The efficient operation of sewerage services is impacted by various factors such as geographic and topographical conditions, diversity of vertical and horizontal organizational structure, ownership types, and level of public–private partnership. The Ministry of Land, Infrastructure, Transport...

This paper investigates the determinants of profit change over the period 1991-2008 for the Water and Sewerage Companies (WaSCs) in the English and Welsh water and sewerage industry. We firstly apply an input oriented profit decomposition approach following the approach of De Witte & Saal...

The purpose of this paper is to assess the impact of regulation in the financial performance of the Water and Sewerage companies (WaSCs) in England and Wales. We apply a panel index approach across WaSCs over time to decompose unit-specific (temporal) index number based profitability growth as a...

The purpose of this paper is to develop a methodology which can be used to set X-factor under price cap schemes, when the number of observations is limited. We firstly apply a panel index approach across Water and Sewerage companies (WaSCs) over time to decompose unit-specific index number based...

The purpose of this paper is the evaluation of various profit drivers such as price changes, productivity changes and quality levels on the financial performance of the Water and Sewerage Companies (WaSCs) over time in the case when the number of observations is limited. We thereby follow...

A water supply system composed of water production facilities and transmission facilities obtains water from various sources such as surface water, groundwater and so on. Although there are many empirical studies such as measuring efficiency, productivity and/or returns to scale for water supply...

The purpose of this study is to identify the effects of subsidies on the cost structure of Japanese water supply organizations by estimating the translog cost function. Geographical conditions, such as network density and water sources, are also controlled in this model. The empirical results...
