is misleading.

The Book

The Ledger

Why the World's Most Important Number is Wrong, and What We Should Measure Instead

Structured as a play in five Acts, The Ledger moves from the failure of GDP, to the assets we ignore, to the warning signals we miss, to the reckoning, and finally, the solution. A pragmatic blueprint for governments, investors, and citizens who suspect that the official numbers no longer match reality.

Book Reviews

Punchy, articulate insight into the heart of global finance. Extraordinary read.

This book reveals incredible insight (and shone a spotlight) about the key gaps in how we understand finance. The author — a leading financier — has developed a very convincing argument that has global impact. He takes you step by step through areas of National accounting. None of his argument is complex but the implications are huge! Governments, bankers (financial actors) totally misrepresent and distort our views about the global economy. This is a brilliant read about a subject that could not be more important.

Fantastic examples which make the book impossible to put down!

Great read! The book explains how GDP growth alone does not guarantee equal prosperity, making complex economic ideas surprisingly accessible. Fantastic examples, which makes the book very interesting and hard to put down. Overall, it is an insightful read for anyone interested in today's world, economics and how GDP shapes society.

Mindset shift that could break the downward policy making spiral in so many countries

Simple but powerful concepts — net book value matters more than EBITDA (or even EBBS — earnings before bad stuff). If only policy makers in democracies could get within a country mile of these concepts, government and governance would improve by 10X. Thanks for spelling this all out so clearly.
