Cooperative provision of indivisible public goods

A community faces the obligation of providing an indivisible public good that each of its members is able to provide at a certain cost. The solution is to rely on the member who can provide the public good at the lowest cost, with a due compensation from the other members. This problem has been studied in a non-cooperative setting by Kleindorfer and Sertel (J Econ Theory 64:20–34, 1994). They propose an auction mechanism that results in an interval of possible individual contributions whose lower bound is the equal division. Here, instead we take a cooperative stand point by modelling this problem as a cost sharing game that turns out to be a ‘reverse’ airport game whose core is shown to have a regular structure. This enables an easy calculation of the nucleolus that happens to define the upper bound of the Kleindorfer–Sertel interval. The Shapley value instead is not an appropriate solution in this context because it may imply compensations to non-providers.

Estimating representations of time preferences and models of probabilistic intertemporal choice on experimental data

We here estimate a number of alternatives to discounted-utility theory, such as quasi-hyperbolic discounting, generalized hyperbolic discounting, and rank-dependent discounted utility with three different models of probabilistic choice. The data come from a controlled laboratory experiment designed to reveal individual time preferences in two rounds of 100 binary-choice problems. Rank-dependent discounted utility and its special case—the maximization of present discounted value—turn out to be the best-fitting theory (for about two-thirds of all subjects). For a great majority of subjects (72%), the representation of time preferences in Luce’s choice model provides the best fit.     

A note on Chichilnisky's social choice paradox

One of the main results in topological social choice states the non-existence of a continuous, anonymous, and unanimous aggregation rule on spheres. This note provides a proof based upon simple methods such as integration.     

Risk and choice: A research saga

The economic theory of decision making under risk has seen remarkable advances over the 50 years since Pratt’s (1964) characterization of risk aversion under expected utility. We review developments in three key areas to which Louis Eeckhoudt has made significant contributions: (1) increases in risk and risk taking; (2) self-protection and risk aversion; and (3) higher (and lower) order derivatives of utility. For each, we identify seminal papers, puzzles, and recent developments. The saga of research on these topics reveals that important contributions were made long ago and yet significant gains in understanding continue to be made. Recent advances often have roots in early results and researchers can profit by examining the old as well as the new papers.     

A network ridesharing experiment with sequential choice of transportation mode

Within the last decade, there has been a dramatic bloom in ridesharing businesses along with the emergence of new enabling technologies. A central issue in ridesharing, which is also important in the general domain of cost-sharing in economics and computer science, is that the sharing of cost implies positive externalities and hence coordination problems for the network users. We investigate these problems experimentally in the present study. In particular, we focus on how sequential observability of transportation mode choices can be a powerful facilitator of coordination in ridesharing. Our study abstracts the essential issues of coordination in ridesharing into a directed network game with experimentally testable predictions. In line with the theoretical analysis, our experimental evidence shows that even a limited extent of sequential choice observability might lead to efficient coordination. However, convergence to efficiency is slower with more limited observability, resulting in a significant increase in travel cost.     

Free provision of services and cross-border labour recruitment

This article identifies how the use of the European Union (EU) mobility rules, as formulated by the EU's Posting Directive, has been linked to the temporary provision of services in practice. It demonstrates how this linkage, legitimised by European Court rulings, undermines the Directive's original intent to provide rights-based regulation of labour mobility in the Union. In the assessment of posting practices, striking findings of two studies co-conducted by the author in 2003 and 2010 are discussed. In the first section, the origins of the Directive are described, followed by sections that contextualise the posting rules in the framework of the fundamental economic freedoms of EU Treaties, and discuss the problems related to implementation and enforcement. Based on the Directive's definition of posting, three issues of governance and practice are raised: (a) regulation of the employment relationship, (b) application of labour conditions and (c) respect for collective agreements. A final section offers policy recommendations in order to deal with the ways in which posting governance and practices currently impede any vision of rights-based mobility in the EU. It is argued that current minimalist interpretation of the posting rules can neither guarantee equal treatment nor protect the rights of temporary migrant workers.     

A new framework for understanding subnational policy-making and local choice

This article presents a new and innovative framework to help analyse policy-making and depoliticisation within subnational governance arrangements. By focusing on the capacity (not the autonomy) of subnational governments to achieve their political objectives, and incorporating external actors along both the vertical and horizontal dimensions, it provides a dynamic tool to understand the extent to which municipal governments influence local policy-making processes. Furthermore, it stresses that greater ‘localism’ (or independence) between vertical tiers of government is likely to weaken subnational bodies and result in them becoming more interdependent with (or even dependent on) horizontal non-state actors within the locality. This would weaken their position in local governance arrangements and exacerbate the depoliticised nature of decision-making.     

