Why is it so important when the nominal policy interest rate is at the Zero Lower Bound to maintain a positive expected rate of​ inflation?

A low or negative expected rate of inflation results in an increase in real borrowing costs when the risk premium goes up. AND A positive expected rate of inflation allows the central bank to keep real borrowing costs relatively low when the risk premium rises. AND A positive expected rate of inflation enables the central bank to significantly offset any increase in the risk premium. D. ALL OF THE ABOVE

Consider the job of a delivery person and a computer network administrator. In which of these jobs does a worker have more bargaining​ power?

Given the answers above and the material in the​ text, why might recapitalization be a better policy than buying the troubled​ assets?

Buying trouble assets will at best provide a bank liquidity but not necessarily positive capital. AND Unless the government is willing to buy assets at above market​ prices, buying assets does not mean bank capital will remain positive. AND The direct infusion of capital improves the solvency of the bank. ALL OF THE ABOVE

Differences in both m and z can explain variation across countries and across time.

Nominal and real interest rates around the world There are a few episodesLOADING... of negative nominal interest rates around the world. Some may or may not be in play as you read this book. The Swiss nominal policy​ rate, the Swiss equivalent of the federal funds​ rate, was negative from 2014 and 2018. If​ so, why not hold cash instead of​ bonds?

Even with negative​ yields, bonds allow investors to achieve some degree of portfolio diversification. AND Bonds with negative yields will still be profitable to hold if bond yields are expected to decrease even further. AND Foreign​ investors, particularly those from struggling emerging market​ economies, may be willing to​ "pay for​ safety." ALL OF THE ABOVE

Consider the following​ statement: The Phillips curve implies that when unemployment is​ high, inflation is​ low, and vice versa.​ Therefore, we may experience either high inflation or high​ unemployment, but we will never experience both together. Is this statement​ true, false, or​ uncertain? Choose the answer that best explains.

False. If inflation expectations are​ high, it is possible to have high inflation and high unemployment simultaneously.

Consider the following​ statement: As long as we do not mind having high​ inflation, we can achieve as low a level of unemployment as we want. All we have to do is increase the demand for goods and services by​ using, for​ example, expansionary fiscal policy. Is this statement​ true, false, or​ uncertain? Choose the answer that best explains.

False. This would require not merely high inflation but​ ever-increasing inflation because expectations adjust.
