Interconnecting distinct electricity markets by adding a new transmission line affects the outcomes in these markets in a complicated way when there is uncertainty in demand or participant behaviour. We use market distribution functions to examine the effects of interconnection using a single...

Recent data suggest that the fortunes of unskilled workers in developed countries improved during the 1990s, after deteriorating significantly during the 1980s. Such a trend could be explained by a faster decline in the relative supply of unskilled labour, a slower decline in the relative demand...

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...

This paper uses a gravity model to examine the effect of time differences between countries on international trade. It builds on previous studies of this issue by including a wider set of control variables, focusing on a longer time period, and testing a series of related hypotheses. The results...

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...
