70, on a par with Sri Lanka and Venezuela."
To see Russia as just another middle income country helps us to identify Russia's underlying problem. In Russia, just like in Sri Lanka, Venezuela, and most countries outside “the West,” wealth and power are fused in a small, closed elite, and that is how it has always been. The fusion of wealth and power was and remains normal. Before the revolution Russia was governed by a landowning Tsar, aristocracy, and church. After the revolution Russia was governed by a communist elite that monopolized all productive property plus media, science, and education. Today Russia is governed by an ex-communist, ex-KGB elite that has once again gathered control of energy resources and the media. This fusion of wealth and power is neither new nor is it unusual among middle and low income countries.
In societies where wealth and power are fused, particular people are powerful because they control wealth and the same people are wealthy if and only if they are powerful. This is what gives politics in such societies its life-and-death immediacy. To lose power means to lose everything; when power change hands there is often violence. “All politics is real politics," write Douglas North, John Wallis, and Barry Weingast (2009); "people risk death when they make political mistakes.”
Several times in history, liberal reformers have tried to separate wealth and power in Russia and make space for public opinion. Here are some examples from the last 150 years:
- In 1864 a reform brought elected local governments – but within an absolute monarchy.
- Shaken by military defeats and popular insurrections, in 1906 the Russian monarchy introduced an elected parliament, although with few powers, and ndividual peasant landownership, although (as it turned out) with little time for implementation.
- In 1992 and 1995 Russia saw voucher privatization and "loans-for-shares," creating a class of corporate shareholders – but the outcome was crony capitalism, not free enterprise.
- In 2003, Mikhail Khodorkovskii tried to separate the governance of Yukos from the "power vertical," but he went to prison for it.
All these efforts have so far achieved only partial or temporary success. Russia has not yet found a solution to the problem of the fusion of wealth and power. Here, at last, is an aspect of Russia's future that is certain: If Russia is ever to find a solution to this problem, it will be there.

Today sees a new version of the Dexter-Rodionov guide to The Factories, Research and Design Establishments of the Soviet Defence Industry. This is the sixteenth edition; the very first (in which I was co-author) appeared in January 1999. In that time the datset has grown from just over 2,000 entries to nearly 30,000, and the detail from around 100kb to more than 10Mb.
From the start this was a curiosity-driven project. The Soviet military-industrial complex was veiled in secrecy for decades. In 1992 the former Soviet archives were opened up for independent research. Google's Ngram viewer lets you see how the subject broke out into the light of day. The chart shows the relative frequency of the phrase "советский военно-промышленный комплекс" (Soviet military-industrial complex) in Russian-language publications from 1917 to 2010. A few of these would have occurred in items published in Russian outside the Soviet Union; I suspect that explains the first observations from the 1970s and early 1980s.
What were the factories that made Soviet weapons and military equipment? How many and how important were they? Where were they? When were they built? How specialized were they, and how self-sufficient? We just wanted to know.
My co-author of the time, Nikolai Simonov, was showing me some of the lists of secret ("numbered") defence factories in the 1920s and 1930s that he had found in the archives. I knew that Julian Cooper at Birmingham had his own files. We were soon joined by Keith Dexter, an authority on Soviet aviation. We put together what we had and the result was the first edition of the present guide. If you are at all interested in the history of exactly how and when the Soviet defence industry was made secret, I still recommend that you read Julian Cooper's introduction to this first edition.
Soon after that, Keith drew in Ivan Rodionov, another aviation expert, and so it became the Dexter-Rodionov guide.
What's new in version 16, apart from additional detail? The cover page carries the chart below, which shows the growing number of Soviet enterprises engaged in defence production from 1917 through 1991, distributed among the major production branches.
Here are my takeaways (thanks to Dexter and Rodionov for drawing my attention to some of these):
- The breakneck pace of Stalin's rearmament from the mid-1930s is clearly visible. It culminated in the war, and the first spike which is recorded in 1944).
- Also visible is the more moderate but sustained growth of defence plants after the war, including the rapid surpassing of the wartime peak.
