This document is based on doing business reports prepared under the auspices of the World Bank. Doing Business 2009 is the sixth in a series of annual reports investigating regulations that enhance business activity and those that constrain it. Doing Business presents quantitative indicators on business regulations and the protection of property rights that can be compared across 181 economies, from Afghanistan to Zimbabwe, over time. A set of regulations affecting 10 stages of a business’s life are measured, starting a business, dealing with construction permits, employing workers, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts, and closing a business. Data in Doing Business 2009 are current as of June 1, 2008. The indicators are used to analyze economic outcomes and identify what reforms have worked, where, and why. The Doing Business methodology has limitations. Other areas important to business such as an economy’s proximity to large markets, the quality of its infrastructure services (other than those related to trading across borders), the security of property from theft and looting, the transparency of government procurement, macroeconomic conditions or the underlying strength of institutions, are not studied directly by Doing Business. To make the data comparable across economies, the indicators refer to a specific type of business, generally a local limited liability company operating in the largest business city. Because standard assumptions are used in the data collection, comparisons and benchmarks are valid across economies. The data not only highlight the extent of obstacles to doing business; they also help identify the source of those obstacles, supporting policymakers in designing reform.
