To serve foreign markets, firms can either export or set up a local subsidiary through horizontal Foreign Direct Investment (FDI). The conventional proximity-concentration theory suggests that FDI substitutes for trade if distance between countries is large, while exports become more important...

Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced. Is the correlation spurious and driven by omitted geographical and institutional variables? In this paper, we generalize F&R's...

We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...

This paper studies the intangible costs of international trade by extending the basic gravity equation with measures of cultural and institutional distance, and institutional quality. Analyzing a sample of bilateral trade flows between 92 countries in 1999, we find that institutional distance...

For a long time globalization could be seen everywhere but in gravity estimates. We offer evidence how globalization affects manufacturing trade over the period 1986-2006 and show that, on average, the effect of distance has fallen whereas the effects of proximity and regional trade agreements...

Has the Kyoto Protocol induced carbon leakage? We conduct the first empirical ex-post evaluation of the Protocol. We derive a theoretical gravity equation for the CO2 content of trade, which accounts for intermediate inputs, both domestic and imported. The structure of our new panel database of...
