摘要:Most countries in the developed world face two important fiscal-policy chal- lenges. First, they have large fiscal imbalances, due to a combination of factors including the rapid growth of public debt during the global financial crisis and the pressures put on social insurance systems by population aging. Second, they have experienced growing inequality in the distribution of market incomes, asso- ciated with a variety of factors including changing technology and increasing globalization. A potential solution to both challenges would involve the adop- tion of progressive tax increases, but in the way of such tax increases stands the heightened tax competition also seen in recent years. Thus, new approaches may be needed to achieve a feasible solution to the problems of inequality and fiscal imbalances.
