| Abstract: | This paper examines the effects of off-farm employment on grain marketable surplus supply during the reform period in China. A theoretical framework demonstrates that farm households' supply behaviour depends not only on the profitability of farm production but also on alternative off-farm wage opportunities of household members. An empirical model, which assumes full income maximisation of farm households, simultaneously evaluates the effects of on-farm and off-farm income on their grain supply behaviour. Particular attention is paid to the effect of off-farm income through a comparison of conditional and unconditional grain marketable surplus supply elasticities. Results show that off-farm income had a strong negative effect on grain marketable surplus from farm households following liberalisation of factor markets in China and that this could lead to a loss of marketable surplus supply. |
