Recently, various studies have used the Poisson Pseudo-Maximal Likehood (PML) to estimate gravity specifications of trade flows and non-count data models more generally. Some papers also report results based on the Negative Binomial Quasi-Generalised Pseudo-Maximum Likelihood (NB QGPML)...

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...

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...

This paper studies the change in the distance elasticity of trade between 1948 and 2006. The elasticity sharply increased, when gravity equations are estimated by ordinary least squares in log form (log-OLS), while it was broadly stable or slightly increasing, depending on the specification,...

Between 1950 and 1973, a process of absolute convergence was at work between the technological leader, the USA, West European countries and Japan. The catching up process between developed countries gradually vanished between 1973 and 1995. On the one hand, we had a revival of US labour...

Si les écarts entre les hommes et les femmes de taux d'emploi global et de salaires, à caractéristiques observables données, dont le type d'emploi, sont devenus très faibles, il n'en reste pas moins que les femmes occupent moins fréquemment des postes à haute responsabilité, mieux...
