It is generally believed that companies choose supply chain partners on the basis of their distinctive value propositions – a fact one would also expect holds true when companies choose a logistics service provider. However, faced with the complexities of varied customer demands, it can be...

In this paper we investigate the optimal supply function for a generator who sells electricity into a wholesale electricity spot market and whose profit function is not smooth. In previous work in this area, the generator’s profit function has usually been assumed to be continuously...

Supply function equilibria are used in the analysis of divisible good auctions with a large number of identical objects to be sold or bought. An important example occurs in wholesale electricity markets. Despite the substantial literature on supply function equilibria the existence of a pure...

We model a situation in which a single firm evaluates competing suppliers and selects just one. Suppliers submit bids involving both price and quality variables. The buyer makes a choice which from the supplier's perspective appears to contain a stochastic element - for example the buyer may...

Conditional value at risk (CVaR) has been widely used as a risk measure in finance. When the confidence level of CVaR is set close to 1, the CVaR risk measure approximates the extreme (worst scenario) risk measure. In this paper, we present a quantitative analysis of the relationship between the...

We lay out alternative ways of melding measures of absolute and relative deprivation in an index of overall deprivation, exploring the choices the analyst faces in this enterprise. The indices derived are used to answer two important empirical questions. First, did overall deprivation fall in...
