Very few exact solutions are known for the monopolist’s k-item n-buyer maximum revenue problem with additive valuation in which k, n > 1 and the buyers i have independent private distributions F j i on items j. In this paper we derive exact formulas for the maximum revenue when k = 2 and F j i are any IID distributions on support of size 2, for both the dominant-strategy (DIC) and the Bayesian ...

This paper proposes mixture models for spatially adaptive smoothing of health event data (e.g. mortality or illness totals). Such models allow for spatial pooling of strength but adopt a mixture strategy that also reflects health risks that are discordant with those of surrounding areas. Mixing is either discrete or based on beta densities. A fully Bayesian estimation and specification strategy...
