Economics faculty expect that students have an integrated understanding of economic theory upon graduation and that they grasp and appreciate how all elements of markets naturally move to equilibrium. Through assessment activities, the authors discovered that their students were not developing that knowledge, so they turned to learning theory to…

The authors use a relatively simple diagram accompanied by mathematical analysis to compare two pricing strategies: price-quantity packages and a two-part tariff. This is done both from the monopolist's point of view and from the welfare point of view. The authors show that in the case of two consumer types, the price-quantity packages strategy…

Reconsiders Uriel Spiegel's analysis of the Giffen phenomenon, a utility function that yields an inferior good with an upward-sloping demand curve. Extends this to include similar utility functions that yield inferiority. Discusses the earlier work of related theorists including Liebhafsky, Vandermeulen, and Wold and Jureen. (MJP)

Reexamines Spiegel's analysis of the Giffen phenomenon, a utility function that yields an inferior good with an upward-sloping demand curve and incorporates Christian Weber's criticism into the model. Disagrees with Weber on some points but agrees that as income decreases the likelihood of the Giffen product decreases. (MJP)
