Traditional models in the agricultural labor literature have examined agricultural labor supply in terms of a labor-lei sure trade-off by a single individual. This work examines the question of total annual market days in farm and nonfarm work of secondary family workers engaged in hired farm work. The underlying model is one of home production-consumption. A trade-off of market days between wife and older children in a family is hypothesized. Empirical results are mixed, generally supporting a tradeoff in the supply of market days in a family between nonstudents and wives, but not between students and wives.
