Empirical (employing the Blanchard-Perotti framework) and modeling (using a country-specific DSGE model) approaches are used to estimate fiscal multipliers by policy instrument for Bolivia, to evaluate possible adjustments in a fiscal consolidation strategy. Multipliers are also estimated using alternative assumptions about the accompanying exchange rate regime and capital mobility, highlighting the importance of the policy mix in determining the impact of fiscal adjustments. The study exploits the DSGE modeling structure to assess this interaction of fiscal and monetary policy in a lower middle-income country under different exchange rate regimes. It finds that expenditure multipliers fall into the range of 1/3 to 2/3, with public investment multipliers slightly higher than government consumption multipliers over longer horizons, and multipliers generally higher under a peg than inflation targeting. Tax multipliers are shown to be about half of expenditure multipliers.

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.

Topics discussed in this publication include: an introduction to theoretical and practical aspects of fiscal sustainability; theoretical prerequisites for fiscal sustainability analysis; debt indicators in the measurement of vulnerability; cyclical adjustment of budget surplus; pro-cyclical fiscal policy using Mexico's fiscal accounts as a case study; fiscal rules and the experience of Chile; currency crises and models for deal with financing costs.

The past several years of recession and slow recovery have raised much interest on the effect of fiscal stimulus on economic activity, even as high public debts in many countries would call for fiscal consolidation. To evaluate the delicate balance between stimulus and consolidation requires measuring the size of fiscal multipliers, which often depends on having quarterly data so that exogenous fiscal policy shocks can be identified. We estimate fiscal multipliers using a novel methodology for identifying fiscal shocks within a structural vector autoregressive approach using annual data while controling for debt feedback effects. The estimation focuses on regions with scarce quarterly data (mostly low-income countries), and uses results for advanced economies, emerging market countries, and other broad groupings for which alternative estimates are available to validate the methodology. Differently from advanced and emerging market economies, fiscal consolidation in low-income countries has only a small temporary negative effect on growth while raising medium-term output. Shifting the composition of public spending toward capital expenditure further supports long-run growth.

A New Keynesian model with government production, public compensation, and unemployment is fit to U.S. data to study the macroeconomic and fiscal effects of public wage reductions. We find that accounting for the type of government spending is crucial for its macroeconomic implications. Although reductions in public wages and government purchases of goods have similar effects on total output and the fiscal balance, the former can raise private output slightly, in contrast to the substantial contractionary effects of the latter. In addition, the baseline estimation finds that exogenous public wage reductions decrease private wages. Model counterfactuals show that sufficiently rigid nominal private wages can reverse the response of private wages, as the rigidity dampens the labor reallocation effect from the public to private sector that exerts downward pressure on private wages.

The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

The first part of the book examines the evolution of monetary policy and prudential frameworks of the ASEAN5, with particular focus on changes since the Asian financial crisis and the more recent period of unconventional monetary policy in advanced economies. The second part of the book looks at policy responses to global financial spillovers. The third and last part of the book elaborates on the challenges ahead for monetary policy, financial stability frameworks, and the deepening of financial markets.

The concept of fiscal impulse is defined, discussed, and differentiated from measures that attempt to summarize the macroeconomic effects of fiscal policy. Two methodologies are briefly discussed and their corresponding measures presented for the G-7 countries over the ten-year period ending in 1989. Controversies about the measure are highlighted and potential improvements are also discussed.

This edition of the World Economic Outlook explores how a dramatic escalation of the financial crisis in September 2008 provoked an unprecedented contraction of activity and trade, despite active policy responses. It presents economic projections for 2009 and 2010, and also looks beyond the current crisis, considering factors that will shape the landscape of the global economy over the medium term, as businesses and households seek to repair the damage. The analysis also outlines the difficult policy challenges presented by the overwhelming imperative to take all steps necessary to restore financial stability and revive the global economy, and the longer-run need for national actions to be mutually supporting. The first of two analytical chapters, "What Kind of Economic Recovery?" explores the shape of the eventual recovery. The second, "The Transmission of Financial Stress from Advanced to Emerging and Developing Economies," focuses on the role of external financial linkages and financial stress in transmitting economic shocks.
