Production data from 11 southeastern Montana ranches were used to parameterize a bio-economic computer model of cow/calf range production. Effects of changes in breeding date, weaning date, and range removal date on system performance for a ranch with a fixed forage resource base (3,060 animal unit months of range forage and 744 t of hay) were simulated. Input costs were locally established in ...

This article outlines the economic feasibility of mobile operators that combine nationwide mobility with 3G networks and hot spot coverage with WLANS. WLANs are based on HIPERLAN/2 architecture and the UMTS network exploits WCDMA/FDD technology. The evaluated business scenarios are focused on two different deployment areas, in terms of demographic characteristics and mobile penetration: a large...

Carbon tax regulation and consumers' low-carbon preference act as incentives for firms to abate emissions. Manufacturers can improve product sustainability and retailers can strengthen the promotion of low-carbon products as part of such abatement. Current incomplete rationality also affects product sustainability and low-carbon promotion level. In this context, we consider a supply chain with ...

To make informed forecasting and replenishment decisions, many companies bring together operational elements of production and distribution with sales and marketing, executing Sales and Operations Planning (S&OP) collaborative improvement processes. As cross-functional and consensus-based processes, S&OP activities create value by keeping supply and demand in balance. But most S&OP arrangements...

this study examines the responsible energy consumption of listed european hotels. hotel efficiency is estimated using a stochastic frontier analysis (sfa) production function, with supplies costs as the input and total revenue as the output. cluster analysis is used to group the hotels into homogeneous groups according to their efficiency level, size, or profitability. the results show that the...

We study how interactions between financing and investment decisions can shape firm boundaries in dynamic product markets. In particular, we model a new product market opportunity as a growth option and ask whether it is best exploited by a large incumbent firm (Integration) or by a separate, specialized firm (Non-Integration). Starting from a standard theoretical framework, in which value-maxi...

When an innovative product is introduced into the market, consumers are often uncertain about the product value. Over time they may learn the value of product. This paper studies the impact of consumer learning on the firms' marketing efforts and revenue sharing strategies in a supply chain that sells an innovative product to consumers over multiple periods. Both the supplier and the retailer c...

This study examines the incentives for content contribution in social media. we propose that exposure and reputation are the major incentives for contributors. Besides, as more and more social media web sites offer advertising-revenue sharing with some of their contributors, shared revenue provides an extra incentive for contributors who have joined revenue-sharing programs. we develop a dynami...

Predictive pricing (e.g., Google’s “Smart Pricing” and Yahoo’s “Quality-Based Pricing”) and revenue sharing are two important tools that online advertising networks can use in order to attract content publishers and advertisers. We develop a simple model of the pay-per-click advertising market to study the market effects of these tools. We then present an algorithm, PricingPolicy, for computing...