- There is a second spike in the number of defence plants in 1964. This was the year in which Khrushchev was outmanoeuvred and replaced by Brezhnev. It suggests an economic issue in the power struggle: was Khrushchev trying to build up defence production at a pace that others considered to be infeasible?
- The changing composition of the defence sector has two striking aspects. One is the vast growth of radioelectronic establishments. By the end, this sector alone accounted for half of the entire Soviet defence industry.
- The other aspect is the tremendous stability of the traditional sectors: armament, armour, and shipbuilding. It would not come as any surprise to a student of the Soviet economy to learn that they could create new sectors (like the nuclear industry or radioelectronics) but even if they wanted they couldn't close the old ones down.
Finally, the chart shows us that by the end there were just over 5,000 plants engaged in defence production. How many is that? In 1987 (according to the Soviet statistical handbook of that year) there were more than half a million state-owned establishments of all kinds in the Soviet economy. So, we are looking at no more than one per cent of the total, and one per cent does not seem like a lot. The explanation is that most defence plants were relatively large. Their share in the whole economy, measured by capital assets or production, was many times greater than their share in the number of plants.
As for the share of defence production in the whole Soviet economy, we are still a long way from being able to pin that down. For any other country the most obvious way to do it would be to work from the expenditure side, by comparing the size of the Soviet military budget with the size of the economy, as opposed to working from the production side, which raises a lot of complicated issues about plant specialization and intermediate production. Alas, in the Soviet case it is no less of a problem to work from the expenditure side, because Soviet defence expenditures were also highly secret. Here I mean true military expenditures, not the officially published figures which were as phoney as a three-dollar bill. In fact, the real figures were so secret that by the end nobody knew what they were! And i mean nobody, literally; I wrote about it here.
The Soviet military-industrial complex continues to throw up many challenges for historical research. The Dexter-Rodionov guide is a terrific place to start looking for both questions and answers.

Torture is wrong. Applied to interrogation it is unproductive. Given these two things, it should be easy for interrogators to choose not to use torture. Despite this, torture is widely and persistently used in interrogation around the world. So here, apparently, is a puzzle. Why does torture persist? The solution to the puzzle is found in a third feature: torture is corrupting.
Today's publication of the US Senate Select Committee on Intelligence report on the Central Intelligence Agency 's Detention and Interrogation Program will be noted mainly for its detailing of the fates of the 39 CIA detainees who were subject to "enhanced interrogation" (or torture).
Also notable, however, is the report's documentation of the CIA's determined defence of its practices, extending to concealment and misrepresentation of the facts in order to evade accountability. This defence began concurrently with "enhanced interrogation" but it is not confined to the past. It continues today and will no doubt be maintained tomorrow.
It was 9/11 that moved me to write regularly on public affairs. I didn't have a blog, so I just wrote short papers and uploaded them to a web page. In November 2001 torture was already being floated in public as a way to get US detainees to talk about terrorist conspiracies. It seemed to me that European history already provided ample evidence that this was a bad idea, so I wrote a short paper to explain why.
My last-but-one paragraph from that paper is relevant to the idea that torture cannot be a temporary expedient. Even if it turns out to be a bad idea, once you start, it's hard to stop. It also helps to explain why a body like the CIA would become committed to a bad idea and continue to defend it to the present. What I wrote thirteen years ago seems as good today as I thought then, so I'll quote that last-but-one paragraph in full.
A final and most important consequence is that the process of torture is corrupting. Torture creates employment for the interrogators, and privileges that stem from the capacity to instill fear. The practice of torture also attracts those who find it enjoyable and use it as an instrument of self–gratification rather than investigation. Thus it gives rise to vested interests in its continuation that do not wish to be held accountable for their actions. These interests are helped by secrecy. Torture takes place in secret. Most people find the subject distasteful and do not wish to know about it, and this further strengthens the wall of secrecy. The result is a part of the state that exercises a cruel and tyrannical power over society, one that grows inevitably with the extension of torture and has the power to resist subsequent attempts to curb it.

