Welcome to a new episode of the Worldonomics Podcast! In this episode, we dive into a critical discussion I were joined by Mark Wallace, founder of the Brisbane-based economics consulting firm Econisis. Mark shares his invaluable insights on how social infrastructure, from housing to public services, shapes local communities and how tackling homelessness requires a strategic balance of economic policy and social investment. We also learn how economists use data to make informed policy decisions, and how insignificant inflation is to investing in social infrastructure.  Tune in to learn how economics is applied in practice and the long-term benefits of building resilient, inclusive cities.
