This paper consists of two analyses related to the economic activities of Korean women farmers. One is to analyze the factors affecting the determination of their farm labor hours. The other is to examine the factors affecting the likelihood of their off-farm enterprise commencement. Measurements are obtained from the estimations of a Heckman’s two stage estimation and a logit model, respectively. The national survey data for the Korean women farmers’ situation conducted in 2003 is used. The empirical evidence suggests that the women farmers in their 40s and 50s relatively work more on farms, especially horticulture, while relatively younger women farmers are more willing to start off-farm work. The result also finds that the heavy burden of housework is a constraint blocking all economic activities of women farmers.
