In two recent papers, [Journal of Health Economics 18(2), 141-152, Journal of Health Economics 18(6), 811-824] Nyman raised some questions about the welfare calculations and conclusions in our earlier paper [Manning and Marquis, Health insurance: the tradeoff between risk pooling and moral hazard, Vol. 15, 1996]. This note discusses the erroneous criticisms in his papers. First, although, we es...

Employing more than one supplier and splitting orders between them is a strategy employed in supply chains to lessen the lead-time risk in unstable environments. In this paper we present a multiple-sourcing inventory system with stochastic lead-times and constant demand controlled by a continuous review, reorder point-order quantity inventory policy. We consider the situation in which the order...

Training set size is an important determinant of genomic prediction accuracy. Plant breeding programs are characterized by a high degree of structuring, particularly into populations. This hampers the establishment of large training sets for each population. Pooling populations increases training set size but ignores unique genetic characteristics of each. A possible solution is partial pooling...

The state-of-the-art pooling strategies for perceptual image quality assessment (IQA) are based on the mean and the weighted mean. They are robust pooling strategies which usually provide a moderate to high performance for different IQAs. Recently, standard deviation (SD) pooling was also proposed. Although, this deviation pooling provides a very high performance for a few IQAs, its performance...

This paper analyzes the optimal menu of contracts offered by a risk-neutral principal to risk-averse agent under moral hazard, adverse selection, and limited liability. We show that liability constraint causes pooling most efficient types. also find sufficient conditions which full is optimal, regardless agent's risk aversion or type distribution. Our model suggests offering single contract oft...

Resource flexibility, arguably among the most celebrated operational concepts, is known to provide firms facing demand uncertainty with such benefits as risk pooling, revenue-maximization optionality, and hedging. In this paper, we uncover a heretofore unknown benefit: establish that resource flexibility facilitates learning when latter censored, which could, in turn, enable make better-informe...

Background: Many studies have reported the association of estrogen receptor α gene (ESRα) ESRα PvuII T>C, XbaI A>G and BtgI G>A polymorphisms with Knee osteoarthritis (KOA) risk, but the results remained controversial. In order to drive a more precise estimation, the present systematic review and meta-analysis was performed to investigate the association between ESRα polymorphisms and KOA susce...
