Managerial Economics and Business Analysis 専門講座

All goods and services are subject to scarcity at some level. Scarcity means that society must develop some allocation mechanism – rules to determine who gets what. Over recorded history, these allocation rules were usually command based – the king or the emperor would decide. In contemporary times, most countries have turned to market based allocation systems. In markets, prices act as rationing devices, encouraging or discouraging production and encouraging or discouraging consumption in such a way as to find an equilibrium allocation of resources. We will construct demand curves to capture consumer behavior and supply curves to capture producer behavior. The resulting equilibrium price “rations” the scarce commodity. Markets are frequent targets of government intervention. This intervention can be direct control of prices or it could be indirect price pressure through the imposition of taxes or subsidies. Both forms of intervention are impacted by elasticity of demand. After this course, you will be able to: • Describe consumer behavior as captured by the demand curve. • Describe producer behavior as captured by the supply curve. • Explain equilibrium in a market. • Explain the impact of taxes and price controls on market equilibrium. • Explain elasticity of demand. • Describe cost theory and how firms optimize given the constraints of their own costs and an exogenously given price.

In this class, we will derive equilibrium outcomes across a variety of market structures. We will begin by understanding equilibrium under a market structure called Perfect Competition, a benchmark construction. Economists have tools to measure the efficiency of market outcomes. We next consider the polar extreme of a competitive market: a monopoly market. We will determine the monopoly equilibrium price and quantity and efficiency properties. Much economic activity takes place in markets with just a handful of very large producers. To understand equilibrium in these oligopoly markets requires more careful attention to strategic interdependence. To capture this interdependence, we consider collusive arrangements among a small number of rivals as well as the use of simple game theoretic techniques to model equilibrium. Market Failure describes situations where markets fail to find the efficient outcome. Information asymmetries are one fertile form of market failure. Another form of market failure occurs when externalities are present. We will examine one key externality, pollution, and construct a policy prescription to mitigate the negative efficiency impacts of this externality. Upon successful completion of this course, you will be able to: • Explain how different market structures result in different resource allocations. • Model the impact of external shocks to a particular market structure and demonstrate the new equilibrium price and quantity after the impact of this external shock has played out. • Evaluate the efficiency of an equilibrium. Different market structures produce different levels of efficiency. • Explain when and why the government might intervene with regulatory authority or antitrust litigation to lessen inefficiencies in some markets. • Describe how information problems can cause inefficient outcomes. • Understand externalities and consider optimal government response to these market failures.

This course discusses how macroeconomic variables affect individuals’ personal, professional, and public activities and lays the foundation for the analysis of the mechanisms that drive macroeconomic variables. It start in its first module by introducing the key macroeconomic variables and explaining how they are defined and measured in order to enable the students to interpret macroeconomic data properly. In the second module, the course offers a perspective for separating out various parts of the economy driven by different processes and for combining those components to develop a richer view of the whole. In particular, it applies this approach to the analysis of the relationship of the trade deficit with the budget deficit and private savings, offering insights about some key determinants of the balance of payments. The third and fourth modules focus on the analyses of the foreign currency and money markets to provide fundamental models of the interest rate and exchange rate determination. They also discuss how these variables interact with each other and with the macroeconomic conditions, particularly monetary policy and the expectations about the future trends in the economy. These analyses lay the foundation for more comprehensive models of the macroeconomy in the next course of the Managerial Economics and Business Analysis Specialization. At the end of this course, you will be able to: • Systematically assess the national and international economic environment in which you live and work. • Analyze macroeconomic issues using key tools. • Be a more effective professional in your line of activity.

This course examines macroeconomic performance in the short run and the long run based on the economy’s institutional and policy environment. The first module develops a model of macroeconomy in the short run when the price level has its own momentum and does not respond much to supply and demand forces. The model enables one to see how GDP, interest rate, and exchange rate are determined in the short run and how they respond to macroeconomic shocks and policies. The second module starts the analysis of long-run equilibrium by examining the foreign exchange market. It then connects the long-run outcome with expectations about the future trends in the exchange rate at each moment, which constitute a key driver of the spot exchange rate in the short run. The methodology developed for this purpose can be applied to expectations concerning other macroeconomic variables as well. Finally, the long-run foreign exchange model is employed to derive a number of important lessons for the long run trends in currency values and competitiveness of producers in various countries. The third module examines the drivers of aggregate output in the long run and the mechanisms of adjustment from the short run to the long run. The model provides insights about why some countries are much richer than others and why some economies grow faster than others over decades. The analysis also sheds light on why inflation varies across countries or over time in the same country. The model is employed to analyze the sources of macroeconomic instability and the roles of fiscal and monetary policies in stabilization or destabilization of the macroeconomy. The final module discusses the characteristics of desirable macroeconomic policies and the reasons why actual policies deviate from them. It connects these deviations to country characteristics that one needs to take into account when assessing a country’s long-term macroeconomic environment. The module ends with a discussion of the institutional conditions that help bring about better fiscal and monetary policies. At the end of this course, you will be able to: • Understand how the market for aggregate goods and services interacts with the money market to shape the macroeconomic equilibrium that determines income, interest rate, and exchange rate in the short run. • Understand the links between the short-run and long-run processes. • Assess the dynamic effects of macroeconomic policies and understand the roles of globalization, government policies, institutions, and expectations in macroeconomic outcomes.
