GOVERNMENT CONSUMPTION AND THE COMPOSITION OF PRIVATE EXPENDITURE: A CONDITIONAL ERROR CORRECTION MODEL

In this paper we provide empirical evidence of the relationship between government purchases and private expenditure by adopting a microeconomic approach. Using UK quarterly data, a long‐run demand system conditioned to the public sector is obtained by specifying a vector error correction model in which government consumption is assumed as an exogenous I(1) forcing variable. Our findings reject the hypothesis of separability of individual preferences between public and private expenditures, with simultaneous crowding‐out/in effects. Moreover, crowding‐out effects of government consumption on private spending are found to be larger for those goods and services that produce similar utility.     

COMPARING PPP WITH TRADITIONAL PROCUREMENT: THE CASE OF SCHOOLS PROCUREMENT IN IRELAND

Advocates of public‐private partnerships (PPPs) argue that they can deliver public infrastructure more efficiently than traditional procurement through timelier completion and superior value for money. Despite these claims comparative analysis of the performance of both procurement methods has received scant attention in the PPP literature to date. This paper addresses this issue by providing an in‐depth, case‐based comparison of PPP versus traditional procurement in the schools sector in Ireland. Through detailed semi‐structured interviews with key stakeholders and an examination of the available documentation, we assess whether the key objectives of using PPP have been achieved. Overall, we find no evidence that PPP leads to faster delivery of infrastructure when the overall procurement process from contract notice to delivery is accounted for. In addition, we find only limited evidence to suggest that PPP results in better value for money.     

THE USE OF PPP ARRANGEMENTS IN STREET LIGHTING: A WIN‐WIN OPTION?

Street lighting is a classic example of a public good, and governments are extensively involved in its provision. Adequate lighting facilitates both car traffic and personal safety while improving an urban area's character. However, many systems are mismanaged and obsolete, incurring high energy costs and emissions with relatively low lighting quality. Public authorities facing budget constraints often find retrofitting old street‐lighting systems challenging. They have two options: either direct in‐house, public‐authority renovation or contracting with a private company through a public–private partnership (PPP). Although private‐sector‐participation approaches vary, most public authorities can now enter into a street‐light modernization PPP agreement. That can be a win‐win option for both the public and private sectors. The upfront investment is small and operational expenses outweigh capital expenses, generating lower payback periods and energy‐cost reduction with light‐emitting diode (LED) technology. Little public expenditure is necessary when private partners are compensated via shared energy savings. We analyze the Detroit street‐light PPP – the United States’ first – and find that PPPs are practical for retrofitting US street lights and in other countries where they are antiquated.     

Public investment in developing countries: A blessing or a curse?

This paper analyzes the relationship between public and private investment in developing countries. We set up a simple theoretical model where two countervailing forces coexist. On the one hand, public investment raises the marginal productivity of private capital and leads to potential crowding-in of private investment. On the other hand, weak institutions and restricted access to financing could diminish the positive effects of public investment projects and crowd-out private investment. The empirical results - which exploit both the time series and cross sectional variation in the data using a panel of 116 developing countries with annual observations between 1980 and 2006 - suggest that on average the crowing-out effect dominates. Moreover, we find that this crowing-out effect is dampened (or even reversed) in countries with better institutions - where the marginal productivity of public investment is conceivably higher - and that are more open to international trade and financial flows, such that financing constraints are less binding.     

WHAT DO CITIZENS THINK ABOUT PUBLIC ENTERPRISES? SUBJECTIVE SURVEY DATA ON THE LEGITIMACY OF THE ECONOMIC ACTIVITIES OF THE GERMAN PUBLIC SECTOR

We analyse the legitimacy of public enterprises that perform economic activities by focusing on the citizens’ subjective preferences, i.e. determining their political legitimacy. Using data from a representative survey conducted among 318 citizens of the German state of Rhineland‐Palatine, we explore determinants for the support of either privatisation efforts or the instrumental thesis, a widespread principle in German‐speaking countries, which considers public enterprises solely as instruments to fulfil economic policy objectives. Our results indicate that the respondents’ perception of the efficiency of public enterprises as well as their personal economic situation are important factors for the support of privatisation. The influential factors for the use of public enterprises as policy instruments are political ideology, the perception of a higher security of supplying goods and services as well as opinions regarding corporate social responsibility. The subjective preferences of a (democratic) country's citizens are thus an important reason why the public sector should or should not play an active part in providing goods and services. This can play an important role when decision makers from the public sector are keen to take into account the citizens’ approval or disapproval of privatisation measures.     

EVALUATING THE COSTS,QUALITY, AND VALUE FOR MONEY OF INFRASTRUCTURE PUBLIC‐PRIVATE PARTNERSHIPS: A SYSTEMATIC LITERATURE REVIEW

Public?private partnerships (PPPs) are often promoted as a means to lower the costs and increase the quality and value for money (VfM) of public construction and infrastructure projects. While the increasing capital stock of PPPs warrants evaluation of their performance there has until now been limited systematic assessment of PPP versus conventional public procurement. This article contributes to the literature by presenting the findings of a systematic review of empirical peer‐reviewed studies comparing the costs, quality, and/or VfM of infrastructure PPP projects with conventional public procurement. The international literature suggests that PPPs are on average more costly and provide approximately similar VfM as conventional procurement. The number of empirical evaluations is limited, however, and evidence on the quality of infrastructure facilities is particularly scarce. While infrastructure PPPs continue to proliferate, systematic assessment of their performance is warranted to assist policy‐makers in choosing the procurement method that offers best value for taxpayers, users and society.     

