In some ways all cities are alike; in some ways every one is different. Economics can help one understand both the common features and the differences. Topics may include the following: examples of the diversity of economic bases that generate employment, including heavy and light industry, "high tech," defense, tourism and amenities, government, and finance; racial and class segregation, land markets and transportation links, and how they shape patterns of land use, rents, density, building height, and household income; dependence and competition between downtowns and suburbs; "edge cities"; problems of declining small cities and towns and the "WalMart Problem." One or more of the short papers that each student writes may apply the principles of the course to a particular city of his/her choice. Students will have the opportunity to use computer mapping of urban conditions in one of their papers. Each student will meet with the instructor and one other student on a weekly basis. Students will be expected to prepare a 6- to 8-page paper every other week and act as a discussant/critiquer for the other student's paper on the "off" weeks. The tutorial will meet a few times as a whole. Students' grades will be based on their contributions to the tutorial and the quality of their papers. Prerequisite: Economics 101.
