WP522. Intra-Household Relative Income and Happiness: The Role of Unpaid Work Division During COVID and Afterwards

Rising female employment and earnings have transformed partners’ economic positions, while gender divisions in unpaid labor persist. The COVID-19 pandemic disrupted the organization of paid and unpaid work, opening a window to reassess these two dimensions within couples. Using longitudinal panel data from Poland (2021–2024), this paper examines how relative income and the division of unpaid labor relate to both life satisfaction and partner satisfaction among partnered adults. Random-effects models reveal distinct gendered patterns. For men, these dynamics are associated primarily with global life satisfaction: men report higher life satisfaction when they out-earn their partners, but substantially lower life satisfaction when they are out-earned and primarily responsible for domestic work. For women, effects concentrate in partner satisfaction: women who out-earn their partners report lower partner satisfaction when they also perform most domestic labor. These patterns hold for both housework and childcare and are observed primarily in the post-pandemic period.

WP464. Industrial robots and workers’ well-being in Europe

In the 21st century, advancements in technologies such as industrial robots have raised concerns about their impact on employment and wages, prompting extensive research. However, their effects on workers’ subjective well-being remain underexplored. This study addresses this gap ¬by examining whether workers experience a decline in well-being due to a loss of agency or maintain it by leveraging human skills to adapt to automation. Using data from the International Federation of Robotics, Eurostat, and the European Social Survey (2002–2018), we link robot density at the country-industry-year level to workers’ life satisfaction, happiness, job influence, and health. Employing an instrumental variables approach, we find that robot adoption negatively affects medium-educated workers’ well-being, particularly its eudaimonic dimension, supporting the decreasing agency thesis. In contrast, low- and highly educated workers experience positive effects. These impacts are more pronounced among women and weaker in countries with robust compensatory social policies.

WP442. Why the Happiest Moments in Life are Sometimes Short? The Role of Psychological Traits and Socio-Economic Circumstances

This paper studies happiness’ variability in the course of life and examines how psychological and socio-economic factors influence the probability that an individual is capable of identifying the happiest period in life and its length. The study is based on SHARELIFE data and uses logistic regression and Cox proportional hazards models. Results show that the personality traits significantly, but differently, influence the probability of isolating the happiest life period and its length. Importantly, both positive and negative socio-economic circumstances augment the probability of identifying the happiest period and shorten its duration. These circumstances relate to familial events and socioeconomic status in the life course. The happiest moments of life are thus concentrated around not only positive but also negative changes in life. Our results contribute to the research on changes in the levels of happiness by identifying factors shaping occurrence and duration of the most happiest moments in life.

WP411. Inequality and happiness: the role of income versus wealth inequality

There are conflicting theories about whether individuals like or dislike inequality, or in other words, whether living in an unequal country increases or decreases their subjective well-being. The empirical literature has also not yet reached a consensus. In this paper, we add a new perspective to the inequality-happiness puzzle. First, we study not only income inequality, but also wealth inequality, which has so far been overlooked in the happiness literature. Second, we reach beyond the usually studied Gini coefficient and top income shares, looking also at the other parts of income or wealth distribution. Using data from the integrated World Values Surveys and European Values Surveys for over 50 countries, matched with World Inequality Database data over the years 1981-2020, we find that individuals are happier with increases in the top 10% and top 1% shares of wealth and less happy with increases in the middle 40% share of either wealth or pre-tax income. Increasing the bottom 50% share of after-tax income also makes individuals happier, suggesting that they favor income redistribution. We offer possible explanations for these findings.

WP343. Predicting well-being based on features visible from space – the case of Warsaw

In recent years, availability of satellite imagery has grown rapidly. In addition, deep neural networks gained popularity and become widely used in various applications. This article focuses on using innovative deep learning and machine learning methods with combination of data that is describing objects visible from space. High resolution daytime satellite images are used to extract features for particular areas with the use of transfer learning and convolutional neural networks. Then extracted features are used in machine learning models (LASSO and random forest) as predictors of various socio-economic indicators. The analysis is performed on a local level of Warsaw districts. The findings from such approach can be a great help to get almost continuous measurement of the economic well-being, independently of statistical offices.

WP274. Top incomes and subjective well-being

We use data from the World Wealth & Income Database, the European Values Surveys and World Values Surveys to estimate the relationship between top income shares and subjective well-being in a sample of 35 countries observed between 1980s and 2010s (139 surveys and more than 200,000 respondents). Results show that top 1% income shares are positively associated with happiness, but not with life satisfaction. The effect is present in a subsample of Western countries. We discuss possible explanations for the positive association between top income shares and happiness.

WP36. Impact Of Social Capital On Individual Well-Being In Poland - Proxy-Based Approach

In this paper we attempt to quantify the impact of social capital on individual well-being. We follow the Putnam (1995) approach and select five key social capital components to construct a synthetic index for social capital using a multivariate probit model. Social capital is considered as one of the three crucial individual endowments: physical capital, human capital and social capital. The impact of the synthetically constructed social capital index on individual's well-being is estimated using a Mincer type earning equation. The results show that social capital explains up to 20% of income variation both at individual and household level. However, human capital and physical capital remain the critical determinants of individual income.
