Some books explain a problem. A few reframe how we understand it entirely.
The Signal Economy: Why Sustainability Is Wired to Fail, and Why Only Structural Change Can Fix It, is one of the latter.
Written by Shaurya Ritwik, one of the most authoritative voices in sustainable finance today, and among the sharpest analysts of how sustainability frameworks perform under the institutional constraints of emerging economies, this book does not traffic in optimism or despair. It offers something rarer: structural clarity.
The diagnosis is precise. Sustainability, as currently architected, has built its own internal economy: one where institutions are rewarded for producing the right signals: disclosures, ratings, pledges, frameworks, regardless of what those signals actually deliver. Capital follows the signal. Governance tracks the signal. Careers are built on the signal. The outcome, meanwhile, goes largely unmeasured and largely unchanged.
This is not a failure of ambition. It is a design outcome.
Grounded in signalling economics and in the structural realities of Asian markets and the Global South, contexts that the dominant sustainability literature has historically marginalised, The Signal Economy introduces original analytical frameworks for diagnosing where sustainability governance breaks down, identifying who bears the structural costs of misalignment, and determining what institutional change would actually move the needle.
For three decades, the sophistication of our frameworks has grown while the physical numbers: emissions, biodiversity loss, climate vulnerability have moved in the wrong direction. The Signal Economy is the first book to name this relationship not as a paradox, but as a predictable consequence of how the system was built.
This is the foundational text in the political economy of sustainable finance.
