Brazil's stock market, the Bovespa, has gone from approximately 9,000 in September 2002 to over 70,000 in May 2008. Government policies have favored investment (lowering interest rates), retiring foreign debt and expanding growth, and a reformulation of the tax system is being voted in the congress. The British author and researcher Mark Kobayashi-Hillary wrote a book in 2007 titled "Building a Future with BRICs" for European publisher Springer Verlag that examines the growth of the BRICs region and its effect on global sourcing. Contributors to the book include Nandan Nilekani, and Shiv Nadar.
