Optimal Design and -Concavity
نویسنده
چکیده
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 verified explicitly for numerous new families of parameterized distributions. Economic applications are outlined, in particular to the robustness of the modified Vickrey auction.

Evaluation of the concavity depth and inclination in jaws using CBCT
Introduction: Nowadays, using implants as a choice in patient's treatment plans has become popular. The aim of this study was to determine the prevalence of mandibular lingual and maxillary buccal concavity, mean concavity depth and angle and its relation to age and gender. Materials and Methods: In 200 CBCT, concavity depth and angle were measured in 2 mm superior to the inferior alveolar c...
متن کاملContinuity in Mechanism Design without Transfers
We adopt a mechanism design approach to model communication between a principal and a privately informed agent in the context where monetary incentives are not available. We provide a simple condition on the distribution of the agent’s type which ensures that the optimal mechanism is continuous. With strict log-concavity of the distribution, there exists a unique optimal mechanism that is chara...

This paper establishes structural properties of the throughput of a large class of queueing networks with i.i.d. new-better-than-used service times. The main result obtained in this paper is applied to a wide range of networks including tandems, cycles and fork-join networks with general blocking and starvation as well as certain networks with splitting-merging of traac streams, to deduce conca...

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 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...