Recently Warwick’s History Department held a roundtable on Thomas Piketty’s important and bestselling blockbuster, Capital in the Twenty-first Century (Piketty 2014). I was on the panel, which was ably organized and chaired by Maxine Berg, whom I thank for the invitation. Here I’ll summarize my remarks, which have benefited from listening to the other panelists and the discussion. For better or worse my words seem to have been modified by the passage of time; I sense that their tone has sharpened since that evening.
Piketty’s book has been reviewed thousands of times; we have already seen reviews of the reviews. I have little to say that can be original. I prefer not to comment on Piketty’s conclusions, because most readers seem to have made up their minds on those before reading the book. Instead, I’ll focus on the early chapters, where Piketty sets out his contention that “capital is back”; nearly everything else in the book follows from that foundational claim.
Here’s the short version of my assessment: The problem? Hugely topical. I won’t spend any time on that. The model?Unobjectionable in principle, flaky in use. I’ll explain briefly. The historical data? A wonderful contribution, yet they do not show what many suppose, and that would seem to include Piketty himself. My conclusion? Capital is back -- but not as corporate capital. If capital is back, it is not, apparently, because of financial deregulation or capital account liberalization. And, if capital is back, there are clear candidates for countervailing forces that will tend to restrict its further rise in the twenty-first century.
Now for the detail, some of it unavoidably technical. Let’s start with the model. Piketty writes (2014, p. 32):
The discipline of economics has yet to get over its childish passion for mathematics and for purely theoretical and highly ideological speculation …
(So of course we don’t expect to find anything like that in the pages that follow.) What we do find is this:
- A first fundamental law (p. 52): the profit share in income rises with the profit rate on capital and with the capital/income ratio.
α = rβ
- A second fundamental law (p. 166): the capital/income ratio rises with the saving rate out of income (which governs the rate at which income adds to capital), and it also rises as the income growth rate falls.
β → s/g
- A fundamental force (p. 35): profit rate on capital tends to exceed income growth rate.
r > g
The generality of the model is notable. In fact there is almost nothing in it, so far, that could be considered novel. It is also simple to an extreme. Of course, all models are just simplified representations of reality. Is it oversimplified? The question calls to mind the maxim of Box and Draper (1987, p. 74):
All models are wrong; the practical question is how wrong do they have to be to not be useful.
Our question for Piketty, correctly formulated, is not whether his model is “wrong,” as it surely is, but whether his model is “not-wrong” enough to be useful. Considered in these terms, the maths is not the problem. The problem is in the application of the maths to a necessarily complex reality.
How does this simple model lend support to the claim that capital is back? Piketty puts his two laws and the fundamental force to work in the following way.
- Start with the fundamental force: r > g. Here is a gap, made up by the excess of the rate of return on capital over the growth rate of the economy. According to Piketty the gap has widened because g has fallen (pp. 99-102), but r is fairly stable and we do not expect it to fall (pp. 220-223).
- Now the second law comes into play: β → s/g. Piketty appears to argue that the saving rate is stable, or at least is not falling (pp. 173-178), but the growth rate has fallen, so β, the ratio of capital to income, must be rising towards a new, higher steady state.
- Finally the first law swings into action: α = rβ. Given that the capital/income ratio is rising and the rate of return on capital is not falling, the profit share in income must be rising too, with all that might imply for social inequality.
- (The maths is neat too: the three expressions collapse easily into α → s × r/g, meaning that the steady-state profit share equals the saving rate times the rate of return over the growth rate. So far, the logic is unassailable.)
The question that comes naturally to mind is whether Piketty might have neglected some countervailing force that would eventually nullify or attenuate the tendency that he has identified. (In thinking about this I’ve been influenced by the insights of many, but I ought to mention especially Krusell and Smith 2014).
Picketty concludes that capital is back because, he maintains, the growth rate of the economy has fallen, the rate of return on capital is relatively stable, and so is the saving rate out of income. How robust is this chain? Consider each link in turn.
- First, Piketty asserts that the long-term growth rate of the economy has fallen: Maybe, but also maybe not. Secular stagnation is possible but the concept is also speculative and contentious (for discussion see Teulings and Baldwin 2014). It is even a little unhistorical – the last time secular stagnation was predicted was at the end of the 1930s, since when global output has multiplied by at least 10 times (Maddison 2010). If the prediction of secular stagnation turns out wrong, then Piketty’s prediction is largely sunk by a countervailing factor: the return to faster growth will hold down the capital/income ratio and the profit share in income.
