What is the relationship between large deficits and inflation in industrialized countries?
Examining industrialized countries, the authors find that large deficits are not associated with higher inflation contemporaneously, nor are they associated with the emergence of higher inflation in subsequent years. This finding suggests that countries that can afford large deficits have built solid reputations and institutions supporting a sound monetary policy and the reversion to a stable fiscal regime.
Working Paper
Tax riots
This paper considers an optimal taxation environment where household income is private information, and the government randomly audits and punishes households found to be underreporting. We prove that the optimal mechanism derived using standard mechanism design techniques has a bad equilibrium (a tax riot) where households underreport their incomes, precisely because other households are expected to do so as well. We then consider three alternative approaches to designing a tax scheme when one is worried about bad equilibria.

Fiscal policy and price stability: the case of Italy, 1992–98
Many authorities at home and abroad questioned Italy's ability to meet the strict criteria to join the European Monetary Union. The author looks at the interaction between fiscal policy and monetary policy in Italy between 1992, when it exited the European Exchange Rate Mechanism, and 1998, when an official announcement was made that it would join the union.

Equilibrium and government commitment
How should a government use the power to commit to ensure a desirable equilibrium outcome? In this paper, I show a misleading aspect of what has become a standard approach to this question, and I propose an alternative. I show that the complete description of an optimal (indeed, of any) policy scheme requires outlining the consequences of paths that are often neglected. The specification of policy along those paths is crucial in determining which schemes implement a unique equilibrium and which ones leave room for multiple equilibria that depend on the expectations of the private sector.

A Ramsey Theory of Financial Distortions
The interest rate on government debt is significantly lower than the rates of return on other assets. From the perspective of standard models of optimal taxation, this empirical fact is puzzling: typically, the government should finance expenditures either through contingent taxes, or by previously-issued state-contingent debt, or by labor taxes, with only minor effects arising from intertemporal distortions on interest rates. We study how this answer changes in an economy with financial frictions, where the government cannot directly redistribute towards the agents in need of liquidity, but ...

Fiscal consequences of paying interest on reserves
We review the role of the central bank's (CB) balance sheet in a textbook monetary model, and explore what changes if the central bank is allowed to pay interest on its liabilities. When the central bank cannot pay interest, away from the zero lower bound its (real) balance sheet is limited by the demand for money. Furthermore, if securities are not marked to market and the central bank holds its bonds to maturity, it is impossible for the central bank to make losses, and it always obtains profits from being a monopoly provider of money. When the option of paying interest on liabilities is ...

Public investment and budget rules for state vs. local governments
Across different layers of the U.S. government there are surprisingly large differences in institutional provisions that impose fiscal discipline, such as constitutionally mandated deficit or debt limits, or specific tax bases. In this paper we develop a framework that can be used to quantitatively assess their costs and benefits. The model features both endogenous and exogenous mobility across jurisdictions, so we can evaluate whether the different degree of mobility at the local vs. national level can justify different institutional restrictions. In preliminary results, we show that pure ...

A Ramsey Theory of Financial Distortions
The return on government debt is lower than that of asset with similar payoffs. We study optimal debt management and taxation when the government cannot directly redistribute towards the agents in need of liquidity but otherwise has access to a complete set of linear tax instruments. Optimal government debt provision calls for gradually closing the wedge between the returns as much as possible, but tax policy may work as a countervailing force: as long as financial frictions bind, it can be optimal to tax capital even if this magnifies the discrepancy in returns.

Credit crunches and credit allocation in a model of entrepreneurship
We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business in this set-up, we show that, by reducing entrepreneurial firm size and earnings, negative shocks have a very persistent effect on real activity. In determining the speed of recovery from an adverse economic shock, the most important factor is the extent to which the shock erodes entrepreneurial wealth.

On the relationship between mobility, population growth, and capital spending in the United States
In this paper, we assess the empirical relationship between population growth, mobility, and state-level capital spending in the United States. To evaluate the magnitude of the coefficients, we introduce an explicit, quantitative political-economy model of government spending determination, where mobility and population growth generate departures from Ricardian equivalence. Our estimates find strong responses in the level of capital provision per capita to these demographic movements; in fact, the resulting coefficients are stronger than the model delivers. Regression coefficients on ...
