We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers competing in quantities. We study analytically the supply chain with symmetric retailers and find that the supplier generally prefers to have as many retailers as possible in the market, even if the retailers’ equilibri...

We consider three models of investments in generation capacity in restructured electricity systems that differ by their underlying economic assumptions. The first model assumes a perfect, competitive equilibrium. It is very similar to the old capacity expansion models even if its economic interpretation is different. The second model (open-loop Cournot game) extends the Cournot model to include...

Numerous investigations have been directed toward aspects of rational life insurance purch&es and optimal coverage levels under differing conditions. Most of these studies have taken as "given" the design of life insurance contracts and have focused on optimal consumer responses to available insurance opportunities.' However, in works by Borch (1960, 1983), Arrow (1963, 1974) and Raviv (1979), ...

In this paper, Black Scholes’s pricing model was developed to study American option on future contracts of Brent oil. The practical tests of the model show that market priced option contracts as future contracts less than what model did, which mostly represent option contracts with price rather than without price. Moreover, it suggests call option rather than put option. Using t hypothesis test...

The dynamics of sales opportunities can be modelled by a Markov Decision Process. The latter can be solved using dynamic programming and assigns to each state an optimal action. In this project, states are modelled by the number of opportunities at five different maturity levels called ranks, actions are represented by investments and rewards by profits from signed contracts. Transitions are si...

We consider a manufacturer selling to a retailer with private demand information arising dynamically over an infinite time horizon. Under a backlogging model, we show that the manufacturer’s optimal dynamic long-term contract takes a simple form: in the first period, based on her private demand forecast, the retailer selects a wholesale price and pays an associated upfront fee, and, from then o...

Field service is gaining importance as after sales service is starting to be recognized as a major source of revenue. This motivates planning problems for companies that employ mobile technicians who provide service on clients’ sites. These planning problems share the common characteristic that service levels corresponding to technician response times are explicitly expressed in contracts. More...

In this paper, we provide a detailed characterization of the return volatility in US Treasury bond futures contracts using a sample of 5-min returns from 1994 to 1997. We find that public information in the form of regularly scheduled macroeconomic announcements is an important source of volatility at the intraday level. Among the various announcements, we identify the Humphrey–Hawkins testimon...

In product line engineering various stakeholders like sales and marketing people, product managers, and technical writers are involved in creating and adapting documents such as offers, contracts, commercial conditions, technical documents, or user manuals. In practice stakeholders often need to adapt these documents manually during product derivation. This adaptation is, however, tedious and e...
