Because we interact, cooperate, and compete with each other in the economy, economics is a social subject. Everyone experiences the economy. Everyone contributes to it, one way or another. Everyone has an interest in the economy: in how it functions, how well it functions, and in whose interests it functions. This course aims to motivate students to learn economics by asking questions about how the contemporary economy functions as an overall system. The course focuses on competition between firms; the determination of overall investment, consumption and employment; and the relationship between the economy and the natural environment.
