We use panel data from two experiments conducted five months a part to investigatethe stability of individual preferences and aggregate demand for five types of fish. Even though the bids in the two experiments are positively correlated, they clearly suggest that the individual preferences are...

Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized...

We use panel data from two experiments conducted five months a part to investigate the stability of individual preferences and aggregate demand for five types of fish. Even though the bids in the two experiments are positively correlated, they clearly suggest that the individual preferences are...

The demand for U.S. feed grain is estimated using a six-equation simultaneous model. Four different utilizations of feed grain and feed grain price as well as the number of animal units fed are estimated. The reduced form of the model is used to provide forecasts of the endogenous variables for...
