Deriving a functional form for a series of prices over time is difficult. It is common to assume some linearly estimable form for prediction purposes. While this can produce accurate short run forecasts it fails to identify longer trends and patterns that may exist in financial data....

If the creditworthiness of a counterparty is a derivative of a commodity price, there is the potential to have right- or wrong-way exposures in respective commodity transaction. Identifying them is important, because otherwise credit costs might be inadequately calculated and wrong incentives...

The Democratic Republic of the Congo represents one of the world's most important sites for mining activities. Strategic raw materials, such as cobalt and tantalum, fuel the global electromobility movement and high-tech industries. Located in the heart of Africa multinational firms from Canada,...

Many policy-makers are currently weighing the advantages of deregulating electricity markets over more traditional regulatory methods. However, within this traditional regulatory environment many options exist. In particular, the use of incentive regulation programs in US electricity markets has...

Electricity and natural gas markets have traditionally been serviced by one of two market structures. In some markets, electricity and natural gas are sold by a dual-product regulated monopolist, while in other markets, electricity and natural gas are sold by separate single-product regulated...

While the Telecommunications Act of 1996 introduces competition into local telephone markets at a national level, prior to the Act many states had already restructured their regulatory methods. In particular, many states allowed for competition in both local service and "local long distance"...

Aggregate demand models typically assume that consumers choose between all available products. Since consumers may be unwilling to search across every store in a given market for a particular item, this assumption is problematic when product assortments vary across stores. Using supermarket...

Internet auctions have recently gained widespread popularity and are one of the most successful forms of electronic commerce. We examine a dataset of eBay coin auctions to explore features of online bidding and selling behavior. We find that profit margins for bidders are slim on average, that...

Standard discrete choice models such as logit, nested logit, and random coefficients models place very strong restrictions on how unobservable product space increases with the number of products. We argue (and show with Monte Carlo experiments) that these restrictions can lead to biased...
