In this paper the author develops and tests a model of regional responses to national business-cycles. The model divides cyclical decline in each state into two sectors: a basic sector and a nonbasic sector. The industrial mix, capital—labor ratio, age of capital stock, level of unemployment insurance benefits, labor shortage, and extent of labor-force unionization of a state are hypothesized to influence the response to national recessions by the economy of a state. Employment decline in the nonbasic sector of the economy of a state is a function of employment decline in basic industries and is transmitted through a short-run multiplier. The model is tested on data from five post World War 2 recessions between 1950 and 1975. The findings indicate that industry mix at the two-digit Standard Industrial Code level explains 36% of the across-state variation in cyclical employment. The results also indicate that an old capital-stock, a nonunion labor force, and generous unemployment insurance benefits promote cyclical stability in state economies.
