In a model with heterogeneous-risk-aversion agents facing margin constraints, we show how securities' required returns are characterized both by their betas and their margin requirements. Negative shocks to fundamentals make margin constraints bind, lowering risk-free rates and raising Sharpe...

This chapter studies the differential effects that trade openness may have on leading and lagging regions within a country. Examining data from India, we find that while trade liberalization is associated with reduced poverty, this effect is smaller in lagging states. The expected transmission...

I study the positive relationship between prices of tradable goods and per-capita income. I develop a highly tractable general equilibrium model of international trade with heterogeneous firms and non-homothetic consumer preferences that positively links prices of tradables to consumer income....

Long-run cross-country price data exhibit a puzzle. Today, richer countries exhibit higher price levels than poorer countries, a stylized fact usually attributed to the Balassa- Samuelson' effect. But looking back fifty years, or more, this effect virtually disappears from the data. What is...

The theoretical literature on pricing-to-market has identified two possible reasons why the elasticity of prices to exchange rate changes may be asymmetric across appreciations and depreciations. If firms are attempting to increase market shares in foreign markets subject to the possibility of...

We use a novel dataset of online prices of identical goods sold by four large global retailers in dozens of countries to study good-level real exchange rates and their aggregated behavior. First, in contrast to the prior literature, we demonstrate that the law of one price holds very well within...

We provide three sets of variance decompositions on microeconomic international relative price data. The first shows that the overall distribution of absolute deviations from the Law of One Price (LOP) is dominated by cross-sectional variation in long-term averages, not by time-series variation...

We use a unique panel of retail prices spanning 123 cities in 79 countries from 1990 to 2005, to uncover six novel properties of long-run international price dispersion. First, at the PPP level, virtually all (91.6%) of price dispersion is attributed to service-sector wages, consistent with a...

In this paper a model that analyzes the interaction between changes in commodity export prices, money creation, inflation, and the real exchange rate in a developing country is developed. The model is then tested using data for Colombia. A number of experts have argued that the fluctuations of...

This paper proposes a novel international transmission mechanism based on the assumption of deep habits. The term deep habits stands for a preference specification according to which consumers form habits on a good-by-good basis. Under deep habits, firms face more elastic demand functions in...
