Most applications of chance-constrained programming are based on either normally distributed random variables or random variables with symmetric distributions such as uniform, which can be approximated rather accurately by the normal distribution. In this paper we study pure capital rationing with selection of the best project mix when cash flows and available budget are random variables with asymmetric distributions. We show that solutions obtained by chance-constrained programming using normality approximation for asymmetrically distributed random variables fail to satisfy budget constraints when cash outflows are skewed to the left, indicating that realized cash outflows are more likely to be higher than expected.  相似文献

The possibility, even if arbitrarily small, of binding budget constraints in simultaneous ascending bid auctions induces strategic demand reduction and generates significant inefficiencies. Under mild conditions on the distributions of the bidders' values, unconstrained bidders behave as if they were liquidity constrained, even as the probability that bidders are budget constrained goes to zero.  相似文献

It is usually acknowledged that firms benefit from a large customer base in markets with switching costs. However, Klemperer [1995] argues that this may not be true if an increase in the size of a firm's customer base induces fierce price competition, making the firm worse off. This paper shows that such an outcome can be obtained under standard assumptions, such as homogeneous goods and uniformly distributed switching costs. In the model, firms have very limited incentives to fight for market shares, and the notion that switching costs make markets less competitive is stronger than previously shown.  相似文献
