A new theory of price determination suggests that if primary surpluses are independent of the level of debt, the price level has to jump' to assure fiscal solvency. In this regime (which we call Fiscal Dominant), monetary policy has to work through seignorage to control the price level. If on...

Fifty years ago, the Chicago School argued that flexible exchange rates would insulate employment from foreign economic disturbances: there is no need for policy coordination; flexible exchange rates suffice. Twenty five years later, the Bretton Woods system was gone, and the first generation of...

What are the macroeconomic consequences of the dominant role of the dollar in the international monetary system? Here, we present a calibrated two country model in which exports are invoiced in the key currency, and government bonds denominated in the key currency are held internationally to...

Formation of the Euro area raises new questions about the coordination of monetary and fiscal policy. Using a New Neoclassical Synthesis (NNS) model, we show that a common monetary policy, responding to area-wide aggregates, has asymmetric effects on countries within the union, depending on...

Woodford (2003) describes a popular class of neo-Wicksellian models in which monetary policy is characterized by an interest-rate rule, and the money market and financial institutions are typically not even modeled. Critics contend that these models are incomplete and unsuitable for...

We calculate the welfare cost of nominal inertia in a New Neoclassical Synthesis model with wage and price stickiness, capital formation, and empirically estimated rules for government spending and the cental bank's interest rate policy. We calibrate our model to U.S. data, and we show that it...

The Balassa-Samuelson model, which explains real exchange rate movements in terms of sectoral productivities, rests on two components. First, for a class of technologies including Cobb-Douglas, the model implies that the relative price of nontraded goods in each country should reflect the...
