The intellectual origins of the Industrial Revolution are traced back to the Baconian program of the seventeenth century, which aimed at expanding the set of useful knowledge and applying natural philosophy to solve technological problems and bring about economic growth. The eighteenth-century Enlightenment in the West carried out this program through a series of institutional developments that both increased the amount of knowledge and its accessibility to those who could make best use of it. Without the Enlightenment, therefore, an Industrial Revolution could not have transformed itself into the sustained economic growth starting in the early nineteenth century.

How did the wartime health of Union Army recruits affect their wealth accumulation through 1870? Wounds and exposure to combat had strong negative effects on subsequent savings, as did illnesses while in the service. The impact of poor health was particularly strong for unskilled workers. Health was a powerful determinant of nineteenth-century economic mobility. Infectious diseases' influences on wealth accumulation suggest that the economic gains from the improvement of the disease environment should be enormous. The direct economic costs of the Civil War were probably much greater than previously thought, given the persistent adverse health effects of wartime experiences.

The prudent peasant mitigated the risk of crop failures by scattering his arable land throughout his village, Deirdre McCloskey argued, because alternative risk-sharing institutions did not exist. But, alternatives did exist, this essay concludes. Medieval English peasants formed two types of farmers' cooperatives. Fraternities protected members from the perils of everyday life. Customary poor laws redistributed resources towards villagers beset by bad luck. In both institutions, the expectation of reciprocation motivated farmers with surpluses to aid neighbors with shortages.

In the United States a century ago, working children turned over almost all of their earnings to their parents. What incentives, then, did they have to work? Standard answers include altruism or the “sticks” wielded by parents and employers. This article argues that there were also “carrots”: working gave children greater influence in household decision making. Using data from the Bureau of Labor Statistics Cost of Living Survey 1917–1919, this article shows that working children had higher clothing expenditures than did nonworking children and that clothing expenditures were increasing in the income a child brought into the household.

Turnpike trusts were private organizations that financed road improvements by levying tolls and issuing mortgage debt. They were established by Acts of Parliament throughout the seventeenth, eighteenth, and early nineteenth centuries. The acts transferred authority from parishes to a body of trustees, composed of local landowners and merchants. Parishes financed road improvements with local property taxes; but they could not levy tolls. This article uses a new data set to show that turnpike trusts increased road expenditure, rather than replacing existing or forthcoming parish expenditure. It also illustrates how institutional changes contributed to the process of economic development in England.

The transition from sailing ship to steamship is analyzed for European immigrants arriving at New York City. Based on information taken from the U.S. Passenger Lists, new estimates of the timing and length of the transition are provided. Though the accepted model suggests the changeover from sail to steam could occur in only a few years, it actually took about 15 years in the Europe to New York immigrant trade. The slow transition is found to be due to slow construction of new steamships given uncertainty concerning immigrant volume and new steamship technology.

The most important change in nineteenth century emigrant transportation was that from sail to steam.

…the transition from sail to steam in the transatlantic immigrant trade was an event of enormous significance for the history of immigration.

Long-distance trade depends crucially on the enforcement of long-distance contracts, those in which principals are significantly removed from agents. The problem of contract enforcement in the English East India Company reflected a multi-task principal-agent problem in which servants traded publicly for the company and at the same time conducted their own private trade. Private trade, sustained by the private use of company resources, and dismissals were the mechanisms that made East India contracts work. Mechanisms that served little purpose were salaries and pre-employment bonds.
