The demand for international telephone calls in Australia is comprised of three s ervices with three distinct prices. In order to estimate elasticities for both tariffs and surcharges, an econometric model is developed t hat has two submodels, each of which consists of an aggregate equatio n and...

Eliminating negative end-use or appliance-consumption estimates and incorporating direct-metering information into the process of generating these estimates--these are two important aspects of conditional demand analysis that will be the focus of this paper. In both cases, a Bayesian approach...

The separate identification of effects due to incentives, selection and preference heterogeneity in insurance markets is the topic of much debate. In this paper, we investigate the presence and variation in moral hazard across health care procedures. The key motivating hypothesis is the...

Econometric analysis of the skew of price change distributions for an eighty industry sample over an eleven year period indicates that the distributions are less skewed in times of rapidly changing prices, in concentrated oligopolies, and in markets with little product heterogeneity. The results...

A large proportion of the world telecommunications market can be characterized as supply restricted. In ITU (1999) official waiting lists numbered about 50 million worldwide with an average waiting time of two years. More than 100 countries had not eliminated the waiting list for telephone...

The theoretical and empirical implications of omitted variables, particularly dynamic adjustment effects, are studied. In particular, the attempt to model for such omission by including possibly irrelevant variables is investigated. This extends the existing knowledge of misspecification...
