An axiomatic analysis of the Nash equilibrium concept

The purpose of this paper is to analyze axiomatically the Nash equilibrium concept. The class of games under study is a (relatively large) subclass of n-person normal form games. Solutions are correspondences which associate to each game a non empty set of strategy vectors of this game. It is shown that if a solution satisfies the axioms Independence of irrelevant alternatives (IIA) and Individual rationality (IR), then all the strategy vectors in this solution are Nash equilibria. This result holds good also if IR is replaced by Strong individual monotonicity (SIM) or Weak principle of fair compromise (WPFC).     

Antisocial Propensity,Adolescent School Outcomes,and the Risk of Criminal Conviction

Data from the 1986 Northern Finland Birth Cohort Study (n = 4,645) were used to examine the influence of mid‐adolescent (age 15) school outcomes on late‐adolescent (ages 17–19) risk of criminal conviction. Consistent with social‐developmental theories of offending, we found that poor academic performance and reduced school attachment increase the risk of criminal conviction independently of pre‐existing differences in antisocial propensity and other confounding factors identified in prior research. Moreover, in support of an integrated model, our research suggests that academic performance and school attachment mediate the effects of childhood antisociality and learning difficulties on late‐adolescent risk of criminal conviction. The implications of findings for policy and future research are discussed.     

An exploration of third parties’ preference for compensation over punishment: six experimental demonstrations

Research suggests that to restore equity, third parties prefer compensation of a victim over the punishment of a perpetrator. It remains unclear, however, whether this preference for compensation is stable or specific to certain situations. In six experimental studies, we find that adjustments in the characteristics of the situation or in the available behavioral options hardly modify the preference of compensation over punishment. This preference for compensation was found even in cases where punishment might refrain a perpetrator from acting unfairly again in the future, and even when punishment has a greater impact in restoring equity than compensation does. Thus, the preference of compensation over punishment appears to be quite robust. Implications and ideas for future research are discussed.     

Association between gambling harms and game types: Finnish population study

Understanding of the harmfulness of game types is needed when planning harm minimization and prevention strategies. Adult data (N = 3555) from the Finnish Gambling 2015 survey was used to investigate the associations between different game types and gambling-related harms. A negative binomial regression model was used to analyse the effects of demographics, gambling involvement factors, and engaging in different game types on the number of gambling-related harms, which were evaluated by PGSI and SOGS. Age of 18–24, gambling several times a week, high relative expenditure, online gambling and engaging weekly either in scratch games, betting games or slot machine gambling were associated with a higher number of gambling harms. Chasing losses was the most typical harm among online poker players and fast-paced daily lottery game players, while poor self-control was the most typical harm with other game types, although some of the results were not statistically significant. Multiple factors were associated with gambling harms, including young age and gambling intensity. Games that provide a possibility for high-frequency gambling are more linked to harms. Recommendations should be implemented to incorporate effective harm-minimizing strategies in the regulation of specific game types both at the legislative level (provision and supply) and at the public health level.     

Immigrant-origin youth and the indecisiveness of choice for upper secondary education in Finland

The educational transitions of Finnish youth of immigrant background are challenging. They confront more difficulties in a twofold manner: they have more difficulties in transitioning to upper secondary education and they seem to drop out of education more often than their Finnish-origin counterparts. This study aimed to accomplish a view of the complex intertwinement of attitudes and experiences with upper secondary education choices, gender and origin. We compared immigrant- origin students (n?=?161) with Finnish-origin students (n?=?156) in a survey conducted during the final year of comprehensive school. Our objectives were to analyse the variation in attitudes, experiences and aspirations concerning post-comprehensive transition in gender and origin of the youth, and to analyse the factors behind the indecisiveness of the transitions. We concluded that youth with immigrant origin in general, and boys in particular, share a contradiction we termed the ‘paradox of immigrant schooling’, which refers to the combination of a positivity toward education and difficulties in learning and studying. We also found an immigrant-related contradiction between determinant and quite high occupational aspirations, and uncertainty of upper secondary choices. Our outcomes indicate that the immigrant-origin youth confront the upper-secondary choices in a much more complex and multidimensional situation than their Finnish-origin counterparts.     

