In this paper we assess the relative effectiveness of user charges and administrative waiting times as a tool for rationing public healthcare in Italy. We measure demand elasticities by estimating a simultaneous equation model of GP primary care visits, public specialist consultations and...

Voice over Internet Protocol (VoIP) such as Skype that enables users to make free internet-based calls to other users has been seen as a threat to voice revenues by traditional network operators. While some mobile network operators (MNOs) attempt to block Skype's entry on their networks, some...

In this paper we build a simple three-country model to evaluate the impact of "call-back" on international telephony. The effects on both accounting rates and collection prices are studied. Call-back firms exploit arbitrage opportunities in collection prices among countries, rerouteing calls...

The aim of this paper is to study different regulatory effects on termination charges and social welfare. We employ a framework with a fixed network and two mobile networks competing in a market to study the following regulatory regimes: collusive and social welfaremaximising reciprocity,...

This paper studies the endogenous determination of the nature of telephone calls, namely whether they are local or long distance. Calls between users in the same local calling area are local, and we allow the extension of this area to be treated as a strategic variable. We show that the...

This paper develops the CCAPM model to allow for long-run risk in durable consumption. Allowing Epstein-Zin preferences to incorporate non-separability of durable and non-durable consumption in utility provides for an Euler equation which can be shown to provide a much better explanation of...

The price of aggregate risk in the UK appears to have risen significantly since the start of the financial crisis and the associated extended recession. This paper examines the relationship between the business cycle and equity market returns to see how robust this association is. Several...

This study develops a discrete multiple state duration model that al- lows for duration dependence, unmeasured heterogeneity, partial observ- ability of the state and endogenous time-varying treatment. Our econo- metric strategy has numerous potential empirical applications. We apply our...

The discernment of relevant factors driving health care utilization constitutes one important research topic in Health Economics. This issue is frequently addressed through specification of regression models for health care use (y – often measured by number of doctor visits) including, among...
