Following Santos Silva and Tenreyro (2006), various studies have used the Poisson Pseudo-Maximum Likelihood to estimate gravity specifications of trade flows and non-count data models more generally. Some papers also report results based on the Negative Binomial estimator, which is more general...

Estimations of gravity equations specified in logarithm generally conclude that the distance elasticity of trade has increased over time despite globalization. In contrast, building on Santos Silva and Tenreyro (2006), this elasticity is estimated to have been stable around 0.65-0.70 since the...

This paper gives estimates of sectoral markup trends in thirteen OECD countries over the last three decades. It concludes with a slight, albeit heterogeneous, increase in price-cost margins (PCMs) overall, contrary to the generally expected effect of increased competition. More strikingly, it...

Previous analyses showed that product market deregulation often precedes labor market (LM) reforms. This paper introduces LM imperfections within an economic geography framework, the level of optimal LM regulation being based on each country's social preferences. Due to capital mobility, opening...

This study analyzes the determinants of price-cost margins (PCMs) for OECD countries between 1970-2003. The main objective is to quantify the pro-competitive effect of international trade and understand why, despite trade liberalization, PCMs have not fallen overall. An increase of one...

The treatment of capital costs, as either fixed or variable, is key for estimating markups. Data leans clearly towards fixity, which explains the high markups emphasized in previous studies based on Roeger's methodology. Direct estimation from the ratio of output over variable costs is preferable.

There is ample evidence that a country's labour market institutions are important determinants of unemployment. This study generalises Davis' (1998) idea according to which the institutions of the trade partners matter also for a country's equilibrium unemployment rate as they generate...
