Conventional models of the politics of economic reform tend to be based on an assumption about the costs and benefits of reform, known informally as the J-curve. Reforms are expected to make things worse before they get better. This presents a classictime inconsistency dilemmafor reformist governments forced to demand severe sacrifices from the public in the short term for the mere promise of future gains. In response, political economy models of the reform process have tended to stress the importance of insulating governments from the pressures of the short-term losers until a sufficient constituency of winners has been created with a stake in supporting and enhancing the reforms.
