I am a Post-doc at the Department of Finance, Stockholm School of Economics and a researcher at the Institute for Social Research (SOFI), Stockholm University. I am a IZA research affiliate and a Distinguished CESifo Affiliate. I received my Ph.D. from Stockholm School of Economics in 2018.

I do research on inequality, education, and health, in applied microeconomics, using extensive individual-level datasets to to study the causes and consequences of important real-life decisions. My current work involves topics in college choice, social preferences, and household finance. I am also coordinating SWECOV, a large research program about the COVID-19 pandemic.

Work in Progress

  • Inheritance of fields of study

    Winner of the Distinguished CESifo Affiliate Award 2023.

    University graduates are more than three times as likely to hold a degree in the field their parent graduated from. To estimate how much of this association is caused by the educational choices of parents, I exploit admission thresholds to university programs in a regression discontinuity design. I study individuals who applied to Swedish universities between 1977 and 1992 and evaluate how their enrollment in different fields of study increases the probability that their children later study the same topic. I find strong causal influence. At the aggregate level, children become 50% more likely to graduate from a field if their parent has previously enrolled in it. The effect is positive for most fields, but varies substantially in size. Technology, engineering, medicine, business exhibit the largest, significant, effects. For these fields, parental enrollment increases child graduation probability with between 2.0 and 12.8 percentage points. I show that the parent's labor market experience plays an important role in explaining the results, but parental field enrollment does not increase subject-specific skills, nor is it associated with higher returns to earnings. I find little evidence for comparative advantage being the key driver of field inheritance. Rather, parents seem to function as role models, making their own field choice salient. This is indicated by the fact that children become less likely to follow parents with weak labor market prospects, and that children are more likely to follow the parent with the same gender.

  • Inequality and COVID-19 in Sweden: Relative risks of nine negative life events, along four social gradients, in pandemic vs. pre-pandemic years


    with Olof ÖstergrenEvelina Björkegren, and Torsten Persson

    The COVID-19 pandemic struck societies directly and indirectly, challenging not just people’s health but many aspects of life. But pandemic burdens fell more heavily on some groups than others. These different consequences of the spreading virus – and the measures to fight them – are reported and analyzed in different scientific fora, with hard-to-compare methods that largely follow disciplinary boundaries. As a result, it is hard to grasp the overall impact of the pandemic on inequality. This paper relies on individual-level, administrative data for Sweden’s entire population to describe how different social groups fared in terms of nine outcomes: three types of COVID-19 incidence, as well as six other negative life events. During 2020, the population faced severe morbidity and mortality from COVID-19 and saw higher all-cause mortality, income losses and unemployment risks, as well as reduced access to medical care. In terms of relative risks, these burdens fell disproportionately on those with low income or education, and on residents born outside of Sweden. In the pandemic, all-cause mortality, unemployment, substantial income loss, poor mental health, and reduced access to health care went up for all groups in Sweden. But relative risks across social groups were strikingly similar to those in pre-pandemic years.

  • Business Education and Portfolio Returns

    Draft available to download. Comments appreciated.

    We provide evidence of a positive causal link between financial knowledge acquired through business education and returns on stock investments. Using exogenous variation generated by admission thresholds to university business programs in Sweden, we document that early investments in financial sophistication causes individuals to invest significantly more in the stock market, to earn higher portfolio returns, and to end up accumulating higher levels of wealth. Investments in financial sophistication at the launch of economic life thus significantly alters the life cycle wealth profiles of individuals.

  • Nowcasting COVID-19 Statistics Reported with Delay: A Case-Study of Sweden and the UK

    IJERPH, 2023

    with Joacim Rocklöv and Jonas Wallin

    The COVID-19 pandemic has demonstrated the importance of unbiased, real-time statistics of trends in disease events in order to achieve an effective response. Because of reporting delays, real-time statistics frequently underestimate the total number of infections, hospitalizations and deaths. When studied by event date, such delays also risk creating an illusion of a downward trend. Here, we describe a statistical methodology for predicting true daily quantities and their uncertainty, estimated using historical reporting delays. The methodology takes into account the observed distribution pattern of the lag. It is derived from the “removal method”—a well-established estimation framework in the field of ecology.

