First, the Economist Intelligence Unit conducted a survey of 2,300 affluent and wealthy investors with investable assets ranging from £500,000 to in excess of £30 million. Respondents were spread across a number of key international markets, with the highest numbers of respondents from the United States, India, United Kingdom, Singapore, Hong Kong, Canada, Switzerland, Spain, the United Arab Emirates and Monaco. The survey took place between March and April 2008.
This was supplemented with a series of in depth interviews with experts on wealth and behavioural finance. Our thanks are due to the survey respondents and interviewees for their time and insight.
