uld not, however, represent general inflation in an overall economy. To measure overall inflation, the price change of a large 'basket' of representative goods and services is measured.

This theory begins with the equation:

M is the quantity of money.

V is the velocity of money in final expenditures;

P is the general price level;

Q is an index of the real value of final expenditures;

In this formula, the general price level is affected by the level of economic activity (Q), the quantity of money (M) and the velocity of money (V). The formula is an identity because the velocity of money (V) is defined to be the ratio of final expenditure () to the quantity of money (M).

a) Supply side economics

Supply-side economics is a school of macroeconomic thought that argues that economic growth can be most effectively created by lowering barriers for people to produce (supply) goods and services, such as adjusting income tax and capital gains tax rates, and by allowing greater flexibility by reducing regulation. Consumers will then benefit from a greater supply of goods and services at lower prices.

The term “supply-side economics” is used in two different but related ways. Some use the term to refer to the fact that production (supply) underlies consumption and living standards. In the long run, our income levels reflect our ability to produce goods and services that people value. Higher income levels and living standards cannot be achieved without expansion in output. Virtually all economists accept this proposition and therefore are “supply siders. Supply-side economics” is also used to describe how changes in marginal tax rates influence economic activity. Supply-side economists believe that high marginal tax rates strongly discourage income, output, and the efficiency of resource use. In recent years, this latter use of the term has become the more common of the two and is thus the focus of this article. The marginal tax rate is crucial because it affects the incentive to earn. The marginal tax rate reveals how much of one’s additional income must be turned over to the tax collector as well as how much is retained by the individual. For example, when the marginal rate is 40 percent, forty of every one hundred dollars of additional earnings must be paid in taxes, and the individual is permitted to keep only sixty dollars of his or her additional income. As marginal tax rates increase, people get to keep less of what they earn.

An increase in marginal tax rates adversely affects the output of an economy in two ways. First, the higher marginal rates reduce the payoff people derive from work and from other taxable productive activities. When people are prohibited from reaping much of what they sow, they will sow more sparingly. Thus, when marginal tax rates rise, some people those with working spouses, for example will opt out of the labor force. Others will decide to take more vacation time, retire earlier, or forgo overtime opportunities. Still others will decide to forgo promising but risky business opportunities. In some cases, high tax rates will even drive highly producti本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