  • O Brother, Where Start Thou? Sibling Spillovers on College and Major Choice in Four Countries

    Quarterly Journal of Economics, 2021

    with Andres Barrios-Fernandez 

    Family and social networks are widely believed to influence important life decisions, but causal identification of those effects is notoriously challenging. Using data from Chile, Croatia, Sweden, and the United States, we study within-family spillovers in college and major choice across a variety of national contexts. Exploiting college-specific admissions thresholds that directly affect older but not younger siblings’ college options, we show that in all four countries a meaningful portion of younger siblings follow their older sibling to the same college or college-major combination. Older siblings are followed regardless of whether their target and counterfactual options have large, small, or even negative differences in quality. Spillover effects disappear, however, if the older sibling drops out of college, suggesting that older siblings’ college experiences matter. That siblings influence important human capital investment decisions across such varied contexts suggests that our findings are not an artifact of particular institutional detail but a more generalizable description of human behavior. Causal links between the postsecondary paths of close peers may partly explain persistent college enrollment inequalities between social groups, and this suggests that interventions to improve college access may have multiplier effects.

  • Predicting the replicability of social science lab experiments

    PLOS One, 2019

    with Anna Dreber 

    We measure how accurately replication of experimental results can be predicted by black-box statistical models. With data from four large-scale replication projects in experimental psychology and economics, and techniques from machine learning, we train predictive models and study which variables drive predictable replication. The models predicts binary replication with a cross-validated accuracy rate of 70% (AUC of 0.77) and estimates of relative effect sizes with a Spearman ρ of 0.38. The accuracy level is similar to market-aggregated beliefs of peer scientists (Camerer et al., 2016; Dreber et al., 2015). The predictive power is validated in a pre-registered out of sample test of the outcome of Camerer et al. (2018), where 71% (AUC of 0.73) of replications are predicted correctly and effect size correlations amount to ρ = 0.25. Basic features such as the sample and effect sizes in original papers, and whether reported effects are single-variable main effects or two-variable interactions, are predictive of successful replication. The models presented in this paper are simple tools to produce cheap, prognostic replicability metrics. These models could be useful in institutionalizing the process of evaluation of new findings and guiding resources to those direct replications that are likely to be most informative.

  • Evaluating the replicability of social science experiments in Nature and Science between 2010 and 2015

    Being able to replicate scientific findings is crucial for scientific progress. We replicate 21 systematically selected experimental studies in the social sciences published in Nature and Science between 2010 and 2015. The replications follow analysis plans reviewed by the original authors and pre-registered prior to the replications. The replications are high powered, with sample sizes on average about five times higher than in the original studies. We find a significant effect in the same direction as the original study for 13 (62%) studies, and the effect size of the replications is on average about 50% of the original effect size. Replicability varies between 12 (57%) and 14 (67%) studies for complementary replicability indicators. Consistent with these results, the estimated true-positive rate is 67% in a Bayesian analysis. The relative effect size of true positives is estimated to be 71%, suggesting that both false positives and inflated effect sizes of true positives contribute to imperfect reproducibility. Furthermore, we find that peer beliefs of replicability are strongly related to replicability, suggesting that the research community could predict which results would replicate and that failures to replicate were not the result of chance alone.

  • Evaluating Replicability of Laboratory Experiments in Economics

    The replicability of some scientific findings has recently been called into question. To contribute data about replicability in economics, we replicated 18 studies published in the American Economic Review and the Quarterly Journal of Economics between 2011 and 2014. All of these replications followed predefined analysis plans that were made publicly available beforehand, and they all have a statistical power of at least 90% to detect the original effect size at the 5% significance level. We found a significant effect in the same direction as in the original study for 11 replications (61%); on average, the replicated effect size is 66% of the original. The replicability rate varies between 67% and 78% for four additional replicability indicators, including a prediction market measure of peer beliefs.

  • Using Prediction Markets to Forecast Research Evaluations

    The 2014 Research Excellence Framework (REF2014) was conducted to assess the quality of research carried out at higher education institutions in the UK over a 6 year period. However, the process was criticized for being expensive and bureaucratic, and it was argued that similar information could be obtained more simply from various existing metrics. We were interested in whether a prediction market on the outcome of REF2014 for 33 chemistry departments in the UK would provide information similar to that obtained during the REF2014 process. Prediction markets have become increasingly popular as a means of capturing what is colloquially known as the ‘wisdom of crowds’, and enable individuals to trade ‘bets’ on whether a specific outcome will occur or not. These have been shown to be successful at predicting various outcomes in a number of domains (e.g. sport, entertainment and politics), but have rarely been tested against outcomes based on expert judgements such as those that formed the basis of REF2014.
