It is well known that the long-run viability of a fixed exchange rate regime imposes constraints on monetary policy. This paper shows that, in a model with forward-looking agents, short-run viability imposes a fiscal constraint. When policy change, which destroys long-run viability, also violates the fiscal constraint, collapse is instantaneous. Delayed predictable collapse requires satisfaction of the fiscal constraint.

This paper reviews the literature on financial crises focusing on three specific aspects. First, what are the main factors explaining financial crises? Since many theories on the sources of financial crises highlight the importance of sharp fluctuations in asset and credit markets, the paper briefly reviews theoretical and empirical studies on developments in these markets around financial crises. Second, what are the major types of financial crises? The paper focuses on the main theoretical and empirical explanations of four types of financial crises—currency crises, sudden stops, debt crises, and banking crises—and presents a survey of the literature that attempts to identify these episodes. Third, what are the real and financial sector implications of crises? The paper briefly reviews the short- and medium-run implications of crises for the real economy and financial sector. It concludes with a summary of the main lessons from the literature and future research directions.

The recent recession has brought fiscal policy back to the forefront, with economists and policy makers struggling to reach a consensus on highly political issues like tax rates and government spending. At the heart of the debate are fiscal multipliers, whose size and sensitivity determine the power of such policies to influence economic growth. Fiscal Policy after the Financial Crisis focuses on the effects of fiscal stimuli and increased government spending, with contributions that consider the measurement of the multiplier effect and its size. In the face of uncertainty over the sustainability of recent economic policies, further contributions to this volume discuss the merits of alternate means of debt reduction through decreased government spending or increased taxes. A final section examines how the short-term political forces driving fiscal policy might be balanced with aspects of the long-term planning governing monetary policy. A direct intervention in timely debates, Fiscal Policy after the Financial Crisis offers invaluable insights about various responses to the recent financial crisis.

This paper reviews the theoretical and empirical literature on the effectiveness of fiscal policy. The focus is on the size of fiscal multipliers, and on the possibility that multipliers can turn negative (i.e., that fiscal contractions can be expansionary). The paper concludes that fiscal multipliers are overwhelmingly positive but small. However, there is some evidence of negative fiscal multipliers.

This paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.

The pamphlet (which updates the 1995 Guidelines for Fiscal Adjustment) presents the IMF’s approach to fiscal adjustment, and focuses on the role that sound government finances play in promoting macroeconomic stability and growth. Structured around five practical questions—when to adjust, how to assess the fiscal position, what makes for successful adjustment, how to carry out adjustment, and which institutions can help—it covers topics such as tax policies, debt sustainability, fiscal responsibility laws, and transparency.
