Models of the microfoundations of nominal price rigidities show that in the absence of real rigidities, individual firms have strong incentives to adjust prices even if other firms do not: price rigidity is not a Nash equilibrium unless the fixed cost of adjusting prices is implausibly high....

In this paper, we study the macroeconomic implications of sectoral heterogeneity and, in particular, heterogeneity in price setting, through the lens of a highly disaggregated multi-sector model. The model incorporates several realistic features and is estimated using a mix of aggregate and...

A chief goal of the Pigou cycle literature is to generate a boom in response to news of a future increase in productivity, and a bust if this improvement does not in fact take place. We nd that monetary policy can generate Pigou cycles in a two sector model with durables and non-durables, and...

This paper proposes a new nonparametric test for conditional independence, which is based on the comparison of Bernstein copula densities using the Hellinger distance. The test is easy to implement because it does not involve a weighting function in the test statistic, and it can be applied in...

This paper constructs and estimates a sticky-price, Dynamic Stochastic General Equilibrium model with heterogenous production sectors. Sectors differ in price stickiness, capital-adjustment costs and production technology, and use output from each other as material and investment inputs...

The key element in the tension between those who believe climate change is an issue and those who do not is essentially the question of whether we are merely in a long period of shock-induced above average temperatures or if we have led to this increase in temperatures by anthropogenic carbon...

We analyze the complementarity between legal incentives (the threat of being held liable for damages) and normative incentives (the fear of social disapproval or stigma) in situations where instances of misbehavior are not perfectly observable. There may be multiple equilibria within a given...
