In economics density forecasts are rarely available, and as a result attention has traditionally focused on poit forecasts of the mean and the use of mean square error statistics to represent the loss function. We extend the methods of forecasts density evaluation in Diebold, Gunther and Tay...

This paper examines the relevance of the well known "no distortion at the top" result in a model of vertical differentiation. The analysis shows that the no crossing condition is a sufficient but not necessary condition in order to get non distortion at the top. relaxing some of the canonical...

Previous sensitivity analysis procedures for applied general equilibrium models have focused on the values of exogenously assigned elasticity parameters, while the calibrated parameters - those that are obtained from combining elasticity information with flow or stock data - have been largely...
