Social Indicators Research - Following the outbreak of COVID-19 and its heavy toll on the global community and humanity, a fierce debate on the pandemic and Sustainable Development Goals (SDGs)...     

Whom should we believe? Aggregation of heterogeneous beliefs

We examine the collective risk attitude of a group with heterogeneous beliefs. We prove that the wealth-dependent probability distribution used by the representative agent is biased in favor of the beliefs of the more risk tolerant consumers. Moreover, increasing disagreement on the state probability raises the state probability of the representative agent. It implies that when most disagreements are concentrated in the tails of the distribution, the perceived collective risk is magnified. This can help to solve the equity premium puzzle. We show that the trade volume and the equity premium are positively correlated.

The economics of adding and subdividing independent risks: Some comparative statics results

In this paper we address the problem of determining whether adding independent risks or subdividing them is a good substitute for insurance. Despite the fact that accepting more i.i.d. risks increases total risk, it is shown that some risk-averse decision makers can rationally reduce their demand for insurance by doing so. Similarly, a better diversified portfolio of i.i.d. risky assets can rationally be more insured, even if diversification is a risk-reduction scheme. We derive conditions sufficient to obtain unambiguous comparative statics results. Assuming that absolute risk aversion is decreasing and that the fourth derivative of the utility function is positive, we show that diversification is an exceptionally good substitute for insurance. Under the same conditions, adding independent risks to wealth reduces the demand for insurance on each unit.     

The East Asian welfare model

This article aims to outline main features of the East Asian welfare model, to understand its past development and assess lessons that can be learned for other developing and developed countries. It describes the particular path of welfare state development in Japan, South Korea, Taiwan, Hong Kong and Singapore, by focusing particularly on developmental and political aspects of welfare state development. In the final part of the study, particular features of the East Asian welfare model are outlined, and thus the existence of a distinct, ideal-typical welfare regime in East Asia substantiated.     

Differences in the Seriousness of Problems and Deservingness of Help: Swedish Social Workers' Assessments of Single Mothers and Fathers

In this vignette study, three hypotheses concerning differencesin social workers’ assessment off single fathers and mothersare tested: first, that single fathers with custody of theirchildren, who have problems similar to those often faced bysingle mothers, are assessed as having more serious problemsthan the mothers; secondly, that single fathers in such a situationtend to be assessed as being less deserving of support thansingle mothers in the same situation; thirdly, that the helpoffered to both sexes follows gender-traditional patterns. Theresults support the hypotheses. The overall problems and mentalhealth tended to be assessed as more serious in the case ofthe father than in the case of the mother. The single fatherwas assessed as being more responsible for his situation. Thesingle mother was assessed as being in need of assistance inmore areas and more varied social welfare measures were recommendedfor her than for the father. Finally, the results also showthat only support which could enable the client to obtain paidwork and be able to pay off the debts on his car was given higherpriority in the case of the father.     

Cross-country determinants of life satisfaction: exploring different determinants across groups in society

This paper explores a wide range of cross-country determinants of life satisfaction exploiting a database of 90,000 observations in 70 countries. We distinguish four groups of aggregate variables as potential determinants of satisfaction: political, economic, institutional, and human development and culture. We use ordered probit to investigate the importance of these variables on individual life satisfaction and test the robustness of our results with Extreme Bounds Analysis. The results show that only a small number of factors, such as openness, business climate, postcommunism, the number of chambers in parliament, Christian majority, and infant mortality, robustly influence life satisfaction across countries while the importance of many variables suggested in the previous literature is not confirmed. This remains largely true when the analysis splits national populations according to gender, income, and political orientation also. We thank Stephen Lea, participants at the 30th IAREP conference in Prague and the referees of this journal for comments on earlier versions. Gilles Winkler provided excellent research assistance.     

The Role and Function of the Faculty Field Liaison

This article examines the purposes, defines the role, and analyzes the functions of a faculty field liaison. It reflects the experience of faculty members who have carried this assignment as a major responsibility. In recognition of the impact of this role on the educational process and the need for it to be clearly understood, the authors have attempted to distill its essence and to clarify the requirements for its effective practice.     

On moment indeterminacy of the Benini income distribution

The Benini distribution is a lognormal-like distribution generalizing the Pareto distribution. Like the Pareto and the lognormal distributions it was originally proposed for modeling economic size distributions, notably the size distribution of personal income. This paper explores a probabilistic property of the Benini distribution, showing that it is not determined by the sequence of its moments although all the moments are finite. It also provides explicit examples of distributions possessing the same set of moments. Related distributions are briefly explored.
