The Bank of England''s current ""quantitative easing"" strategy has given rise to a controversial debate about the effects and risks of unconventional monetary policy. The present paper makes two contributions to this debate. First, it provides a systematic overview of unconventional policy...

This paper studies inflation dynamics during 25 historical episodes in advanced economies where output remained well below potential for an extended period. We find that such episodes generally brought about significant disinflation, underpinned by weak labor markets, slowing wage growth, and,...

In view of increasing geopolitical tensions, the economic consequences and costs of wars on the global economy are increasingly coming into focus. In their Kiel Policy Brief, the authors examine the costs of more than 150 wars since 1870. In the immediate theaters of war alone, real GDP falls by...

In an integrated global economy, the economic fallout of war is not confined to the country where the conflict is fought but spills over to other countries. We study the economic effects of large interstate wars using a new data set spanning 150 years of data for more than 60 countries. War on a...

Amid escalating geopolitical tensions, we offers insights into the far-reaching consequences of wars. Based on a new dataset on major conflicts since 1870, the findings show that wars cause a substantial decline in GDP and spike in inflation within war zones. Interestingly, countries...

The impact of fiscal stimulus depends not only on short-term tax and spending policies, but also on expectations about offsetting measures in the future. This paper analyzes the effects of an increase in government spending under a plausible debt-stabilizing policy that systematically reduces...

Recent theoretical contributions have suggested consumption externalities, or peergroup effects, as a potential explanation for some of the puzzles in macroeconomics and finance. However, the empirical relevance of peer effects for intertemporal consumption choice is a completely open question....

Financial frictions affect the way in which different components of GDP respond to a monetary policy shock. We embed the financial accelerator of Bernanke, Gertler and Gilchrist (1999) into a medium-scale Dynamic General Equilibrium model and evaluate the relative importance of financial...
