Over the past 25 years, Madrid has quietly carried out a free-market transformation. While much of Europe moved toward expanding regulation and growing state control, Spain's capital region chose a different path-lowering taxes, cutting red tape, opening markets, and partnering with the private sector to improve public services.

Today, Madrid's economy, roughly the size of Portugal's, stands as one of Europe's most dynamic regional success stories. The results are measurable: faster growth than the national average, stronger job creation, rising incomes, and increased foreign investment.

But Madrid's story is not only about economic policy. Nearly half of its residents were born in another Spanish region or abroad. Rather than relying on identity-based politics, Madrid has fostered integration through opportunity and equal treatment under the law.

In The Madrid Model: How Freedom and Openness Created an Economic Powerhouse, author Diego Sánchez de la Cruz combines rigorous policy analysis with a broader reflection on the principles of economic freedom, federalism, and democratic legitimacy. He offers both a theoretical argument for liberal institutions and a real-world case study of how decentralization and limited government can deliver prosperity while strengthening social cohesion.
