Businesses, firms and markets play an integral part in the development of human civilisation. So how they work, what evidence firms use, and what norms they follow, are of crucial significance for us all. LSE Business Review is a new knowledge-exchange initiative designed to share the best of modern social science ideas, theories and evidence with business decision-makers and professionals, and to learn from them in turn. We present the expertise of professors in finance, economics, business studies, law, management, accounting, social psychology, mathematics, public policy, sociology, geography, philosophy, media, cultural and gender studies, and political science, in accessible and relevant ways for business. And LSE Business Review hosts business professionals and experts with knowledge to give and advice to offer academics. Our focus is topical, tackling the issues of today (and not of yesteryear). And our writing is direct and clear, designed for an audience with much else to get done.
