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.

Recently a small and growing empirical literature has attempted to analyze the role that quality plays in our understanding of trade. In particular, the recent work of Khandelwal (2010) has brought the insights of structural IO models of demand to bear into trade data. Our work builds on this...

We study how the 2004 reform of minimum wage rules in China has affected the survival, average wage, employment and productivity of local firms. To identify the causal effect of minimum wage growth, we use firm-level data for more than 160,000 manufacturing firms active in 2003 and complement...

In this paper, we estimate firm-level markups and test some micro-level predictions of a model of international trade with heterogeneous firms and endogenous markups. Our theoretical framework is an extended version of the Melitz and Ottaviano (2008) (MO) model that features both quality and...

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.

In this paper, we study how firm-level export performance is affected by Real Exchange Rate (RER) volatility and investigate the way this effect is shaped by firm size and more specifically, the number of destinations. Our empirical analysis relies on a French firm-level database that combines...

This work investigates the motivations behind the Chinese fiscal policy on exports. It relies on very detailed product level (HS 6 digit) data over the period 2002-12 covering both export tax and export VAT rebate. It aims to uncover the respective importance of the various policy motivations...
