During the seventeenth and eighteenth centuries a variety of labor market institutions developed to facilitate the movement of labor in response to the opportunities created by American factor proportions. While some immigrants migrated on their own, the majority of immigrants were either indentured servants or African slaves.
Because of the cost of passage—which exceeded half a year’s income for a typical British immigrant and a full year’s income for a typical German immigrant—only a small portion of European migrants could afford to pay for their passage to the Americas (Grubb 1985a). They did so by signing contracts, or “indentures,” committing themselves to work for a fixed number of years in the future—their labor being their only viable asset—with British merchants, who then sold these contracts to colonists after their ship reached America. Indentured servitude was introduced by the Virginia Company in 1619 and appears to have arisen from a combination of the terms of two other types of labor contract widely used in England at the time: service in husbandry and apprenticeship (Galenson 1981). In other cases, migrants borrowed money for their passage and committed to repay merchants by pledging to sell themselves as servants in America, a practice known as “redemptioner servitude (Grubb 1986). Redemptioners bore increased risk because they could not predict in advance what terms they might be able to negotiate for their labor, but presumably they did so because of other benefits, such as the opportunity to choose their own master, and to select where they would be employed.
Although data on immigration for the colonial period are scattered and incomplete a number of scholars have estimated that between half and three quarters of European immigrants arriving in the colonies came as indentured or redemptioner servants. Using data for the end of the colonial period Grubb (1985b) found that close to three-quarters of English immigrants to Pennsylvania and nearly 60 percent of German immigrants arrived as servants.
A number of scholars have examined the terms of indenture and redemptioner contracts in some detail (see, e.g., Galenson 1981; Grubb 1985a). They find that consistent with the existence of a well-functioning market, the terms of service varied in response to differences in individual productivity, employment conditions, and the balance of supply and demand in different locations.
