The Effects of Local Government Consolidation on Turnout: Evidence from a Quasi‐Experiment in Switzerland

In the last decades, municipal mergers have been one major element of local government reforms in Switzerland and beyond. In this article, we describe and analyze the political effects of this development. We use a quasi‐experimental setting to test the impact of municipal mergers on electoral participation. We find that in merged municipalities, the decrease in turnout is significantly stronger than in non‐merged municipalities. Further, the effect is more pronounced in relatively small localities. There is a temporal dimension to this effect—that is, turnout drops mainly in the first election after the first merger, but not so much after the second or third merger. Hence, the study provides a skeptical yet differentiated perspective on the democratic consequences of municipal mergers and points to further research avenues to develop a more comprehensive understanding of local government consolidation.     

Municipal Mergers in New Zealand: An Empirical Analysis of the Proposed Amalgamation of Hawke’s Bay Councils

Local government policymakers across the developed world have frequently employed municipal amalgamation to improve the operation of local councils, and New Zealand is no exception. This paper empirically examines claims made in Potential Costs and Savings of Local Government Reform in Hawke’s Bay that the merger of the five local authorities in the Hawke’s Bay Region of New Zealand would generate significant cost-savings. We empirically test for the existence of scale economies in a single merged Hawke’s Bay council and find that no cost-savings can be expected. This removes a key argument for a forced Hawke’s Bay amalgamation.     

Did the Big Stick Work? An Empirical Assessment of Scale Economies and the Queensland Forced Amalgamation Program

In 2007, the Queensland Government imposed forced amalgamation with the number of local authorities falling from 157 to just 73 councils. Amalgamation was based inter alia on the assumption that increased economies of scale would generate savings. This paper empirically examines pre- and post-amalgamation (2006/07 and 2009/10) for scale economies. For the 2006/07 data, evidence of economies of scale was found for councils with populations up to 98,000, and thereafter diseconomies of scale. Eight percent of councils in 2006/07 (ten councils) – representing 64% of the state’s population – exhibited diseconomies of scale. For the 2009/10 data, the average cost curve remained almost stationary at 99,000 residents per council, but almost 25% of all councils (thirteen councils) were now found to exhibit diseconomies of scale. The compulsory merger program thus increased the proportion of Queensland residents in councils operating with diseconomies of scale to 84%.     

A Cautionary Tale: Council Amalgamation in Tasmania and the Deloitte Access Economics Report

Contemporary Australian public policy has come to rely increasingly on technical reports produced by commercial consultants in contrast to the traditional approach, which employed disinterested public servants to generate the specialist information required to inform decision makers. This approach is fraught with problems, not least the fact that ‘hired guns’ have strong incentives to create the ‘answers’ sought by their employers. By way of a ‘cautionary tale’, this paper examines the empirical evidence adduced in favour of radical amalgamation of Tasmanian local authorities in Local Government Structural Reform in Tasmania, produced by Deloitte Access Economics (DAE) (2011), and commissioned by the Property Council of Tasmania. In particular, the paper provides a critical analysis of the econometric modelling undertaken in the DAE (2011) Report. We find that if the DAE model is re‐estimated – employing alternative functional forms – then the empirical evidence in support of Tasmania council merges evaporates.     

Population size or population density? An empirical examination of scale economies in South Australian local government, 2015/16

ABSTRACT

Advocates of amalgamation typically claim that substantial scale economies flow from municipal mergers, which generate larger local government entities by population size. We examined whether economies of scale exist in council outlays by analysing the expenditure of 68 South Australian local government areas using data from the 2015/16 financial year. However, given the correlation between population size and population density it is important to determine whether the influence of population size on expenditure is due to variations in population density. We find that when local government areas are stratified into subgroups on the basis of population density, the evidence of economies of scale largely evaporates. From a policy perspective, this suggests that in place of municipal mergers, policymakers should instead explore avenues for shared service arrangements in those functions which exhibit scale economies.     

Notes on Contributors

This article draws from a major research project examining the impact of various forms of municipal consolidation in Australia and New Zealand. Its wide-ranging research involved studies of 15 cases of different forms of consolidation, including amalgamation, together with a series of interviews with senior practitioners from the local government sector. Data revealed little evidence of consistent economies of scale from consolidation, however both case studies and interviews indicated that consolidation generated economies of scope and what may be termed ‘strategic capacity’. While it was not possible to disaggregate the data for particular sizes of local authority, enhancement of strategic capacity was more obvious through processes of consolidation in larger ones and less so in smaller, more remote ones.     

论炎黄时代华夏族与东夷、苗蛮之融合

汉民族是中国的主体民族,在汉民族形成过程中,又以华夏为主体、揉合了其他民族的因素。炎黄时代,华夏、东夷、苗蛮三大集团以中原地区为核心,通过和平与非和平的方式,进行着密切的交流与融合。同时,各部落本身也在不断地发展变化,逐步分化出新的氏族和部落,华夏民族正是在这种膨胀与融合中逐步发展的。     

Why voluntary municipal merger projects fail: evidence from popular votes in Switzerland

ABSTRACT

What determines the failure of local government amalgamation referenda? Existing research suggests that functional pressures act as a push factor towards local territorial reform, whereas considerations of political self-determination exert a pull effect. However, we know little about the respective importance of these countervailing forces. In this paper, I analyze popular vote decisions on mergers of 541 municipalities involved in 166 different merger projects in three Swiss cantons since the new millennium. The results show that both functional pressures and concerns for self-determination are linked to popular vote outcomes: small municipalities are less likely to reject a merger. Concerns for self-determination matter, but only when the pressures of smallness are not overwhelming: a higher vote share of right-wing parties and a preponderance of other municipalities in the merger coalition increase the probability that voters reject a merger project. This has implications for policy-makers’ strategies when drafting and promoting voluntary local amalgamation reforms.
