"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 proposes a discrete choice duopoly in which products are described and differentiated by their specific attributes. These attributes can be discrete characteristics or differences in continuous variables, such as prices or qualities. Consumers follow a probabilistic reasoning which is...

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....

Over the past two decades, the Maghreb Countries have initiated a liberalization process characterized by increasing trade flows and they have strengthened economic and financial linkages between their economies. In this paper, we demonstrate how co-movements of outputs would respond to this...

This paper studies the influential Melitz model of trade with heterogeneous firms using an alternative, intuitive approach. Contrary to what is often argued, it is an increase in product market competition that drives the bad firms out: with two-way trade, entry by foreign firms is not...

Buyers are typically unaware of the full set of offers when making a purchase. This paper examines how international trade interacts with this problem of market intransparency. Sellers must communicate their offers through costly advertising, but cannot reach all buyers. Consequently, no market...

The objective of the paper is to study Russia's pattern of specialisation in the manufactures trade since 1998. Russia's global trade balance for manufactures is rapidly deteriorating. However, the trade pattern in manufactures should be differentiated according to Russia's main trading...

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,...

We propose a general model of monopolistic competition and derive a complete characterization of the market equilibrium using the concept of Relative Love for Variety. When the RLV increases with individual consumption, the market generates pro-competitive effects. When it decreases, the market...

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...
