In this paper we estimate a variable cost function to analyze cost economies and technical change in the English water only sector over the 1995-2005 period. We jointly model the impact on costs of output, customer numbers and area size which allows us to consider both the vertical and...

The aim of this study is to discuss the empirical literature which analyzes the relationship between firms heterogeneity and export activity on Italian manufacturing firm level data. We first present a short review of the main empirical techniques adopted in the applied literature and we briefly...

This paper analyses the impact of port activities on local development for a sample of 621 TL-3 regions located in thirteen European countries and observed over the period 1998–2009. Using a spatial panel econometric framework which controls for spatial fixed effects, the paper provides an...

This paper provides empirical evidence on the relation between the identity of ultimate owners and technical (in)efficiency by estimating stochastic production frontiers on Italian firm level panel data for twelve manufacturing industries over the 1978–93 period. Privately-owned independent...

In this study we analyze the evolution of operating cost efficiency for the English and Welsh water industry over the period 1995-2001 by estimating an heteroskedastic stochastic variable cost frontier. Aim of the paper is to analyze cost efficiency over a period characterized by significant...

In questo lavoro si discutono le possibili implicazioni economiche dei due quesiti referendari del giugno 2011 che hanno interessato il settore idrico italiano e che hanno abolito l’obbligo del ricorso alla gara come modalità standard di affidamento del servizio e il riferimento alla...

In this paper we analyse the cost structure of the UK airport industry by estimating a variable cost function for the period 1994-2005. Overall results suggest that average costs decrease until passenger traffic reaches 5 million, remain constant over the range between 5 million and 14 million...
