摘要：We conceptualize participation in Linux user groups (LUGs) in terms of group-referent intentional actions and investigate cognitive (attitudes, perceived behavioral control, identification with the open source movement), affective (positive and negative anticipated emotions), and social (social identity) determinants of participation and its consequences on Linux-related behaviors of users. This survey-based study, conducted with 402 active LUG members representing 191 different LUGs from 23 c...

摘要：This study formalizes the departure between risk-neutral and physical index return volatilities, termed volatility spreads. Theoretically, the departure between risk-neutral and physical index volatility is connected to the higher-order physical return moments and the parameters of the pricing kernel process. This theory predicts positive volatility spreads when investors are risk averse, and when the physical index distribution is negatively skewed and leptokurtic. Our empirical evidence is s...

摘要：Pricing and quantity decisions are critical to many firms across different industries. We study the joint price/quantity newsvendor model where only a single quantity and price decision is made, such as a fashion or holiday product that cannot be replenished and where the price is advertised nationally and cannot be changed. Demand is uncertain and sensitive to price. We develop a method for easily finding the optimal price and quantity that applies to more general cases than the usual one in ...

摘要：We propose a method for determining how much to charge users of a communication network when they share bandwidth. Our approach can be employed either when a network owner wishes to sell bandwidth for a specified period of time to a number of different users, or when users cooperate to build a network to be shared among themselves. Our proposed contract and balancing mechanism can mediate between rapidly fluctuating prices and the longer time scales over which bandwidth contracts may be traded...
