This article emphasizes the role of nonprice rationing in credit crunches. It proposes a process for identifying credit crunches that is centered around the political economy of the period under study. The process is applied to the 1960-91 period, and a variable is constructed that indicates when credit crunches occurred. In addition, the article questions the conventional wisdom that Regulation Q was the primary cause of the 1960s credit crunches.
