Financial and Political Factors Motivating the Privatisation of Municipal Water Services

Abstract: Financial and political factors are widely considered to be an explanatory factor of the privatisation of public services. However, the empirical evidence in this respect is not convincing. This paper considers elements of long-term financial condition and ideological and political strength, together with other socio-economic factors and the effects of the current global financial crisis, to address the financial stress–privatisation relationship, with respect to urban water services, observed during the period 2002–2012 in Spanish municipalities. A discrete time survival model is applied, and the results obtained show that certain elements of financial condition, together with political and ideological factors, are decisive influences in decisions to privatise urban water services. We also highlight the major impact of the Great Recession and its effect on the financial stress–privatisation relationship.

Do local authorities use NPM delivery forms to overcome problems of fiscal stress

Abstract: Finding solutions to the unfavourable economic and financial situation that the local authorities are currently facing is of crucial importance. One such solution is to adopt mechanisms for restructuring local public services, through new management approaches to reduce costs and thereby reduce fiscal stress. The aim of this article is to determine the probability of a city council changing the way it manages services, selecting from different options, in response to situations of fiscal stress. To address this issue, we studied a sample of 1572 Spanish municipalities for the period 2002–2009, using a random-effects panel multinomial logit model. The results obtained show that outsourcing and inter-municipal cooperation are the management formulas that councils are most likely to choose in response to a financial crisis, especially the ones arising from insufficient transfers, negative cash flow, debt or budget deficit.

Modeling Fiscal Stress and Contracting Out in Local Government: The Influence of Time, Financial Condition, and the Great Recession

Abstract: Various studies have analyzed the relationship between fiscal stress and contracting out, but have failed to achieve conclusive results. In this article, we take a broad view of fiscal stress, addressed in terms of financial condition and studied over a lengthy period (2000-2010). The relationship between fiscal stress and contracting out is studied using a dynamic model, based on survival analysis, a methodology that enables us to take into account the effect of time on this relationship. As this study period includes the years of the Great Recession (2008-2010), we also highlight the impact of this event on the fiscal stress–contracting out relation. The results obtained suggest that taking into account the passage of time and conducting a long-term assessment of financial condition enable a more precise understanding of this relation. We also find that the Great Recession reduced the probability of local governments’ contracting out public services.

Estimation and Inference in Nonparametric Frontier Models: Recent Developments and Perspectives

Abstract: Nonparametric estimators are widely used to estimate the productive efficiency of firms and other organizations, but often without any attempt to make statistical inference. Recent work has provided statistical properties of these estimators as well as methods for making statistical inference, and a link between frontier estimation and extreme value theory has been established. New estimators that avoid many of the problems inherent with traditional efficiency estimators have also been developed; these new estimators are robust with respect to outliers and avoid the well-known curse of dimensionality. Statistical properties, including asymptotic distributions, of the new estimators have been uncovered. Finally, several approaches exist for introducing environmental variables into production models; both two-stage approaches, in which estimated efficiencies are regressed on environmental variables, and conditional efficiency measures, as well as the underlying assumptions required for either approach, are examined.

Inter-municipal cooperation and costs: expectations and evidence

Abstract: Austerity and fiscal crisis make the search for cost-saving reforms in local government more critical While cost savings from privatization have frequently proven ephemeral, inter-municipal cooperation has been a relatively understudied reform We analyse the literature on cost savings under cooperation and find that savings are dependent on (1) the cost structure of public services, particularly those related to scale and density economies and externalities, (2) the structure of local government (size, metropolitan location, powers granted by the nation or regional state), and (3) the governance framework at the local/regional level where cooperation varies from informal to formal European studies give more emphasis to cost savings, while US studies focus on coordination concerns arising from the higher degree of devolution in the US local government system
