We develop a theory of financial intermediary leverage cycles in the context of a dynamic model of the macroeconomy. The interaction between a production sector, a financial intermediation sector, and a household sector gives rise to amplification of fundamental shocks that affect real economic...

This paper provides evidence on the effect of fiscal stimulus on economic activity in countries with different degrees of institutional quality. The identification strategy makes use of data on military expenditure to instrument government consumption using local lineal projections as presented...

We review evidence on the Great Moderation together with evidence about volatility trends at the micro level to develop a potential explanation for the decline in aggregate volatility since the 1980s and its consequences. The key elements are declines in firm-level volatility and aggregate...

The authors provide empirical evidence on the dynamic effects of tax liability changes in the United States. We distinguish between surprise and anticipated tax changes using a timing convention. We document that pre-announced but not yet implemented tax cuts give rise to contractions in output,...

Tiny changes in the American monetary policy can have dramatic effects on the rest of the world because of dollar's double role of national and international currency. This is the Triffin dilemma. The paper shows how it works through three examples: price of commodities, dollarization, and the...

A recent theoretical literature highlights the role of endogenous firm entry as an internal amplification mechanism of business cycle fluctuations. The amplification mechanism works through the competition and the variety effect. This paper tests the significance of this amplification mechanism,...
