We propose a new instrument to identify uncertainty shocks in a SVAR model with external instruments. The instrument is constructed by exploiting variations in the price of gold around events that capture periods of changes in uncertainty. The variations in the price of gold around the events...

In this paper, we conduct an empirical study of the effect of uncertainty on fertility. The precautionary motive for saving predicts that an increase in uncertainty increases saving by reducing both consumption and fertility. We use a new measure of uncertainty, the World Uncertainty Index, and...

In his presidential address to the American Economic Association, Robert Lucas claimed that the welfare costs of the business cycle in the United States equaled .05 percent of consumption. His calculation compared the utility of a representative consumer receiving actual per-capita consumption...

The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov...

We characterize the dispersion of firm-level productivity and demand shocks over the business cycle using Swedish microdata including prices and analyse the consequences for firms and the aggregate economy. Demand dispersion increases by more than productivity dispersion in recessions....

We propose a new instrument to identify the impact of uncertainty shocks in a SVAR model with external instruments. We construct the instrument for uncertainty shocks by exploiting variations in the price of gold around selected events. The events capture periods of changes in uncertainty...

In diesen Tagen jährt sich der Tod von John Maynard Keynes zum 75. Mal. Er war einer der bedeutendsten Ökonomen des 20. Jahrhunderts, wenn nicht gar der bedeutendste überhaupt. Dabei waren seine Lehren und seine Ratschläge schon zu seinen Lebzeiten teilweise heftigst umstritten. Das galt...

We characterize the dispersion of firm-level productivity and demand shocks using Swedish microdata including prices and utilization and analyse the consequences for firms and the aggregate economy. Demand dispersion increases by more than TFPQ dispersion in recessions. Productivity shocks pass...

This paper combines the recent game theoretic approach of endogenous timing of entry to herding models with a macroeconomic model of investment cycles. The integrated description embodies the qualitative results of the myopic herding model in a medium run investment objective of smoothing the...

In situations of what we now describe as radical uncertainty, the core model of agent behaviour, of rational autonomous agents with stable preferences, is not useful. Instead, a different principle, in which the decisions of an agent are based directly on the decisions and strategies of other...
