We investigate the effect of sequential commitment in the decentralized newsvendor model with price-dependent demand. Sequential commitment allows the self-profit maximizing parties to commit to contract parameters (e.g., wholesale price, retail price, buyback price and order quantity) sequentially and alternately, and we investigate its effect on the equilibrium profits of the channel and its ...

In wireless network convergence, eachmobile host is expected to havemultiple kinds of wireless interfaces.Multicast-based applications are expected to be widely deployed. In this paper, a new network selection scheme is proposed for a mobile host to select the most appropriate wireless access network to maximize user satisfaction and ISP’s profit, simultaneously. We have devised a metric to mea...

We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables that are independent of each other and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period and all shortage...

Our aim is to maximize expected profit per item of a multi-stage production system by determining best adjustment points of the equipments used based on technical product specifications defined by designer. In this system, the quality characteristics of items produced should be within lower and higher tolerance limits. When a quality characteristic of an item either falls beneath the lower limi...

I this paper we propose an incentive payment contract for stochastic projects defined by a series of stages or tasks that are outsourced to independent subcontractors. Projects defined by sequentially completed independent stages are common in new product development and other high-risk projects. Our goal is to maximize the client’s expected discounted profit. Our proposed contract reflects the...

Price coordination can be very harmful for consumers. Yet, even if a cartel is proved to exist, and successful in enforcement, how do we estimate damages or price overcharges to consumers? We build a structural model of the Irish automobile market that avails of a crosssection of new cars and jointly estimate demand and cost primitives. We use these estimates to quantify the role that price coo...

We investigate the relationship between pay, supervision and employee sharing. Our results suggest an inverse relationship between supervision and pay across both sharing and non-sharing firms, although the trade-off is somewhat assuaged within the former. This would appear to contradict instrumental efficiency wage considerations, but could be rationalised within a gift-exchange context. In te...

This paper examines risk-averse and risk-seeking investor preferences for oil spot and futures prices by using the mean-variance (MV) criterion and stochastic dominance (SD) approach. The MV findings cannot distinguish between the preferences of spot and futures markets. However, the SD tests show that spot dominates futures in the downside risk, while futures dominate spot in the upside profit...

This paper considers a repairable system with a repairman, who can take multiple vacations. If the system fails and the repairman is on vacation, it will wait for repair until the repairman is available. Assume that the system cannot be repaired ‘‘as good as new’’ after failures. Under these assumptions, using the geometric process and the supplementary variable technique, some important reliab...

We analyze an infinite horizon, single-product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables that are independent of each other, and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period, and all shorta...
