The Impact of Children on Divorce Risks of Swedish Women

The purpose of this paper is to study the impact of children on divorce risks in 1971–1994 for first-married Swedish women. This impact is examined using two measures of family composition, namely the number of children and the age of the youngest child, and we find an independent effect from each of these factors on the propensity to divorce. There is an additional impact of births prior to marriage on the subsequent divorce risk. We present time series of divorce risks for women with different types of children, showing trends for both the factors of parity and age of youngest child. The general picture of Swedish divorce-risk trends shows a strong increase in 1974, mostly among childless women, in response to a reform of the divorce legislation. Since the beginning of the 1980s, the risks have increased steadily, mostly among mothers. Our study is performed by indirect standardization of register data and we also control for the effects of age at and duration of marriage.     

A Note on Immigrant Representation in Temporary Agency Work and Self‐employment in Sweden

Abstract. This is a note on the immigrant representation in two forms of atypical employment in Sweden: self‐employment and temporary agency work. The employment rate among non‐western immigrants is substantially lower than among natives and using register data for the population in Sweden who were employed in 1999, we find that immigrants are over‐represented in both these forms of atypical employment. Immigrants from Asia are over‐represented in both forms of employment, whereas immigrants from South America are over‐represented among temporary agency workers but underrepresented among the self‐employed. These findings can be interpreted as an indication of that temporary agency work and self‐employment are used as alternatives to regular employment by groups in which unemployment is high.     

Return to work still possible after several years as a disability pensioner due to musculoskeletal disorders: a population-based study after new legislation in Sweden permitting "resting disability pension"

Different strategies have been used to stimulate a return to work (RTW) among individuals suffering from long-term ailments. In Sweden a new law on "resting disability pension" permits disability pensioners to go back to work without jeopardising their benefits. In this study different variables related to RTW during 2000 by means of this legislation were identified among disability pensioners with musculoskeletal disorders. Individuals in the study group, when compared to a control group, had more often been disability pensioners for several years, had additional education, estimated their previous job to have been physically strenuous to a lesser degree, were more satisfied with the treatment at the social insurance office and had a more positive self-image. This study shows that it may be meaningful to continue/resume rehabilitation efforts and to try to motivate an individual suffering from musculoskeletal disorders to return to work even after several years as a disability pensioner.     

A maximum-likelihood estimator with infinite error

The standard error of the maximum-likelihood estimator for 1/μ based on a random sample of size N from the normal distribution N(μ,σ²) is infinite. This could be considered to be a disadvantage.Another disadvantage is that the bias of the estimator is undefined if the integral is interpreted in the usual sense as a Lebesgue integral. It is shown here that the integral expression for the bias can be interpreted in the sense given by the Schwartz theory of generalized functions. Furthermore, an explicit closed form expression in terms of the complex error function is derived. It is also proven that unbiased estimation of 1/μ is impossible.Further results on the maximum-likelihood estimator are investigated, including closed form expressions for the generalized moments and corresponding complete asymptotic expansions. It is observed that the problem can be reduced to a one-parameter problem depending only on , and this holds also for more general location-scale problems. The parameter can be interpreted as a shape parameter for the distribution of the maximum-likelihood estimator.An alternative estimator is suggested motivated by the asymptotic expansion for the bias, and it is argued that the suggested estimator is an improvement. The method used for the construction of the estimator is simple and generalizes to other parametric families.The problem leads to a rediscovery of a generalized mathematical expectation introduced originally by Kolmogorov [1933. Foundations of the Theory of Probability, second ed. Chelsea Publishing Company (1956)]. A brief discussion of this, and some related integrals, is provided. It is in particular argued that the principal value expectation provides a reasonable location parameter in cases where it exists. This does not hold generally for expectations interpreted in the sense given by the Schwartz theory of generalized functions.     

Childbearing after Migration: Fertility Patterns of Foreign‐born Women in Sweden1

The present study provides an investigation of patterns in childbearing among foreign‐born women in Sweden from the 1960s to the 1990s. Event‐history techniques are applied to longitudinal population register data on childbearing and migration of 446,000 foreign‐born women who had ever lived in Sweden before the end of 1999. Period trends in parity‐specific fertility appear to be quite similar for Swedish‐ and foreignborn women, but important differences exist in levels of childbearing propensities between women from different countries of origin. Most immigrant groups tend to display higher levels of childbearing shortly after immigration. We conclude that migration and family building in many cases are interrelated processes and that it is always important to account for time since migration when fertility of immigrants is studied.     

The Impact of Labour-Force Participation on Childbearing Behaviour: Pro-Cyclical Fertility in Sweden during the 1980s and the 1990s

During the last two decades, Sweden has experienced strong fluctuations both in its economy and in its level of childbearing. A period of high employment and increasing fertility has been followed by a period of lower employment and decreasing fertility since the beginning of the 1990s. In this paper, we use register data for Swedish women in order to examine how various types of attachment to the labour market affect women's propensity to give birth at different parities. Specifically, we show what impact changes in women's employment status have had on recorded fertility trends in Sweden. We find that women who have relatively low levels of income and women who are enrolled as students generally have lower fertility than other women. We also find that a rise in the number of women with such characteristics can explain part of the decrease in fertility during the 1990s. It is evident, however, that other factors, working at the macro level, also have to be considered when one wants to explain the fluctuating fertility of Sweden. Social policy is one such factor. In sum, we find a pattern of pro-cyclical fertility, where levels of female earnings are positively related to levels of childbearing.

Analysis of rounded exponential data

The problem of inference based on a rounded random sample from the exponential distribution is treated. The main results are given by an explicit expression for the maximum-likelihood estimator, a confidence interval with a guaranteed level of confidence, and a conjugate class of distributions for Bayesian analysis. These results are exemplified on two concrete examples. The large and increasing body of results on the topic of grouped data has been mostly focused on the effect on the estimators. The methods and results for the derivation of confidence intervals here are hence of some general theoretical value as a model approach for other parametric models. The Bayesian credibility interval recommended in cases with a lack of other prior information follows by letting the prior equal the inverted exponential with a scale equal to one divided by the resolution. It is shown that this corresponds to the standard non-informative prior for the scale in the case of non-rounded data. For cases with the absence of explicit prior information it is argued that the inverted exponential prior with a scale given by the resolution is a reasonable choice for more general digitized scale families also.