The retrenchment of public pension provision in the liberal world of welfare during the age of austerity—and its unexpected reversal, 1980–2017

Pension system adaption during the “age of austerity” since 1980 is expected to vary between industrialized countries broadly in line with their membership of conservative, liberal, or social democratic worlds of welfare. Empirical testing on the liberal world focuses on the later period and differs in its conclusions. This paper is based on a systematic study of the scale, nature, and trajectory of change in six liberal pension systems between 1980 and 2017 using expenditure, economic, demographic, and social rights data. These data are analysed using a framework developed through critical engagement with Pierson's three welfare state change criteria and the welfare state “dependent variable problem.” The paper finds a significant retrenchment of public pension provision in most liberal welfare states after 1980 but largely during the first half of the period. This has been partly reversed in most countries since the mid‐1990s, though the scale of this reversal varies between countries. The recent rise of the state in liberal systems has been noted by some commentators, but to be properly understood, the paper argues, it must be considered in the context of the significant retrenchment, which preceded it. There is a scope especially for research on the broader social context of recent reforms, particularly how middle‐income groups were affected by retrenchment and how recent reforms have mitigated this.     

Determinants of welfare service provision after the Golden Age

Jensen C. Determinants of welfare service provision after the Golden Age Int J Soc Welfare 2011: 20: 125–134 © 2009 The Author, International Journal of Social Welfare © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. The welfare state literature exhibits a ‘transfer bias’ in the sense that very little research exists on welfare services or benefits in‐kind. This article presents one of the first systematic studies on the determinants of welfare service provision since the end of the Golden Age of welfare expansion. The article concludes that partisan factors do not drive change, although historically they may have been pivotal. Instead, new factors, including deindustrialisation, female labour force participation and rising public attention appear to be highly significant. It is argued that new studies need to take seriously both the individual characteristics of services as well as the changing social demands that the services are supposed to meet.     

A longitudinal study of depressiveness in children in public care

Rajhvajn Bulat L. A longitudinal study of depressiveness in children in public care Int J Soc Welfare 2010: 19: 412–423 © 2009 The Author, Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. The aim of this article is to analyse the challenges involved when making longitudinal observations of depressiveness in children raised in public care. The first measurement comprised 375 children from children's homes and foster families; however, most of the results are based on an analysis of the 139 children who participated in both parts of the research. We used the Child Depression Inventory and the anxiety/depression subscales of Youth Self Report and Child Behaviour Checklist as measures of depressiveness. The comparison of results from the first and second measurements showed that depressiveness in children in public care decreased over time. Children who grew up in children homes were, in the first measurement, more depressed than those living in foster families, but after five years that difference had disappeared. Furthermore, decrease in depressiveness is predominantly associated with less frequent delinquent, aggressive or hyperactive behaviour, less withdrawal and better control over uncomfortable emotions.     

On the consistency of choice

Consistency of choice is a fundamental and recurring theme in decision theory, social choice theory, behavioral economics, and psychological sciences. The purpose of this paper is to study the consistency of choice independent of the particular decision model at hand. Consistency is viewed as an inherently logical concept that is fundamentally void of connotation and is thus disentangled from traditional rationality or consistency conditions imposed on decision models. The proposed formalization of consistency takes two forms: internal consistency, which refers to the property that a choice model does not generate contradictory statements; and semantic consistency, which refers to the idea that a theory’s predictions are valid with respect to some observed data. In addressing semantic consistency, the relationship between theory and data is analyzed in terms of so-called duality mappings, which allow a passage between the two universes in a way that consistency is preserved. The formalization of consistency concepts relies on adapting the revealed preference theory to the context-dependent setting. The paper concludes by discussing the implications of the proposed framework and how it relates to classical revealed preference theory and other formalizations of the relationship between the theory and reality of choice.     

Ownership differences in the provision of outpatient substance abuse services

The authors examine the assumption of the 1980s that the provision and costs of substance abuse services, among others, could best be met by expanding programs in the private sector. The study presents a comparison of public and private substance abuse services, based on data drawn from a national sample of outpatient units, and develops a profile of treatment and financing within three auspice (ownership) categories--private nonprofit, private for-profit, and public. An input-throughput-output framework was used to assess the public-private differences within a wide range of organizational characteristics.     

Practitioners preferences of care coordination for older people: A discrete choice experiment

These findings demonstrate the importance of organisations providing care coordination for older people receiving long-term funding. Further research is required to investigate the influence of service setting on practitioner preferences.

This study explored practitioner preferences about the relative value of attributes of care coordination services for older people. A Discrete Choice Experiment (DCE) survey was used to identify the views of 120 practitioners from 17 services in England in 2015. The survey design was informed by an analysis of standards of care coordination, a postal survey and a consultation with carers of older people. Results of the DCE survey were supplemented by a content analysis of qualitative comments and fieldwork notes. Most respondents were over 30 years of age, female and almost half worked part-time. Continuity of care (care provided by the same care coordinator) and the ability to access the range of services outlined in the care plan were the most important service attributes. Service setting influenced practitioner preferences. Those in specialist services for people with dementia identified the length of time a service was provided as another important attribute. The DCE methodology has provided the opportunity to systematically canvas practitioner preferences.

Disparate goods and Rawls' difference principle: A social choice theoretic treatment

Rawls' Difference Principle asserts that a basic economic structure is just if it makes the worst off people as well off as is feasible. How well off someone is is to be measured by an index of primary social goods. It is this index that gives content to the principle, and Rawls gives no adequate directions for constructing it. In this essay a version of the difference principle is proposed that fits much of what Rawls says, but that makes use of no index. Instead of invoking an index of primary social goods, the principle formulated here invokes a partial ordering of prospects for opportunities.
