Unintended Population Consequences of Policies

Unintended population consequences of policies stem from three sources: (1) A policy overshoots its original goal; (2) different policies conflict, so that the implementation of one policy inhibits implementation of another policy; (3) negative consequences of a policy are unforeseen, or are anticipated but judged unlikely to be severe or considered less important than the positive aims of the policy. Examples from Singapore, South Africa, Italy, the U.S., and the former Soviet Union are discussed.     

The Educational Consequences of Teen Childbearing

A huge literature shows that teen mothers face a variety of detriments across the life course, including truncated educational attainment. To what extent is this association causal? The estimated effects of teen motherhood on schooling vary widely, ranging from no discernible difference to 2.6 fewer years among teen mothers. The magnitude of educational consequences is therefore uncertain, despite voluminous policy and prevention efforts that rest on the assumption of a negative and presumably causal effect. This study adjudicates between two potential sources of inconsistency in the literature—methodological differences or cohort differences—by using a single, high-quality data source: namely, The National Longitudinal Study of Adolescent Health. We replicate analyses across four different statistical strategies: ordinary least squares regression; propensity score matching; and parametric and semiparametric maximum likelihood estimation. Results demonstrate educational consequences of teen childbearing, with estimated effects between 0.7 and 1.9 fewer years of schooling among teen mothers. We select our preferred estimate (0.7), derived from semiparametric maximum likelihood estimation, on the basis of weighing the strengths and limitations of each approach. Based on the range of estimated effects observed in our study, we speculate that variable statistical methods are the likely source of inconsistency in the past. We conclude by discussing implications for future research and policy, and recommend that future studies employ a similar multimethod approach to evaluate findings.     

Death at the Border: Efficacy and Unintended Consequences of US Immigration Control Policy

This article assesses the efficacy of the strategy of immigration control implemented by the US government since 1993 in reducing illegal entry attempts, and documents some of the unintended consequences of this strategy, especially a sharp increase in mortality among unauthorized migrants along certain segments of the Mexico–US border. The available data suggest that the current strategy of border enforcement has resulted in rechanneling flows of unauthorized migrants to more hazardous areas, raising fees charged by people‐smugglers, and discouraging unauthorized migrants already in the US from returning to their places of origin. However, there is no evidence that the strategy is deterring or preventing significant numbers of new illegal entries, particularly given the absence of a serious effort to curtail employment of unauthorized migrants through worksite enforcement. An expanded temporary worker program, selective legalization of unauthorized Mexican workers residing in the United States, and other proposals under consideration by the US and Mexican governments are unlikely to reduce migrant deaths resulting from the current strategy of border enforcement.     

Trajectories of Unintended Fertility

Having an unintended birth is strongly associated with the likelihood of having later unintended births. We use detailed longitudinal data from the Add Health Study (N = 8300) to investigate whether a host of measured sociodemographic, personality, and psychosocial characteristics select women into this “trajectory” of unintended childbearing. While some measured characteristics and aspects of the unfolding life course are related to unintended childbearing, explicitly modeling these effects does not greatly attenuate the association of an unintended birth with a subsequent one. Next, we statistically control for unmeasured time-invariant covariates that affect all birth intervals, and again find that the association of an unintended birth with subsequent ones remains strong. This persistent, strong association may be the direct result of experiencing an earlier unintended birth. We propose several mechanisms that might explain this strong association.     

The Lonely and Homeless: Causes and Consequences

Both, homelessness and loneliness are quite pervasive in North America. This study compared the causes of the loneliness experienced by the homeless to that of the general population. Two hundred and sixty six homeless and five hundred and ninety five men and women from the general population answered a 30 item yes/no questionnaire. The causes of loneliness were composed of the following five factors: Personal inadequacy, Developmental deficits, Unfulfilling intimate relationships, Relocation/significant separations, and Social marginality. The present results indicated that the causes of homeless loneliness are significantly different from those of the general population.

Unintended consequences of Immigration Reform: Discrimination and hispanic employment

The record-keeping requirements of the Immigration Reform and Control Act(IRCA), and fines for illegal employment, may induce employers to discriminate against foreign-appearing workers. The General Accounting Office (GAO) reported widespread IRCA-related discrimination but did not link reported discriminatory practices to discriminatory employment behavior. We analyze the GAO’s random survey and, controlling for selectivity effects, demonstrate that employers who report discriminatory practices actually employ fewer Hispanics. Although the measured reduction of Hispanic employment due to IRCA is fairly small, this finding parallels research alerting us to adverse consequences of a law that so far has achieved few of its intended effects.     

The Social Consequences of Insecure Jobs

Forms of insecure employment have been increasing all over Europe in recent decades. These developments have been welcomed by those who argued that these types of flexible employment would not only foster employment but could also help women, in particular, to positively combine work and family life. This vision was questioned by others who argued that flexible employment could have negative consequences for both occupational prospects and private and family life since it is often associated with greater insecurity and poorer working conditions. Relatively little research has been dedicated to the “social consequences” of insecure employment and its specific implications for work-life reconciliation issues. This paper contributes to this topic by linking research that addresses work-life conflict to the wider body of work dealing with job insecurity. It investigates the consequences of certain employment contracts on private and family life, taking into account information on current family life, future family plans and general well-being. It provides a series of test relating to the extent to which negative consequences in these areas might be attributable to the type of employment contract and how these vary between European countries. Analysis using ESS data from 2004 for western European countries confirms that insecure employment is accompanied by more problematic “social and family” situations. These negative consequences are partly shaped by the specific context provided by the country in question.

