　　 A-Level经济学问答题详解

　　  Deflation and Disinflation

　　Deflation（通货紧缩）与 disinflation（通货膨胀减缓）经常在A-Level考试中出现，两者的区别如下，小伙伴们认真阅读哦 !

　　Deflation is a persistent fall in the average price level in the economy.

　　Disinflation is a falling rate of inflation.

　　通货紧缩是经济体中价格水平持续下降的情况，通货膨胀减缓是通货膨胀率下降。两者的本质区别，Deflation（通货紧缩）是指价格水平下降，disinflation（通货膨胀减缓）是指价格水平还在上涨，只是涨幅变小。

　　对经济体整体而言，价格下降是好情况吗？未必，通货紧缩的影响如下：

　　Consequences of Deflation

　　 　A: Falling consumption: Consumers delay purchases as they expect further price reductions. AD shrinks even more, pushing even lower the average price level.

　　B: Reducing investment: As demand is low, firms are forced to cut prices, to cut down costs & even to reduce their scale of production. Low business confidence will also discourage investment.

C: Rising bankruptcies: Firms’ profits decline. As a result, dividends & investment returns fall and so share prices also fall. Business insolvencies will increase.

　　D: Rising unemployment: Since demand is low & prices are falling, firms will lay off workers and/or reduce wages. Unemployment will rise & this will further discourage consumption.

E: vicious cycle of falling prices/falling AD e.g. “lost decade” in Japan

       F: reduced effectiveness of monetary & fiscal policyas interest rates cannot fall below zero & households prefer to save/postpone spending

G: banking system at risk as loans are not repaid

H: negative multiplier effect

I: government debt expands in real terms

　　 3) 真题答案：

　　Inflation is a sustained rise in the general price level. Deflation is a sustained fall in the general price level or a reduction in aggregate economic activity. Inflation has effects on international competitiveness, shoe leather and menu costs, the distribution of income, the ability to plan and the level of confidence. Deflation is linked to rising unemployment, falling economic growth, lower living standards, changing international competitiveness, changing distribution of income(differently to inflation) and loss of confidence. There is some overlap between the effects, and the effects may depend upon the rate of change. Mild inflation is often thought to be desirable. Governments may favour inflation as it reduces the real value of debt and increase income though higher tax revenue. The desirability will depend on the standpoint adopted.
