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.

Cuticular hydrocarbons from the ponerine ant Ectatomma ruidum Roger and a highly integrated eucharitid myrmecophile, Kapala sulcifacies (Cameron), associated with it, have been characterized. Ninety hydrocarbons were identiÞed from the ant, 55 hydrocarbons from the female wasp and 54 hydrocarbons from the male wasp. The wasps and ants share 40 hydrocarbons. These shared 40 hydrocarbons represen...

We determine under which conditions three bivariate copulas C12, C13 and C23 are compatible, viz. they are the bivariate marginals of the same trivariate copula C̃, and, then, construct the class of these copulas. In particular, the upper and lower bounds for this class of trivariate copulas are determined.

We use a panel of 155 countries for 1970-2010 to study (two-way) causality between government spending, revenue and growth. Our results suggest the existence of weak evidence supporting causality from expenditures or revenues to GDP per capita and provide evidence supporting Wagner’s Law. JEL: C23, E62, H50.

The ability of rat liver microsomes to catalyze UDP-glucuronic acid-dependent glucuronidation of monohydroxy-bile acids was examined. The following bile acids were used as substrates, each as the 3 alpha and 3 beta epimer: 3-hydroxy-5 beta-cholanoic acid (C24), 3-hydroxy-5 beta-norcholanoic acid (C23), 3-hydroxy-5 beta-bisnorcholanoic acid (C22), 3-hydroxy-5 beta-pregnan-21-oic acid (C21), and ...

This paper derives consistent standard errors for a panel Tobit model in the presence of correlated errors. The problem is framed in the context of Newey and West (1987), considering the Tobit model as a special case of a GMM estimator. JEL codes: C23, C24

We estimate the political economy determinants of budget deficit forecast errors. Since the adoption of the Stability Pact, Eurozone governments have manipulated forecasts before elections. The political orientation and the institutional design of governments also affects the quality of forecasts. JEL classifications: H62, H87, C23, C53, E62
