Purpose – This paper seeks to extend the analysis of performance management regimes by Bouckaert and Halligan to other countries in order to contribute to the developing theory of forms and challenges in public sector performance management.Design/methodology/approach – The state of performance management and the context in which it has evolved is assessed in seven different countries using dimensions drawn from Bouckaert and Halligans work along with elements from earlier work by Pollitt and Bouckaert. These are summarized in a table and comparisons made to generate additional insights into the factors that influence the shape and speed of public management evolution.Findings – The paper finds that the Bouckaert and Halligan framework for analyzing public sector performance management is useful, albeit with some modifications. Specifically, it finds that administrative culture is a key factor influencing the speed of reform and that the attitude of elites (politicians and civil servants, in most cases) ...

Alternative management structures for municipal waste collection services: The influence of economic and political factors

Ana María Plata-Díaz; José Luis Zafra-Gómez; Gemma Pérez-López; Antonio Manuel López-Hernández

Identifying and characterising the factors that determine why a local authority opts for a particular way of managing its waste collection service is an important issue, warranting research interest in the field of municipal solid waste (MSW) management. This paper presents empirical evidence spanning a broad time horizon (2002–2010) showing that economic and political factors impact in different ways on the provision of waste management services. We examine five alternatives in this area, including public and private service delivery formulas and, within each field, individual and joint options. Our findings highlight the importance of the service cost and that of the various indicators of fiscal stress as determinant factors of management decisions regarding the provision of MSW management services. 2014 Elsevier Ltd.

Cost efficiency in municipal solid waste service delivery. Alternative management forms in relation to local population size

Gemma Pérez-López; Diego Prior; José Luis Zafra-Gómez; Ana María Plata-Díaz

Considerable research has been devoted to the analysis of efficiency and of management forms for municipal waste collection, but widely varying results have been reported. In this paper, the metafrontier approach, by means of order-m frontiers, is used to analyse the efficiency of different ways of managing waste collection services, in order to determine which form is more appropriate. We compare the results obtained with this approach against those of previous theories. The advantage of applying this methodology is that unlike traditional nonparametric frontier analysis, we can compare the efficiency of different groups of municipalities according to their population size and to the management form adopted to supply the service. The results obtained suggest that, in general, cooperation formulas are the most suitable for the waste collection service. Thus, intermunicipal cooperation performs best in smaller municipalities (up to 20,000 inhabitants). However, we find that contracting out the service is associated with higher levels of efficiency in municipalities with more than 20,000 inhabitants.

Privatisation of waste collection services in response to fiscal stress in times of crisis

According to the conventional theoretical framework, fiscal stress is an explanatory factor of privatisation, since the latter can provide economies of scale and cost savings, as indicated by the theory of public choice. However, urban planning theories suggest that public choice does not take into account the collective needs of those receiving public services. The present study aims to clarify two major issues. Firstly, in the presence of fiscal stress, do public managers really privatise? And secondly, does privatisation harm the public interest? To investigate these questions, we constructed and analysed a discrete-time survival model, which was applied to the period 2000–2010, to reflect the effects of the current global financial crisis on the fiscal stress–privatisation relationship with respect to urban waste collection services. The results obtained indicate that when certain aspects of financial condition worsen, the likelihood of public services being privatised increases. This was the case during the Great Recession of 2008–2010, especially when a neighbouring municipality had previously privatised its services. After privatisation, service quality did not vary significantly, and so we conclude that public choice does not prejudice the public interest.

Understanding the Dynamic Effect of Contracting Out on the Delivery of Local Public Services

Juan A. Mañez; Gemma Pérez-López; Diego Prior; José Luis Zafra-Gómez

Máñez J., Pérez-López G., Prior D. and Zafra-Gómez J. L. Understanding the dynamic effect of contracting out on the delivery of local public services, Regional Studies. Contracting out is a mechanism through which the delivery of public services can be made more efficient. However, the process has yielded conflicting results. This paper presents a dynamic, mixed approach, incorporating an intertemporal frontier and a matching technique, to measure the short- and long-term effects of the implementation of contracting out on the efficiency of local public service delivery. The study demonstrates the existence of temporary inefficiency arising from the change in service management when contracting out takes place, followed by an increase in efficiency among municipalities that contract out, with respect to comparable municipalities that do not do so.

Explanatory factors in the renewal of contracts for the privatisation of public services

Cristina M Campos-Alba; Emilio José de la Higuera-Molina; Gemma Pérez-López; José Luis Zafra-Gómez

After analysing the explanatory factors underlying the renewal of privatisation contracts, this paper examines the likelihood of local authorities renewing their contracts with private entities for the provision of public services, by studying a sample of 623 Spanish municipalities for the period 2002–2013, using a logit model. The type of service, the duration of the contract and certain political and economic factors were all found to influence the renewal or otherwise of this type of contract. Moreover, this effect differed between initial privatisation and subsequent contract renewal.
