Under the recent framework developed in the European Union to extend the use of higher capacity goods vehicles, this article originally analyzes how different truck configurations by load capacity, impact road safety. Through the application of econometric techniques to panel data for EU28 and controlling for explanatory variables, we find that increased truck load capacity does not necessarily get worse traffic safety. Specifically, heavy trucks do not seem to be associated with more traffic fatalities/accidents, medium trucks appear to be the worst performers for fatalities and lighter trucks the worst for accidents.

This article provides a meta-analysis of a selected sample of 87 estimates from studies based on panel data techniques published through until 2012. The purpose is to obtain a summary measure of the effects of tourism on economic growth by applying models for both fixed and random effects. The results show a positive elasticity between GDP and tourism, although the magnitude of the effect varies according to the methodological procedure employed in the original studies for empirical estimates. In this sense, when estimates exclude other explanatory variables of economic growth, elasticities are overvalued.
