How Robust Are Country Rankings in Educational Mobility?

We investigate the impact of analytical choices on country comparisons in intergenerational educational mobility using a multiverse approach. A literature survey gives rise to 2,880 plausible ways of measuring educational mobility, which we apply to European Social Survey data from 16 countries. Although some countries consistently appear at the top or bottom of the mobility rankings, most show substantial variation. Beyond our methodological contribution, we report two substantive findings. First, some countries often characterized as low-mobility emerge as matching or surpassing the egalitarian Nordic countries, reinforcing the view that wider mobility differences cannot be attributed solely to the education system but must be sought elsewhere, such as the labor market. Second, the choice of parameter—such as regression coefficients, correlations, or categorical measures—is the single most influential factor that shifts country rankings. As different parameters carry distinct theoretical meanings, researchers should treat parameter choice not merely as a robustness check but as an opportunity to test and refine competing theories.

Yes, Denmark Is a More Educationally Mobile Society than the United States: Rejoinder to Kristian Karlson

Stefan B. Andrade, Jens-Peter Thomsen

In this rejoinder to Kristian Bernt Karlson (KBK), we maintain that there are substantial differences in intergenerational educational mobility between Denmark and the United States. In fact, when we include additional parental information from the National Longitudinal Survey of Youth 1997 (NLSY97) for the United States, as suggested by KBK, the gap between Denmark and the United States increases. To confirm our findings, we show that the same conclusion about markedly higher educational mobility in Denmark holds when data from the General Social Survey are substituted for the NLSY97.

Is Denmark a Much More Educationally Mobile Society than the United States? Comment on Andrade and Thomsen, "Intergenerational Educational Mobility in Denmark and the United States" (2018)

Kristian Bernt Karlson

I evaluate Andrade and Thomsen (A&T)’s (2018) study, which concludes that Denmark is significantly more educationally mobile than the United States. I make three observations. First, A&T overstate the difference in educational mobility between Denmark and the United States. Both in international comparison and compared with differences in intergenerational income mobility, A&T’s reported country differences in educational mobility are negligible. For example, whereas income mobility estimates reported in the literature differ by 300 to 600 percent between the two countries, the corresponding educational mobility estimates that A&T report differ by 10 to 20 percent. Second, I provide evidence suggesting that A&T’s use of crude categorical education measures leads them to overstate these negligible differences. Third, A&T’s empirical analyses of the U.S. data contain several statistical and data-related flaws, some so severe that they potentially undermine the credibility of their analyses. In sum, A&T’s results are perfectly consistent with the existence of a mobility paradox very similar to what Sweden–United States comparisons show: although Denmark and the United States are dissimilar with respect to income mobility, they are similar with respect to educational mobility. Understanding the nature of this paradox should be a key concern for future mobility research.

American Exceptionalism Revisited: Tax Relief, Poverty Reduction, and the Politics of Child Tax Credits

Joshua T. McCabe, Elizabeth Popp Berman

Sociological Science, July 8, 2016
DOI 10.15195/v3.a24

In the 1990s, several liberal welfare regimes (LWRs) introduced child tax credits (CTCs) aimed at reducing child poverty. While in other countries these tax credits were refundable, the United States alone introduced a nonrefundable CTC. As a result, the United States was the only country in which poor and working-class families were paradoxically excluded from these new benefits. A comparative analysis of Canada and the United States shows that American exceptionalism resulted from the cultural legacy of distinct public policies. We argue that policy changes in the 1940s institutionalized different “logics of appropriateness” that later constrained policymakers in the 1990s. Specifically, the introduction of family allowances in Canada and other LWR countries naturalized a logic of income supplementation in which families could legitimately receive cash benefits without the stigma of “welfare.” Lacking this policy legacy, American attempts to introduce a refundable CTC were quickly derailed by policymakers who saw it as equivalent to welfare. Instead, they introduced a narrow, nonrefundable CTC under the alternative logic of “tax relief,” even though this meant excluding the lowest-income families. The cultural legacy of past policies can explain American exceptionalism not only with regard to CTCs but to other social policies as well.

The Missing Main Effect of Welfare State Regimes: A Replication of ‘Social Policy Responsiveness in Developed Democracies’ by Brooks and Manza

Nate Breznau

Sociological Science, August 17, 2015
DOI 10.15195/v2.a20

This article reports the results of a replication of Brooks and Manza’s “Social Policy Responsiveness in Developed Democracies” published in 2006 in the American Sociological Review. The article finds that Brooks and Manza utilized an interaction term but excluded the main effect of one of the interacted variables. This model specification has specific implications: statistically, that the omitted main effect variable has no correlation with the residual error term from their regression; theoretically speaking, this means that all unobserved historical, cultural, and other characteristics that distinguish liberal democratic welfare regimes from others can be accounted for with a handful of quantitative measures. Using replicated data, this article finds that the Brooks and Manza models fail these assumptions. A sensitivity analysis using more than 800 regressions with different configurations of variables confirms this. In 99.5 percent of the cases, addition of the main effect removes Brooks and Manza’s empirical findings completely. A theoretical discussion illuminates why these findings are not surprising. This article provides a reminder that models and theories are coterminous, each implied by the other.

Disability and the Worlds of Welfare Capitalism

Rourke O’Brien

Sociological Science, January 12, 2015
DOI 10.15195/v2.a1

A higher proportion of working- age persons receive disability assistance in the Nordic countries and the Netherlands than in other European countries. Whereas current research emphasizes the connection between disability assistance and rates of labor force exit, to date there has been no exploration of how welfare state context influences individual self-reported disability. Using nationally representative data from 15 countries (n = 88, 478), I find that residents of generous welfare states are significantly more likely to report a disability net of self-reported health, sociodemographic, and labor force characteristics and, notably, that this association extends to younger and more educated workers. I argue that welfare state context may directly shape what it means to be disabled, which may have consequences for evaluations of welfare state performance and social exclusion.
