This paper analyzes price elasticities in the Austrian market for mobile telecommunications services using data on firm specific tariffs. Both static and a dynamic panel data approaches lead to consistent results which provide evidence for a relatively elastic demand. Furthermore, some basic facts on the Austrian mobile telephone sector are presented. JEL-Classification: C23, L13, L96.

estimation of agricultural sector demand and supply and identification of its determinants could lead to more efficient policies and planning of this section. in this study, aggregate demand and supply of agriculture sector for years of 1959-2007 by using of nonlinear restricted armax model are estimated. result indicates that aggregate agriculture demand is inelastic in short and long run. tho...

fuzzy controllers are being used in various control schemes. the aim of this work was adjusting hemodialysis machine parameters utilizing a fuzzy logic controller (flc) so that patient’s hemodynamic condition remains stable during hemodialysis treatment. for this purpose a comprehensive mathematical model of the arterial pressure response during hemodialysis, including hemodynamic, osmotic, and...

Game theoretic approaches to the study of electricity markets have been explored for decades [2], [7], [10]. Recently problems associated with variations of the optimal power flow problem with static (inelastic) demand for an electrical power grid [5], [21], [22], have been considered by several authors, e.g., [15], [17]. Indeed, demand elasticity for electricity is motivated by the onset of po...

A quantized progressive second price auction mechanism called ADQ-PSP is presented which improves upon the performance of the so-called Q-PSP mechanism presented in (Qu, Jia & Caines 2007, Jia, Qu & Caines 2008). The Q-PSP mechanism was developed for the fast convergence properties that can be proven for it subject to the assumption that all agents (i.e. buyers) share similar demand (i.e. margi...

We examine competition in the hospital industry, in particular the effect of ownership type (for-profit, not-for-profit, government). We estimate a structural model of demand and pricing in the hospital industry in California, then use the estimates to simulate the effect of a merger. California hospitals in 1995 face an average price elasticity of demand of -4.85. Not-for-profit hospitals face...

p olicy makers in housing sector seeks to use instruments by which they can control volatility of housing price and prevent high disturbances of the bubble and price shocks, or at least, reduce them. in the portfolio and speculation theories, it is emphasized that speculative demand for housing is the main cause of shocks and price volatilities in the sector. the theory of housing price bubble ...