PORTFOLIO ALLOCATION IN THE FACE OF A MEANS‐TESTED PUBLIC PENSION

We investigate whether households adjust their asset portfolios just prior to retirement in ways that are consistent with maximizing eligibility for a means‐tested public pension. We utilize detailed micro data for a nationally‐representative sample of Australian households to estimate a system of asset equations which are constrained to add up to net worth. Our results provide little evidence that healthy households or couples are responding to the incentives embedded in the means tests determining pension eligibility by reallocating assets. While there are some differences in asset portfolios associated with having an income near the income threshold, being of pensionable age, and being in poor health, these differences are often only marginally significant and are not clearly consistent with the incentives inherent in the Australian age pension eligibility rules. Any behavioral response to the incentives inherent in the age‐pension means test appears to be predominately concentrated among single pensioners who are in poor health.     

A UNIFIED ANALYSIS OF TRADE GAINS IN THE PRESENCE OF PUBLIC GOODS*

It has long been known that free trade is potentially (after lumpsum compensatory transfers) beneficial for each trading country if the autarkic and post‐compensation free‐trade equilibria are perfectly competitive, with market distortions limited to non‐negative taxes on imports and exports. However these conditions are merely sufficient. It can now be shown that, under alternative sufficient conditions, free trade is potentially beneficial to each trading country even in the context of public goods.     

Pension reforms and saving gains in the United Kingdom

The empirical validity of the effect of pension reforms on domestic savings in the UK has been investigated using an Auto‐regressive Distributed Lag (ARDL) model capable of testing for the existence of a long‐run relationship regardless of whether the underlying time series are individually I(1) or I(0). The total savings response to change in pension savings is positive and significant, but an increase in occupational pension saving appears offset by a decrease in other forms of saving. This paper concludes that there is no firm evidence that aggregate savings increase considerably because of privately funded pension schemes.     

CLASSIFICATION PROBLEMS AND THE DIVIDING LINE BETWEEN GOVERNMENT AND THE MARKET: AN EXAMINATION OF NHS FOUNDATION TRUST CLASSIFICATION IN THE UK

ABSTRACT: In this paper we argue that national accounting categories provide an inadequate basis for evaluating differences between public and private sector services. This is because accounting categories rely on economic concepts such as market price but do not take account of substantive public policy goals such as universality. The argument has important consequences for the structures and systems of delivery especially where nonprofit providers and social enterprise models are substituted for public bodies formerly integrated into the government's delivery system. Using an example taken from the UK's National Health Service, we show that the mechanisms for ensuring universality through redistribution are not sufficiently taken into account for classification purposes.     

MEASURING POVERTY USING BOTH INCOME AND WEALTH: A CROSS‐COUNTRY COMPARISON BETWEEN THE U.S. AND SPAIN

We study the correspondence between a household's income and its vulnerability to income shocks in two developed countries: the U.S. and Spain. Vulnerability is measured by the availability of wealth to smooth consumption in a multidimensional approach to poverty, which allows us to identify three groups of households: the twice‐poor group, which includes income‐poor households who lack an adequate stock of wealth; the group of protected‐poor households, which are all those income‐poor families with a buffer stock of wealth they can rely on; and the vulnerable‐non‐poor group, including households above the income‐poverty line that do not hold any stock of wealth. Interestingly, the risk of belonging to these groups changes over the life‐cycle in both countries while the size of the groups differs significantly between Spain and the U.S., although this result is quite sensitive to whether the housing wealth component is included in the wealth measure or not.     

ON THE ROBUSTNESS OF PRIVATE LEADERSHIP IN MIXED DUOPOLY

We investigate a mixed duopoly where a state‐owned public enterprise competes against a profit‐maximising private enterprise. We analyse whether private leadership or public leadership is robust in the observable delay game. We find that private leadership is always risk dominant. We also investigate how ownership structure in a public firm affects the equilibrium distribution of roles. We find that the roles are as follows: (1) Cournot, when the degree of privatisation is low, (2) private leadership, when it is middle, (3) both private leadership and public leadership, when it is high. The result implies that private leadership is again more robust.     

POLITICAL INEQUALITY,CENTRALIZED SANCTIONING INSTITUTIONS,AND THE MAINTENANCE OF PUBLIC GOODS

Centralized sanctioning institutions cultivate cooperation by eradicating the gains from free‐riding. Studies show that electing a community member to operate a centralized sanctioning institution further increases support for the public good. These studies have overlooked an all‐too‐common attribute of non‐laboratory elections: political inequality. In this paper, we replicate those studies and, then, introduce novel experimental treatments that examine how political inequality influences the cooperation‐enhancing effect of a democratic election to centralized sanctioning institutions. In our novel treatment conditions, participants receive either a random allotment of votes that they can use to elect a centralized sanctioning authority or an allocation of votes proportional to their earnings in a previously‐executed public goods game. We find that political inequalities created via the random allocation of votes do not hinder cooperation, whereas political inequalities created via past game play undermine elected authorities and diminish contributions to the public good from individuals advantaged by political inequality.     

