Step-by-step explanation:
A trade off is a situation where an economic agent has to decide between two options he wants. This is a concept widely used in economic theory, for example when the government will use monetary policy. If monetary policy is expansionary, it may increase the employment rate but cause inflation. If the government pursues a contractionary monetary policy, it may lower inflation but increase the unemployment rate. Then there is a trade-off in the government's choice between inflation and unemployment. Monetary policy will then be administered according to the choice the government makes.
