Kidney exchange provides a life-saving alternative to long waiting lists for patients in need of a new kidney. Fielded exchanges typically match under utilitarian or near-utilitarian rules; this approach marginalizes certain classes of patients. In this paper, we focus on improving access to kidneys for highly-sensitized, or hard-tomatch, patients. Toward this end, we formally adapt a recently ...

The paper establishes a fairness preference framework based on game theory of Nash bargaining, and builds a utility system about fairness preference. On the basis, we expeands the newboy model to behavior research. The analysis shows that because of the retailer and suppliers’ fairness preference, their optimal order quantities tend to became conservative, and the result shows that the greater ...

Do online recommendations have the same motivating impact as price at the point-of-onlinepurchase? The results (n=273) of an conjoint study show that: (1) when the price is low or high relatively to market price, it has the strongest impact (positive and negative) on the likelihood of an online purchase of an mp3 player, (2) when the price is average to market price, online recommendation and p...

We propose a model to describe stock pinning on option expiration dates. We argue that if the open interest on a particular contract is unusually large, delta-hedging in aggregate by floor market-makers can impact the stock price and drive it to the strike price of the option. We derive a stochastic differential equation for the stock price which has a singular drift that accounts for the price...

Recently, and especially in expanding markets, firms put an extraordinary emphasis on customer satisfaction, sometimes treating it as a superior measure of a company performance to current earnings. While customer satisfaction increases future profits through the effect of positive consumer feedback on future demand, customer satisfaction efforts have a shortterm cost. Therefore, a question ari...

The paper considers the macroeconomic impact of shocks to agricultural output and of negative and positive price shocks. It is shown that negative price shocks have particularly large externalities: it is estimated that the overall impact of these negative shocks on GDP may well be double their direct impact. In terms of policy, the presence of externalities justifies subsidising the provision ...

this study uses vector error correction model to examine the effects of oilseeds, crude oil and vegetable oil tariffs on vegetable oil consumer price. monthly data sets for the years 2004-2013 and var and vecm models were applied for this study. research findings indicates only a long term equilibrium relation between the study variables .the effect of vegetable oil tariffs on consumer and prod...

This paper proposes a theory of price rigidity consistent with survey evidence that firms stabilize prices out of fairness to their consumers. The theory relies on two psychological assumptions. First, customers care about the fairness of prices: fixing the price of a good, consumers enjoy it more at a low markup than at a high markup. Second, customers underinfer marginal costs from prices: wh...
