Course Description: Principles of Microeconomics At the foundation of economics is the concept of foregone opportunity: by doing this, I forego that. Hence the course opens with the study of scarcity, opportunity cost, and comparative advantage. The body of the course is divided into three components. In the first third of the course, we will analyze the determinants of trade in markets using the concepts of demand, supply, and equilibrium. In particular, we will learn how prices and the amount traded depend on the incomes of consumers, the prices of other goods (complements and substitutes), the prices of inputs used to produce the good, technology, and government restrictions (e.g., rent controls, prohibition, taxes, and subsidies). In the middle third of the course, we will develop a deeper understanding of the determinants of demand and supply. In particular, we will analyze the fundamentals of production and costs, derive market supply curves based on the profit-maximizing choices of individual firms, explore the dynamics of how markets respond to fundamental changes (e.g., innovation), and characterize the effects of monopoly power. This section of the course closes by applying game theory to the stategic interactions or rivalries among firms. The final third of the course focuses on the markets for resources or inputs, such as flour, cheese, and restaurant space in the case of pizza production. We will investigate what determines whether a resource is paid what it's worth. In particular, are workers paid what they're worth in a free market? We will also study financial markets, including determination of equilibrium interest rates and iinvestments. The course closes with a characterization of the performance of free markets in the presence of externalities: what happens in free markets when one person's choices spill over to directly effect the welfare of others.
