Computer programs written in BASIC for the study of microeconomic analysis with special emphasis in economic decisions on price, output, and profit of a business firm are described. A very brief overview of the content of each of the 28 computer programs comprising the course is provided; four of the programs are then discussed in greater detail. The first program discussed illustrates a demand function. The program is presented in a simple manner so that even students who have never touched a computer terminal can easily learn to use the computer and run the program. The second computer program described deals with the interaction of demand and supply and the effect of change in demand and/or supply upon equilibrium price and resource allocation. The third program deals with the derivation of a consumer's demand schedule by the utility indifference curve approach. The purpose of the fourth computer program described is to bring together both the sales and production functions into one unified general program for making economic decisions on price and output for profit, break-even, and shut-down conditions in the short run. For each program there are charts outlining program commands and sample printouts. (RM)
