  • The Long Run Effects of Religious Persecution: Evidence from the Spanish Inquisition [with Mauricio Drelichman, Jordi Vidal-Robert], Proceedings of the National Academy of Sciences (PNAS) 118 (2021)

    Religious persecution is common in many countries around the globe. There is little evidence on its long-term effects. We collect new data from all across Spain, using information from over 67,000 trials held by the Spanish Inquisition between 1480 and 1820. This comprehensive new database allows us to demonstrate that municipalities of Spain with a history of stronger inquisitorial presence show lower economic performance, educational attainment, and trust today. The effects persist after controlling for historical indicators of religiosity and wealth, ruling out potential selection bias.

  • Killer Incentives: Status Competition and Pilot Performance during World War II [with Philipp Ager, Leo Bursztyn, and Lukas Leucht], forthcoming, Review of Economic Studies [VoxEU] [NBER Digest

    Using newly-collected data on death rates and aerial victories of more than 5,000 German fighter pilots during World War II, we examine the effects of public recognition on performance and risk-taking. When a particular pilot is honored publicly, both the victory rate and the death rate of his former peers increase. Fellow pilots react more if they come from the same region of Germany, or if they worked closely with him. Our results suggest that personal rivalry can be a prime motivating force, and that non-financial rewards can lead to a crowd-in of both effort and risk-taking via social connections.

  • Financial Crises and Political Radicalization: How Failing Banks Paved Hitler's Path to Power [with Sebastian Doerr, Stefan Gissler, Jose-Lluis Peydro], forthcoming, Journal of Finance [VoxEU] [ungated wp version]

    Do financial crises radicalize voters? We analyze a canonical case -- Germany during the Great Depression. After a severe banking crisis in 1931, caused by foreign shocks and political inaction, radical voting increased sharply in the following year. Democracy collapsed six months later. We collect new data on pre-crisis bank-firm connections and show that banking distress led to markedly more radical voting, both through economic and non-economic channels. Firms linked to two large banks that failed experienced a bank-driven fall in lending, which caused reductions in their wage bill and a fall in city-level incomes. This in turn increased Nazi Party support between 1930 and 1932/33, especially in cities with a history of anti-Semitism. While both failing banks had a large negative economic impact, only exposure to the bank led by a Jewish chairman strongly predicts Nazi voting. Local exposure to the banking crisis simultaneously led to a decline in Jewish-gentile marriages and is associated with more deportations and attacks on synagogues after 1933.

  • Highway to Hitler [with Nico Voigtländer], forthcoming, American Economic Journal: Applied [VoxEU]

    Can infrastructure investment win "hearts and minds"? We analyze a famous case in the early stages of dictatorship the building of the motorway network in Nazi Germany. The Autobahn was one of the most important projects of the Hitler government. It was intended to reduce unemployment, and was widely used for propaganda purposes. We examine its role in increasing support for the NS regime by analyzing new data on motorway construction and the 1934 plebiscite, which gave Hitler great powers as head of state. Our results suggest that road building was highly effective, reducing opposition to the nascent Nazi regime.

  • Persistence: Myth and Mystery, just published, Bisin and Federico, Handbook of Historical Economics [SSRN wp] [CEPR dp] 

    Is long-term economic persistence a myth? In this survey, I examine what has been learned from the wave of articles examining the persistence of economic phenomena. The article clarifies some of the concepts, distinguishes different strands of the literature, and questions the validity of recent critiques of persistence papers. While challenges in the form of misattribution and p-hacking abound, this survey concludes that persistence is real, and that future research should focus on mechanisms and the conditions under which persistence breaks down.

  • Collective Remembrance and Private Choice: German-Greek Conflict and Consumer Behavior in Times of Crisis [with Vicky Fouka], revise and resubmit, American Political Science Review  [VoxEU

    How is collective memory formed and when does it impact behavior? During World War II, German troops occupying Greece carried out numerous massacres, often as reprisals for partisan attacks. During the recent Greek sovereign debt crisis, political conflict erupted between the German and Greek governments; German car sales in Greece declined. Reductions were greatest in areas affected by German reprisals. Differential economic performance did not drive this divergence. Instead, survey evidence and an IV-strategy explaining the geography of German attacks suggest that current events reactivated past memories, creating a backlash against German products in reprisal areas. Using quasirandom variation in official public recognition of a towns victim status, we show that the institutionalization of collective memory amplifies effects of time-varying political conflict on consumer behavior.

