A recent approach to testing for customer statistical discrimination involves studying price gaps between sellers from different gender, race, or ethnic groups and how they evolve as buyers obtain more information about seller quality. We consider a similar setting, testing for statistical...

We define conditions under which sums of dependent spatial data will be approximately normally distributed. A theorem on the asymptotic distribution of a sum of dependent random variables defined on a 3-dimensional lattice is presented. Examples are also presented.

In this paper we investigate if the predictions of three different models of capital adjustment costs are consistent with the observed investment patterns among manufacturing firms in five African countries. We document a high frequency of zero investment episodes, which is consistent with both...
