The impact of ambient air pollution on hospital admissions

Filippini, Massimo ; Masiero, Giuliano ; Steinbach, Sandro

In: European Journal of Health Economics

Ambient air pollution is the environmental factor with the most significant impact on human health. Several epidemiological studies provide evidence for an association between ambient air pollution and human health. However, the recent economic literature has challenged the identification strategy used in these studies. This paper contributes to the ongoing discussion by investigating the...

Habits and rational behavior in residential electricity demand

Filippini, Massimo ; Hirl, Bettina ; Masiero, Giuliano

In: Resource and Energy Economics, 2018, vol. 52, p. 137-152

Households make an investment analysis when buying new electrical appliances. Therefore, expectations about future electricity consumption may have an impact on current consumption and investment decisions. Dynamic partial adjustment models of residential electricity demand neglect rational consumer behavior. In this paper we propose a model for residential electricity demand that allows for...

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...

Rational habits in residential electricity demand

Filippini, Massimo ; Hirl, Bettina ; Masiero, Giuliano

Dynamic partial adjustment models of residential electricity demand account for the fact that households may not adjust electricity consumption immediately in response to changes in prices, income, and other relevant factors, because of behavioral habits or adjustment costs for the capital stock of appliances. However, forward-looking behavior is generally neglected. Expectations about future...

Competitive tendering versus performance-based negotiation in Swiss public transport

Filippini, Massimo ; Koller, Michael ; Masiero, Giuliano

In: Transportation research part A: policy and practice, 2015, vol. 82, p. 158-168

The purpose of this study is to assess differences in the levels of cost efficiency of bus lines operated under competitively tendered contracts and performance-based negotiated contracts. Following the revision of the Swiss railways act in 1996, regional public authorities were given the choice between two different contractual regimes to procure public passenger transport services. We...

Structural and managerial cost differences in nonprofit nursing homes

Di Giorgio, Laura ; Filippini, Massimo ; Masiero, Giuliano

In: Economic Modelling, 2015, vol. 51, p. 289-298

Population aging is challenging governments to find new solutions to finance the increasing demand for nursing home care and slow down the increase in expenditures. In this light, many European countries are currently considering reforms to increase efficiency in the provision of nursing home services. One popular restructuring policy is the transformation of public organizations into private...
