Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this paper, we show that this trade-promoting effect of language...

Two large but separate bodies of literature analyze the economic effects of international trade and immigration. Given that several factors are important determinants of both trade and migration flows, the previous studies are vulnerable to a potentially serious omitted-variables bias,...

Our paper deals with econometric developments for the estimation of the gravity model which lead to convergent parameter estimates even when a correlation exists between the explanatory variables and the specific unobservable characteristics of each unit. We implement panel data econometric...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

This paper investigates the feasibility of creating a common-currency union consisting of 16 countries in Southern Africa. We estimate an augmented-gravity model that includes public deficit, public debt, public expenditure, inflation, and the foreign reserves position. We also integrate...

Acquiring information about destinations can be costly for migrants. We model information frictions in the rational inattention framework and obtain a closed-form expression for a migration gravity equation that we bring to the data. The model predicts that ows from countries with a higher cost...

Exploiting recent concentration of flight patterns under a new Federal Aviation Administration policy (called NextGen), we examine the impact of exposure to excessive noise levels on birth outcomes. Using birth records that include mothers’ home addresses to measure airport proximity, we find...

We explore two unexpected changes in flight regulations to identify the causal effect of aircraft noise on health. Detailed yearly noise metrics are linked with panel data on health outcomes using exact address information. Controlling for individual and spatial heterogeneity, we find that...

The paper analyzes wages in the U.S. airline industry, focusing on the role of collective bargaining in a changing product market environment. Airline unions have considerable strike threat power, but are constrained by the financial health of carriers. Since airline deregulation, compensation...

Airline fuel consumption is costly for the firms and for society as well due to a climate-change externality. We study how fuel price changes affect cost-minimizing choices by airlines that have implications for the extent of this externality. The airline industry's capital stock can be easily...
