In Utero Shocks and Health at Birth
Research on the effect of in utero shocks on health at birth may be influenced by in utero selection. This study outlines a conceptual framework and shows that the results of the standard empirical approach are biased if (i) the exposure changes the probability of fetal death and (ii) health differences exist between deceased and surviving fetuses. Furthermore, an empirical example is provided to illustrate the potential importance of fetal selec…
Heterogeneous impacts of climate change on morbidity
This paper examines the effect of temperature on emergency department (ED) visits using administrative data covering 50 % of the Hungarian population and 3.52 million ED visits from 2009 to 2017. The results show that ED visit rates increase when average temperatures exceed 10°C, primarily driven by mild cases that do not result in hospitalization. Higher humidity amplifies the heat effect, which is also stronger following consecutive hot days. T…
The Experiential Advantage in Consumption
Previous research indicates that individuals derive greater happiness from spending on experiences than on material possessions. However, these studies have relied primarily on U.S. samples and research designs in which participants directly rated their happiness with recalled purchases. This study examines whether the “experiential advantage” holds in a non-U.S. context, specifically among two samples from Hungary in East-Central Europe, which d…
Does the unemployment rate moderate the well‐being disadvantage of the unemployed? Within‐region estimates from the European Social Survey
Using pooled cross‐sectional data (eight waves of the European Social Survey), this work analysed how the regional unemployment rate influences the well‐being disadvantages of the unemployed. We estimate region fixed effects and slopes models that, unlike the standard region fixed effects approach, provide an unbiased estimate of the cross‐level interaction term (between being unemployed and the unemployment rate) in the absence of unobserved tim…
The effect of temperature on birth rates in Europe
Using data from 32 European countries for nearly 244 million live births between 1969 and 2021, this paper examines the effects of temperatures on birth rates. The results show that exposure to hot days slightly reduces birth rates five to eight months later, while much stronger negative effects are observed nine to ten months after exposure to hot temperatures. Thereafter, a partial recovery is observed, with slightly increased birth rates. This…
Temperature, climate change, and human conception rates
In this paper, we examine the relationship between temperature and human conception rates and project the impacts of climate change by the mid-twenty-first century. Using complete administrative data on 6.8 million pregnancies between 1980 and 2015 in Hungary, we show that exposure to hot temperatures reduces the conception rate in the first few weeks following exposure, but a partial rebound is observed after that. We project that with absent ad…
Temperature, climate change, and birth weight
We analyze the impact of in utero temperature exposure on the birth weight and an indicator for low birth weight using administrative data on singleton live births conceived between 2000 and 2016 in Hungary. We find that exposure to high temperatures during pregnancy decreases birth weight, but its impact on the probability of low birth weight is weaker. Exposure to one additional hot day (mean temperature > 25 °C) during the gestation period red…
Life expectancy inequalities in Hungary over 25 years
Using mortality registers and administrative data on income and population, we develop new evidence on the magnitude of life expectancy inequality in Hungary and the scope for health policy in mitigating this. We document considerable inequalities in life expectancy at age 45 across settlement-level income groups, and show that these inequalities have increased between 1991-96 and 2011-16 for both men and women. We show that avoidable deaths play…

Temperature, climate change, and birth weight
