Economists and economics have been harshly criticised recently. This book accepts many of the criticisms of conventional theory but argues that the fundamental insights of economics are capable of reinterpretation and reinvention to deal with a host of contemporary concerns – social networks, globalisation, pay inequality, climate change, automation and the growth of 'nudge' policy amongst many others. The author uses his weekly column in the London business newspaper City A.M. to explain new developments in economic thinking and empirical research to a general audience. This book reproduces many of his most provocative columns with accompanying commentary and full references. The author's witty and informed analysis of events provides an ideal introduction to important ideas for anybody interested in how the modern economy works.