- Second, Piketty asserts that the rate of return on capital will not decline as capital is accumulated. This outcome is possible, of course, in the general sense that we really don’t know about the future of technology, but this one too is speculative and contentious. A long term conjunction of low growth, high capital accumulation, and high profits is (in my opinion) highly improbable. If we are doomed to secular stagnation, and capital accumulation continues unchecked, the return on new investments will surely fall relative to the past. If the return on capital declines significantly as capital is accumulated faster than income, then here is a factor that would automatically hold down the profit share in income. Thus, a fall in the rate of return cannot be ruled out and would be another countervailing factor.
- Third, Piketty appears to rely on maintenance of the saving rate out of income. Others have noted that Piketty should have distinguished between gross and net saving. Here net saving = gross saving – depreciation, and depreciation means the annual deterioration of the capital stock through wear and tear and obsolescence. Piketty gets the definition, of course (p. 178), but on my reading he misapplies it. The point is that depreciation is a function of the capital stock: the more capital we hold, the greater must be our provision for its depreciation. Depreciation is not a function of income. If the capital/income ratio rises, then the depreciation/income ratio must rise too. Piketty doesn’t appear to get this (p. 178 again), because he presents depreciation as a proportion of income, not of capital. If the capital/income ratio rises, the depreciation/income ratio must rise. If the depreciation/income ratio rises, and if gross saving is stable, then net saving out of income must fall. If the result of capital accumulation is a fall in the net saving rate, then this must slow net capital accumulation, making a third countervailing factor.
The three countervailing factors are reasons why I concluded that Piketty's basic insight is flaky, in the sense that it might be a good description of what is going on but equally it might not. Still, this does not settle the bigger question: do its predictions fit the known facts? If so, it must surely still merit serious consideration; perhaps the countervailing factors are simply unimportant?
The test here is: what’s been happening to the capital/income ratio? And Piketty’s data do show that the capital/income ratio is rising, don't they? Well, let’s check the data (and here I need to acknowledge a debt to Bonnet, Bono, Chapelle, and Wasmer 2014).
Piketty has five countries in his sample: Britain, France, Germany, Canada, and the US. These data show, as is now well known, a U-shaped pattern in the ratio of capital to income over the twentieth century: high at the beginning, slumping in mid-century, and rising again: hence, “capital is back.”
Piketty’s explanation, by the way, is that in the era of the two world wars the asset markets of these five countries underwent a common pattern of regulation that depressed relative asset prices, and neoliberal deregulation has now released them.
But there are strange things in the data. They are not immediately apparent from Piketty’s stacked-area charts, mostly because of the vertical ordering of the series. (To a smaller extent they are affected because Piketty does not understand how Excel processes the data for stacked charts when one of the series has negative values, as is the case for net foreign capital order in several countries, although only Canada is seriously affected.)
- First strange thing: If we accept that capital is back, it is not all elements of capital that are back, and it is specifically not corporate capital. It is residential capital. Residential capital is certainly part of the capital stock, but it is probably not what most people think of when they think about the return of (or on) “capital.” More likely they think about Goldman Sachs or Amazon. But capital is not back because of Goldman Sachs or Amazon.
A simple calculation makes the point. For each country, take the increase in the capital/income ratio from 1950 to 2010. Then calculate how much of that increase is due to rising values of residential capital. The result is the proportion of the increase in capital/income from 1950 to 2010 that is explained by the increase in housing wealth:
- United Kingdom 72%
- France 103%
- Germany 102%
- Canada 63%
- United States 72%
The figures show that in every country housing wealth accounts for at least three fifths of the increase in the capital/income ratio since the middle of the twentieth century, and in two countries (France and Germany) it accounts for all of the increase in the ratio.
