the purpose of this study is to examine the dynamic effects of some macroeconomic variables: money stock, gross domestic product, consumer price index and exchange rates on determining housing price index behavior in iran using the error correction model. using seasonal data, the model is estimated by johansen-juselius cointegration approach during 1990-2007. the results reveal that all variabl...

Most respondents state that Flow Based market coupling (FB) optimizes the allocation of cross-border capacity, which entails higher social welfare and higher price convergence. Better cooperation between TSOs is also mentioned, since FB forces TSOs and Exchanges to work together. According to most respondents FB will also lead to better transparency regarding critical branches and shadow prices...

The software system ABACUS is an object-oriented framework for the implementation of branch-and-cut and branch-and-price algorithms. This paper describes the design of ABACUS including the design principles and the most important classes.

We model the interaction of several radio devices aiming to obtain wireless connectivity by using a set of base stations (BS) as a non-cooperative game. Each radio device aims to maximize its own spectral efficiency (SE) in two different scenarios: First, we let each player to use a unique BS (BS selection) and second, we let them to simultaneously use several BSs (BS Sharing). In both cases, w...

The paper surveys the price competitiveness of agricultural production in Central and East European Countries (CEECs). It draws together empirical work conducted by the authors and other studies that have estimated domestic resource cost (DRC) ratios for agriculture in various CEECs. The paper identifies that in general CEEC crop production is more internationally competitive than livestock far...

This article focuses on the empirical modeling of advance purchasing and the effects of price on purchasing behavior. Because pricing strategies are typically more complex than simply setting a single price point, the authors consider multiple aspects of price: (a) use of multiple price tiers, (b) face value of tickets, and (c) discounts resulting in week-to-week variations in price. They show ...

We study the problem of finding the minimal initial capital needed in order to hedge without risk a barrier option when the vector of proportions of wealth invested in each risky asset is constraint to lie in a closed convex domain. In the context of a Brownian diffusion model, we provide a PDE characterization of the super-hedging price. This extends the result of Broadie, Cvitanic and Soner (...

Industries are rarely perfectly competitive. They also rarely comprise only firms who transact solely with consumers. Rather, in many industries—including health care, technology, media, and financial markets—firms are oligopolistic and negotiate terms of trade with one another across different market segments. Understanding how firms compete and interact in these vertical markets is critical n...

We analyze a joint inventory and pricing model of a single product over a finite planning horizon with deterministic demand. In this model, an ordering quantity and a price are decided simultaneously at the beginning of each period, demand of the period depends on the price, and a price adjustment cost is incurred if the price is changed from the previous period. We develop polynomial time algo...
