View answer resolution
【Answer to question 1】A

【analysis】

A is correct. As suggested particularly by the earliest RBC models, a person is unemployed because he or she is asking for wages that are too high. 

B is incorrect. RBC models of the business cycle conclude that expansions and contractions represent efficient operation of the economy in response to external real shocks. Because the level of economic activity at any time is consistent with maximizing expected utility, the policy recommendation of RBC theory is for government not to intervene in the economy with discretionary fiscal and monetary policy.

 C is incorrect. The initial New Classical models did not include money; they were called real business cycle models (often abbreviated as RBC). Cycles have real causes, such as changes in technology, whereas monetary variables, such as inflation, are assumed to have no effect on GDP and unemployment.

【Answer to question 2】A

【analysis】

A is correct. Average weekly initial claims for unemployment insurance is a leading indicator of economic activity, and a decrease in it is an indication of rehiring at the start of a recovery.

 B is incorrect. A decrease in average weekly initial claims for unemployment is a positive leading indicator, indicating that an upturn is coming, not that a peak has been hit. 

C is incorrect. A decrease in average weekly initial claims for unemployment is a positive leading indicator, indicating that an upturn is coming, not a downturn.

成功=时间+方法,自制力是这个等式的保障。世上无天才,高手都是来自刻苦的练习。而人们经常只看到“牛人”闪耀的成绩,其成绩背后无比寂寞的勤奋。小编相信,每天都在勤奋练习,即使是一点点的进步,大家一定可以成为人人称赞的“牛人”。