The Socioeconomic Consequences of Privatization: An Empirical Analysis for Europe

This paper analyses the dynamics of poverty in Italy and compares it with that in France, Spain and the UK. For this purpose, we use transition matrices of entry and exit poverty rates and quantify true state dependence through econometric techniques. The analysis exploits the longitudinal component of EU-SILC for the period 2009–2012. Estimation of dynamic random effects probit models shows that, in all countries, after controlling for individual heterogeneity and initial conditions, there is evidence of true state dependence. In comparative terms, when not accounting for regional disparities within countries, the degree of poverty persistence is highest in Italy and lowest in the UK. If regional effects are considered, the degree of poverty persistence in Italy is of the same order of magnitude as in France and Spain, but higher than in the UK. Our findings suggest that unlike other countries, in Italy regional disparities play an important role in explaining poverty state dependence.

The Predictive Validity of Subjective Mortality Expectations: Evidence From the Health and Retirement Study

Several recent studies suggest that individual subjective survival forecasts are powerful predictors of both mortality and behavior. Using 15 years of longitudinal data from the Health and Retirement Study, I present an alternative view. Across a wide range of ages, predictions of in-sample mortality rates based on subjective forecasts are substantially less accurate than predictions based on population life tables. Subjective forecasts also fail to capture fundamental properties of senescence, including increases in yearly mortality rates with age. To shed light on the mechanisms underlying these biases, I develop and estimate a latent-factor model of how individuals form subjective forecasts. The estimates of this model’s parameters imply that these forecasts incorporate several important sources of measurement error that arguably swamp the useful information they convey.     

农民养老方式与可行能力研究

农民的养老方式选择与他们实际具备的可行能力密不可分。这种可行能力取决于农村的经济状况、农民的生产方式、生活方式和制度环境。本文通过对我国目前农民生存状况的描述,通过农民对自己经历、体验讲述的分析,表明他们在处理参保问题上的行为逻辑与他人贴上的理性小农的标签完全不同。土地养老、子女养老并不是农民自愿选择的养老方式,而是迫不得已应对的结果。可行能力的缺乏使农民只能牺牲自己的长远利益而维持目前的生活状态。尽管对于农民不办理养老保险有各种各样的解释,但本文认为从可行能力解释农民的养老选择是一个不可忽视的视角。可行能力不仅包含着个人的能力而且与他们所处的社会位置密切有关。本文认为,国家长期以来的发展政策和社会政策与它的标的群体-农民之间的过大差距,最终形成了农村养老保政策运行低效及对农民养老选择的负面影响。     

The Unequal Consequences of Mass Incarceration for Children

A growing literature has documented the mostly deleterious intergenerational consequences of paternal incarceration, but less research has considered heterogeneity in these relationships. In this article, I use data from the Fragile Families and Child Wellbeing Study (N = 3,065) to estimate the heterogeneous relationship between paternal incarceration and children’s problem behaviors (internalizing behaviors, externalizing behaviors, and early juvenile delinquency) and cognitive skills (reading comprehension, math comprehension, and verbal ability) in middle childhood. Taking into account children’s risk of experiencing paternal incarceration, measured by the social contexts in which children are embedded (e.g., father’s residential status, poverty, neighborhood disadvantage) reveals that the consequences—across all outcomes except early juvenile delinquency—are more deleterious for children with relatively low risks of exposure to paternal incarceration than for children with relatively high risks of exposure to paternal incarceration. These findings suggest that the intergenerational consequences of paternal incarceration are more complicated than documented in previous research and, more generally, suggest that research on family inequality consider both differential selection into treatments and differential responses to treatments.     

The Proximate Determinants of Educational Homogamy: The Effects of First Marriage,Marital Dissolution,Remarriage, and Educational Upgrading

This paper adapts the population balancing equation to develop a framework for studying the proximate determinants of educational homogamy. Using data from the National Longitudinal Survey of Youth on a cohort of women born between 1957 and 1964, we decompose the odds of homogamy in prevailing marriages into four proximate determinants: (1) first marriages, (2) first and later marital dissolutions, (3) remarriages, and (4) educational attainment after marriage. The odds of homogamy among new first marriages are lower than among prevailing marriages, but not because of selective marital dissolution, remarriage, and educational attainment after marriage, as has been speculated. Prevailing marriages are more likely to be educationally homogamous than new first marriages because of the accumulation of homogamous first marriages in the stock of marriages. First marriages overwhelmingly account for the odds of homogamy in prevailing marriages in this cohort. Marital dissolutions, remarriages, and educational upgrades after marriage have relatively small and offsetting effects. Our results suggest that, despite the high prevalence of divorce, remarriage, and continued schooling after marriage in the United States, the key to understanding trends in educational homogamy lies primarily in variation in assortative mating into first marriage.     

The Weakening Position of University Graduates in Singapore's Labor Market: Causes and Consequences

Pulled along by global developments, Singapore is rapidly developing a “knowledge‐based economy.” Between 1990 and 2000, gross domestic product more than doubled (in constant dollars), and the number of managerial and professional jobs almost doubled. Such advances should be a boon to middle‐class Singaporeans, but, instead, they find themselves under increasing economic pressure despite the increased need for educated labor and the surplus of manual labor. On the basis of analysis of available data, the article documents the deteriorating relative position of the well‐educated in the labor market and explores the role of migration in that process.
