Microeconomics is the branch of economics which caters with individual firms, consumers, and industries as they produce, buy and sell goods and services. Macroeconomics, on the other hand, deals with changes in the overall level of economic activity, interest rates, unemployment, and exchange rates to affect the competitive strategies of individual firms and industries. It caters to the behavior of individuals aggregated into different sectors in the economy.

The market price is determined by the supply of all producers and consumers who purchase the goods. Therefore, an individual producer will sell any amount of product at the market determined price and will not be able to intelligence its price by selling more at a lesser price. Thus, economists characterize a perfectly competitive firm as a price-taker. The pricing behavior of other firms differ from perfectly competitive firms for they have some degree of market power or the ability to influence their prices and develop other competitive strategies that allow them to earn large profits over longer period of time.

SQ. In macroeconomics, what are the five major categories of spending that make up GAP? Are all five categories added together to determine GAP? Following are the five categories of spending that make up GAP: 1 . C = Personal expenditures by all households on durable goods, nondurable goods and services 2. I = Gross private domestic investment spending on nonresidential structures, equipment, software, residential structures and inventories. 3. G = Government consumption expenditures and gross investment 4. X = Total export spending 5. M ?Total import spending

All these categories are not added to determine GAP. M is subtracted from X to get F (net export spending) which is added to C, l, and G to derive GAP. GAP=C+I+G+(X-M) SQ.
