When Markets Go Mad

In the last of this three-part series on modern finance, Evan Davis looks at the roots of the current crisis: the bubble in property prices and the effect it had on the global financial markets and the people operating within them. The markets lie at the heart of the capitalist system. Every second of every day they set prices that determine how much we pay for our food, and the cost of a foreign holiday. But what are they? Who is running them? And why do the prices run wild so often? Evan Davis reveals some uncomfortable truths about what is really driving our economic system.
