Wellcome to 21st investors.

As Niall Ferguson wrote in The Ascent of Money: A Financial History of the World, throughout the history of Western civilization, there has been a recurrent hostility to finance and financiers, rooted in the idea that those who make their living from lending money are somehow parasitical on the 'real' economic activities of agriculture and manufacturing. This hostility has three causes. It is partly because debtors have tended to outnumber creditors and the former have seldom felt very well disposed towards the latter. It is partly because financial crises and scandals occur frequently enough to make finance appear to be a cause of poverty rather than prosperity, volatility rather than stability. And it is partly because, for centuries, financial services in countries all over the world were disproportionately provided by members of ethnic or religious minorities, who had been excluded from land ownership or public office but enjoyed success in finance because of their own tight-knit networks of kinship and trust.

 Despite our deeply rooted prejudices against 'filthy lucre', however, money is the root of most progress. To adapt a phrase from Jacob Bronowski (whose marvellous television history of scientific progress I watched avidly as a schoolboy), the ascent of money has been essential to the ascent of man. Far from being the work of mere leeches intent on sucking the life's blood out of indebted families or gambling with the savings of widows and orphans, financial innovation has been an indispensable factor in man's advance from wretched subsistence to the giddy heights of material prosperity that so many people know today. The evolution of credit and debt was as important as any technological innovation in the rise of civilization, from ancient Babylon to present-day Hong Kong. Banks and the bond market provided the material basis for the splendours of the Italian Renaissance. Corporate finance was the indispensable foundation of both the Dutch and British empires, just as the triumph of the United States in the twentieth century was inseparable from advances in insurance, mortgage finance and consumer credit. 

In 1947 the total value added by the financial sector to US gross domestic product was 2.3 per cent; by 2005 its contribution had risen to 7.7 per cent of GDP. In other words, approximately $1 of every $ 1 3 paid to employees in the United States now goes to people working in finance.5 Finance is even more important in Britain, where it accounted for 9.4 per cent of GDP in 2006. The financial sector has also become the most powerful magnet in the world for academic talent. Back in 1970 only around 5 per cent of the men graduating from Harvard, where I teach, went into finance. By 1990 that figure had risen to 15 per cent. Last year the proportion was even higher. According to the Harvard Crimson, more than 20 per cent of the men in the Class of 2007, and 10 per cent of the women, expected their first jobs to be at banks. And who could blame them? In recent years, the pay packages in finance have been nearly three times the salaries earned by Ivy League graduates in other sectors of the economy.

Whether they put their money into commodities, works of art, vintage wine or exotic asset-backed securities, investors made money.

How were these wonders to be explained? According to one school of thought, the latest financial innovations had brought about a fundamental improvement in the efficiency of the global capital market, allowing risk to be allocated to those best able to bear it.

So here we are to look for the ways to put our money as 21st century investors and, with the latest financial innovations, make money.

Thak you all.
