( Chapter Overview

Chapter 1 begins by introducing a set of three central macroeconomic concepts, called the “Big Three Concepts of Macroeconomics. They are the unemployment rate, the inflation rate, and productivity growth. Introducing the field of macroeconomics to students in this way has an important advantage. It facilitates the early introduction and definition of basic macroeconomic terminology, which gives students a chance to get used to thinking of macroeconomic issues in terms of these concepts.

A brief section describes the differences between macroeconomics and microeconomics and discusses the role of theory. The purpose of theory is to simplify complex economic relationships so that one can perform meaningful analysis of economic issues. Theories need not model accurately all aspects of the economic environment and behavior to have predictive power and

LYNCH Office: Rawls 4039 Phone 494-4388 lynch@purdue.edu Secretary: Sherry Fisher 496-7227 Office Hours: Monday and Wednesday 3:00-4:00 and by appointment Introduction to the topic: As recent turmoil in the financial markets has demonstrated, macroeconomic fluctuations in the economy can create a difficult operating environment for the firm. This situation is further complicated by the fact that it is an environment over which the firm has little control. Even though the firm cannot control the environment, it can still react to economic conditions in ways that minimize its uncertainty as long as it understands the constraints it is facing. The purpose of this course is to help in an understanding of the macroeconomy. Macroeconomics is that branch of economics that seeks to understand and explain changes in output, general prices, employment, interest rates, foreign exchange rates, the balance of payments, and other related phenomena. Emphasis is given in this course to analyzing financial markets where interest rates are determined. We will spend more time than usual on the financial markets this year in response to the uncertainty in that environment today. Also, since the macroeconomic environment in this country is increasingly influenced by international conditions, the factors underlying trade and exchange...

...Economics 2102 Intermediate Macroeconomics George Washington University Fall 2014 Professor Henry S. Terrell, Ph.D. Course Description Economics 2102 is a course in Intermediate Macroeconomics. The course will analyze the economy in a “general equilibrium” framework, where the performance of the economy in terms of output, employment and unemployment, inflation, and international trade and capital flows is determined by the simultaneous interaction of the goods, labor, money, and international markets. The course will highlight the differences between the economy in the short and long run, the important role that expectations about the future play in macroeconomic analysis, the role, limits, and transmission mechanisms of fiscal and monetary policy in efforts at economic stabilization, and the Solow model of the determinants of long-term economic growth and the role of capital formation in economic growth. The course will also explicitly consider the current challenges to the economy. Textbook and Other Materials The textbook is MacroEconomics, by Andrew B. Abel, Ben S. Bernanke, and Dean Croushore, 8th edition. The MyEconLab system that comes with that textbook is required. Grades will be based on: 1.