- Second strange thing. If housing wealth is so important to the claim that “capital is back,” what can we say about the return on housing wealth? Go back to the basic model to recall that the stability of the return on capital is crucial to Piketty’s prediction that the capital share of income is rising. Is the return on housing capital stable? No, it’s not. Bonnet et al. (2014) show clearly that in four out of five countries the return on housing wealth, measured by the ratio of housing rents to housing prices, has fallen over forty years from 1970 to 2010: in the US by nearly 20 percent, and in Britain, France, and Canada by around 40 percent. Only in Germany has it risen.
- Third strange thing: Asset prices are formed in markets. Sometimes, these markets are regulated, and this affects prices. There are variations across markets and across countries in how regulated these markets are, and I am not expert in measuring this variation. But I venture to claim that in every wealthy country the housing market is one of the most regulated asset markets. Indeed bad regulation of the US housing market was arguably a prime cause of the asset price crash and financial crisis of 2008 (Rajan 2010). And if housing wealth is increasingly a factor in inequality in the UK, policy interventions that have pumped up the demand and restricted the supply must shoulder much of the blame.
To conclude: Capital is back -- but not as corporate capital. If capital is back, it is not, apparently, because of financial deregulation or capital account liberalization. And, if capital is back, there are clear candidates for countervailing forces that will tend to restrict its further rise in the twenty-first century.
if I had been Piketty’s editor I would have been excited and honoured to publish his book. But I might not have allowed him to call it Capital in the Twenty-first Century. More accurately, it would have been called Housing in the Twenty-first Century. But then there would be a marketing problem, because Marx never wrote three volumes on Die Behausung, and Piketty's publisher would have lost a lot of sales. Well, that’s business.

The Conversation published this column on the seventieth anniversary of D-Day, June 6 2014. I thought I'd include it here.
On June 6, 1944, more than 150,000 Allied troops landed in Normandy. Their number rose to 1.5m over the next six weeks. With them came millions of tons of equipment, ranging from munitions, vehicles, food, and fuel to prefabricated floating harbours.
The achievement of the Normandy landings was, first of all, military. The military conditions included co-operation (between the British, Americans, and Free French), deception and surprise (the Germans knew an invasion was coming but were led to expect it elsewhere), and the initiative and bravery of officers and men landing on the beaches, sometimes under heavy fire. More than 4,000 men died on the first day.
D-Day was made possible by its global context. Germany was already being defeated by the Soviet Army on the eastern front. There, 90% of German ground forces were tied down in a protracted losing struggle (after D-Day this figure fell to two-thirds). The scale of fighting, killing, and dying on the eastern front was a multiple of that in the West. For the Red Army in World War II, 4,000 dead was a quieter-than-average day.
Economic factors were also involved. In 1944 the main fighting still lay in the east, but the Allied economic advantage lay in the west. Before the war the future Allies had twice the population and more than twice the real GDP of the Axis powers. During the war the Allies pooled their resources so as to maximise the production of fighting power in a way that the Axis powers did not attempt to match. America made the biggest single contribution, shared with the Allies through Lend-Lease.
Between 1942 and 1944 Allied war production exceeded that of the Axis in every category and on all fronts. This advantage was especially great in the West. In the chart below, a value of one on the horizontal plane would mean equality between the two sides. Values above one measure the Allied dominance:
Eventually the accumulation of firepower helped turn the tide. A German soldier in Normandy told his American captors, “I know how you defeated us. You piled up the supplies and then let them fall on us.”
D-Day was made possible by economics, but it was made inevitable by other calculations. When the outcome of the war was in doubt, Stalin demanded the Western Allies open a “second front” in Western Europe to take pressure off the Red Army. At this time, working towards D-Day was a price that the Allies paid for Stalin’s cooperation in the war. By 1944 German defeat was assured; now D-Day became a price the Western Allies paid in order to help decide the post-war settlement of Europe.
While D-Day was inevitable, its success was not predetermined by economics or anything else. The landings were preceded by years of building up men and combat stocks in the south of England, and by months of detailed logistical planning. But most of the plans were thrown to the wind on the first day as the chaos of seasick men struggling through the surf and enemy fire onto the Normandy sands unfolded. This greatest amphibious assault in history was a huge gamble that could easily have ended in disaster.
