Governments in emerging markets often behave like a quot;tormented insurer,quot; trying to use non-state-contingent debt instruments to avoid cuts in payments to private agents despite large fluctuations in public revenues. In the data, average public debt-GDP ratios decline as the variability...

We contribute to the debate on the macroeconomic effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a...

This paper characterizes the dynamic effects of shocks in government spending and taxes on economic activity in the United States in the post-war period. It does so by using a mixed structural VAR/event study approach. Identification is achieved by using institutional information about the tax...

We show that a fiscal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model specification, an expansion of core government spending equal to one percent of...

After three years of near stagnation, the mood in Europe is definitely gloomy. Many doubt that the European model has a future. In this paper, I argue that things are not so bad, and there is room for optimism. Over the last thirty years, productivity growth has been much higher in Europe than...

Two key facts about European unemployment must be explained: the rise in unemployment since the 1960s, and the heterogeneity of individual country experiences. While adverse shocks can potentially explain much of the rise in unemployment, there is insufficient heterogeneity in these shocks to...

The recent European experience of high persistent unemployment has led to the development of theories of unemployment hysteresis embodying the idea that the equilibrium unemployment rate depends on the history of the actual unemployment rate. This paper summarizes two directions of research on...

How high can public debt rise without compromising fiscal solvency? We answer this question using a stochastic ability-to-pay model of sovereign default in which risk-neutral investors lend to a government that displays "fiscal fatigue," because its ability to increase primary balances cannot...

Violations of Tinbergen rule and strategic interaction undermine monetary and financial policies in a New Keynesian model with the Bernanke-Gertler accelerator. Welfare costs of risk shocks are large because of efficiency losses and income effects of costly monitoring, but they are larger under...

This paper looks at fiscal solvency and public debt sustainability in both emerging market and advanced countries. Evidence of fiscal solvency, in the form of a robust positive conditional relationship between public debt and the primary fiscal balance, is established in both groups of...
