A sample of patent records from the United States between 1790 and 1846 is employed to study the patterns in inventive activity. Patenting was pro-cyclical, and yet began to grow rapidly with the interruptions in foreign trade that preceded the War of 1812. A strong association between patenting and proximity to navigable waterways is also demonstrated. Although the importance of specific mechanisms remains unclear, both the temporal and cross-sectional evidence imply that inventive activity was positively related to the growth of markets during early industrialization.

This article demonstrates that new industrial technology caused a revolutionary decline in nineteenth-century freight rates. This overturns Douglass North's well-known conclusion that organizational improvements were the dominant source of savings. While North's American freight rate series declines prior to the use of the metal steamship, British rates decline only modestly prior to 1850 and then rapidly as metal steamships come into use. Cotton freights dominate North's index and declined when cotton became more tightly packed for shipment. Metal ships and steam propulsion, however, caused a general decline in freight rates after 1850.

The thesis that free banking laws lowered barriers to entry in the U.S. banking industry is tested by examining entry of firms and output of banking services before and after the institution of free banking. The output of banking services and the number of banks remained the same or declined after the institution of free banking, in all states with viable free banking laws except New York. In light of this evidence, the belief that free banking in the antebellum United States increased competition and efficiency of the banking industry by lowering barriers to entry must be reconsidered.

This article explores differences between the cotton industries in England and America in the early nineteenth century. I show that the two countries produced almost entirely different products: the Enlish made fine fabrics; the Americans, coarse. The cause of this disjunction is found in the American tariff policy, whichwas influenced by the Massachusetts cotton manufacturers. Since coarse spinning promoted vertical integration, the American product structure favored integration. This argument reveals that the variables analyzed were jointly determined, since the Massachusetts firms with the political clout to affect the tariff were vertically integrated.