  • Discretion and Destruction: Promotions,Performance, and Patronage in the Royal Navy [with Guo Xu], revise and resubmit, Journal of Political Economy  [VoxEU

    How effective is discretion in hiring and promotions? Both rules and discretion can beused, but their relative usefulness is unclear. We collect new data on the performanceof more than 5,800 naval officers serving in the 18th century Royal Navy. Each year the Admiralty promoted a few officers to captain. We find that officers fast-trackedfor promotion performed markedly better than those “passed over” – the Navy picked future winners. Selection was particularly effective for officers connected to the Admiralty through family ties – keeping out the ’wrong’ connected officers and fast-trackinggood connected ones contribute to this result.

  • From Welfare to Warfare: New Deal Spending and Patriotism During World War II [with Bruno Caprettini], Jan 2020 [VoxEU

    Why do people fight for their country? The risks are extreme, the payoff uncertain. In this paper, we argue that reciprocity is a key factor. Examining welfare spending in the US in the 1930s under the New Deal, we show that support for World War II became more common where welfare support had been more generous: war bonds were sold in greater volume, more men and women volunteered, and more soldiers performed heroic actions recognized by a medal. We use weather shocks in the form of droughts to instrument for agricultural emergency relief, and show that results hold. Because both war bond purchases and volunteering respond to welfare support, we argue that results cannot be driven by opportunity cost considerations. Data on World War I patriotic support shows that 1930s emergency spending is only predictive for World War II support. Pre-New Deal droughts are also not correlated with patriotism after 1941. 

  • Bombs, Broadcasts and Resistance: Allied Intervention and Domestic Opposition to the Nazi Regime during World War II [with Maja Adena, Ruben Enikolopov, and Maria Petrova], Jan 2020 [VoxEU

    Can bombs and broadcasts instigate resistance against a foreign regime? In this paper, we examine the canonical case of bombing designed to undermine enemy morale—the Allied bomber offensive against Germany during World War II. Our evidence shows that air power and the airwaves indeed undermined regime support. We collect data on treason trials and combine it with information on the bombing of over 900 German towns and cities. Using plausibly exogenous variation in weather, we show that places that suffered more bombardment saw noticeably more opposition. Bombing also reduced the combat motivation of soldiers: fighter pilots from bombed-out cities performed markedly less well after raids. We also provide evidence that exposure to BBC radio, especially together with bombing, increased the number of resistance cases. We corroborate these findings with the evidence on people’s opinions and behavior using unique survey data collected in 1945. 

  • Going Viral: Propaganda, Persuasion and Polarization in 1932 Hamburg [with Bruno Caprettini, Marcel Caessmann, and David Yanagizawa-Drott], May 2021  

    Propaganda can convince or repel. Social interactions can magnify these effects. We estimate the impact of Nazi marches in 1932 Hamburg, using granular data on all households. Direct exposure immediately affected voting -- propaganda was persuasive. To study diffusion, we measure social connections using contagion patterns from the 1918 Spanish flu, combined with social similarity. Nazi support spread to other parts of the city along the predicted contagion paths. Social spillovers are of similar importance as direct exposure. The marches were also polarizing the electorate â?? in opposition strongholds, they backfired, and gains were concentrated in areas with high Nazi support.

  • Prometheus Shackled: Goldsmith Banks and England's Financial Revolution after 1700 [with Peter Temin], Oxford/New York: Oxford University Press. 2013

    Between 1700 and 1830, the British economy was transformed. It became markedly more industrial, and new industries grew in the North. A famous body of work in economic history attributes the rise of the first industrial nation to the Glorious Revolution of 1688 and associated institutional improvements. In this book, we examine the joint effects of two other factors that characterized the British state fiscal repression and war finance. In combination, these made it impossible for the financial system to perform its most basic function to transfer resources from people with funds to those with ideas. Very far from boosting growth, tight rules on banking and the demands of financing numerous expensive wars did much to stifle growth in the UK. We document how government intervention in financial markets slowed down the Industrial Revolution using evidence from the Hoares Bank archive, demonstrating the effects of the usury laws, partnership limitations, and the demands of war finance.

  • Lending to the Borrower from Hell: Debt, Taxes, and Default in the Age of Philip II [with Mauricio Drelichman], Princeton: Princeton University Press. 2014.

