Each approach, Keynesian and neoclassical, has its strengths and weaknesses. The short-term Keynesian model, built on the importance of aggregate demand as a cause of business cycles and a degree of wage and price rigidity, does a sound job of explaining many recessions and why cyclical unemployment rises and falls.
By focusing on the short-run adjustments of aggregate demand, Keynesian economics risks overlooking the long-term causes of economic growth or the natural rate of unemployment that exists even when the economy is producing at potential GDP. The neoclassical model, with its emphasis on aggregate supply, focuses on the underlying determinants of output and employment in markets, and thus tends to put more emphasis on economic growth and how labor markets work. However, the neoclassical view is not especially helpful in explaining why unemployment moves up and down over short time horizons of a few years.
Nor is the neoclassical model especially helpful when the economy is mired in an especially deep and long-lasting recession, like the Great Depression of the s. Keynesian economics tends to view inflation as a price that might sometimes be paid for lower unemployment; neoclassical economics tends to view inflation as a cost that offers no offsetting gains in terms of lower unemployment.
Macroeconomics cannot, however, be summed up as an argument between one group of economists who are pure Keynesians and another group who are pure neoclassicists. Instead, many mainstream economists believe both the Keynesian and neoclassical perspectives. Robert Solow , the Nobel laureate in economics in , described the dual approach in this way:.
Many modern macroeconomists spend considerable time and energy trying to construct models that blend the most attractive aspects of the Keynesian and neoclassical approaches.
Neo-Keynesian Economics: An Overview Classical economic theory presumed that if demand for a commodity or service was raised, then prices would rise correspondingly and companies would increase output to meet public demand. Key Takeaways Keynesian theory does not see the market as being able to naturally restore itself. Neo-Keynesian theory focuses on economic growth and stability rather than full employment. Neo-Keynesian theory identifies the market as not self-regulating. The two major areas of microeconomics by Neo-Keynesians are price rigidity and wage rigidity.

I would have loved to have the certificate but for pausity of funds.
Really well presented, yes it was somewhat of a challenge in getting my head around some of the difference approaches. Certainly a must for any MP or political activist. This course was simply perfect. I thoroughly enjoyed the content I learned throughout the course, as well as its structure i. Overall expanded my knowledge in a field I have a high interest in, and would highly recommend this course.
It provided me with great insights about Politcal Economy. I think some specific topics such as unemployment and inflation can be discussed further more. I hope more courses about macroeconomics can be set up in the future. Category: FutureLearn Local. Category: FutureLearn Local , Learning.

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 Figure 2. Figure 2. Gross Domestic Product, Percent Changes — The chart tracks the percent change in GDP since The magnitude of both recessions and peaks was quite large between and This empirical reality raises two important questions: how can we explain the cycles, and to what extent can they be moderated?
To answer those questions, we turn to the Keynesian and neoclassical perspectives.
