We apply seasonal unit root tests to apple and pear price and quantity data. We then develop a method for testing shifts in amplitude andjor phase of the seasonal cycles. The results have implications to econometric specifications of models which use short-run data (quarterly, monthly).

This paper presents a model of estimated demand for four tobacco products: cigarettes, cigars, chewing tobacco, and smoking tobacco products. Own elasticities and cross-price elasticities are used to obtain insights into the effectiveness and implications of new policy measures. Of particular...

This paper generalizes the standard error correction model and applies this more general modeling procedure to an analysis of the spinach e-coli outbreak on consumer demand.

This study used a new body of quarterly data to estimate multilateral import demand relations for soybeans and soymeal. The countries of origin were the United States, Brazil, and Argentina. The areas of destination were the EEC, Japan, and Eastern Europe. The results indicated that own- and...

We extend the methodology of a two-step profit function to obtain area and yield elasticities. We then estimate the effects of price and technology on crop output of France, Germany, and the UK. Area elasticities were obtained by adding area shadow price equations to the standard dual model of...

The assumption in standard expected utility model formulations that the coefficient of risk aversion is a constant is potentially unrealistic. This study takes the standard linear expected meanvariance problem and replaces the coefficient of risk aversion with a function of risk aversion,...

Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and their feed consumed are examined using a generalized McFadden dual cost function. Results demonstrate systematic differences in demand relationships among different weight categories. Positive...

We estimate an error correction model representing demand for leafy green vegetables but generalize the structure to allow for adjustment to one conspicuous shock. We investigate whether the adjustment rate to the U.S. Food and Drug Administration’s (FDA) 2006 warning that fresh spinach...
