CEVAP:

Contrary to microeconomics, in macroeconomics, we think big. We consider, in macroeconomics, not only the supply of and demand for bread in a particular
market, but the supply of and demand for all goods and services produced in the economy; not only the price of bread but the average price of all products in the economy; not only the consumption of a single person or family, but the overall consumption of all the people or families in the economy; not only the investment of a single automobile factory, but investments of all businesses in the economy as a whole. Macroeconomics is not only interested in the determinants of these large scale variables, but also mutual relationships among them and the meaning of changes they display in time. In other words, macroeconomic analysis deals with how macro variables of a national economy affect each other and how they are determined when the economy tends to achieve equilibrium.
