At each point in time, price dynamics in a market are determined by a market for access to trading partners, implemented by competitive profitmaximizing brokers. This mechanism is applied to a market in which the value of a good declines over time and buyers decide optimally when to reenter the market and buy a new unit. Price adjustment paths in response to increases and decreases in demand ar...

The Digital Water Education Library collection (DWEL) is being generated by primary and secondary school teachers in the United States. This complex process involves both individual research and team design, and the use of a variety of online tools, such as an online cataloguing tool. Interactions amongst DWEL members are being ethnographically analysed in order to identify requirements for fur...

The article investigates the Swedish retail banks’ application of price bundling in order to attract new customers, students. This is done through a customer survey about students’ preferences concerning retail banking services, their price sensitiveness and banking behaviour. The conjoint analysis results showed that the students had relatively heterogeneous preferences, and four distinguishin...

The struggle of poor women and men in developing countries to ensure sufficient nutritious food for their families has been regularly reported in the media in Northern and Southern countries over the past four years. The global food price spikes have increased undernourishment by almost seven percent, and have driven at least 100 million more people into poverty. By 2050, the world population w...

Auctions with variable supply are multi-unit auctions, in which the seller determines the supply quantity as a function of the bidding. These auctions are used on various markets ranging from Treasury bills and IPOs to rare wine and art. In this work we compare in a common value model the mixed strategy subgame perfect equilibria and the rationalizable strategies of the uniform price and the di...

Cerebral ischemic stroke is a major reason for death in Germany and worldwide. Although lots of research has been done on longtime (3 hrs – 27 days) stroke growth, not much is known about the acute stroke growth. In this paper a method for the image based analysis and visualization of short-time infarct growth in murine model based on time resolved T2* MR image sequences is presented. After man...

A common feature of low-price guarantees is that they allow consumers to postpone bargain-hunting until after the purchase. This paper addresses a number of questions concerning the adoption pattern of price-matching and price-beating guarantees with post-purchase search and their impacts on market prices. It is shown that low-price guarantees are offered by low-cost firms, and are associated w...

We model cheating in second price auctions when valuations of bidders are affiliated. Bidders predict cheating behavior by an unfair seller who can observe the bids submitted by all bidders and then submits his extra bid to increase the payment of the winning bidder. We derive a symmetric equilibrium strategy in the cheating model. Moreover, we conduct a numerical analysis to compare a second p...

Our submission guesses at entailment based on word similarity between the hypotheses and the text. We attempt three kinds of comparisions: original words (with normalized dates and numbers) synonyms, and antonyms. Each of the three comparisions contributes a different weight to the entailment decision. Our results are insignificantly better than chance for the two-way comparison. However, for t...
