Innocent people who have been arrested, but never convicted of a crime, will have their DNA records stored on the national database for a period of six years under plans unveiled in the government’s new Crime and Security Bill. The Bill, presented to parliament by Home Secretary Alan Johnson on 19 November 2009, also includes a number of new rules for the collection, retention and use of DNA an...

Hansen and Jagannathan (1997) have developed two measures of pricing errors for asset pricing models: the maximum pricing error in all static portfolios of the test assets and the maximum pricing error in all contingent claims of the assets. In this paper, we develop simulation-based Bayesian inference for these measures. While the literature reports that the time-varying extensions substantial...

We study dynamic pricing policies for a monopolist selling perishable products over a finite time horizon to buyers who are strategic. Buyers are strategic in the sense that they anticipate the firm’s pricing policies. We are interested in situations in which auctions are not feasible and in which it is costly to change prices. We begin by showing that unless strategic buyers expect shortages d...

In this paper, we aim at developing a model for option pricing to reduce the risks associated with Ethiopian commodity prices fluctuations. We used the daily closed Unwashed Lekempti grade 5 (ULK5) coffee and Whitish Wollega Sesame Seed Grade3 (WWSS3) prices obtained from Ethiopia commodity exchange (ECX) market to analyse the prices fluctuations.The natures of log-returns of the prices exhibit a...

Futures contract is one of the most important derivatives that is used in financial markets in all over the world to buy or sell an asset or commodity in the future. Pricing of this tool depends on expected price of asset or commodity at the maturity date. According to this, theoretical futures pricing models try to find this expected price in order to use in the futures contract. So in this ar...

One of the key issues for implementing congestion pricing is the pricing granularity (i.e. pricing interval or time-scale). The Internet traffic is highly variant and hard to control without a mechanism that operates on very low time-scales, i.e. on the order of round-trip-times (RTTs). However, pricing naturally operates on very large time-scales because of human involvement. Moreover, structu...

Data as a commodity has always been purchased and sold. Recently, web services that are data marketplaces have emerged that match data buyers with data sellers. So far there are no guidelines how to price queries against a database. We consider the recently proposed query-based pricing framework of Koutris et al. [13] and ask the question of computing optimal input prices in this framework by f...

The sports industry has seen a rapid adoption of dynamic pricing practices in recent years. However, there is still limited understanding on the effect of dynamic pricing on revenue in sport event settings and how to execute effective dynamic pricing strategies. In this paper, we address these issues by developing a comprehensive demand model for single-game ticket sales that can be used to pre...
