Competitiveness has come to the forefront of the policy debate within the European Union, focusing on price competitiveness and intra-EU imbalances. But how to measure properly competitiveness, beyond price or cost competitiveness, remains an open methodological issue; and what is the resilience...

Using an econometric shift-share decomposition, we explain the redistribution of world market shares at the level of the product variety and by technological content. We decompose changes in market shares into structural eff ects (geographical and sectoral) and a pure performance e ffect. We...

We study international competition in high-end products for 416 detailed HS6 product categories marketed by leading French luxury brands. We construct a world database of trade flows for these products in the period 1994-2009, computing unit values of related bilateral trade flows and analyzing...

Countries no longer specialise in products or sectors, but in varieties of the same product (sold at different prices). To study the way in which the European Union copes with the emergence of new big world exporters in this context, we analyse the redistribution of world market shares at the...

This paper sets out to model the evolution of market shares in the semiconductor industry. The time profile of market shares for different firms in this industry has shown a striking regularity over successive generations of products. In a model of vertical product differentiation three distinct...

In the wake of falling trade costs, two central consequences in the importing economy are, first, that stronger competition through increased imports can lead to market share reallocations among domestic firms with different productivity levels (selection). Second, the increase in imports might...

This paper studies the price dynamics induced by strategic firm behaviour in the presence of consumer learning about the uncertain quality differential of the products offered by a duopoly. It is found that consumers learn slowly and also that prices converge slowly to full-information levels. A...

The study of export performance, especially for countries with serious external imbalances, is essential for economic decision-making. This study attempts to evaluate Greek export performance during the 1996-2006 period, using detailed panel data on bilateral trade by product. Factors explaining...

Purpose – The purpose of this paper is to examine the effects of generic medicine competition on the market share growth and pricing of originator brand medicine in the South African private pharmaceutical market. Design/methodology/approach – Regression analysis is applied to market share...

Market share models for weekly store-level data are useful to understand competitive structures by delivering own and cross price elasticities. These models can however not be used to examine which brands lose share to which brands during a specificperiod of time. It is for this purpose that we...
