Pharmaceutical markets are characterized by a high degree of innovation, complexity and uncertainty, especially markets of idiosyncratic symptomatolgy and response to treatment such as the antidepressant market. It may, therefore, be unreasonable to assume that consumers are aware of all...

A number of recent papers point to the importance of distinguishing between the price reaction to micro and macro shocks in order to reconcile the volatility of individual prices with the observed persistence of aggregate inflation. We emphasize instead the importance of distinguishing between...

Recent work in the growth literature has provided various explanations for transition delays and the great divergence. This paper provides empirical support for one theory of transition delays: initial land inequality. Our analysis is designed to elucidate the channels via which land inequality...

Barro and McCleary (2003) is a key research contribution in the new literature exploring the macroeconomic effects of religious beliefs. This paper represents an effort to evaluate the strength of their claims. We evaluate their results in terms of replicability and robustness. Overall, their...

Recessions are times when the quality of the unemployment pool is lower, because entry into unemployment is biased in favor of low-productivity workers. I develop a search and matching model with worker heterogeneity and endogenous separations that has this feature. I show that in a recession a...

We analyze the impact of immigration on the host country within a search and matching model that allows for skill heterogeneity, endogenous skill acquisition, differential search cost between immigrants and natives, capital-skill complementarity and different degree of substitutability between...

Quantity surcharges occur when firms market a product in two sizes and offer a promotion on the small size: the large size then costs more per unit than the small one. When quantity surcharges occur the sales of the large size decrease only slightly despite the fact that the small size is a...

We exploit the panel dimension of a price levels dataset for more than one hundred product items across 140 cities in 90 countries for the period from 1990 to 2009 in order to improve our understanding of international price dispersion and the evolution of prices over time. We consider a panel...

Did the rise in anti-American sentiment caused by the Iraq war affect sales of US goods abroad? We address this question using data on sales of soft drinks and fabric detergents in nine Arab countries. We find a statistically significant but modest and short-lived negative impact of the war on...

We introduce easy to implement regression-based methods for predicting quarterly real economic activity that use daily financial data and rely on forecast combinations of MIDAS regressions. Our analysis is designed to elucidate the value of daily information and provide real-time forecast...
