I love these fact-filled micro-documentaries, steeped in history... A masterclass in socioeconomic storytelling (Financial Times on BBC World Service's Fifty Things that Made the Modern Economy)

They are real masterpieces of brevity and audio storytelling . . . brilliant sideways glances . . . I've been surprised by every episode (Monocle Arts Review on BBC World Service's Fifty Things that Made the Modern Economy)

This is what BBC radio is for. The series is utterly compelling and low-key... Just brilliant ideas, told simply. A wonderful, wonderful programme (The Times on BBC World Service's Fifty Things that Made the Modern Economy)

Harford's script is immaculate and so is his presentation (Times of India on BBC World Service's Fifty Things that Made the Modern Economy)

Short chapters are a delight in this frenetic age . . . Best of all, the book is constantly surprising. It brims with innovations I didn't know about, as well as ones I thought I knew about but did not (The Times)

Packed with fascinating detail . . . Harford has an engagingly wry style and his book is a superb introduction to some of the most vital products of human ingenuity (Sunday Times)

Harford's richness of detail bespeaks skill both as an economic analyst and as a popular commentator. His sections on barbed wire, passports, the contraceptive pill, infant formula, the bar code and even that IKEAstaple, the Billy bookcase, are well researched, racily written and genuinely thought-provoking. His five page essay on the pill is infinitely subtler (and more feminist) than the usual stuff about empowerment . . . This is an entertaining book that might distract you from your gramophone for more than an evening and will find a secure place beside Harford's other books on your Billy bookcase.

Who thought up paper money? How did the contraceptive pill change the face of the legal profession? Why was the horse collar as important for human progress as the steam engine? How did the humble spreadsheet turn the world of finance upside-down?

The world economy defies comprehension. A continuously-changing system of immense complexity, it offers over ten billion distinct products and services, doubles in size every fifteen years, and links almost every one of the planet's seven billion people. It delivers astonishing luxury to hundreds of millions. It also leaves hundreds of millions behind, puts tremendous strains on the ecosystem, and has an alarming habit of stalling. Nobody is in charge of it. Indeed, no individual understands more than a fraction of what's going on.
How can we make sense of this bewildering system on which our lives depend?

From the tally-stick to Bitcoin, the canal lock to the jumbo jet, each invention in Tim Harford's fascinating new book has its own curious, surprising and memorable story, a vignette against a grand backdrop. Step by step, readers will start to understand where we are, how we got here, and where we might be going next.

Hidden connections will be laid bare: how the barcode undermined family corner shops; why the gramophone widened inequality; how barbed wire shaped America. We'll meet the characters who developed some of these inventions, profited from them, or were ruined by them. We'll trace the economic principles that help to explain their transformative effects. And we'll ask what lessons we can learn to make wise use of future inventions, in a world where the pace of innovation will only accelerate.
