Former World Bank Chief Economist and former Chairman of the U.S. Council of Economic Advisers Joseph E. Stiglitz referred in the late 1990s to a growing consensus that something is wrong with a system having the capacity to impose high costs on a great number of people who are hardly even participants in international financial markets, neither speculating on international investments nor borrowing in foreign currencies. He argued that foreign crises have strong worldwide repercussions due in part to the phenomenon of moral hazard, particularly when many multinational firms deliberately invest in highly risky government bonds in anticipation of a national or international bailout. Although crises can be overcome by emergency financing, employing bailouts places a heavy burden on taxpayers living in the afflicted countries, and the high costs damage standards of living. Stiglitz has advocated finding means of stabilizing short-term international capital flows without adversely affecting long-term foreign direct investment which usually carries new knowledge spillover and technological advancements into economies.
