Estimating welfare changes from efficient pricing in public bus transit in India

Deb, Kaushik ; Filippini, Massimo

In: Transport policy, 2011, vol. 18, no. 1, p. 23-31

Three different and feasible pricing strategies for public bus transport in India are developed in a partial equilibrium framework with the objective of improving economic efficiency and ensuring revenue adequacy, namely average cost pricing, marginal cost pricing, and two-part tariffs. These are assessed not only in terms of gains in economic efficiency, but also in changes in travel demand...

Estimating dynamic consumption of antibiotics using panel data : the shadow effect of bacterial resistance

Filippini, Massimo ; Laura Guadalupe Gonzales Ortiz ; Masiero, Giuliano

To some extent, antibiotics are similar to addictive goods, since current consumption is reinforced by past use because of bacterial resistance, which represents a growing concern in many countries. The purpose of this paper is to explore how consumers adjust their current level of antibiotic consumption towards desired levels over time. We construct a balanced panel dataset (2000-2007) for 20...

Economies of vertical integration in the Swiss electricity sector

Fetz, Aurelio ; Filippini, Massimo

In: Energy economics, 2010, vol. 32, no. 6, p. 1325-1330

Over the last two decades, several European nations have introduced reforms to their electricity sector. Generally, these reforms require a legal and functional unbundling of vertically integrated companies. These unbundling processes may reduce the possibilities that exist to fruitfully exploit the advantages of vertical integration. The goal of this paper is to empirically analyze the...

Socioeconomic determinants of outpatient antibiotic use in Europe

Masiero, Giuliano ; Filippini, Massimo ; Ferech, Matus ; Goossens, Herman

In: International Journal of Public Health, 2010, vol. 55, no. 5, p. 469–478

Objectives: Outpatient antibiotic consumption widely varies across Europe. The investigation of the causes of such variation may help to identify interventions that would improve the efficient use of antibiotics. The aim of this study was to assess the impact of socioeconomic determinants and the role played by information about bacterial resistance. Methods: Comparable data on systemically...

Productivity growth and price regulation of Slovenian water distribution utilities = Rast produktivnosti i cjenovna regulacija vodoopskrbnih poduzeća u Sloveniji

Filippini, Massimo ; Hrovatin, Nevenka ; Zorić, Jelena: University of Ljubljana, Faculty of Economics, Ljubljana, Slovenia

In: Zbornik Radova Ekonomski Fakultet u Rijeka, 2010, vol. 28, no. 1, p. 89-112

This paper aims to analyse the price regulation method and performance of the water industry in Slovenia. A stochastic cost frontier model is employed to estimate and decompose the total factor productivity (TFP) growth of water distribution utilities in the 1997-2003 period. The main goal is to find out whether the lack of proper incentives to improve performance has resulted in the low TFP...

Do opening hours and unobserved heterogeneity affect economies of scale and scope in postal outlets?

Filippini, Massimo ; Koller, Martin ; Trinkner, Urs

The purpose of this study is to analyze the cost structure of Swiss Post’s postal outlets. In particular, the idea is to assess economies of scale and scope in post offices and franchised postal agencies. Information on their optimal size and production structure is of importance from the policy-makers’ point of view because this hypothetical situation may be a basis for calculation of...

Resource rent taxation and benchmarking : a new perspective for the Swiss hydropower sector

Banfi, Silvia ; Filippini, Massimo

In: Energy policy, 2010, vol. 38, no. 5, p. 2302-2308

The electricity generation in Switzerland is mainly based on hydropower (55% of total production). The exploitation of water in the hydropower sector can generate significant so-called resource rents. These are defined by the surplus return above the value of capital, labor, materials and energy used to exploit hydropower. In Switzerland, hydropower producers pay to the State a fixed fee per...

Public bus transport demand elasticities in India

Filippini, Massimo ; Deb, Kaushik

A number of static and dynamic specifications of a log linear demand function for public transport are estimated using aggregate panel data for 22 Indian states over the period 1990 to 2001. Demand has been defined as total passenger kilometers to capture actual market transactions, while the regressors include public transit fare, per capita income, service quality, and other demographic...

Physician dispensing and antibiotic prescriptions

Filippini, Massimo ; Masiero, Giuliano ; Moschetti, Karine

The regulation on prescribing and dispensing of antibiotics has a double purpose: to enhance access to antibiotic treatment and to reduce the inappropriate use of drugs. Nevertheless, incentives to dispensing physicians may lead to inefficiencies. We sketch a theoretical model of the market for antibiotic treatment and empirically investigate the impact of self-dispensing on the per capita...

Regional consumption of antibiotics : a demand system approach

Filippini, Massimo ; Masiero, Giuliano ; Moschetti, Karine

In: Economic Modelling, 2009, vol. 26, no. 6, p. 1389-1397

Through this paper, we have attempted to model the demand for different classes of antibiotics used for respiratory infections in outpatient care in Switzerland using a spatial version of the linear approximate Almost Ideal Demand System (AIDS) model. This model takes spatial dependency into account by means of spatial lags of antibiotic budget shares. We control for the health status of patients...
