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 both individual and joint...

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...

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,...

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...

What is the effect of nominal exchange rate variability on trade? I argue that the methods conventionally used to answer this perennial question are plagued by a variety of sources of systematic bias. I propose a novel approach that simultaneously addresses all of these biases, and present new...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

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)...

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....
