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.

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.

We investigate the causal impact of equity market liberalizations on sectoral export performance across 91 countries (1980–1997). The increased availability of external finance has boosted trade of industries that intensively use relationship-specific inputs, and lowered exports of industries...

This paper investigates the relationship between the diffusion of EU standards and product quality upgrading using highly disaggregated import data to the EU in the food industry. Results show that, on average, the diffusion of EU voluntary standards boosts the rate of quality upgrading....

We hypothesize that exports of differentiated products, which entail greater upfront costs, increase more as financial reforms take place. We find strong and robust empirical support of this hypothesis with a comprehensive set of measures of reforms encompassing the banking sector, interest...

Trade-diversion effects of free trade agreements (FTAs) have not been thoroughly examined empirically. Using a novel empirical approach, we confirm that FTAs divert trade away from non-member countries and even more so from internal trade (domestic sales) in member countries.

I investigate whether the ‘granular’ behaviour of aggregate outcomes suggested by Gabaix (2011) is present in country exports by product. Using data for 11 EU countries over the 1988–2011 period, the results show that the idiosyncratic shocks to the main products may have significant...

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.

One consequence of tariff evasion is that a country’s average statutory import tariff rate deviates from the average applied tariff rate. We deliver an approach to estimate the average evasion rate in multi-country general equilibrium. We find evidence of significant average tariff evasion...
