The Internet has radically reduced the cost of collecting and distributing information. Consequently, researchers initially predicted that the resulting price transparency would drive prices toward a single market price. However, this has largely not happened, partly because retailers use shipping costs to make prices less comparable. Using data on 517,048 offers of 895 retailers from a leading...

In a mature water market with many active buyers and sellers and with a free flow of information about supply, demand and prices paid, prices should not vary greatly at any given time. Willing buyers should always be prepared to pay the going price set by the most efficient and highest value producing irrigators. This paper will analyse the prices paid in two water markets in Australia and iden...

The goal of present experiments is to investigate the use of multiple kernel learning as a tool for pricing options in the context of Indian stock market for Nifty index options. In this paper, fair price of an option is predicted by Multiple Kernel Support Vector Regression (MKLSVR) using linear combinations of kernels and Single Kernel Support Vector Regression (SKSVR). Prices of option highl...

The electricity market in Portugal was recently opened to all consumers. However, it remains highly concentrated in terms of control of production and supply and the long-term power purchase arrangements still coexist with free market. This paper discusses the electricity market restructuring process in Portugal, presenting its main marks over the past years and the present situation. The evolu...

We present a model in which the microstructure of trade in a commodity or asset is endogenously determined. Producers and consumers of a commodity (or buyers and sellers of an asset) who wish to trade can choose between two competing types of intermediaries: “middlemen” (dealer/brokers) and “market makers” (specialists). Market makers post publicly observable bid and ask prices, whereas the pri...

AlgaeSim, a dynamic multiple-systems (C, N, P) mass balance model, was developed to explore the potential for algae biomass production from wastewater by coupling two photobioreactors into the main treatment train at a municipal wastewater resource recovery facility (WRRF) in Tampa, Florida. The scoping model examined the synergy between algae cultivation and wastewater treatment through algal ...

The critical period of weed control (CPWC) in crops depends on many factors including supply and availability of nutrients. In order to investigate the effect of starter fertilizer on the CPWC in soybean a field experiment in a randomized complete block design with four replications in a factorial arrangement was conducted at the Agricultural Research Farm of Razi University, Kermanshah, Iran. ...

Vertical separation of generation from electricity retailing has often been required as a condition of electricity market liberalisation. A well-developed and liquid contracts market is similarly suggested as necessary to manage the resulting wholesale market risks, which risks are further exacerbated by competition. Such contracts markets are rare, however, and increasingly evidence is emergin...

Controlling health care costs requires that limits be placed either on prices, quantities of services, or both. Prices are measurable and more easily controlled than is quantity and, consequently, health care cost containment has frequently focused on mechanisms for controlling prices. Regulatory approaches, however, may create market distortions and change access patterns. An alternative appro...