    Why do lenders extend credit to sovereigns despite many defaults in the past, often by the same borrowers? In this book, we examine one famous historical case the debts and defaults of Philip II of Spain. He ruled over one of the largest empires in history. Philip also defaulted four times during his long reign. We first examine his fiscal position. We present the earliest reconstruction of full fiscal accounts in history, and show that Philips debts were sustainable. We also show that lending to him despite the defaults was profitable. What made lending to a powerful monarch possible was a particular network structure amongst lenders effectively a coalition of Genoese bankers who imposed moratoria on the king whenever he defaulted.

  • Time and Work in England, 1750-1830, Oxford: Oxford University Press. 2001.

    Did working hours increase during the Industrial Revolution? Many critics of capitalism believed that long workng hours were one of the main form of exploitation. In this book, I assemble new evidence on working patterns, derived from witnesses accounts in the Old Bailey Session papers. I find that hours worked increased substantially, both because old holidays fell into disuse and because Blue Monday largely disappeared. One important implication is that growth after 1770 was driven by rising labor input the role of productivity growth in explaining overall output performance is correspondingly lower.

  • Rage Against the Machines: Labor-Saving Technology and Unrest in Industrializing England [with Bruno Caprettini], American Economic Review: Insights 2 (2020): 305-20

    Can new technology cause social instability and unrest? We examine the Captain Swing riots in 1830s England. Newly-collected data on threshing machine adoption shows that new technology was associated with both higher unemployment and more riots. We instrument technology adoption with soil suitability for wheat cultivation: IV estimates suggest that threshing machines were an important cause of unrest. Where vibrant labor markets softened the blow of new technology, there was less rioting. [VoxEU] [AEA Research Highlight] [UBS Policy Brief] [LSE Business Review] [British Newspaper Archive]

  • Bowling for Fascism [with Shanker Satyanath, Nico Voigtländer], Journal of Political Economy 125 (2017): 478-526

    Social capital is often associated with desirable political and economic outcomes. This paper contributes to a growing literature on its "dark side". We examine the role of social capital in the downfall of democracy in interwar Germany. We analyze Nazi Party entry in a cross-section of cities, and show that dense networks of civic associations such as bowling clubs, choirs, and animal breeders went hand-in-hand with a rapid rise of the Nazi Party. Towns with one standard deviation higher association density saw at least one-third faster entry. All types of associations veteran associations and non-military clubs, bridging and bonding associations positively predict NS Party entry. Party membership, in turn, predicts electoral success. These results suggest that social capital aided the rise of the Nazi movement that ultimately destroyed Germanys first democracy. We also show that the effects of social capital were more important in the starting phase of the Nazi movement, and in towns less sympathetic to its message. [VoxEU]  

  • Leverage and Beliefs: Personal Experience and Risk Taking in Margin Lending [with Peter Koudijs], American Economic Review 106 (2016): 3367-3400

    What determines risk-bearing capacity and the amount of leverage in financial markets? Using unique archival data on collateralized lending, we show that personal experience can affect individual risk-taking and aggregate leverage. When an investor syndicate speculating in Amsterdam in 1772 went bankrupt, many lenders were exposed. In the end, none of them actually lost money. Nonetheless, only those at risk of losing money changed their behavior markedly they lent with much higher haircuts. The rest continued as before. The differential change is remarkable since the distress was public knowledge. Overall leverage in the Amsterdam stock market declined as a result.

  • Taught to Hate: Nazi Indoctrination and Anti-Semitic Beliefs in Germany [with Nico Voigtländer], 2015, Proceedings of the National Academy of Sciences (PNAS) 112 (2015): 7931-7936

    Attempts at modifying public opinions, attitudes, and beliefs range from advertising and schooling to "brainwashing". Their effectiveness is highly controversial. In this paper, we use survey data on anti-Semitic beliefs and attitudes in a representative sample of Germans surveyed in 1996 and 2006 to show that Nazi indoctrination - with its singular focus on fostering racial hatred - was highly effective. Between 1933 and 1945, young Germans were exposed to anti-Semitic ideology in schools, in the (extracurricular) Hitler Youth, and through radio, print, and film. As a result, Germans who grew up under the Nazi regime are much more anti-Semitic than those born before or after that period: The share of committed anti-Semites, who answer a host of questions about attitudes towards Jews in an extreme fashion, is 2-3 times higher than in the population as a whole. Results also hold for average beliefs, and not just the share of extremists - average views of Jews are much more negative among those born in the 1920s and 1930s. Nazi indoctrination was most effective where it could tap into pre-existing prejudices - those born in districts that supported anti-Semitic parties before 1914 show the greatest increases in anti-Jewish attitudes. These findings demonstrate the extent to which beliefs can be modified through policy intervention. We can also identify parameters that amplify the effectiveness of such measures - such as pre-existing prejudices.

