- Abstract
- In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate fluctuations. The main result of the paper is that price stability appears to be a central goal of optimal monetary policy. The optimal rate of inflation under an income tax regime is half a percent per year with a volatility of 1.1 percent. This result is surprising given that the model features a number of frictions that in isolation would call for a volatile rate of inflation-particularly nonstate-contingent nominal public debt, no lump-sum taxes, and sticky wages. Under an income-tax regime, the optimal income tax rate is quite stable, with a mean of 30 percent and a standard deviation of 1.1 percent.

- Abstract
- This paper studies the role of asset-market completeness for the properties of optimal fiscal and monetary policy. A suitable framework for this purpose is the small open economy with complete international asset markets. For in this environment changes in policy represent country-specific risk diversifiable in world markets. Our main finding is that the fundamental public finance principle whereby when taxes on all final goods are available, it is optimal to tax final goods uniformly fails to obtain. In general, uniform taxation is optimal because it amounts to a non-distorting tax on fixed factors of production. In the open economy this principle fails because when households can insure against the risk of a policy reform, initial private asset holdings are contingent on actual policy and thus no longer represent an inelastically supplied source of income. Furthermore optimal consumption and income taxes do not respond to government purchases shocks and the Friedman rule is optimal only if the Ramsey planner has access to consumption taxes.

- Abstract
- This paper presents a fiscal theory of sovereign risk and default. Under certain monetary-fiscal regimes, the risk of default, and thus the emergence of sovereign risk premia, are inevitable. The paper characterizes the equilibrium processes of the sovereign risk premium and the default rate under a number of alternative monetary policy arrangements. It is argued that, given the fiscal stance, monetary policy plays a crucial role in shaping the equilibrium behaviour of the country risk premium and the default rate. For instance, under some of the monetary policy rules considered, the expected default rate and the sovereign risk premium are zero (and therefore unforecastable) although the government defaults regularly. Under other monetary regimes the default rate and the sovereign risk premium are serially correlated (and therefore forecastable). In addition, environments are characterized under which delaying default is counterproductive.
