We demonstrate that the Varian (1980) model of sales has a unique Nash equilibrium when firms incur costly advertising to compete for informed consumers. The equilibrium is symmetric. In particular, with costly advertising, the asymmetric equilibria highlighted by Baye et al. (1992) do not arise.

Depuis le début des années 2000, la France a connu une détérioration marquée de sa performance à l’exportation, conduisant à des préoccupations accrues de la part des autorités et de la société civile sur la capacité d’adaptation de l’économie à une mondialisation croissante...

L’ouverture de la Tunisie aux échanges internationaux et son intégration dans les chaines de valeur mondiales ont fortement progressé depuis le milieu des années 90, témoignant des avantages comparatifs du pays. Les exportations ont sensiblement augmenté, tirées par le secteur...

We show that, in general, consistent estimates of cost pass-through are not obtained from reduced-form regressions of price on cost. We derive a formal approximation for the bias that arises even under standard orthogonality conditions. We provide guidance on the conditions under which bias may...

We analyze the sourcing strategies of firms active in the Spanish manufacturing sector. We show that firms that select strategies of vertical integration and of foreign sourcing ex post tend to have been more productive, ex ante, than other firms.

The constant market share analysis framework is used to decompose changes in Spain’s share of the global market for goods exports into competitiveness and structural effects (i.e. the impact of specialisation, either in product or geographical terms) over 1996-2013. As other high-income...

This paper quantifies the importance of different determinants of trade at the industry level using a sample of 54 OECD and non-OECD economies. The empirical methodology extends the approach of previous empirical studies to explicitly quantify the impact that trading partners’ factor...

Several studies have reported a large negative effect of national borders on the volume of trade. We provide new estimates of the border effect for continental Europe using road rather than great circle – or “as-crows-fly” – distance. Road distances for 48 180 European city pairs have...

This paper provides a detailed description of recent research to re-estimate and re-specify the international trade volume and price equations that are used in the OECD Economics Department to analyse and project international trade developments. The set of countries covered by the estimations...

Gravity models are used to explore the determinants of trade, making use of fixed effect linear estimators and a Poisson estimator (as in Santos Silva and Tenreyro, 2006) with fixed effects. Beyond usual determinants of trade such as GDP, distance, contiguity, free trade areas and language, this...
