This book offers an innovative, interdisciplinary approach to thinking about inequality, and to understanding how inequality is produced and reproduced in the global South. Without the safety net of the various Northern welfare states, inequality in the global South is not merely a socio-economic problem, but an existential threat to the social contract that underpins the democratic state and society itself. Only a response that is firmly grounded in the context of the global South can hope to address this problem. This collection brings together scholars from across the globe, with a particular focus on the global South, to address broad thematic areas such as the conceptual and methodological challenges of measuring inequality; the political economy of inequality in the global South; inequality in work, households and the labour market; and inequalities in land, spaces and cities. The book concludes by suggesting alternatives for addressing inequality in the global South and around the world. The pioneering ideas and theories put forward by this volume make it essential reading for students and researchers of global inequality across the fields of sociology, economics, law, politics, global studies and development studies.

We introduce a novel diagnostic tool to improve the performance of public services. We propose a method to compute performance/productivity ratios, which can be applied as soon as data on production units' outcomes and resources are available. Assuming outcome improvement as the main objective in a public services context, these ratios have an intuitive interpretation: values below unity indicate that better outcomes can be attained through weaker resource constraints (pointing at scarcity of resources) and, conversely, values above unity indicate that better outcomes can be achieved with the given resources (pointing at unexploited production capacity). We demonstrate the practical usefulness of our methodology through an application to secondary schools, where we account for outlier behaviour and environmental effects by using a robust nonparametric estimation method. Our results indicate that in most cases schools' performance improvement is a matter of unexploited production capacity, while scarcity of resources is a lesser issue.

We experimentally study how receiving information about tax compliance of others affects individuals’ occupational choices and subsequent evading decisions. In one treatment individuals receive information about the highest tax evasion rates of others in past experimental sessions with no such social information; in another treatment they receive information about the lowest tax evasion rates observed in the past sessions with no such social information. We observe an asymmetric effect of social information on tax compliance. Whereas examples of high compliance do not have any disciplining effect, we find evidence that examples of low compliance significantly increase tax evasion for certain audit probabilities. No major differences are found across countries.

How does the mother’s labour supply affect the household’s demand for childcare? And thus are formal and informal childcare substitutable? In this paper, we address these two questions using micro-data for 14 European countries observed over the period between 2010 and 2017. Relying on a Control Function Approach to account for the endogeneity between childcare and the mothers’ labour supply, we identify different factors affecting the demand for formal and informal childcare. The results show that the mother’s labour supply is a key element in understanding the demand for childcare and suggest that the more the mother participates in the labour market, the higher the household’s demand for childcare services. Moreover, our results support the substitutability hypothesis between formal and informal childcare. Policymakers aiming to promote mothers’ employment should increase the availability of formal childcare services, as this will increase labour supply by mothers and reduce the use of informal care arrangements.

The purpose of this paper is to test alternative models of long-term caring motives. We consider three main motives: pure altruism, exchange and family norm. Our database is the second wave of the Survey of Health, Ageing and Retirement in Europe (SHARE) which allows linking almost perfectly and with complete information children and their parents’ characteristics. Comparing the empirical results to the theoretical models developed, it appears that, depending on the regions analyzed, long-term caring is driven by moderate altruism or by family norm, while Alessie et al. (De Economist 162(2):193–213, 2014), also using SHARE data, stress the importance of exchange motive in intergenerational transfers.

This paper examines the robustness of the optimal lockdown strategy to the postulated social welfare criterion.We show that utilitarianism can, under some conditions, imply a COVID-19 variant of Parfit’s (1984) Repugnant Conclusion: for any (interior) lockdown with life periods of low quality, there must be a stricter lockdown that is regarded as better, even though this reduces the quality of life periods even more. On the contrary, the ex post egalitarian criterion (giving priority to the worst-off ex post) implies zero lockdown. Varying between its minimal and its maximal levels, the optimal lockdown is not robust to the postulated ethical criterion. We also identify a general ethical dilemma between the goal of saving lives (modeled by the Survivors Number Count axiom) and the goal of giving priority to the worst-off (Hammond Equity).

In recent years, England and Wales have suffered droughts. This unusual situation defies the common belief that the British climate provides abundant water resources and has prompted the regulatory authorities to impose bans on superfluous uses of water. Furthermore, a large percentage of households in England consume unmetered water which is detrimental to water saving efforts. Given this context, we estimate the shadow price of water using a panel data from reports published by the Office of Water Services (Ofwat) for the period 1996 to 2010 (three regulatory periods). These shadow prices are derived from a parametric multi-output, multi-input, input distance function characterized by a translog technology. Following O'Donnell and Coelli (2005), we use a Bayesian econometric framework in order to impose regularity—monotonicity and curvature—conditions on a high-flexible technology. Consequently, our results can be interpreted at the firm level without requiring the need to base analysis on the averages. Our estimations offer guidance for regulation purposes and provide an assessment of how the water supply companies deal with water losses under each regulatory period. The relevance of the study is quite general as water scarcity is a problem that will become more important with population growth and the impact of climate change.

We experimentally investigate the impact of information disclosure on managing common harms that are caused jointly by a group of liable agents. Subjects interact in a public bad setting and must choose ex ante how much to contribute in order to reduce the probability of causing a common damage. If a damage occurs, subjects bear a part of the loss according to the liability-sharing rule in force. We consider two existing rules: a per capita rule and a proportional rule. Our aim is to analyze the relative impact of information disclosure under each rule. We show that information disclosure increases contributions only under a per capita rule. This result challenges the classical results regarding the positive effects of information disclosure, since we show that this impact may depend upon the legal context. We also show that while a proportional rule leads to higher contributions than a per capita one, the positive effect of disclosure on a per capita rule makes it as efficient as a proportional rule without information disclosure.

Declining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related questions. The project employs a harmonized approach to conduct within-country analyses that are combined for meaningful cross-country comparisons. The key lesson is that the choices of policy makers affect the incentive to work at older ages and these incentives have important effects on retirement behavior.

We investigate whether and how an individual giving decision is affected in risky environments in which the recipient’s wealth is random. We demonstrate that, under risk neutrality, the donation of dictators with a purely ex post view of fairness should, in general, be affected by the riskiness of the recipient’s payoff, while dictators with a purely ex ante view should not be. Furthermore, we observe that some influential inequality aversion preferences functions yield opposite predictions when we consider ex post view of fairness. Hence, we report on dictator games laboratory experiments in which the recipient’s wealth is exposed to an actuarially neutral and additive background risk. Our experimental data show no statistically significant impact of the recipient’s risk exposure on dictators’ giving decisions. This result appears robust to both the experimental design (within subjects or between subjects) and the origin of the recipient’s risk exposure (chosen by the recipient or imposed on the recipient). Although we cannot sharply validate or invalidate alternative fairness theories, the whole pattern of our experimental data can be simply explained by assuming ex ante view of fairness and risk neutrality.
