This study distinguishes two nonseparable agricultural household models for a self-employed farm household. One assumes heterogeneity of farm and nonfarm labor and a competitive market for nonfarm labor. The other assumes homogeneity of the two types of labor and a restricted market for nonfarm labor. We compare demand systems that are derived from them, which have different dependent variables and different numbers of equations. We apply a Cox-type test to compare these complicated nonnested systems. Results show clearly that the former is better for Japanese rice-farming households. Comparison of price elasticities for those models verifies the importance of that test. © 2008 American Agricultural Economics Association.

This article presents an empirical method for a simple model of self-employed households. In this model, the “internal wage” plays a crucial role of equilibrating the demand and supply of family labor within the household. By paying special attention to this wage, all structural parameters of the model can be estimated and are used to verify the seemingly anomalous characteristics of self- employed households: They earn less (per hour or week) and work longer than salary and wage workers and their own price elasticity of output supply is small or negative. © 2002 American Association of Family and Consumer Sciences.
