THE IMPACT OF NEGATIVITY ON SEPARABILITY TESTING

James S. Eales and Jason R. Henderson

No 21817, 2000 Annual meeting, July 30-August 2, Tampa, FL from American Agricultural Economics Association (New Name 2008: Agricultural and Applied Economics Association)

Abstract: While performing separability tests, studies rarely checked negativity to ensure the appropriate curvature of the expenditure function. The effect of imposing negativity on the results of separability tests is examined. Findings indicate that imposing negativity can affect separability tests in demand systems that do not spontaneously satisfy the curvature restriction.
