The importance of trade costs in segmenting product markets cannot be captured by considering aggregate prices or in the absence of information on the direction of trade. We address this problem by utilizing product-specific prices along with cross-sectional productivity measures and bilateral...

Does medical technology originating in countries close to the technology frontier have a significant impact on health outcomes in countries distant from this frontier? This paper considers a framework where lagging countries may benefit from medical technology (a result of research and...

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...

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...

This paper compares the determinants of economic growth and welfare growth. Our main result is that determinants may differ or have different impact on welfare outcomes as compared to economic outcomes. Human capital plays a bigger role in determining the former, so that policies targeting human...

This paper considers the relation between immigration and prices for a large number of cities across the world over the period from 1990 to 2006. Aggregate immigration ratios are shown to have a negative impact on international relative prices. The evidence is consistent with demand-side and...

We use a panel of thousands of good-level prices before and after the euro in order to compare the determinants and understand the evolution of goods price dispersion across Europe during these two periods. We find that tradeability plays a substantially smaller role in lowering cross-country...

This paper investigates the determinants of longevity at a macroeconomic level, emphasizing the important role played by education. To analyze the determinants of longevity, we build a model where households intentionally invest in health and education, and where education exerts external...

The empirical literature finds mixed evidence on the existence of positive productivity externalities in the host country generated by foreign multinational companies. We propose a mechanism that emphasizes the role of local financial markets in enabling foreign direct investment (FDI) to...

Recently Acemolgu, Aghion, Bursztyn and Hemous (AER 2012) formulated a model in which a high macroeconomic elasticity of substitution between clean and dirty production represents a crucial condition for green growth. Until now it has never been systematically estimated. Using a novel panel of...
