Coordinating intergenerational redistribution and the repayment of public debt: an experimental test of Tabellini (1991)
通过实验室实验检验Tabellini（1991）模型，发现老年一代通过协调债券投资来分化年轻一代，从而确保债务偿还获得多数支持，揭示了协调在财富不平等与公共债务关系中的关键作用。
Abstract Is there a link between public debt and wealth inequality? Could government bondholders use intra-generational redistribution strategically to make the repayment of debt politically viable? We reconsider the model of Tabellini (J Polit Econ 99:335–357, 1991) and expose the role of coordination and divide-and-conquer . By coordinating their bond investments, the old generation splits up the young generation and secures a majority favoring debt repayment. Coordination therefore mediates the impact of wealth inequality on public debt. We test the model in a laboratory experiment and find that subjects often coordinate to exploit the link between inter- and intragenerational redistribution. Hence, coordination plays an important role in the strategic creation and exploitation of minorities, and thus in the accumulation of public debt.
