High-stakes national testing, gender and school stress in Europe – A difference-in-difference analysis.

Björn Högberg – Dániel Horn

2021/11

Outcomes related to the wellbeing of students are increasingly being recognized as valuable objectives for education systems. In this study, we ask if high-stakes testing affects school-related stress among students and if there are gender differences in these effects.

We combine macro-level data on high-stakes testing with survey data on more than 300,000 students aged 10-16 years in 31 European countries, from three waves (2002, 2006 and 2010) of the Health Behaviour in School-aged Children (HBSC) study. With variation in high-stakes testing across countries, years and grade levels, we use a quasi-experimental difference-in-differences (DD) design for identification of causal effects.

We find that high-stakes testing increases self-reported school-related stress by almost 10 % of a standard deviation. This is primarily driven by a strong effect for girls, meaning that high-stakes testing increases the gender gap in school-related stress. The results are robust to a range of sensitivity analyses.

Versengeni és együttműködni? Egy reprezentatív felmérés tanulságai

KHAYOUTI SÁRA –KISS HUBERT JÁNOS –HORN DÁNIEL

2021/10

Ebben a tanulmányban azt vizsgáljuk két reprezentatív felmérés segítségével, hogy egyéni szinten hogyan viszonyul egymáshoz a versengés és az együttműködés, illetve ezek hogyan függnek össze a végzettséggel. Az első eredményünk az, hogy a versengés és az együttműködés pozitívan és szignifikánsan korrelál, még akkor is, ha figyelembe vesszük a válaszadó korát, nemét, a lakhelyének településtípusát és a régióját. Másrészt azt találjuk, hogy a versengés és az együttműködés nemlineárisan függ össze a végzettséggel. Magasabb fokú versengés és együttműködés több oktatásban töltött évvel jár együtt, de egyre csökkenő mértékben. Továbbá, a túl magas együttműködés és versengési értékkel a végzettség alacsonyabb szintje jár együtt.

Introducing flexible retirement : a dynamic model

ANDRÁS SIMONOVITS

2021/9

Typically economists arguing for flexible (or variable) retirement age, but they rely on steady state analysis.  In this paper we consider the replacement of a mandatory retirement system with a flexible one in real time. We show that even if early retirement is duly punished, diminishing the effective retirement age by 1 year raises the first year’s and the total expenditures during transition by 8% and  70% of the original annual expenditure, respectively.

Statisztikai jelentés a gyermekegészség állapotáról Magyarországon a 21. század második évtizedében

HAJDU TAMÁS – KERTESI GÁBOR

2021/8

ÖSSZEFOGLALÓ

Kutatásunk a magyarországi gyerekek egészségi állapotában fennálló társadalmi különbségeket vizsgálja a 2010-es években. Az elemzések alapját számos adminisztratív adatbázis és survey jellegű információforrás adja. Beszámolónk összegyűjti, egységes statisztikai keretbe rendezi a rendelkezésre álló mikroszintű adatok többségét, és a laikus közvélemény számára is követhető formában értelmezi őket. A vizsgálatunk rámutat arra, hogy gyermekek egészsége milyen nagy mértékben függ össze azzal, hogy milyen társadalmi közegbe születtek, hogy milyen életkörülmények és jövedelmi viszonyok között élnek, illetve hogy milyen viselkedési sajátosságokkal rendelkeznek ők maguk és a szüleik.

Time patterns of precautionary health behaviours during an easing phase of the COVID-19 pandemic in Europe

ANIKÓ BÍRÓ – RÉKA BRANYICZKI – PÉTER ELEK

2021/7

Using data from the COVID-19 questionnaire of the Survey of Health, Ageing and Retirement in Europe (SHARE), we investigate the time patterns of precautionary health behaviours of individuals aged 50 and above during the summer of 2020, an easing phase of the COVID-19 pandemic in Europe. We also examine how these health behaviours differ by the presence of chronic conditions such as hypertension, high cholesterol level, heart disease, diabetes or chronic bronchitis, which can be considered as risk factors for COVID-19. Our results suggest that while on average, people became less precautious during our analysed time period, this is less so for those who are at higher risk. We also document large regional differences in precautionary health behaviours and show that higher risk individuals are on average more cautious in all regions. We conclude that people adjusted their health behaviours in line with the generally understood risk of the COVID-19 disease. At the same time, our results also point out divergences in the level of willingness to take different precautionary steps.

Ranking Institutions within a Discipline: The Steep Mountain of Academic Excellence

BALÁZS R. SZIKLAI

2021/6

We present a novel algorithm to rank smaller academic entities such as university departments or research groups within a research discipline. The Weighted Top Candidate (WTC) algorithm is a generalisation of an expert identification method. The axiomatic characterisation of WTC shows why it is especially suitable for scientometric purposes. The key axiom is stability — the selected institutions support each other’s membership. The WTC algorithm, upon receiving an institution citation matrix, produces a list of institutions that can be deemed experts of the field. With a parameter we can adjust how exclusive our list should be. By completely relaxing the parameter, we obtain the largest stable set — academic entities that can qualify as experts under the mildest conditions. With a strict setup, we obtain a short list of the absolute elite. We demonstrate the algorithm on a citation database compiled from game theoretic literature published between 2008–2017. By plotting the size of the stable sets with respect to exclusiveness, we can obtain an overview of the competitiveness of the field. The diagram hints at how difficult it is for an institution to improve its position.

