Chowdhury, Sutter and Zimmermann (2022) assessed the risk, time, and social preferences of family members in rural Bangladesh, presenting two main findings. First, there is a strong and positive association between family members’ preferences, even when controlling for personality traits and family background. Second, families can be grouped into two clusters: approximately 20% of the families are characterized by relatively impatient, risk-averse, and spiteful members, while the rest of the families have relatively patient, risk-tolerant, and prosocial members. Recognizing the pivotal role of cluster analysis in deriving the second result, we first successfully computationally reproduced the results, and then we conducted two types of robustness checks. The first examines the transformation of variables (continuous or categorical), affecting the proximity measure that is crucial to cluster analysis. The second assesses the effect of varying the number of clusters on the findings. Some results are robust, as we consistently find the small cluster of families identified by Chowdhury et al. (2022). However, divergent outcomes emerge with categorical variables (a logical choice given their nature) and a larger number of clusters (3 or 4). We conclude that, although the cluster analysis by Chowdhury et al. (2022) is valid, its outcomes significantly depend on the researcher’s assumptions and choices. Careful consideration of several alternatives is essential in exploratory cluster analysis to identify stable groups.

The linguistic-savings hypothesis posits that the grammatical marking of future events in languages is linked to future-oriented behavior. Recent experimental studies have suggested patience as a possible mechanism connecting language use and future-oriented behavior by exogenously manipulating what language is used. Our paper explores the association between patience and the language that people naturally use, thereby building on endogenous (as opposed to exogenously manipulated) language use. To capture natural language usage, we utilized a novel sentence-completion task designed for native speakers of the Hungarian language. This language allows for referencing future events through both present and future tenses. We hypothesized a positive correlation between being patient and using the present tense to refer to future events. We conducted incentivized and non-incentivized experiments with four independent samples of high school and university students, involving nearly 3,500 students in total. We find no consistent evidence that patience is correlated with endogenous future-time reference. Our null finding is further supported by a robustness check that leverages specific randomness in our data.

This paper investigates how the type of home environment – family foster care or residential care – affects the adult outcomes of individuals who were raised in state care during adolescence. While it is established in the literature that living in residential care is detrimental for babies, the effect of living in different types of care as an older child is underexplored. We use Hungarian individual-level administrative panel data and follow the children from age 13 until age 19. We show that the adult outcomes of adolescents who grew up in a foster family are substantially better even after controlling for a rich set of variables, including indicators of cognitive and non-cognitive skills, and mental problems observed at age 13. Young adults who grew up in family foster care are 8 percentage points more likely to complete secondary education, and 11 percentage points less likely to spend at least 6 months without either working or studying at age 19, than comparable peers raised in residential care. Using mental health medication is 5 percentage points less likely. For girls, the probability of teenage birth and abortion are smaller by 12 percentage points each. IV estimations using local foster mother capacity as an instrument reinforce the beneficial effect of family foster care.

In Hungary, initial pensions are indexed to average net wages, reported by official earnings statistics (ES), which does not cover the economy as whole. However, there is alternative statistical source on labour income, the national accounts (NA), intended to cover the total economy. The latter indicate a markedly lower rate of growth in wages than the ES for the period between 2010 and 2020 (4.9 vs. 1.9 percent increase in real gross wages per year). Relying on feasibility tests, we show that the rapid increase reported by the ES cannot, while the milder growth shown by the NA can be reconciled with relevant macroeconomic developments, e.g., changes in productivity and household consumption. We, therefore, claim that the ES overstated the actual increase in wages at the national level during the 2010s, and make our own calculations regarding the path of net wages and implied (hypothetical) initial pensions. The main implications of this exercise are the following: (i) the actual increase in initial benefits (linked to net wages, as reported by the ES) was excessive; (ii) in our estimate, the ratio of average benefits to average net wages did not fall by the extent shown by official statistics (the former is linked to the increase in prices, rather than that of wages). Moreover, (iii) the accumulation of major tensions between cohorts retiring in subsequent years might have been reduced by relying on the more plausible wage statistics reported by the NA, and by taking into account the impact of the dramatically reduced social contribution rate (paid by employers) in calculating initial benefits.

John von Neumann (Budapest, 1903–Washington D.C., 1957) was an exceptional polymath, who made fundamental contributions to mathematical logics, functional analysis, quantum mechanics, game theory, computer architecture and automata theory. In this brief paper, I shall review the game-theoretic results of von Neumann and their legacy in an informal way.
