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.Household production, Labor supply rationing, Poisson switching regression, Shopping frequency, Time allocation, Consumer/Household Economics,

ACREAGE PLANTING DECISION ANALYSIS OF SOUTH CAROLINA TOMATOES: NERLOVIAN VERSUS JUST RISK MODEL

Factors which explain supply response behavior of South Carolina tomato growers were determined. Two well known supply response models were used for comparison: the Nerlovian structural model and the Just risk model. The Just risk model reflected the significance of the risk effect in both stable and unstable periods. An evaluation of forecasting power between the two models was indeterminate. Growers are apparently willing to invest in more information with increased market instability because growers were influenced by the Florida winter price of tomatoes in planting decisions during the period of instability.Crop Production/Industries,
