The economic performance of Swiss drinking water utilities

Faust, Anne-Kathrin ; Baranzini, Andrea

In: Journal of productivity analysis, 2014, vol. 41, no. 3, p. 383-397

This paper measures the performance in terms of costs of Swiss drinking water utilities accounting for environmental factors. We estimate a translog stochastic variable cost frontier using two different techniques on an unbalanced panel of 141 water distribution utilities over the years 2002–2009, for a total of 745 observations. Results show that exogenous factors have an impact on variable...

Tropical forest conservation : attitudes and preferences

Baranzini, Andrea ; Faust, Anne-Kathrin ; Huberman, David

In: Forest policy and economics, 2010, vol. 12, no. 5, p. 370-376

This paper applies contingent valuation to assess public awareness of tropical deforestation, to investigate the willingness to pay (WTP) to conserve tropical forests, and to determine the impact of the payment vehicle on the stated WTP of a sample of about 500 individuals in Geneva, Switzerland. About ¾ of respondents state that they have already heard about tropical deforestation and...

The cost structure of water utilities in Switzerland

Baranzini, Andrea ; Faust, Anne-Kathrin

This paper estimates a translog cost function for Swiss water utilities. From the cost function, we are able to estimate measures of marginal costs as well as economies of production density, customer density and scale, which are important determinants in water policies, such as planning and water tariffs. In order to explore the determinants of water supply costs, their structure and...

Water supply : costs and performance of water utilities : evidence from Switzerland

Baranzini, Andrea ; Faust, Anne-Kathrin ; Maradan, David

In this paper, we assess the economic efficiency of Swiss water utilities. To reach this aim, we accessed a new and unexploited database, which counts 330 water utilities, representing about 55% of the drinking water distributed in Switzerland. The database spans over six years (2000-2005) and offers information on the type of the water production process, the characteristics of the network and...

Tropical forest conservation : attitudes and preferences : cahier de recherche

Baranzini, Andrea ; Faust, Anne-Kathrin ; Huberman, David

This paper applies contingent valuation to assess public awareness of tropical deforestation; to investigate the willingness to pay (WTP) to conserve tropical forests; and to determine the impact of the payment vehicle on the stated willingness to pay. About ¾ of respondents state that they have already heard about tropical deforestation and biodiversity. People rank carbon storage as the most...
