Elections and Macroeconomic Policy Cycles

Review of Economic Studies 1988 55(1), 1 open access
There is an extensive empirical literature on political business cycles, but its theoretical foundations are grounded in pre-rational expectations macroeconomic theory. Here we show that electoral cycles in taxes, government spending and money growth can be modeled as an equilibrium signaling process. The cycle is driven by temporary information asymmetries which can arise if, for example, the government has more current information on its performance in providing for national defence. Incumbents cheat least when their private information is either extremely favourable or extremely unfavourable. An exogeneous increase in the incumbent party's popularity does not necessarily imply a damped policy cycle.

A Constant Recontracting Model of Sovereign Debt

Journal of Political Economy 1989 97(1), 155-178 open access
Few sovereign debtors have repudiated their obligations entirely. But despite the significant sanctions at the disposal of lenders, many borrowers have been able to consistently negotiate for reduced repayments. This paper presents a model of the on-going bargaining process that determines repayment levels.

The Information Content of the Interest Rate and Optimal Monetary Policy

Quarterly Journal of Economics 1983 98(4), 545 open access
Optimal monetary policy rules are derived in a rational expectations cum contracting framework. Monetary policy is redundant if wage setters exploit the incomplete current information embodied in today's nominal interest rate. However, the monetary authorities can save wage setters the costs of “indexing†to the interest rate. A contemporaneous money supply feedback rule is as effective as wage indexation. A lagged rule, relevant under a regime of money supply targeting, is also as effective if investors use the interest rate. Both rules have the same implications for the real interest rate as Poole's combination policy. However, the two rules have strikingly different implications for the nominal interest rate.

Monetary Policy without Commitment

American Economic Review 2026 116(7), 2422-2453 open access
This paper studies the implications of central bank credibility for long-run inflation and inflation dynamics. We introduce central bank lack of commitment into a standard nonlinear New Keynesian economy with sticky-price monopolistically competitive firms. Inflation is driven by the interaction of lack of commitment and the economic environment. We show that long-run inflation increases following an unanticipated permanent increase in the labor wedge or decrease in the elasticity of substitution across varieties. In the transition, inflation overshoots and then gradually declines. Quantitatively, inflation overshooting is persistent, and the welfare loss from lack of commitment relative to inflation targeting is large. (JEL D43, E12, E23, E24, E31, E52, E58)

Exchange Rate Dynamics Redux

Journal of Political Economy 1995 103(3), 624-660 open access
We develop an analytically tractable two-country model that marries a full account of global macroeconomic dynamics to a supply framework based on monopolistic competition and sticky nominal prices. The model offers simple and intuitive predictions about exchange rates and current accounts that sometimes differ sharply from those of either modern flexible-price intertemporal models or traditional sticky-price Keynesian models. Our analysis leads to a novel perspective on the international welfare spillovers due to monetary and fiscal policies.

Banking crises: An equal opportunity menace

Journal of Banking & Finance 2013 37(11), 4557-4573 open access
The historical frequency of banking crises is similar in advanced and developing countries, with quantitative parallels in both the run-ups and the aftermath. We establish these regularities using a dataset spanning from the early 1800s to the present. Banking crises weaken fiscal positions, with government revenues invariably contracting. Three years after a crisis central government debt increases by about 86%. The fiscal burden of banking crisis extends beyond the cost of the bailouts. We find that systemic banking crises are typically preceded by asset price bubbles, large capital inflows and credit booms, in rich and poor countries alike.

Reviews of the 2006 Economic Report of the President

Journal of Economic Literature 2006 44(3), 662-693 open access
Editor's Note The Journal of Economic Literature (JEL) regularly reviews books of interest to the economics profession. The Economic Report of the President (ERP) falls under that purview. I have asked a handful of very prominent economists to review the 2006 ERP. Reviewers were chosen to reflect expertise on what I guessed would be key issues. The ERP in principle should provide an accurate assessment of the consensus professional views of economists on any given issue, based on the research to date. Reviewers were asked to evaluate whether the discussion in the ERP in fact accurately summarizes what we as economists know? Reviewers were given free rein over what material they would review in the ERP but were urged to focus on their areas of particular expertise. In the reviews that follow, Martin Feldstein reviews the overview chapter as well as topics relating to macroeconomics. Alan Auerbach reviews the ERP's discussion of tax-related issues, while Ken Rogoff reviews the ERP's discussion of international economic topics. Rebecca Blank writes on labor market issues in the ERP, and Michael Katz reviews the ERP's discussion of health care issues. Many thanks to the reviewers for the quick turnaround.

Exchange Arrangements Entering the Twenty-First Century: Which Anchor will Hold?*

Quarterly Journal of Economics 2019 134(2), 599-646 open access
Abstract This article provides a comprehensive history of anchor or reference currencies, exchange rate arrangements, and a new measure of foreign exchange restrictions for 194 countries and territories over 1946–2016. We find that the often cited post–Bretton Woods transition from fixed to flexible arrangements is overstated; regimes with limited flexibility remain in the majority. Even if central bankers’ communications jargon has evolved considerably in recent decades, it is apparent that many still place a large implicit weight on the exchange rate. The U.S. dollar scores as the world's dominant anchor currency by a very large margin. By some metrics, its use is far wider today than 70 years ago. In contrast, the global role of the euro appears to have stalled. We argue that in addition to the usual safe assets story, the record accumulation of reserves since 2002 may also have to do with many countries’ desire to stabilize exchange rates in an environment of markedly reduced exchange rate restrictions or, more broadly, capital controls: an important amendment to the conventional portrayal of the macroeconomic trilemma.

Recovery from Financial Crises: Evidence from 100 Episodes

American Economic Review 2014 104(5), 50-55 open access
We examine the evolution of real per capita GDP around 100 systemic banking crises. Part of the costs of these crises owes to the protracted nature of recovery. On average, it takes about 8 years to reach the pre-crisis level of income; the median is about 6.5 years. Five to six years after the onset of crisis, only Germany and the United States (out of 12 systemic cases) have reached their 2007-2008 peaks in real income. Forty-five percent of the episodes recorded double dips. Post-war business cycles are not the relevant comparator for the recent crises in advanced economies.

From Financial Crash to Debt Crisis

American Economic Review 2011 101(5), 1676-1706 open access
Newly developed historical time series on public debt, along with data on external debts, allow a deeper analysis of the debt cycles underlying serial debt and banking crises. We test three related hypotheses at both “world” aggregate levels and on an individual country basis. First, external debt surges are an antecedent to banking crises. Second, banking crises (domestic and those in financial centers) often precede or accompany sovereign debt crises; we find they help predict them. Third, public borrowing surges ahead of external sovereign default, as governments have “hidden domestic debts” that exceed the better documented levels of external debt.
