  • Gilded Apartheid: Market Access & the Forging of Afrikaner National Identity in Colonial South Africa
  • Abstract: Do markets make or break nations? I study the impacts of increases in market integration on rural white-settlers’ national identity choice following the world’s largest mineral revolution in colonial South Africa. For causal identification, I exploit time and geographical variation in local market access driven by the expansion of a transportation network designed to reach diamond and gold deposits located in ex-ante quasi-random locations. I find that higher local access to nonwhite labor markets increases white settlers’ marginal value of institutionalizing racial segregation to coercively retain workers in farms amid the mines’ rising demand for labor, prompting identification with the Afrikaner who support these policies. Conversely, lower local access to nonwhite labor markets encourages labor-saving capital investments, increasing the marginal cost of not identifying with the British who dominate world capital markets and outlaw institutionalized racial segregation.

  • Indemnitaires and Obligataires: The Means and Meaning of Haiti's Debt in Nineteenth-century France
  • Abstract: This talk stems from Alexia Yates’s current book project on the practices and cultures of investment in nineteenth-century France. France’s recognition of Haitian independence in 1825 included the imposition of an enormous indemnity payment from Haiti to former colonists, and the obligation to find the necessary funds by borrowing from French banks. These arrangements transformed former colonial property in people and land into a national debt that perpetuated, in various forms, into the twentieth century. Assessing the work of Haiti’s French creditors across this period as they lobbied for payment, this talk approaches the debt as a structure that institutionalized principles and mechanisms important to France’s modern economic imperialism, analyzing how investors large and small engaged themselves and the French public in debates about the value of that imperialism.

  • Expertise and prejudice: British economists’ memoranda to the Royal Commission on Equal Pay, 1944-1946
  • Abstract: In 1944, the British War Cabinet set up a Royal Commission on Equal Pay to examine whether equal pay between men and women should be implemented for the civil services and across industries in general. The Commissioners reviewed an impressive amount of evidence, testimonies, and reports, among which memoranda from ten economists—Philip Sargant Florence, Roy F. Harrod, John R. Hicks, Hubert D. Henderson, Arthur C. Pigou, Joan Robinson, David H. MacGregor, David Ross, Hamilton Whyte, and Barbara Wootton. After the publication of the report in 1946, equal pay for equal work was not granted to civil servants and not advocated as an organizing principle of labour markets. The first section describes the origins, context, and content of the 200-pages report. Section 2 is devoted to the arguments presented by the ten economists in favour and against the principle of equal pay for equal work. The last section ponders the political weight of arguments from economists, medical doctors, and other scientists, as well as the political instrumentalization of the commission itself, and concludes on the relatively low relevance of economic expertise at the time, in comparison to moral and medical arguments.

  • The Economy, The Ghost in Your Gene and the Escape from Premature Mortality
  • Abstract: Explanations for the West’s escape from premature mortality have focused on chronicmalnutrition or income and on public health or state capacity. We argue that by ignoringthe multigenerational effects of variance in ancestors’ harvests, we are underestimatingthe contribution of modern economic growth to the escape from early death at older ages.Using two multigenerational datasets for Sweden, we show that grandsons’ longevity wasstrongly linked to spatial shocks in paternal grandfathers’ yearly harvest variability whenagricultural productivity was low and market integration was limited. We reason that anepigenetic mechanism is the most plausible explanation for our findings. We posit thatthe removal of trade barriers, improvements in transportation, and agricultural innovationreduced harvest variability. We contend that for older Swedish men (but not women) whoreached age 40 between 1870 and 1919 this reduction was as important as decreasingcontemporaneous infectious disease rates and more important than eliminating exposureto poor harvests in-utero. Decreasing contemporaneous infectious disease ratesdominated reductions in paternal grandfathers’ harvest variability for men reaching age 40 between 1920 and 1949.

  • State Capacity and the (In)Effectiveness of Medical Technology: The Difficult Path to Safe and Reliable Vaccination in Victorian Britain
  • Abstract: This study investigates why smallpox remained endemic in Britain into the twentieth century, despite the discovery of an effective vaccine in 1796 and high vaccination rates from the 1850s onward. Using newly digitized data on local mortality and vaccination outcomes, it shows that the effectiveness and safety of vaccination improved only gradually—and only after repeated state intervention. Poor implementation often rendered vaccination ineffective until the 1870s, and it remained relatively unsafe until the early twentieth century. A triple-difference analysis shows that the introduction of government quality standards—supported by inspections and performance-based incentives—was critical to making vaccination effective. The paper underscores that state capacity, rather than medical technology alone, determined the success of early public health interventions.

  • An Economic Theory of Salvation Religions
  • Abstract: This paper constructs a unified model that micro-founds the three types from Max Weber’s typology of world religions, i.e., “mystic religions,” “activist religions,” and “religions of world adjustment.” We then employ the model to study the interaction between world religions and secular institutions. Among others, the model shows that salvation religions might have played a role in the great “reversal of fortune” between the East and the West. Because China and India were the economic powerhouses in the Middle Ages, they might have failed to sustain religious activism that facilitated modern economic growth and constitutional government in Western Europe. The model further interprets competition over socioeconomic status as a partial substitution of salvation religions, explaining why status competition is fierce where the influence of salvation religions have declined

  • Africa Descending and Rising: Revisiting the external causes of post-independence growth cycles
  • Abstract: This paper returns to a much-debated question in African development economics: how and why Africa's post-independence growth has been so closely tied to the global commodity price cycle, with a severe economic collapse when commodity prices fell in the 1980s and a recovery in growth and commodity prices in the 2000s. We ask how much of the recovery in growth and fiscal performance in the 2000s can be attributed to terms of trade improvements and capital inflows, and how the external drivers of the crisis and recovery differed between Africa and other developing regions. We also consider how external conditions shaped policy, and question the extent to which better macroeconomic management can be disentangled from the global market conditions which widened the policy space and made it politically feasible to follow the Washington advice.

  • The Origins of Generosity and Racial Exclusion in the American Welfare System
  • Abstract: What are the origins of U.S. welfare generosity?  Using newly digitized historical welfare records from the early 20th century, we show that although nearly all states passed welfare by 1930, only 37% of counties ever administered any transfers.  Counties with more immigrants were more generous whereas counties with large black populations were less likely to have programs. Local political leanings and the women’s movement also appeared to have some, but not large, effects on early welfare passage and generosity, in line with previous work. Despite sweeping racial and political shifts over the last century, we find that the most generous states in the 1910s and 1920s remain the most generous states today, and explore why.
