Abstract

Business cycles are an essential part of macroeconomics. However, the study of macroeconomics often ignores the observed business cycles. During and after the global financial crisis, several economists have emphasized that macroeconomics courses will have to be changed. This paper presents a real world application of the IS-TR model, which helps to explain and teach business cycles. The simple Keynesian model clearly explains output fluctuations and the conduct of monetary policy. The main reason for strong business cycles in the euro area has been shocks in the goods market. The European Central Bank has changed its main interest rate mainly as a reaction to changes in the output gap.
