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.

The paper estimates the long-run elasticities of import demand in Jordan over the period 1980-2004. The Engle-Granger test of co-integration, fails to find favor of a long-run relationship among variables associated with an import demand. Furthermore, the recently prescribed Stock-Watson Dynamic...

Combining Balassa–Samuelson effects with strategic complementarities between prices of tradables and non-tradables yields a novel determinant of tradables’ prices. A larger productivity difference between tradables and non-tradables raises the non-tradables’ price. With strategic...

Price dispersion of US imports are investigated across US districts of entry. Markups explain about 31% of price dispersion, while marginal costs of production explain about 69%; effects of trade costs, for which we have actual data, are almost none.

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 examine learning-by-exporting effects of manufacturing and services firms in 19 sub-Saharan African countries. Comparing several outlier-robust estimators, our results provide evidence for positive effects in the manufacturing sector when using the MM estimator, but not in the services sector.

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.

This study examines the trade flows in commodities for CARICOM countries through the utilization of the traditional gravity model for international trade. Per capita GDP differential, trade to GDP and language all impact trade positively. On the other hand, geographical distance, exchange rate...

This paper uses plant-level data from Chile to show that an increase in sector-wide exports decreases the survival probability of exporters, but not that of non-exporters. We argue that this result can be explained by the fact that exporters and non-exporters use factors of production in...

The prevalence of Internet-based sales was highlighted by the World Bank (Ferro, 2011) associating state-of-art technology with exporters. We use propensity score kernel matching with difference-in-differences to reveal export selection and evidence of ‘technology upgrading’ through higher...