Had the D-Day landings failed, our history would have been very different. The war would have dragged on beyond 1945 in both Europe and the Pacific. Germany would still have been undefeated when the first atomic bombs were produced; their first victims would have been German, not Japanese. Germany and Berlin would never have been divided, because the Red Army would have occupied the whole country. The Cold War would have begun with the Western democracies greatly disadvantaged. We have good reason to be grateful to those who averted this alternative history.

In an old English story, a tramp was asleep in the grass by a lane. The landowner woke him roughly:
Get off my land!
The tramp replied:
How come it's your land?
My ancestors fought for it!
Then I'll fight you for it.
This story offers a dubious principle and an excellent moral. The dubious principle is that property is theft: no one's claim on property is more legitimate than anyone else's. The excellent moral is that if we lived by that principle our's would be a world of chronic insecurity and unremitting threats in which no one could sleep peacefully.
In that light, here are some facts about Russia.
- Russia's territory covers more of the globe than any other country: more than 17 million square kilometres.
- Russia's land border is the second longest in the world: more than 20,000 kilometres, shared with 16 sovereign neighbours.
- Between 1870 and 2001, the Correlates of War dataset on Militarized Interstate Disputes counts 3,168 bilateral conflicts involving the show or use of force. Every dispute involves a country pair, and the same dataset also registers the country that originated the dispute. Over thirteen decades Russia (the USSR from 1917 to 1991) originated 219 disputes, more than any other country. Note, by the way, that this is not about capitalism and communism; Russia's pole position is the same both before and after the Revolution. Also-rans include the United States (in second place with 161 conflicts) China (third with 151), the UK (fourth with 119), and Iran (fifth with 112). (My more patriotic readers will want to know where Germany stands: lagging behind at sixth with 102). These results are reported by Harrison and Wolf (2012, p. 1064, footnote 29).
Why has Russia achieved this preeminent position in the history of conflict? Here are three reasons.
- Russia is large, and small countries have little weight to throw around.
- Russia has many neighbours, and therefore many opportunities to engage in bilateral disputes.
- Russia's regime has always been authoritarian, with the exception of the few years either side of the collapse of communism, when Russia's borders were able to change relatively peacefully. It is an established empirical regularity that authoritarianism predisposes a state to engage in conflict (the literature is surveyed and also qualified by Harrison and Wolf).
In most of European history, borders have changed through violence. The Eurasian landmass is for the most part a vast plain, with mountains only on the margins, and without natural frontiers. The absence of natural defences other than a few rivers and wetlands has allowed armies to roam freely back and forth across vast distances, killing as they go. European sovereignty was based on possession, and sovereignty changed hands when rivals fought for it.
The stability of borders is a tremendously important condition for economic development. Unstable borders engender conflict, raiding, and killing. Stable borders can be opened for trade and the movement of merchandise and merchants. The goods, cultural values, skills, and talents that flow across stable borders enrich both sides. Stable borders also allow the development of democracy, as argued by Douglas M. Gibler (2007), whereas territorial disputes prevent it.
Russia has suffered terribly from the territorial disputes of past centuries. When the Soviet Union broke up, Russia's new borders were drawn for the most part peacefully. This was a tremendously hopeful omen for Russia's future. Particularly important were the assurances given to Ukraine in 1994: Ukraine gave up its nuclear weapons and in return the US, UK, and Russia guaranteed Ukraine's territorial integrity. It is all the more shocking that Russia has created an opportunity, which it is now seizing, to revise its border with Ukraine unilaterally and by force.
That some Russian nationalists now regret the 1994 agreement is completely irrelevant: Russia gave its word, and so did we.
In the present crisis the issue that should take precedence over all others is the integrity of European borders and the process of adjusting them lawfully and without violence. That should come before everything else, including rights of self-determination and the political composition of this or that government. No good will come of Russia's violation. We all stand to lose by it. But anyone with knowledge of Russia's history knows that Russia, of all countries, has most to lose by returning Europe to the poisoned era of conflicted borders and perpetual insecurity.

An old joke has resurfaced in connection with Ukraine's Crimean crisis. I saw it first in a column by my co-author Paul Gregory:
You want to live in France? Go to France. You want to live in Britain? Go to Britain. You want to live in Russia? Stay where you are: Russia will come to you.
