Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

Market access liberalization has influenced product-specific growth of world exports and contributed to the shift in the structure of world exports of manufactures towards electrical and electronic goods (including parts and components), goods that require high R&D expenditures, and...

Starting with Tinbergen (1962), quantifying the effects of regional trade agreements (RTAs) on international trade flows has always been among the most popular topics in the trade literature. Also not surprisingly, to estimate the effects of RTAs, most researchers and policy analysts have relied...

This paper documents the novel fact that Regional Trade Agreements (RTA) decrease bilateral trade imbalances as measured by conventional measure of the net export share in gross trade. While on average an RTA decreases bilateral trade imbalance by 7%, greater trade integration through a deeper...

This paper investigates empirically how similarity of demand structures - approximated by similarity of income distributions - affects trade patterns along both the extensive and intensive margin. The idea that similarity of demand structures intensifies trade goes back to the well-known Linder...

The firms' international fragmentation of production has recently widened its focus from outsourcing of intermediates to off-shoring of business services such as software program development and international call centre networks. Although a large number of business services are intangible and...

Helpman, Melitz and Rubinstein (2008) derive gravity equations to estimate effects of trade barriers on the intensive and extensive margins of trade. They exploit the frequency of zeros in aggregate bilateral trade data to identify effects on the extensive margin and to obtain controls for firm...

This paper compares various estimation methods often used in the estimation of gravity models of international trade. The authors first discuss different structural and consistent estimation techniques, their underlying assumptions and their impact on estimated coefficients. They then estimate...

This paper compares various estimation techniques used to determine the impact of distance and borders on international trade. The results consistently confirm the significantly negative distance effect, while the border effect, measured by evaluating whether intra-continental trade exceeds...
