This book draws on the analytical framework of New Institutional Economics (NIE) to critically examine the role which law and the legal system play in economic development. Analytical concepts from NIE are used to assess policies which have been supported by multilateral development organisations including securing private property rights, reform of the legal system and financial development. The importance of culture in shaping the legal environment, which in turn influences financial sector development, is also assessed using Oliver Williamson’s ‘levels of social analysis’ framework.
