The aim of the course is to present many of the decision problems managers face and to present the economic analysis they need to guide these decisions. In the first half of the course, microeconomic tools are used to structure complicated decision problems about production, pricing, investment, and other strategic issues, address uncertainty through probabilistic forecasts and sequential decisions. An additional goal is to distinguish different market structures and apply competitive strategies using game theory. In the second half, the focus shifts to the study of the national and global economic environments within which companies operate. We identify the drivers of fluctuations in GDP, inflation, interest and exchange rates, and other key features of the economies. Since governments play key roles in determining the fate of economies and companies, the final theme is the rationale for and efficacy of government policy tools.