THE BLACK SOCIAL ECONOMY: PERSEVERANCE OF BANKER LADIES IN THE SLUMS

In a neoliberal world where commercial financial services are controlled by elites, poor Black women in the slums are usually excluded from financial programs – even microfinance ones. In my empirical study of 491 people in Jamaica, Guyana and Haiti, I argue that the participation in informal banking systems by the poor, not only provides coping tools for livelihood survival, but banker ladies insert a program of social connectedness and political action when they organize these local resources. Banker ladies have a clear social justice agenda: to validate the business activities of marginalized people. Informal banks are a counter project to neoliberalism because it is focused on the collective, where poor Afro‐Caribbean women are creating alternative financial programs that are squarely part of the social economy.     

SHOULD A MANDATORY SUBORDINATED DEBT POLICY BE INTRODUCED IN THE UNITED KINGDOM? EVIDENCE FROM THE ISSUANCE ACTIVITY OF BANKS AND BUILDING SOCIETIES

Current research is beginning to question the role and effectiveness of traditional rules‐based bank regulatory oversight in favor of incentive‐compatible regulatory design and market discipline and, in particular, mandatory subordinated debt market discipline. However, research on the suitability of a mandatory subordinated debt policy (MSNDP) has focused primarily on the United States. The primary aims of this article, therefore, are to examine the market for subordinated debt (SND) issued by UK credit institutions and to assess the suitability of introducing an MSNDP into UK banking regulation. A further contribution of this article is that it explores SND issuance and its characteristics at a bank level and, uniquely, considers them in relation to regulatory, structural, and economic events that either are specific to the UK or otherwise affect international banks. The article compares the UK findings with research on SND markets in the United States and Europe and, in so doing, raises concerns over whether an MSNDP for the largest global credit institutions would be feasible. Although the focus of this study is the UK banking industry, the country‐focused bank‐level approach provides conclusions that might be relevant to other countries considering the implementation of an MSNDP.(JEL G18, G28)     

An analysis of public adaptation to climate change using agricultural water schemes in South America

This paper provides an analysis of public adaptation to climate change using agricultural water schemes in South American farms. Unlike other studies of adaptation, this paper examines the differences between private irrigation and public irrigation schemes based on around 1400 farm surveys collected across seven countries in South America which recorded detailed water schemes. We analyze the choice of water schemes in the first stage and the land values for each scheme in the second stage. We find that public irrigations do not increase in response to a warmer climate, but private irrigations do. On the other hand, we find that public irrigation schemes are provided primarily as a response to water scarcity. Moreover, we find that private irrigations are taken gradually while public irrigations are provided as a lump sum, resulting in either too much or too little provision. Therefore, public adaptations to climate change will likely involve two inefficiencies. No provision of irrigation in a hotter climate may result from a lack of knowledge. Overprovision of irrigation in dry zones may result from a lump-sum provision of a public good.     

Testing separability of public consumption in household decisions

In this paper we propose a sequential strategy, based on the microeconomic approach of the demand theory, in order to test for separability between private and public consumption. The aim of the present work is to verify, using a conditional almost ideal demand system, whether the different components of public consumption exert conditioning effects on the allocative structure of private spending. The empirical estimation of the model and the separability tests are developed for both a demand system in five functional categories of private spending, and for a demand system in six categories, where the private expenditures on those goods and services which can also be offered by the public sector are enclosed in a single functional category. The results of the separability tests, obtained using UK data for the 1974–2000 period, show that public individual consumption plays an important role in modifying consumer choices, while public collective consumption does not affect private consumption behaviours. The relationships between the different components of private spending and public individual consumption are both of substitutability and complementarity; in particular, we find that public individual consumption and the corresponding private expenditures on ‘Health, education, recreation and social protection’ are complements.     

Optimal Redistribution with Productive Social Services

Publicly‐provided private goods are conventionally considered consumer goods. Departing from this perspective, we analyze the public provision of inputs that improve household productivity (e.g., education and childcare). In a two‐class economy with distorting taxation, public provision is always welfare improving with respect to pure taxation, given that the public input directly affects household productivity. Moreover, the case for public provision strengthens as households' heterogeneity in input demand fades out, contrary to consolidated results in the literature. The features of optimal provision schemes depend on the nature of publicly provided input, namely, if it substitutes household productive capacity or just helps households to exploit it.     

The dual nature of public goods and congestion: the role of fiscal policy revisited

Abstract The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption‐based instruments in conjunction with the income tax. An income tax‐financed increase in government spending dominates both lump‐sum and consumption tax‐financing. Replacing the lump‐sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax. These results contrast sharply with the literature, where the consumption tax is generally viewed as the least distortionary source of public finance.
