Q: Suppose inflation is determined as in Section 12.8. Suppose

Suppose inflation is determined as in Section 12.8. Suppose the government is able to reduce the costs of inflation; that is, suppose it reduces the parameter a in equation (12.64). Is society made be...

Q: Suppose a policymaker is in office for two periods. Output is

Suppose a policymaker is in office for two periods. Output is given by (12.63) each period. There are two possible types of policymaker, type 1 and type 2. A type-1 policymaker, which occurs with prob...

Q: Suppose that output is given by y = yn +b(

Suppose that output is given by y = yn +b(π − πe), and that the social welfare function is γy−aπ2/2, where γ is a random variable with mean γ and variance σ2 γ . πe is determined before γ is observed;...

Q: Consider a discrete-time version of the analysis of money growth

Consider a discrete-time version of the analysis of money growth, inflation, and real balances in Section 12.1. Suppose that money demand is given by mt − pt = c−b(Etpt+1 − pt), where m and p are the...

Q: Consider a discrete-time model where prices are completely unresponsive to

Consider a discrete-time model where prices are completely unresponsive to unanticipated monetary shocks for one period and completely flexible thereafter. Suppose the IS equation is y = c −ar and tha...

Q: Assume, as in Problem 12.2, that prices are

Assume, as in Problem 12.2, that prices are completely unresponsive to unanticipated monetary shocks for one period and completely flexible thereafter. Assume also that y= c −ar and m − p = b +hy−ki h...

Q: Consider the Tabellini Alesina model in the case where α can only

Consider the Tabellini Alesina model in the case where α can only take on the values 0 and 1. Suppose that the amount of debt to be issued, D, is determined before the preferences of the period-1 medi...

Q: Consider the Tabellini Alesina model in the case where α can only

Consider the Tabellini Alesina model in the case where α can only take on the values 0 and 1. Suppose, however, that there are 3 periods. The period-1 median voter sets policy in periods 1 and 2, but...
