Three estimators of the Mahalanobis distance in high-dimensional data

This paper treats the problem of estimating the Mahalanobis distance for the purpose of detecting outliers in high-dimensional data. Three ridge-type estimators are proposed and risk functions for deciding an appropriate value of the ridge coefficient are developed. It is argued that one of the ridge estimator has particularly tractable properties, which is demonstrated through outlier analysis of real and simulated data.     

‘Between heaven and hell’: Subjective well‐being of asylum seekers

Nearly 1.4 million asylum seekers arrived in Europe in 2015. With an unprecedented 822% increase in the number of asylum applicants, Finland experienced the largest increase in applicants than any other European country that year. In this study, we investigated asylum seekers’ experienced subjective well‐being (ExSWB) construct in comparison with their evaluated subjective well‐being (EvSWB) construct. A mixed methods approach with convergent design was adopted for the study, which combined quantitative data on asylum seekers’ (n = 181) ExSWB and EvSWB with qualitative data on the elements of ExSWB and EvSWB. The findings point at a limbus phase in asylum seekers’ livelihood transition between the borders for international protection in Finland. The Cantril self‐anchoring striving scale was used by the participants to describe this passage ritual of ambiguity. Furthermore, we also found gender differences related to coping and subjective well‐being, which supports previous findings on asylum seekers’ well‐being. Key Practitioner Message: ? The concept of the limbus phase of the asylum seeker livelihood transition is useful for describing asylum seekers’ experiences while waiting for an asylum decision; ? Asylum seeker SWB is closely related to status dissonance, separation and capitals, causing anxiety, worry and fear, and inflicting cognitive disruption; ? Equal, institutional‐level functions should be organised in the reception centre for easing the anxiety related to the asylum‐seeking process.     

Assimilation and participation in social assistance among immigrants

This article analyses assimilation and social assistance participation among immigrants in Sweden. Probit regressions are used in order to estimate the participation rates in social assistance among different groups of immigrants and native-born Swedes. The analysis is based upon panel data since the same individuals have been tracked in different years. The results show that among immigrants from the Nordic countries and from Western societies the participation rates are about the same as among comparable native-born Swedes. Immigrants from South European and non-European countries are over-represented in welfare usage. This over-representation remains even after controlling for differences in observable characteristics such as age, gender, family situation and educational attainment. Non-European immigrants assimilate out of welfare dependency at a faster rate than European immigrants, but despite this, non-European immigrants are over-represented in social assistance utilisation even after 20–25 years of residence in Sweden.     

Household allocation and spatial distribution in a market under (“soft”) rent control

We analyse whether segregation exists in the rental housing market in Stockholm, Sweden, a market under persistent and all-embracing, yet “soft”, rent control. We use segregation measures for the uncontrolled cooperative housing segment as benchmarks for analysing whether rent control counteracts segregation. We apply the analyses to a rich dataset encompassing some 400,000 households.     

The Receipt of Transfer Payments by Immigrants in Sweden

Using the native-born as a benchmark, this article examines the reliance of immigrants on Sweden's social safety net. Both in the raw data, and after conditioning on a number of explanatory variables, we find that there are differences between immigrants and natives regarding participation in the Swedish income security system. We also find that there are differences in this respect between immigrants from different regions as well as between more recent and earlier cohorts of immigrants. As regards unemployment insurance benefits and cash labour market assistance, no clear pattern can be discerned in the results. In the case of early retirement pension and social assistance, however, the picture looks different. Immigrants arriving at an early date from typical labour immigration regions are over-represented in early retirement. Immigrants, especially non-European immigrants with a recent date of arrival, are over-represented among recipients of social assistance. The overall conclusion is that the immigrants' total rate of participation in the income security system is determined by their rate of unemployment and their state of health. On the other hand, the distribution of their participation among the different components of the income security system is highly dependent on their length of residence in Sweden and where they come from.     

Usability and decision support systems in emergency management

The actors in charge of an emergency response are confronted with severe difficulties in coordination and decision making, especially in major accidents. To facilitate coordination, various decision support systems (DSS) integrated in communication systems have been developed. However, many DSS in the rescue service organizations are afflicted with under-use and other usability problems. Drawing on both a literature review and an analysis of recently obtained survey data from rescue personnel concerning usability of common communication system in Swedish emergency organizations, this paper addresses the issue of usability of DSS. It is concluded that the impetus for developing DSS in many cases has been the technological possibilities per se, not taking the decision makers task structure and contextual factors into account. It is argued that priority should be given to functions that provide a visual overview of the event and facilitate storing of the series of decisions made during the response.     

Ambivalence and Living Apart Together in Later Life: A Critical Research Proposal

Most unattached older persons who would like an intimate partnership do not want to remarry or be in a marriage‐like relationship. A growing trend is to live apart together (LAT) in an ongoing intimate relationship that does not include a common home. We address the debate about whether LAT constitutes a new form of intimate relationship in a critical assessment of research on LAT relationships that applies ambivalence and concepts from the life course perspective. We conclude that among older but not younger adults, LAT relationships are generally a stable alternative to living with a partner, negotiated in the context of current social institutions and arrangements. We propose research questions that address later life living apart together as an innovative alternative intimate relationship. We encourage comparative work on the unique challenges of later life living apart together, their implications for other family ties, and their connection to social and cultural arrangements.     

Young people’s everyday political talk: a social achievement of democratic engagement

Everyday political talk is an important democratic activity. Research on young people has focused on the role of talk in political socialization. The overall question in this study is: What encourages or impedes young people to participate in everyday political talk? Politics has been described as a potentially unsafe topic. The study investigates young people’s own experiences of conversations in families, peer groups, and social media. The study applies a social interactional approach and understands political talk as a social achievement, related to norms and the management of self-identities. It is based on a multimethod approach comprising individual interviews, group interviews, and diaries. The group consists of 23 high school students (aged 17–18). The results show that the engagement in political talk is sensitive to the social settings. Norms make political topics expected or best to avoid. The family and peer groups are potentially important context for friendly talk, argumentations, exploration of opinions, and identities. The participants are in general more reluctant to express opinions in social media. The fear of face-threatening responses is one important aspect. The study suggests that political talk is an activity in which young people express, reveal, and carefully manage political self-identities.     

Time Consistency of Fiscal and Monetary Policy: A Solution

This paper demonstrates how time consistency of the Ramsey policy—the optimal fiscal and monetary policy under commitment—can be achieved. Each government should leave its successor with a unique maturity structure for nominal and indexed debt, such that the marginal benefit of a surprise inflation exactly balances the marginal cost. Unlike in earlier papers on the topic, the result holds for quite general Ramsey policies, including time‐varying polices with positive inflation and positive nominal interest rates. We compare our results with those in Persson, Persson, and Svensson (1987), Calvo and Obstfeld (1990), and Alvarez, Kehoe, and Neumeyer (2004).     

Earnings Inequality and the Gender Gap: An Accounting Exercise for Sweden 1975–1991

Using the Household Income Survey, the earnings of full time, full year workers in Sweden are studied. Earnings inequality as well as the gender earnings gap were found to decrease up to the beginning of the 1980s, when both started to increase. The following questions are also addressed: How much has the changed earnigns gap contributed to changes in earnings inequality? How much should earnings inequality decrease in the case of men and women having the same mean income while keeping inequality within each gender category constant?
