We study the problem of computing equilibrium prices in a Fisher market with linear utilities and linear single-constraint production units. This setting naturally appears in ad pricing where the sum of the lengths of the displayed ads is constrained not to exceed the available ad space. There are three approaches to solve market equilibrium problems: convex programming, auction-based algorithm...

This paper investigates how incentives of network operators to deviate from neutrality may create social costs or benefits in different market structures. The deviation from network neutrality is a general form of discrimination based on charging different prices for non-affiliated content and application providers. In this paper, deviation from network neutrality is formulated as a form of ver...

The market enthusiasm generated around investment in CRM technology is in stark contrast to the naysaying by many academic and business commentators. This raises an important research question concerning the extent to which companies should continue to invest in building a CRM capability. Drawing on field interviews and a survey of senior executives, the results reveal that a superior CRM capab...

We examine using the Stochastic Grid Bundling Method (SGBM) to price a Bermudan swaption driven by a one-factor LIBOR Market Model (LMM). Using a wellknown approximation formula from the finance literature, we implement SGBM with one basis function and show that it is around six times faster than the equivalent Longstaff–Schwartz method. The two methods agree in price to one basis point, and th...

The paper presents recent developments in Morfeusz – a morphological analyser for Polish. The program, being already a fundamental resource for processing Polish, has been reimplemented with some important changes in the tagset, some new options, added information on proper names, and ability to perform simple prefix derivation. The present version of Morfeusz (including its dictionaries) is ma...
