This paper studies a class of multidimensional screening models where different type dimensions lie on the real line. The paper applies preservation results of totally positive functions to show that some critical properties of the distributions of asymmetric information parameters, such as increasing hazard rate, monotone likelihood ratio, and unimodality are preserved under convolution and/or...

I argue for an analysis of imperatives in terms of Classical Logic which takes into account the innuence of background information on imperatives.
