Describes the use of Mathcad, an interactive software package that responds to mathematical input, in an undergraduate economics class. Mathcad uses a rules-based programming language that "reads" the relationships among variables and constraints defined by the user, solves for unknowns, and graphs for one or more equations. (MJP)

Describes a computer software program that allows students, working independently and interactively with the computer, to select alternative market conditions and/or policies and view the results numerically as well as graphically. Discusses options and models provided by the software as well as classroom applications. (MJP)

Maintains that computer-assisted instruction built around a spreadsheet-based model can illustrate and simplify some of the more difficult concepts concerning economics and fisheries. Describes a software program that illustrates overcapitalization, asset fixity, resource rent capture, economic optimum, and sustainable yield. (MJP)

Describes a computer software program where students define alternative policy sets and compare their effects on the welfare of consumers, producers, and the public sector. Policy sets may be a single tax or quota or a mix of taxes, subsidies, and/or price supports implemented in the marketing chain. (MJP)
