The World Bank has long been criticized by a range of non-governmental organizations and academics, notably including its former Chief Economist Joseph Stiglitz, who is equally critical of the International Monetary Fund, the US Treasury Department, and US and other developed country trade negotiators. Critics argue that the so-called free market reform policies—which the Bank advocates in many cases—in practice are often harmful to economic development if implemented badly, too quickly ("shock therapy"), in the wrong sequence, or in very weak, uncompetitive economies. World Bank loan agreements can also force procurements of goods and services at uncompetitive, non free-market, prices. Other critical writers such as John Perkins, label the international financial institutions as 'illegal and illegitimate' and a cog of coercive American diplomacy in carrying out financial terrorism.
