This volume is a collection of essays honoring Carlo Casarosa, presented at the "Giornata di studi in onore di Carlo Casarosa" held at the department of economics and management at the University of Pisa in 2023. The event gathered colleagues and students for a strictly scientific meeting. The essays span five broad themes: classical economics, public finance, labor market, market functioning, and consumption and saving, reflecting Casarosa's contributions to microeconomic and macroeconomic thought. The volume also includes the bibliography of Casarosa's scientific work.
