⎯In many industries, sellers have the opportunity to enhance their revenues through the dynamic pricing of their perishable products such as flight seats, hotel rooms, or seasonal fashion goods that become worthless if they are not sold by a specific time. Therefore, how to dynamically adjust the prices of perishable products through differentiating the purchased time and the amount of unsold i...

This paper investigates and compares airport pricing policies under various types of competition, considering both per-passenger and per-flight charges at congested airports. We show that an airport requires both pricing instruments to achieve the first-best outcome, and we distinguish their role by showing that congestion externalities need to be addressed through per-flight tolls whereas the ...

As is well recognized, market dominance is a typical outcome in markets with network effects. A firm with a larger installed base offers a more attractive product which induces more consumers to buy its product which produces a yet bigger installed base advantage. Such a setting is investigated here but with the main difference that firms have the option of making their products compatible. Whe...

Pricing has turned into a highly significant matter for suppliers and their customers since deregulation has been realized in the electrical industry and many countries have revised the structure of their electrical energy market by defining different competition levels in generation, transmission and distribution. In the current paper, a proposed algorithm based on games theory has been used f...

This paper studies (1) whether, from a welfare point of view, oligopolistic competition leads to too few or too many products in a market, and (2) how a change in competition affects the number and the composition of product offerings. We address these two questions in the context of the U.S. smartphone market. Our findings show that this market contains too few products and that a reduction in...

We present a matching-pricing algorithm for online information labor markets motivated by exploratory study of Amazon Mechanical Turk (AMT). The algorithm addresses many of the challenges surfaced by the AMT study. We find that AMT pricing is largely done using rules of thumb, which results in inaccurate pricing. Such pricing leads to either excessive costs for employers or low income for worke...

In the information age, the availability of data on consumer profiles has opened new possibilities for companies to increase their revenue via data mining techniques. One approach has been to strategically set prices of various products, taking into account the profiles of consumers. We study algorithms for the multi-product pricing problem, where, given consumer preferences among products, the...

a r t i c l e i n f o Keywords: Multivariate GARCH model Optimal hedge ratio Market noise conditional volatility This paper introduces a new incomplete index and establishes a new optimal hedging model. We find that when the market micro-noise is perfectly negatively correlated with the return of futures market, market incomplete-ness depends on the relative level of noise volatility. Especiall...

This paper investigates the pricing of differentiated products in a vertical sector, with a focus on the role of industry concentration. We propose concentration indices that extend the classical Hirschman-Herfindahl Index (HHI) to include vertical structures that manage differentiated products. We also identify how substitution/complementarity among products affects pricing. We compare our pro...
