Signs of a Recession
Home foreclosures were just one of the many signs and symptoms of the recent Great Recession. During that time, many businesses closed and many people lost their jobs. (Credit: modification of work by Taber Andrew Bain/Flickr Creative Commons)

We have learned that the level of economic activity, for example output, employment, and spending, tends to grow over time. In The Keynesian Perspective we learned the reasons for this trend. The Macroeconomic Perspective pointed out that the economy tends to cycle around the long-run trend. In other words, the economy does not always grow at its average growth rate. Sometimes economic activity grows at the trend rate, sometimes it grows more than the trend, sometimes it grows less than the trend, and sometimes it actually declines. You can see this cyclical behavior in [link].

U.S. Gross Domestic Product, Percent Changes 1930–2012
The chart tracks the percent change in GDP since 1930. The magnitude of both recessions and peaks was quite large between 1930 and 1945. (Source: Bureau of Economic Analysis, “National Economic Accounts”)

This empirical reality raises two important questions: How can we explain the cycles, and to what extent can they be moderated? This chapter (on the Keynesian perspective) and The Neoclassical Perspective explore those questions from two different points of view, building on what we learned in The Aggregate Demand/Aggregate Supply Model.
