Persistent and transient productive inefficiency in a regulated industry : electricity distribution in New Zealand

Filippini, Massimo ; Greene, William H. ; Masiero, Giuliano

The productive efficiency of a firm can be decomposed into two parts, one persistent and one transient. So far, most of the cost efficiency studies estimated frontier models that provide either the transient or the persistent part of productive efficiency. This distinction seems to be appealing also for regulators. During the last decades, public utilities such as water and electricity have...

Cost efficiency measurement in postal delivery networks

Filippini, Massimo ; Koller, Martin

The purpose of this study is to analyze the level of cost efficiency of Swiss Post’s postal delivery units to enable policy makers’ as well as Swiss Post to decide on the reactions to market changes. In particular, we use different panel data models to assess cost efficiency in these units to account for unobserved heterogeneity. The results from applying Mundlak’s formulation to the...

Economies of scale and efficiency measurement in Switzerland’s nursing homes

Farsi, Mehdi ; Filippini, Massimo ; Lunati, Diego

This paper examines the cost efficiency in the nursing home industry, an issue of concern to Swiss policy makers because of the explosive growth of national expenditure on elderly care and the aging of the population. A stochastic cost frontier model with a translog function has been applied to a balanced panel data of 1780 observations from 356 nursing homes operating over five years (1998-2002)...

Effects of ownership, subsidization and teaching activities on hospital costs in Switzerland

Farsi, Mehdi ; Filippini, Massimo

This paper explores the cost structure of Swiss hospitals, focusing on differences due to teaching activities and those across different ownership and subsidization types. A stochastic total cost frontier with a Cobb-Douglas functional form has been estimated for a panel of 150 general hospitals over the six-year period from 1998 and 2003. Inpatient cases adjusted by DRG cost weights and...

Regulation, ownership and efficiency in the Swiss nursing home industry

Crivelli, Luca ; Filippini, Massimo ; Lunati, Diego

Switzerland is a federal State where policy decisions and implementation regarding long-term care regulation are by rights incumbent to the regional and local governments (Canton and Town Council). This situation is in part responsible for the large number of small nursing homes operating in Switzerland. Moreover, long-term care for the elderly is supplied by private for-profit nursing homes,...

An analysis of efficiency and productivity in Swiss hospitals

Farsi, Mehdi ; Filippini, Massimo

This paper examines the productive efficiency of the hospital sector in Switzerland. A panel data of 214 general hospitals over the four-year period between 1998 and 2001 has been analyzed. A descriptive analysis of the data casts some light on differences across hospital types especially regarding case mix severity and length of hospitalizations. The final sample used for the cost frontier...
