This paper presents a theoretical gravity model of trade in which foreign aid is considered as a transfer instead of being part of the trade cost, as it has been previously done in the related literature. We argue that the usual specification leads to invalid out-of-sample predictions, biased...

This paper assesses whether the sensitivity of bilateral trade volumes to various trade cost factors is constant or varies across countries. It utilizes a random coeffcients model and analyses a cross-sectional sample of bilateral trade data for 96 countries in 2005. We expect the elasticity of...

This paper examines the impact of capital market integration (CMI) on higher education and economic growth. We take into account that participation in higher education is noncompulsory and depends on individual choice. Integration increases (decreases) the incentives to participate in higher...

This paper evaluates the performance of alternative estimation methods for multiplicative and log models with heteroskedasticity. Contrary to Santos Silva and Tenreyro (2006), the results of a simulation study indicate that the Pseudo Poisson Maximum Likelihood estimator (PPML) is not always the...