Networking Enforced – Comparing Social Services' Collaborative Rationales across Different Welfare Regimes

Collaboration and networking are ubiquitous, versatile features of social service provision in most Western countries. However, it is an open question whether networking means and entails the same across countries. Comparing regulatory frameworks in three jurisdictions representing distinctive ‘worlds of welfare services’ – Germany, Norway and Quebec – this article aims at eliciting the normative rationales that underpin and inform local service networks in child welfare and protection (CWP) systems. In Norway, where services are little diversified and largely insular, networking appears as a way of opening up for greater organizational plurality, within and beyond the public sector realm. In Germany in contrast, where services are highly pluralized and fragmented, networks are seen as an instrument for streamlining complexity. As for Quebec – an intermediate case in some respects – networking is envisioned as a catalyst for aligning two co‐existing service streams and mitigating the child protection–family support divide. Interestingly, in all three places, networking is now being enforced through similar highly formalized, top‐down regulatory provisions, even though the intended directions of change differ markedly. This has implications for CWP policy as well as research on networks at large.     

Unemployment and economic security for young adults in Finland,Norway and Sweden: From unemployment protection to poverty relief

In this study, we investigated if there has been a displacement in the type and coverage of welfare services available for young unemployed adults in Finland, Norway and Sweden over the last two decades. This question is important because a number of studies have argued that the generous unemployment benefits and extensive labour market intervention found in the Nordic welfare states shield young people from the most severe consequences of economic inactivity. In this article, we instead show that during this period, less generous means‐tested unemployment and social assistance benefits have become the most important form of income protection for young people. In evidence, earnings‐related unemployment benefits now cover only 10 per cent of unemployed Swedes and Finns and 45 per cent of unemployed Norwegians aged 24 years or younger. This development marks a significant change in our understanding of unemployment protection for young people in Nordic countries.     

Experiencing Loneliness in Adolescence: A Matter of Individual Characteristics,Negative Peer Experiences,or Both?

The present study builds on the child‐by‐environment model and examines the joint contribution of intra‐individual characteristics (i.e., self‐esteem and shyness) and peer experiences (i.e., social acceptance, victimization, friendship quantity, and friendship quality) in the association with loneliness. A total of 884 adolescents (M_age = 15.80; 68 percent female) participated in this multi‐informant study. Results indicated that, in addition to self‐esteem and shyness, being poorly accepted by peers, being victimized, lacking friends, and experiencing poor‐quality friendships each contributed independently to the experience of loneliness. Further, friendship quantity and quality mediated the relation between the two intra‐individual characteristics and loneliness. Finally, a significant interaction was found between self‐esteem and social acceptance in predicting loneliness. The present study highlights the importance of investigating the joint effects of inter‐individual experiences and intra‐individual characteristics in examining loneliness. Suggestions to elaborate the child‐by‐environment model in loneliness research are discussed, and clinical implications are outlined.     

Gender and National Identity Constructions in the Cross‐Border Merger Context

In this article we explore ways in which vertical gender inequality is accomplished in discourse in the context of a recent chain of cross‐border mergers and acquisitions that resulted in the formation of a multinational Nordic company. We analyse social interactions of ‘doing’ gender in interviews with male senior executives from Denmark, Finland and Sweden. We argue that their explanations for the absence of women in the top echelons of the company serve to distance vertical gender inequality. The main contribution of the article is an analysis of how national identities are discursively (re)constructed in such distancing. New insights are offered to studying gender in multinationals with a cross‐cultural team of researchers. Our study sheds light on how gender intersects with nationality in shaping the multinational organization and the identities of male executives in globalizing business.     

Decision-making on social assistance in major cities in Sweden

It is desirable to strive for uniformity in decisions on social assistance. By presenting hypothetical new clients to social workers and asking for decisions, we investigated the occurrence of lack of agreement in decision-making. Surveys were made in Stockholm, Göteborg and Malmö. The results demonstrated variation in the assessment of applications for social assistance between the cities as well as within parts of the same city and between individual social workers in the same office. The reasons for these variations are discussed.
