Optimal Design and -Concavity
Tools from advanced real analysis and the Prékopa-Borell Theorem are combined to derive a tight sufficient condition for regularity (R. Myerson, Optimal auction design, Mathematics of Operations Research 6, 1981, pp. 58-73). The conventional log-concavity condition arises as a special case. The approach allows various generalizations, for instance to multidimensional types. Regularity is verifi...
متن کاملExchangeable Optimal Transportation and Log-concavity
We study the Monge and Kantorovich transportation problems on R∞ within the class of exchangeable measures. With the help of the de Finetti decomposition theorem the problem is reduced to an unconstrained optimal transportation problem on a Hilbert space. We find sufficient conditions for convergence of finite-dimensional approximations to the Monge solution. The result holds, in particular, un...
متن کاملKhinchine Type Inequalities with Optimal Constants via Ultra Log-concavity
We derive Khinchine type inequalities for even moments with optimal constants from the result of Walkup ([15]) which states that the class of log-concave sequences is closed under the binomial convolution. log-concavity and ultra log-concavity and Khinchine inequality and factorial moments
متن کاملInfluence of prosthetic design on radiocapitellar concavity-compression stability.
BACKGROUND Radial head prostheses are available with multiple geometric properties. The effect of design features on radiocapitellar stability has not been investigated. HYPOTHESIS The shape (depth and radius of curvature) of the articulating dish of a radial head prosthesis affects radiocapitellar stability. MATERIALS AND METHODS Radiocapitellar stability due to concavity-compression was e...
متن کاملConcavity of Utility, Concavity of Welfare, and Redistribution of Income
The marginal social value of income redistribution is understood to depend on both the concavity of individuals’ utility functions and the concavity of the social welfare function. In the pertinent literatures, notably on optimal income taxation and on normative inequality measurement, it seems to be accepted that the role of these two sources of concavity is symmetric with regard to the social...
