This chapter surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

Accommodative monetary policy during the financial crisis was instrumental in preventing a deeper recession. Views differ, however, on how long such measures should be kept in place. At the heart of this debate is the notion that a protracted period of policy accommodation could create...

Historically, periods of high indebtedness have been associated with a rising incidence of default or restructuring of public and private debts. A subtle type of debt restructuring takes the form of 'financial repression.' Financial repression includes directed lending to government by captive...

According to standard economic theory, fiscal policy should be counter-cyclical. In the neoclassical smoothing model of Barro (1979), a government should optimally run surpluses in good times and deficits in bad times. That is the same a government should do, though for different reasons, in the...

Recent literature has highlighted that international trade is mostly priced in a few key vehicle currencies, and is increasingly dominated by intermediate goods and global value chains (GVCs). Taking these features into account, this paper reexamines the business cycle dynamics of international...

This paper investigates the transmission channel of macroprudential instruments in a closed economy DSGE model with a rich set of financial frictions. Banks' decisions on risky retail loan concessions are based on borrowers' capacity to settle their debt with labor income. We also introduce...

We provide an introduction to optimal fiscal and monetary policy using the primal approach to optimal taxation. We use this approach to address how fiscal and monetary policy should be set over the long run and over the business cycle. We find four substantive lessons for policymaking: Capital...

There was a systemic failure of financial regulation: senior policymakers repeatedly enacted and implemented policies that destabilised the global financial system. They maintained these policies even as they learned of the consequences of their policies during the decade before the crisis. The...

We construct a new data set of quarterly international capital flows by sector, with an emphasis on debt flows. Using our new data set, we establish four facts. First, the co-movement of capital inflows and outflows is driven by inflows and outflows vis-à-vis the domestic banking sector....
