Traditional trade models ignoring the dimension of product quality generally lead to excessively low trade price elasticities. In this paper, we show that higher estimated trade price elasticities, more in conformity with theory, can be obtained by controlling product quality in trade equations....

"Elimination by aspects" (EBA) is a discrete model of probabilistic choice worked out by Tversky in 1972 which supposes that decision makers follow a particular heuristic during a process of sequential choice. Options are described by their attributes and, at each decision stage, the individuals...

This paper studies how market-specific entry sunk costs (regulation costs) affect the Home Market Effect (HME) with firm heterogeneity in marginal costs. our model is based on the Dixit-Stiglitz monopolistic competition model with firm heterogeneity plus regulation costs difference. We find that...

Most of the theoretical and empirical studies on the Home Market Effect (HME) assume the existence of an \outside good" that absorbs all trade imbalances and equalizes wages. We study the consequences on the HME of removing this assumption. The HME is attenuated and, more interestingly, it...

The crisis between Russia and Georgia in August 2008 highlights the fragility and instability of transporting gas from the Caspian and Central Asia to Europe via the "Caucasus transit corridor". The feasibility of one of the EU's possible strategies for diversifying its energy supplies might now...

Product diversity is a long-debated issue in economics. We remind that mainly two questions have been given answers : (a) To which extent does the market provide diversity ? (b) Why should this diversity be promoted ? The first one stands out as the core of most articles on product diversity,...

This paper analyzes anti¬dumping (AD) policies in a two-country model with heterogeneous firms. One country enforces AD so harshly that firms exporting to the country choose not to dump. In the short run, the country enforcing AD experiences reduced com¬petition to the benefit of local firm...
