We consider a newsvendor who makes an ordering decision to meet stochastic demand and buys a put option written on the demand to hedge against the risk of low demand to maximize his expected utility, which is measured by the conditional value-at-risk (CVaR). The put option is fairly priced with...

This paper studies the group-buying mechanism from a dynamic perspective. We consider a seller that offers a product in the form of group buying (priced low but uncertain) and spot purchasing (priced high but guaranteed). In the case of group buying, the information associated with the number of...

The influence of corporate social performance (CSP) on stakeholders is one of the focal issues in corporate social responsibility (CSR) research. Using data of listed companies in China, this paper examines whether CSR behavior in the form of charitable donations garners a positive reaction from...

The pricing issue of supply chain options is generally considered in the Stackelberg game framework in the literature. Such a pricing scheme, however, is usually unacceptable to the follower in the game since it serves only the leader's interest. Different from the existing literature, we...

A fashion supply chain characterized by a long lead time and a short selling season is considered in this paper. Facing demand uncertainty, the risk averse retailer has two opportunities to make order decisions before the demand is realized. The risk aversion is modelled as a penalty to the...

In this paper we develop a supply contract for a two-echelon manufacturer–retailer supply chain with a bidirectional option, which may be exercised as either a call option or a put option. Under the bidirectional option contract, we derive closed-form expressions for the retailer’s optimal...

Three groups of hydrate-bearing sediment samples with/without underlying gas were prepared using a three-dimensional middle-size reactor to investigate the favorable conditions for methane recovery from hydrate reservoir with gaseous CO2. The experimental results indicated that hydrate reservoir...

For inequality constrained optimization problem, we show the existence of local saddle point of generalized augmented Lagrangian under weak second-order sufficient conditions which are weaker than the second-order sufficient conditions in the literature. We further discuss the existence of...

Natural gas hydrates are cage-like crystalline compounds in which a large amount of methane is trapped within a crystal structure of water, forming solids at low temperature and high pressure. Natural gas hydrates are widely distributed in permafrost regions and offshore. It is estimated that...
