Relative efficiencies of antebellum slave farms are suggested by many empirical studies. This paper considers a theoretical aspect of those results using a repeated principal-agent problem. Within its theoretical analysis, with relevance to profitability of slave farms, it will be shown that...

A very general measure of skewness based on the quantiles is introduced, which includes several well-known measures as special cases. Sample versions of our measure may be used as test statistics for testing the hypothesis of symmetry about an unknown value. We provide large sample theory for...