  • State Capacity and Military Conflict [with Nicola Gennaioli],  Review of Economic Studies 82 (2015): 1409-48.

    In 1500, Europe was composed of hundreds of statelets and principalities, with weak central authority, no monopoly over the legitimate use of violence, and multiple, overlapping levels of jurisdiction. By 1800, Europe had consolidated into a handful of powerful, centralized nation states. We build a model that simultaneously explains both the emergence of capable states and growing divergence between European powers. In our model, the impact of war on the European state system depends on: i) the importance of money for determining the war outcome, and ii) a country's initial level of domestic political fragmentation. We emphasize the role of the "Military Revolution", which raised the cost of war. Initially, this caused more internally cohesive states to invest more in state capacity, while other (more divided) states rationally dropped out of the competition. This mechanism leads to both increasing divergence between European states, and greater average investments in state building on the continent overall.

  • Numeracy and the Impact of High Food Prices in Industrializing Britain, 1780-1850' [with Jörg Baten, Dorothee Crayen], Review of Economics and Statistics 96 (2014): 418-30.

    Using census-based data on the ability to recall ones age, we show that low levels of nutrition impaired numeracy in industrializing England, 1780 to 1850: cognitive ability declined among those born during the Napoleonic wars. The effect was stronger in areas where grain was expensive and relief for the poor, an early form of welfare support was limited. Nutritional shortages had a nonlinear effect on numeracy, with, severe shortages impairing numeracy more. Nutrition during childhood also mattered for labor market outcomes: individuals born in periods or counties with low numeracy typically worked in occupations with lower earnings.

  • How the West 'Invented' Fertility Restriction [with Nico Voigtländer], American Economic Review 103 (2013): 2227-64.

    We analyze the rise of the first socio-economic institution in history that limited fertility long before the Demographic Transition. The "European Marriage Pattern" (EMP) raised the marriage age of women and ensured that many remained celibate, thereby reducing childbirths by up to one third between the 14th and 18th century. To explain the rise of EMP we build a two-sector model of agricultural production grain and livestock. Women have a comparative advantage in the latter because plow agriculture requires physical strength. After the Black Death in 1348-50, land abundance triggered a shift towards the land-intensive pastoral sector, improving female employment prospects. Because women working in animal husbandry had to remain unmarried, more farm service spelled later marriages. The resulting reduction in fertility led to a new Malthusian steady state with lower population pressure and higher wages. The model can thus help to explain the divergence in income per capita between Europe and Asia long before the Industrial Revolution. Using detailed data from England after 1290, we provide strong evidence for our mechanism. Where pastoral agriculture dominated, more women worked as servants, and marriage occurred markedly later. Overall, we estimate that pastoral farming raised female ages at first marriage by more than 4 years.

  • The Three Horsemen of Riches: Plague, War and Urbanization in Early Modern Europe [with Nico Voigtländer], Review of Economic Studies 80 (2013): 774-811.

    How did Europe escape the Iron Law of Wages? We construct a simple Malthusian model with two sectors and multiple steady states, and use it to explain why European per capita incomes and urbanization rates increased during the period 13501700. Productivity growth can only explain a small fraction of the rise in output per capita. Population dynamicschanges of the birth and death scheduleswere far more important determinants of steady states. We show how a major shock to population can trigger a transition to a new steady state with higher per-capita income. The Black Death was such a shock, raising wages substantially. Because of Engel's Law, demand for urban products increased, and urban centers grew in size. European cities were unhealthy, and rising urbanization pushed up aggregate death rates. This effect was reinforced by diseases spread through war, financed by higher tax revenues. In addition, rising trade also spread diseases. In this way higher wages themselves reduced population pressure. We show in a calibration exercise that our model can account for the sustained rise in European urbanization as well as permanently higher per capita incomes in 1700, without technological change. Wars contributed importantly to the Rise of Europe, even if they had negative short-run effects. We thus trace Europe's precocious rise to economic riches to interactions of the plague shock with the belligerent political environment and the nature of cities.

  • Persecution Perpetuated: The Medieval Origins of Anti-Semitic Violence in Nazi Germany [with Nico Voigtländer], Quarterly Journal of Economics 127 (2012): 1339-1392.

