The function of communal water supply utilities is to provide consumers with high quality drinking water in sufficient quantities. On the other hand communal wastewater disposal utilities have to dispose the wastewater. In addition to this water prices and wastewater charges shall also give...

In efficiency studies using the stochastic frontier approach, the main focus is to explain inefficiency in terms of … some exogenous variables and computation of marginal effects of each of these determinants. Although inefficiency is … computed from the unconditional mean of inefficiency (Wang, 2002). In this paper we derive the marginal effects based on the …

Heterogeneity among firms has been an important issue in studying firms’ technical efficiencies. If firms do not randomly fall into different groups with different technologies but by self-selection, statistically it implies the data are subject to the sample selection bias. In this paper, we...

The purpose of the paper is to provide new information on the performance of frontier estimation methods, using data from Italian hotel industry. Quantile regression is also suggested as solution to frontier production function estimation. It is shown that, while the choice of estimation methods...

It has been argued that the deterministic frontier approach in inefficiency measurement has a major limitation as … inefficiency is mixed with measurement error (statistical noise) in this approach. The result is that inefficiency is contaminated … captures all other factors other than inefficiency. The stochastic frontier model has been used for inefficiency analysis …

As in Brock and Taylor (2011) in this paper we consider the importance of the relationship between the Environmental Kuznets Curve (EKC) Literature and the Economic Growth Theories. To address this issue we construct country production functions that directly incorporate CO2 emissions as input...

Stochastic production frontiers of irrigated and rain-fed smallholder agriculture in Tigray, Ethiopia, were fitted to a random sample of irrigated and rain-fed plots to compare their technical efficiencies. Propensity Score Matching Method was applied to select rain-fed plots with comparable...

It is well recognized that the production of many farm commodities, especially fruits and vegetables, has become geographically concentrated, with larger but fewer farmers involved in production. This concentration, according to critics, has resulted in the production of less flavorful...