It's generally hard to work out when and where such jokes originated, but this one has real-life foundation.
Before the war Menachem Begin, who was later Israel's prime minister, was a Jewish activist in Poland. When Germany and the Soviet Union divided Poland in 1939 he fled to Lithuania, where Soviet troops arrived in 1940. With thousands of others, Begin was arrested. He was accused of being a British agent under Article 58 of the RSFSR (Russian republic) criminal code, which dealt with counter-revolutionary crimes. In a later memoir Begin recalled a prison conversation (Weiner and Rahi-Tamm 2012, p. 14):
When Begin inquired how article 58 of the Soviet Criminal Code (counter revolutionary activity, treason, and diversion) could be applied to activities that were considered legal in then sovereign Poland, his interrogator did not hesitate: “Ah, you are a strange fellow [chudak], Menachem Wolfovich. Article 58 applies to everyone in the world. Do you hear? In the whole world. The only question is when he will get to us or we to him.”
This raises an interesting question: If the jokes are the same, is the system the same? In other words, is Putin's Russia the same as Stalin's Soviet Union? In most aspects of everyday life the answer is: Clearly not. In Russia today there is far more freedom of speech, assocation, and enterprise than there ever was in the Soviet Union. But there is also much less of these things than there should be. And there are disturbing continuities with the Soviet past in Putin's KGB background and loyalty, his nostalgia for the Soviet empire, and the identification of national power with his personal regime.
Directly linked to these things is continuity in Russia's menacing approach to its neighbours. The people of what was once eastern Poland (now western Ukraine and western Belarus), and Lithuania, Latvia, and Estonia, are being reminded today that they live in territories to which "Russia came" in 1939 and 1940. These occupations were followed by unanimous parliamentary votes and rigged referenda, the registration of the population and issuing of "passports" (ID cards), and mass arrests and deportations.
If we are returning to the past, one may hope for a new era of Russian jokes. Unfortunately, it may turn out that the best jokes have already been told.

The athletes gathering in Sochi for the Winter Olympics must regret the fact that the threat of terrorism is commanding as much media atttention as the prospects for sporting excellence.
The extent of the terrorist threat to Sochi is a measure of how Russia has changed. The Soviet Union offered little scope for terrorism. Under intense state and party surveillance it was very difficult for non-state actors to spread a message or recruit. It was not obvious what would make an effective target for a terrorist act and the state was fully capable of suppressing any publicity that would normally follow in an open society. Terrorist acts were rare. Nonetheless, a few did take place.
While studying the records of the KGB of Soviet Lithuania (held on microfilm at the Hoover Institution), I came across documentation of such a case. On a Saturday afternoon in January 1977, three bombs were detonated in Moscow, one in a subway train, another in the street, and a third in a food store. The attack came out of the blue: there was no warning and no one claimed responsibility. Seven people were killed and 44 injured. Two days later, on January 10, the Soviet news agency TASS issued an uninformative bulletin that mentioned only the subway blast and concealed the deaths.
The KGB was completely at a loss where to look for the perpetrator, so they looked everywhere -- including Lithuania. The investigation took many months; almost a year passed before arrests were made. I'm not going to tell the story of the investigation here; I've published the main story elsewhere and you can also read a more detailed version in a working paper with footnotes.
The thing that interested me most was what I learned about the career concerns of KGB operatives. It worked like this.
- If you were Yurii Andropov, the USSR KGB chief in Moscow, you naturally had what Mancur Olson would have called an "encompassing interest" in identifying and catching the culprits as soon as possible.
- At the next level down, if you were Juozas Petkevičius, the Soviet Lithuania KGB chief in Vilnius, your concerns were more complicated. Your first priority was to ensure that the culprit was not in Lithuania. The culprit had to be somewhere, of course, and the chance that he (or she, but let's be realistic: most terrorists are male) was in Lithuania was very small (1 percent of the Soviet population). Moreover, if the perpetrator was found in Lithuania, Petkevičius could expect a career setback, because this would be someone the local KGB had overlooked or underestimated. One could understand it if Petkevičius had chosen to let sleeping dogs lie. But he couldn't, because then he would face an even worse career risk: that some other branch of the KGB would come into Lithuania and find the terrorist that the locals had overlooked. So Petkevičius did the right thing and mobilized his forces to scour Lithuania for the culprit, if the culprit was to be found there.
