Lazuka, V. 2023. Household and individual economic responses to different health shocks: The role of medical innovations. IZA Working Paper 16226.

Abstract: This study provides new evidence regarding the extent to which medical care mitigates the economic consequences of various health shocks for the individual and a wider family. To obtain causal effects, I focus on the role of medical scientific discoveries and leverage the longitudinal dimension of unique administrative data for Sweden. The results indicate that medical innovations strongly mitigate the negative economic consequences of a health shock for the individual and create spillovers to relatives. Such mitigating effects are highly heterogeneous across prognoses. These results suggest that medical innovation substantially reduces the burden of welfare costs yet produces income inequalities.

Lazuka, V., Bengtsson, P., and Svensson, P. 2023. The causal effects of enclosures on production and productivityIZA Working paper 16394.

Abstract: Enclosures enforced private property rights at the onset of industrialization, yet numerous estimations of the enclosures’ effects on production and productivity rely on non-experimental designs. We estimate the causal effects of enclosure reforms applying state-of-the-art difference-in-differences and event-study methods to a large panel of farms observed between 1781 and 1865 in Sweden. Our results demonstrate that enclosures led to a 3.4 percent annual growth in land productivity in the first decade and overall production increase reached 82 percent after 30 years. Such results are much larger than previous estimates, suggesting that land enclosures were a prerequisite for modern economic growth..

Lazuka, V., Elwert, A. 2023. Life-cycle effects of comprehensive sex education. IZA Working paper Media: IZA Commentary

Abstract: Sex education can impact pupils’ sexual activity and convey the social norms regarding family formation and responsibility, which can have significant consequences to their future. To investigate the life-cycle effects of social norm transmission, this study draws on the introduction of comprehensive sex education in the curriculum of Swedish primary schools during the 1940s to the 1950s. Inspired by social-democratic values, sex education during this period taught students about abstinence, rational family planning choices, and the importance of taking social responsibility for their personal decisions. The study applies a state-of-the-art estimator of the difference-in-differences method to various outcomes of men and women throughout the life cycle. The results show that the reform affected most intended outcomes for men and women, ultimately decreasing gender inequality in earnings. The effects of the reform also extended to the succeeding generation of girls, encouraging them to choose a profession with prosocial responsibilities and engage in entrepreneurship. The findings suggest that social norms, internalized through school-based sex education, shape lifetime outcomes of individuals and their children in significant ways.

Lazuka, V. and Jensen, P. 2023. Multigenerational effects of smallpox vaccination. IZA Working paper

Abstract: Can the effect of a positive health shock, such as childhood vaccination, transmit across three generations? To answer this question, we estimate the impact of smallpox vaccination in childhood on the longevity and occupational achievements of three generations using unique individual-level data from Sweden, covering the last 250 years. We apply different estimation strategies based on linear and non-linear probability models. To address endogeneity concerns, we construct a shift-share instrumental variable, utilizing the fact that vaccination in Sweden was administered by the low-skilled clergy, who otherwise did not perform public health duties. Overall, our results show that a positive shock to the health of the first generation, such as smallpox vaccination, operating through various channels, enhances both health and socio-economic outcomes for at least two more generations.