    How persistent are cultural traits? Using data on anti-Semitism in Germany, we find local continuity over 600 years. Jews were often blamed when the Black Death killed at least a third of Europes population during 134850. We use plague-era pogroms as an indicator for medieval anti-Semitism. They reliably predict violence against Jews in the 1920s, votes for the Nazi Party, deportations after 1933, attacks on synagogues, and letters to Der Stürmer. We also identify areas where persistence was lower: cities with high levels of trade or immigration. Finally, we show that our results are not driven by political extremism or by different attitudes toward violence.

  • Lending to the Borrower from Hell: Debt and Default in the Age of Philip II, 1556-1598 [with Mauricio Drelichman], Economic Journal 121 (2011): 1205-1227 (lead article).

    What sustained borrowing without third-party enforcement in the early days of sovereign lending? Philip II of Spain accumulated towering debts while stopping all payments to his lenders four times. How could the sovereign borrow much and default often? We argue that bankers ability to cut off Philip IIs access to smoothing services was key. A form of syndicated lending created cohesion among his Genoese bankers. As a result, lending moratoria were sustained through a cheat-the-cheater mechanism. Our article thus lends empirical support to a recent literature that emphasizes the role of bankers incentives for continued sovereign borrowing.

  • Serial Defaults, Serial Profits: Returns to Sovereign Lending in Habsburg Spain , 1566-1600 [with Mauricio Drelichman], Explorations in Economic History 48 (2011): 1-19 (lead article).

    Philip II of Spain accumulated debts equivalent to 60% of GDP. He also defaulted four times on his short-term loans, thus becoming the first serial defaulter in history. Contrary to a common view in the literature, we show that lending to the king was profitable even under worst-case scenario assumptions. Lenders maintained long-term relationships with the crown. Losses sustained during defaults were more than compensated by profits in normal times. Defaults were not catastrophic events. In effect, short-term lending acted as an insurance mechanism, allowing the king to reduce his payments in harsh times in exchange for paying a premium in tranquil periods.

  • The Sustainable Debts of Philip II: A Reconstruction of Castile's Fiscal Position, 1566-1596 [with Mauricio Drelichman], Journal of Economic History 70 (2010): 813-42.

    The defaults of Philip II have attained mythical status as the origin of sovereign debt crises. We reassess the fiscal position of Habsburg Castile, deriving comprehensive estimates of revenue, debt, and expenditure from new archival data. The king's debts were sustainable. Primary surpluses were large and rising. Debt-to-revenue ratios remained broadly unchanged during Philip's reign. Castilian finances in the sixteenth century compare favorably with those of other early modern fiscal states at the height of their imperial ambitions, including Britain. The defaults of Philip II therefore reflected short-term liquidity crises, and were not a sign of unsustainable debts.

  • Betting on Hitler: The Value of Political Connections in Nazi Germany [with Thomas Ferguson], Quarterly Journal of Economics 123 (2008): 101-137.

    This paper examines the value of connections between German industry and the Nazi movement in early 1933. Drawing on previously unused contemporary sources about management and supervisory board composition and stock returns, we find that one out of seven firms, and a large proportion of the biggest companies, had substantive links with the National Socialist German Workers' Party. Firms supporting the Nazi movement experienced unusually high returns, outperforming unconnected ones by 5% to 8% between January and March 1933. These results are not driven by sectoral composition and are robust to alternative estimators and definitions of affiliation.

  • Interest Rate Restrictions in a Natural Experiment: Loan Allocation and the Change in the Usury Laws in 1714 [with Peter Temin], Economic Journal 118 (2008): 743-58.

    This article studies the effects of interest rate restrictions on loan allocation. The British government tightened the usury laws in 1714, reducing the maximum permissible interest rate from 6% to 5%. A sample of individual loan transactions reveals that average loan size and minimum loan size increased strongly, while access to credit worsened for those with little social capital. Collateralised credits, which had accounted for a declining share of total lending, returned to their former role of prominence. Our results suggest that the usury laws distorted credit markets significantly; we find no evidence that they offered a form of Pareto-improving social insurance.

  • Why England? Demographic Factors, Structural Change and Physical Capital Accumulation during the Industrial Revolution [with Nico Voigtländer], Journal of Economic Growth 11 (2006): 319-61.

