In many countries organized as federations, fiscal-equalization schemes have been implemented to mitigate vertical or horizontal imbalances. Such schemes usually imply that the member states of the federation can only partly internalize marginal tax revenue before redistribution. Aside from this...

In the context of EMU fiscal equalization schemes have been proposed as a means to stabilize regions against asymmetric shocks. A theoretical analysis shows that besides reducing the cross-sectional income variance the redistributive element of fiscal equalization causes incentive effects for...

We note that the existence of the maximum likelihood estimates for Poisson regression depends on the data configuration. Because standard software does not check for this problem, the practitioner may be surprised to find that in some applications estimation of the Poisson regression is...

We extend the simulation results given in Santos-Silva and Tenreyro (2006, "The Log of Gravity", The Review of Economics and Statistics, 88, pp.641-658) by considering data generated as a finite mixture of gamma variates. Data generated in this way can naturally have a large proportion of zeros...
