Why do people give? What does generosity really mean, and what shapes charitable behavior in Slovakia compared to other countries? To explore these questions, we speak with experimental and behavioral economist Matej Lorko. We discuss what behavioral economics reveals about human decision-making, how economists study altruism in laboratory settings, and whether charitable giving is driven more by empathy, moral values, or subtle forms of self-interest. We also examine how experimental research can inform public policy, support the nonprofit sector, and deepen our understanding of cooperation, trust, and prosocial behavior in modern societies. The new episode of Slovak Sound Check explores grammatical gender and polite forms of address in Slovak.
