Mariana Mazzucato

To understand Mariana Mazzucato, you have to begin with a reframing: who actually creates value in an economy — the private sector alone, or a broader system that includes the state?

In dominant economic narratives, governments are often portrayed as reactive — correcting market failures, regulating excesses, or redistributing wealth after it has been created by private enterprise.

Mazzucato challenges that assumption.

At the center of her worldview is a defining claim:

Drawing on historical and contemporary examples, Mazzucato argues that many of the most transformative innovations — such as the internet, GPS, and foundational pharmaceutical research — were made possible by public investment. Governments took on high-risk, long-term projects that private firms were unwilling or unable to pursue.

From this perspective, innovation is collective.

It emerges from an ecosystem of public institutions, private firms, and social investments. The state often plays a catalytic role — funding early-stage research, setting missions, and creating the conditions for new industries to emerge.

This leads to a broader argument about value.

Mazzucato critiques the tendency to equate market price with value creation. She distinguishes between value creation and value extraction, arguing that some actors contribute to building new capabilities, while others primarily capture existing value through financialization or rent-seeking.

Her work calls for a more deliberate approach to economic direction.

Rather than leaving innovation to market forces alone, she advocates for mission-oriented policy — public efforts to address large-scale challenges such as climate change, health, and inequality by coordinating investment and aligning incentives across sectors.

Supporters see Mazzucato as a leading voice in rethinking the role of government.

They argue that she provides a more accurate account of how innovation actually occurs and offers a framework for addressing complex societal challenges through coordinated action. Her work has influenced policy discussions around industrial strategy, public investment, and innovation ecosystems.

From this perspective, Mazzucato expands the analysis of economic systems to include the state as an active participant in shaping markets and directing long-term development.

Critics, however, raise important concerns.

They argue that expanding the role of the state risks inefficiency, political bias, or misallocation of resources. Governments may lack the information or incentives to effectively direct innovation, and public investments can be influenced by short-term political considerations.

Critics also question how to ensure accountability — if the state takes on a larger role in creating value, how are the returns distributed and who benefits?

A deeper tension lies in the relationship between direction and discovery.

How can governments set ambitious goals without stifling entrepreneurial experimentation? And how can public investment be structured to both enable innovation and ensure that its benefits are broadly shared?