The Role of the Gender Composition of Performance Feedback on Peers in Shaping Persistence and Performance

SÁNDOR KATONA - ANNA LOVÁSZ

2021/5

We study the impact of the gender composition of a scoreboard on the persistence and performance of players in an online game. Players were randomly selected into eight groups, defined along two dimensions: they saw high or average scores on a scoreboard (score level), and within each of these, they saw either 3 male, 2 male and one female, 1 male and 2 female, or 3 female names associated with the scores (gender composition). Based on 1140 participants, we find that males are generally less responsive to performance information on other participants. Compared to the baseline of all male names on the scoreboard, females play fewer games when they see only female names, but more games when they see mixed gender names with high scores. Their performance (best score) increases significantly when they see at least one female name and high scores. This result is in line with the importance of female-specific reference points – or role models – in encouraging females’ participation and higher performance in competitive settings. It supports the use of policies aimed at providing these, such as the introduction of female role models and the public acknowledgement of high performing females.

Post-conception heat exposure increases clinically unobserved pregnancy losses

TAMÁS HAJDU – GÁBOR HAJDU

2021/4

Evidence of the relationship between temperature during pregnancy and human embryo mortality is limited. Most importantly, the literature lacks causal estimations and studies on early pregnancy losses. Here, we estimate the impact of early pregnancy temperature exposure on the clinically unobserved pregnancy loss rate. We use administrative data of clinically observed pregnancies from more than three decades for Hungary. We apply an empirical approach that allows us to infer the impact of temperature on the clinically unobserved pregnancy loss rate from the estimated effects on the clinically observed conception rate. The results show that exposure to hot temperatures during the first few weeks after the conception week increases the clinically unobserved pregnancy loss rate, whereas exposure to colder temperatures seems to decrease it. Importantly, the temperature-induced changes represent changes in the total number of pregnancy losses rather than a compositional change between clinically observed and clinically unobserved pregnancy losses.

Gender differences in preferences of adolescents: evidence from a large-scale classroom experiment

DÁNIEL HORN – HUBERT JÁNOS KISS – TÜNDE LÉNÁRD

2021/3

In this study, we estimate unadjusted and adjusted gender gap in time preference, risk attitudes, altruism, trust, trustworthiness, cooperation and competitiveness using data on 1088 high-school students from 53 classes. These data, collected by running incentivized experiments in Hungarian classrooms, are linked to an administrative data source on the students’ standardized test scores, grades and family background. We find that after taking into account class fixed effects, females are significantly more altruistic (both with classmates and schoolmates), but are less present-biased, less risk tolerant, less trusting, less trustworthy and less competitive than males. At the same time we do not observe significant gender differences in patience, time inconsistency and cooperation at the 5% significance level. We also show that these initial gender differences do not change even if we control for age, family background, cognitive skills and school grades in a regression framework. Moreover, the gender gap also remains in all but one of these preferences even if we control for the other preference domains, suggesting that only risk preferences are confounded by the other preferences, at least as the gender gap in these preferences is concerned.

Gender Differences in the Skill Content of Jobs

RITA PETŐ – BALÁZS REIZER

2021/2

There is significant heterogeneity in actual skill use within occupations even though occupations are differentiated by the tasks workers should perform during work. Using data on 12 countries which are available both in the Programme for the International Assessment of Adult Competencies survey and International Social Survey Program, we show that women use their cognitive skills less than men even within the same occupation. The gap in skill intensity cannot be explained by differences in worker characteristics or in cognitive skills. Instead, we show that living in a partnership significantly increases the skill use of men compared with women. We argue that having a partner affects skill use through time allocation as the gender penalty of partnered women is halved once we control for working hours and hours spent on housework. Finally, we do not find evidence of workplace discrimination against women.

Competition , Subjective Feedback, and Gender Gaps in Performance

ANNA LOVÁSZ - BOLDMAA BAT-ERDENE EWA CUKROWSKA-TORZEWSKA - MARIANN RIGÓ ÁGNES SZABÓ-MORVAI

2021/1

We study gender differences in the impacts of competition and subjective feedback, using an online game with pop-up texts and graphics as treatments. We define 8 groups: players see a Top 10 leaderboard or not (competitiveness), and within these, they receive no feedback, supportive feedback, rewarding feedback, or „trash talk” (feedback type). Based on 5191 participants, we find that competition only increases the performance of males. However, when it is combined with supportive feedback, the performance of females also increases. This points to individualized feedback as a potential tool for decreasing gender gaps in competitive settings such as STEM fields.

Az ingázási időre ható tényezők és változásuk 1990 és 2011 között Magyarországon

BAKÓ TAMÁS – KÁLMÁN JUDIT

2020/57

Az ingázással töltött idő hatással lehet a munkakínálatra és nagymértékben befolyásolja az egyén jólétét. Jelen tanulmányunk egyik legjelentősebb eredménye, hogy míg a nemzetközi irodalom szerint a férfiak és a nők ingázása közötti időben mutatkozó különbség stabil, addig Magyarországon a vizsgált időszakban ez nem volt igaz: az adatok arra engednek következtetni, hogy a nők egyre jobban felzárkóztak a férfiakhoz mind a foglalkoztatás esélyében, mind az ingázási időben, illetve a megtett távolságban. Számos egyéni, valamint a helyi munkaerőpiacot jellemző változó hatását vizsgáltuk, ám eredményeink szerint a lakóhely földrajzi elhelyezkedése lényegesen nagyobb hatással bír az ingázási időre, mint bármelyik egyéni szintű változó (kivéve a foglalkozás). A Közép-magyarországi régióban lakókhoz képest az ország bármelyik másik régiójában lakók napi 17–30 perccel rövidebb ingázási idővel számolhatnak, ami komoly kihatással lehet az ingázás társadalmi költségeire és jóléti hatásaira.
