Between 1660 and 1815 the combat fatality rate among British navy captains fell by 98 percent, even as the combat success of the British Navy rose dramatically. Both developments can be explained as a result of learning by doing among British commanders. This learning was importantly driven by the extensive wartime experience accumulated over this period, combined with the unparalleled financial incentives for combat success offered to British commanders.

The mortality of enslaved Africans in the Atlantic crossing has long preoccupied historians but the relationship between slave traders' purchasing strategies and slave mortality rates in transit has escaped close investigation. We address these issues by using records of 39 eighteenth-century voyages of the Dutch Middelburgsche Commercie Compagnie. These allow shipboard mortality rates of enslaved Africans to be estimated. They also reveal previously un-noticed age- and gender-based variations in slave purchase and mortality patterns, which in turn shed light on the relative importance of African and shipboard conditions in determining slave survival rates in the middle passage.

Prior to the modern civil rights movement of the 1960s, the pay gap between African-American and white workers in the South was large overall, but also quite variable across location. Using 1940 census data, I estimate the white-black earnings gap of men for separate county groups called state economic areas, adjusting for individual differences in schooling and experience. I show that the gap was significantly greater in areas where, ceteris paribus, blacks were a larger proportion of the workforce, plantation institutions were more prevalent, more of the population was urban, and white voters exhibited segregationist preferences.

During the 1920s the New York Stock Exchange's position as the dominant American exchange was eroding. Costs to customers, measured as bid-ask spreads, spiked when surging inflows of orders collided with the constraint created by a fixed number of brokers. The NYSE's management proposed and the membership approved a 25 percent increase in the number of seats by issuing a quarter-seat dividend to all members. An event study reveals that the aggregate value of the NYSE rose in anticipation of improved competitiveness. These expectations were justified as bid-ask spreads became less sensitive to peak volume days.

This article examines changes in institutions that protected property rights in the Alps between the thirteenth and the nineteenth century and, in particular, alternative management systems adopted for the common pastures and forests in about 200 communities. Over time, private-order institutions in the form of charters replaced informal arrangements sustained by the long-run interaction among villagers. Although costly to run, the charters accomplished several tasks that increased resource use efficiency.

The liturgical system in Classical Athens (479–322 BCE) privately provided public goods, including naval defense. I use it to evaluate mechanism design policies and to address uncertainties in the historical record by adding predictive economic theory to research by ancient historians. I evaluate the system's success at meeting the conflicting goals of efficiency, feasibility, and budget balance by analyzing the Athenian citizens' incentives within a game of asymmetric information. In the game, multiple equilibria occur; citizens may or may not volunteer for duty or avoid it. I relate the game theoretic findings to historical events.

The security of property rights is fragile under dictatorships. This is particularly so if economic agents are uncertain as to whether the regime will last. As a result, private investment is withheld and economic performance is poor. Spain was in such a situation after World War II. However, as the Cold War intensified the United States became interested in Spain as a military ally, thereby helping to consolidate Franco's regime. This led to an increase in economic confidence and helps to explain why economic growth resumed in Spain ahead of significant changes in its autarkic economic policies.

This article uses nineteenth-century evidence to calculate the impact of early exposure to malaria-ridden environments on nutritional status and the immune system in America. I estimate the risk of contracting malarial fevers in the 1850s by using correlations between malaria and environmental factors such as climate and geographical features. The study demonstrates that Union Army recruits who spent their early years in malaria-endemic counties were 1.1 inches shorter at enlistment due to malnutrition and were 13 percent more susceptible to infections during the U.S. Civil War as a result of immune disorders than were those from malaria-free regions.

The article employs a general equilibrium model to describe Italy's response to commodity and factor market integration during the expansion of the Roman Empire. This novel approach constructs a comprehensive story of the Italian economy that corroborates established developments and sheds light on controversial and unanswered questions. The success of the model supports arguments that Romans were rational economic actors and that the Roman economy was a well-integrated market system.

The active opposition to technical change has frequently impeded economic growth. This article examines the widespread resistance to government-led campaigns to use new tuberculin testing technologies to eradicate bovine tuberculosis in the United States. We explore three issues: the political economy of opposition; the role of earlier scientific controversies in the discourse; and the techniques used by the opponents. Over time, the protests shifted from challenging the scientific merits of the testing technology to more nuts-and-bolts distributional and administrative issues.
