ANALYSIS OF HOUSEWIVES' GROCERY SHOPPING BEHAVIOR IN TAIWAN: AN APPLICATION OF THE POISSON SWITCHING REGRESSION

The purpose of this study is to empirically investigate Taiwanese married women's grocery shopping behavior in relation to their labor force participation status. In this study, focus is limited to their grocery shopping frequency which is meant to be a proxy for an input to household production, i.e., food at home. A Poisson switching regression model is developed to estimate parameters of married women's shopping behavior. The results show that the labor force participation status does have a great impact on time allocation behavior.
