Does earning money empower women? Evidence from India

This study investigates the relationship between women’s earnings and empowerment in India, focusing on married women aged 15-49. Utilizing data from the Indian DHS (2019–21), the research employs Bayesian statistical analyses to explore how earning money influences women’s empowerment in areas like financial and bodily autonomy, marital rights, attitudes towards intimate partner violence, and peer recognition. The study reveals that while earning money enhances women’s financial and bodily autonomy, decision-making capacity, and societal recognition, it simultaneously restricts their marital rights, degrades intimate partner relations, and increases the risk of domestic violence. The findings contribute to the discourse on gender equality, offering empirical insights into the complexities of women’s empowerment in India. This research has practical implications for policymakers, NGOs, and stakeholders working towards women’s empowerment, providing a deeper understanding of the varied impact of women’s economic contributions in India’s socio-cultural context.

Why and when entrepreneurs with calling perform better? The effects of calling and money motivation on entrepreneurial performance

Although calling is frequently stated in entrepreneurial practice, empirical study examining the impact of calling on entrepreneurial activities is scarce. Based on self-regulation theory, two-wave survey is administered among 174 Chinese entrepreneurs to investigate the influence of calling on entrepreneurial performance. The results indicate that calling has a significant and positive impact on entrepreneurial performance of entrepreneurs. Innovative behavior mediates the positive association between calling and entrepreneurial performance. Money motivation negatively moderates the indirect effect of calling on entrepreneurial performance via innovative behavior. Precisely, the positive effect of calling on entrepreneurial performance via innovative behavior is stronger at low level of money motivation. This study theoretically enriches the understanding of factors driving entrepreneurial performance and extends the application of calling to the entrepreneurial field.

Karma economies for sustainable urban mobility – a fair approach to public good value pricing

City road infrastructure can be considered a public good, and congestion is the intersection of demand for mobility with the limited available transportation supply. Congestion pricing is effective in reducing demand to sustainable levels below network capacity limits, but also controversial, as it introduces equity issues and systematically discriminates against lower-income groups. Karma is a non-monetary, fair, and efficient resource allocation mechanism that employs an artificial currency different from money, incentivises cooperation amongst selfish individuals, and achieves a balance between giving and taking. Where money does not do its job, Karma achieves socially more desirable allocations by being aligned with consumers’ needs rather than their financial power. This work highlights the value proposition of Karma, provides guidance on Karma mechanism design, and equips the reader with a useful software framework to model Karma economies and predict consumers’ behaviour. A case study of road pricing demonstrates Karma’s potential.

Currency harmonisation in the Southern African Development Community: a pathway to addressing the PPP puzzle

Over a century since its inception, the purchasing power parity (PPP) theory, linking exchange rates to relative prices, remains one of the most widely accepted and influential theories in international economics. Despite its theoretical appeal, the empirical validity of PPP remains highly contentious. This study examines the empirical support for PPP within the Southern African Development Community (SADC) region. We employ a battery of linear and ESTAR nonlinear unit root tests, panel stationarity tests, and multivariate cointegration analysis on two distinct numéraire currencies—US dollar and the South African rand (ZAR)—alongside consumer price index (CPI) data for 14 SADC countries over the monthly period 1990:01–2022:04. To this end, we test two important hypotheses in the literature on whether the empirical validity of PPP is influenced by the: (i) ‘numéraire currency’ effect, and (ii) ‘border’ effect. Overall, our findings lend overwhelming support to both of these conjectures. Further evidence suggests that the half-life of parity reversion is significantly shorter for the ZAR-based real exchange rates. These findings imply that SADC meets the optimum currency area (OCA) requirements, making the proposed monetary union a promising prospect.

Close relationship partners of impartial altruists do not report diminished relationship quality and are similarly altruistic

Impartial altruism is often considered a moral ideal but is rare in practice. Instead, generosity typically decreases as social distance increases, a phenomenon termed social discounting. Most people prefer this partiality in their close relationships and view impartial altruists as poorer relationship partners. This suggests real-world impartial altruism may be rare because it reduces—or is perceived to reduce—the quality of close relationships. To investigate this, we compared patterns of generosity and social relationship quality in a rare sample of individuals who had engaged in extraordinary real-world impartial altruism (altruistic kidney donors; n = 59) and their closest friend or family member (n = 59) to controls (n = 71) and their closest others (n = 71). We designed a direct test of third-party social discounting, which experimentally confirmed real-world altruists’ impartiality, finding that they are more likely than controls to split resources evenly between close and distant others rather than favoring close others. However, we found no statistically significant association between impartial altruism and social relationship quality. Instead, we found that altruists’ close others also show more impartiality than controls. This suggests value homophily (shared moral values) among altruists, which may represent a protective factor for close relationships in the context of impartial altruism.