- There were still lower levels, headed by chiefs of KGB city and rural district administrations, and so on down to factory and ward officers, workplace and apartment block informers, and so forth. At each level the KGB staff and agents faced the same conflicting pull as Petkevičius, but the balance changed. By the time you came down to a village or street, the chance that the culprit had chosen to hide out exactly there, as opposed to any other street in the entire Soviet Union, was absolutely infinitesimal. Correspondingly, as you went down the hierarchy, the risk of slacking and the incentive to search weakened and dwindled to zero. The only remaining incentive to search was to please the boss. Therefore, as time went by, Petkevičius became more and more concerned that no one below him was trying hard. And he needed them to try hard, so he pleaded and threatened and bullied.
Why is this interesting? Because we might think of the KGB as a special, elite organization full of dedicated, self-motivated patriots and loyalists. Yet, when push came to shove, in the face of a national emergency, most employees behaved like the staff of any bureaucracy: they responded to career concerns, and not otherwise.
PS If you follow my links to the full story, you'll find that what happened in the end was exactly what Petkevičius must have feared most -- but it happened elsewhere, to another regional KGB boss who was found to have held the terrorist leader in his hands and let him go.

Writing about web page http://www.voxeu.org/article/costing-secrecy
Yesterday VOX published a short column that I wrote about Costing Secrecy. The teaser is as follows:
Democracy often seems bureaucratic with high ‘transaction costs’, while autocracies seem to get things done at lower cost. This column discusses historical research that refutes this. It finds empirical support from Soviet archives for a political security/usability tradeoff. Regimes that are secure from public scrutiny tend to be more costly to operate.
A starting point of my column was that communist rule in the Soviet Union gave rise to one of the most secretive systems of government that has ever been devised. I'm always looking out for ways to illustrate this, and I found a new way recently with the help of Google's Ngram Viewer(thanks to Jamie Harrison). The Ngram Viewer searches the Google Books corpus for words and word combinations and shows their changing frequency over time. The chart below shows the result of searching in the Russian corpus for the word "Главлит" (Glavlit).
Glavlit, the Soviet Union's Chief Administration for Affairs of Literature and Art, was created in 1922 to centralize the censorshop of the media. The background is that the Bolsheviks introduced censorship in November 1917 as one of the first acts of the Revolution (the "Decree on the Press"). During the Civil War that followed, they operated censorship through many agencies at many levels. Glavlit pulled it all together into a single, unified agency. The official title of Glavlit changed a few times over the next 70 years. Still, no one ever called it anything but "Glavlit," even in official government and party documents.
My current research is on secrecy. Censorship and secrecy are not the same. But they are closely connected. Enforcing government secrecy was one of the most important functions of censorship. In addition, Glavlit was a government agency, and its working arrangements were entirely secret, so the censorship had to censor the facts of its own operations.
How effective was Soviet censorship? The frequency with which the chief agency of censorship was mentioned in published works offers a simple measure in one dimension. Here it is:
Notes: My guess is that the Google Books Russian corpus must include books published in the Russian language abroad, out of reach of the Soviet censor, as well as within the Soviet Union. For transparency the chart is completely unsmoothed. In the years of the Civil War (1918 to 1920) and World War II (1941 to 1945) fewer books were published, making observations in those years more susceptible to the law of small numbers. You can view and play with the chart here in its home setting.
There is a simple message. The Soviet censorship agency was openly acknowledged and discussed at the time of its establishment and for a few years afterwards. From the mid-1920s it faded rapidly from sight. By 1931, when Stalin was fully in charge, its disappearance was almost total. For more than half a century Glavlit successfully covered its own tracks. Fifty-six years later, in 1987, Gorbachev launched his policy of "glasnost" (openness). Only then did Glavlit gradually come back into uncensored view. Glavlit was finally abolished in 1991.
In short: Soviet censorship worked.
