Whenever we visit a foreign country and observe the standard of living over there compared to our local statistics, we often bump into questions like: Why is the average income high in some countries while it is low compared to others or ours? Why do prices sometimes rise rapidly while at other times they are relatively stable? Why do employment and production expand in some years and contract in others? These questions carry elements regarding the subject macroeconomics since they look into the workings of the entire economy. In the case between countries, the general economy is seen as a collection of interacting households and firms in various existing markets.
