The paper presents empirical findings regarding the economic policy consequences of constitutional arrangements, in three different dimensions. First, the data are consistent with several theoretical predictions about the consequences of electoral rules and forms of government for fiscal policy...

This paper 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...

We show that even when the exchange rate cannot be devalued, a small set of conventional fiscal instruments can robustly replicate the real allocations attained under a nominal exchange rate devaluation in a dynamic New Keynesian open economy environment. We perform the analysis under...

Observed fiscal policy varies greatly across time and countries. How can we explain this variation across time and countries? This paper surveys the recent literature that has tried to answer this question. We adopt a unified approach in portraying public policy as the equilibrium outcome of an...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

This paper demonstrates how time consistency of the Ramsey policy - the optimal fiscal and monetary policy under commitment - can be achieved. Each government should leave its successor with a unique maturity structure for the nominal and indexed debt, such that the marginal benefit of a...

We present a theoretical model of a parliamentary democracy, where party structures, government coalitions and fiscal policies are endogenously determined. The model predicts that, relative to proportional elections, majoritarian elections reduce government spending because they reduce party...

The internal market in Europe will greatly increase the international mobility of resources. How will this affect fiscal policy in different countries? The first part of the paper considers taxation of capital in a two country model, where a democratically chosen government in each country...

We characterize fiscal and monetary policy in a monetary union with the potential for rollover crises in sovereign debt markets. Member-country fiscal authorities lack commitment to repay their debt and choose fiscal policy independently. A common monetary authority chooses inflation for the...

The global economy has a chronic shortage of safe assets which lies behind many recent macroeconomic imbalances. This paper provides a simple model of the Safe Asset Mechanism (SAM), its recessionary safety traps, and its policy antidotes. Safety traps share many common features with...
