I propose a network/search view of international trade in differentiated products. I present evidence that supports the view that proximity and common language/colonial ties are more important for differentiated products than for products traded on organized exchanges in matching international...

The aim of this paper is to review the state of art regarding the theoretical foundations of gravity equations applied to trade flows. Micro-foundations of the supply side and of the demand side are presented such as new models where a) general equilibrium constraints are taken into account b)...

The impact of international trade, or “openness”, on economic growth is difficult to quantify because of reverse causality. In this paper, I use recent advances in gravity equation estima- tion to generate a geography-based instrument for openness a la Frankel and Romer (1999). In contrast...

A gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade. The panel data set used includes bilateral observations for five years spanning 1970 through 1990 for 186 countries. In this data set, there are over one hundred...

The conventional immigration and trade literature regards immigrants as mediators for informal barriers such as institutional and cultural differences. However, this notion neglects network effects stemming from short visits. This paper investigates the ways in which international student...

The first-in, first-out (FIFO) queue discipline respects the order of arrival but is not efficient when customers have heterogeneous waiting costs. Priority queues, in which customers with higher waiting costs are served before customers with lower waiting costs, are more efficient but usually...
