World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have not traded with each other in the past...

Much potential for trade liberalization exists in industries and markets with trade barriers that are prohibitive for all or many firms. In standard political economic theories of trade policy, observed prohibitive barriers must be globally optimal according to static government preferences,...

Multinational enterprises (MNEs) are increasingly dealing with challenges shaped by the new geopolitical and trade environments. Besides traditional tariffs, exporting firms need to comply with regulatory non-tariff measures (NTMs) in the form of technical barriers to trade (TBTs) and sanitary...

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)...

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...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

This paper analyses international patterns of bilateral portfolio equity and debt investment in a gravity model framework. We contribute to the literature by exploring the role of virtual proximity – measured by bilateral internet hyperlinks between countries – as a novel proxy for...
