This paper investigates public attitudes towards education spending based on a survey experiment. It enquires whether a trade-off between education and other welfare domains, namely healthcare, unemployment benefits and pensions, diminishes support for higher public spending on education. Drawing on five Organisation for Economic Co-operation and Development (OECD) countries (Italy, Spain, Greece, Mexico and Turkey), the paper demonstrates that education spending preferences are contingent on the nature of trade-offs and the priorities of the stakeholder groups. Testing the predictive power of age, income, ideology, labour market positioning and gender, our research finds robust support for public spending on education across all countries. Nonetheless, this support diminishes significantly when trade-offs that are linked to cuts in other welfare domains are introduced.
