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.

We show that the quantile regression estimator is consistent and asymptotically normal when the error terms are correlated within clusters but independent across clusters. A consistent estimator of the covariance matrix of the asymptotic distribution is provided and we propose a specification test capable of detecting the presence of intra-cluster correlation. A small simulation study illustrat...

This paper uses player/match level data drawn from five playing seasons of the English Premiership League (EPL) to test for the presence of a refereeing susceptibility to social pressure in the application of soccer’s commonest sanction, the yellow disciplinary card. Using both player-specific fixed and random effects models, tentative support for the proposition is uncovered. The estimated eff...

We analyse the effect of the anonymisation method multiplicative stochastic noise on the within estimation of a linear panel model. In particular, we concentrate on the panel model with serially correlated regressors. In addition to anonymisation as such, the serial correlation in a data set with only few points in time increases the bias of the within estimator and therefore must be taken into...

Cross sectional estimation of convergence regressions is known to be hazardous if there is convergence towards heterogeneous steady state values. In this paper, Monte Carlo methods are used to investigate the implications of this parameter heterogeneity problem. The cross sectional and pooled OLS estimators are compared with a panel estimator which is unaffected by heterogeneity. If there is he...

We suggest moment estimators for the parameters of a continuous time GARCH(1,1) process based on equally spaced observations. Using the fact that the increments of the COGARCH(1,1) process are ergodic, the resulting estimators are consistent. We investigate the quality of our estimators in a simulation study based on the compound Poisson driven COGARCH model. The estimated volatility with corre...

In this paper, we examine the specification tests which have been proposed for fixed effects in binary panel data model, using several different data generating processes to evaluate the performance of the specification test in different situations. By simulations, we find the specification test based on moment conditions is able to outperform the Lagrange multiplier test proposed by Gurmu (199...

This study examines the effects of taxes on the real exchange rate through their marginal impacts on economic activity. We develop a model that shows that an increase in the capital interest tax rate leads to real domestic currency depreciation while an increase in wage or consumption tax rates lead to a real domestic currency appreciation. These theoretical findings are supported by an empiric...

We consider a bivariate Poisson model that is based on the lognormal heterogeneity model. Two recent applications have used this model. We suggest that the correlation estimated in their model frameworks is an ambiguous measure of the correlation of the variables of interest, and may substantially overstate it. We conclude with a detailed application of the proposed method using the data employ...