    Why did England industrialize first? And why was Europe ahead of the rest of the world? Unified growth theory in the tradition of Galor and Weil (2000, American Economic Review, 89, 806828) and Galor and Moav (2002, Quarterly Journal of Economics, 177(4), 11331191) captures the key features of the transition from stagnation to growth over time. Yet we know remarkably little about why industrialization occurred much earlier in some parts of the world than in others. To answer this question, we present a probabilistic two-sector model where the initial escape from Malthusian constraints depends on the demographic regime, capital deepening and the use of more differentiated capital equipment. Weather-induced shocks to agricultural productivity cause changes in prices and quantities, and affect wages. In a standard model with capital externalities, these fluctuations interact with the demographic regime and affect the speed of growth. Our model is calibrated to match the main characteristics of the English economy in 1700 and the observed transition until 1850. We capture one of the key features of the British Industrial Revolution emphasized by economic historians slow growth of output and productivity. Fertility limitation is responsible for higher per capita incomes, and these in turn increase industrialization probabilities. The paper also explores the availability of nutrition for poorer segments of society. We examine the influence of redistributive institutions such as the Old Poor Law, and find they were not decisive in fostering industrialization. Simulations using parameter values for other countries show that Britains early escape was only partly due to chance. France could have moved out of agriculture and into manufacturing faster than Britain, but the probability was less than 25%.Contrary to recent claims in the literature, 18th century China had only a minimal chance to escape from Malthusian constraints.

  • Riding the South Sea Bubble [with Peter Temin], American Economic Review 94 (2004): 1654-68.

    This paper presents a case study of a well-informed investor in the South Sea bubble. We argue that Hoare's Bank, a fledgling West End London bank, knew that a bubble was in progress and nonetheless invested in the stock: it was profitable to "ride the bubble." Using a unique dataset on daily trades, we show that this sophisticated investor was not constrained by such institutional factors as restrictions on short sales or agency problems. Instead, this study demonstrates that predictable investor sentiment can prevent attacks on a bubble; rational investors may attack only when some coordinating event promotes joint action.

  • With a Bang, Not a Whimper: Pricking Germany's "Stockmarket Bubble" in 1927 and the Slide into Depression, Journal of Economic History 63 (2003): 65-99.

    In May 1927, the German central bank intervened indirectly to reduce lending to equity investors. The crash that followed ended the only stock market boom during Germanys relative stabilization 1924-28. This paper examines the factors that lead to the intervention as well as its consequences. We argue that genuine concern about the exuberant level of the stock market, in addition to worries about an inflow of foreign funds, tipped the scales in favour of intervention. The evidence strongly suggests that the German central bank under Hjalmar Schacht was wrong to be concerned about stockprices-there was no bubble. Also, the Reichsbank was mistaken in its belief that a fall in the market would reduce the importance of short-term foreign borrowing, and help to ease conditions in the money market. The misguided intervention had important real effects. Investment suffered, helping to tip Germany into depression.

  • Factor Prices and Productivity Growth during the British Industrial Revolution [with Pol Antras, Explorations in Economic History 40 (2003): 52-77.

    This paper presents new estimates of total factor productivity growth in Britain for the period 17701860. We use the dual technique and argue that the estimates we derive from factor prices are of similar quality to quantity-based calculations. Our results provide further evidence, calculated on the basis of an independent set of sources, that productivity growth during the British Industrial Revolution was relatively slow. The CraftsHarley view of the Industrial Revolution is thus reinforced. Our preferred estimates suggest a modest acceleration after 1800.

  • Human Capital, Equipment Investment, and Industrialization [with Jon Temple], European Economic Review 42 (1998): 1343-62.

    This paper constructs simple models in which industrialization is driven by human capital accumulation. Industrialization can explain the robust correlation between equipment investment and growth in developing countries. We show that government intervention is justified within our stylized model, and indicate that a subsidy to equipment investment is likely to be dominated by other policies. In the final section of the paper, we examine the correlation between equipment investment and growth, and find that it is strongest in economies on the brink of industrialization. We also show that this result is not easily explained by diminishing returns.

  • Time and Work in Eighteenth Century London , Journal of Economic History 58 (1998): 29-58.

    Witnesses' accounts are used to analyze changes in working hours between 1750 and 1800. Two findings stand out. The article demonstrates that the information contained in witnesses' accounts allows us to reconstruct historical time-budgets and provides extensive tests of the new method. Estimates of annual labor input in 1749/63 and 1799/1803 are presented. It emerges that the number of annual working hours changed rapidly between the middle and the end of the eighteenth century. These findings have important implications for the issue of total factor productivity during the Industrial Revolution.
