Patterns of Everyday Exchange: Big Historical Data and the Case of the Basel Advertisement Paper, 1729–1844.

With concepts like the consumer revolution or the industrious revolution, the changing behaviour of private households in the 18^th and early 19^th centuries has become of great interest. The article suggests a new way to observe intentions and decisions, by utilizing a database of 850,000 classified ads from the Basel Avisblatt over a span of 116 years. Changes in food prices constantly altered the discretionary income of households, which forced budget-related decisions. By cross-correlating indicators of discretionary income with the changing number of different types of ads, patterns of utilizing the Avisblatt can be identified, and strategies to stabilize discretionary income deduced.
