我们研究了免费乘车模型的马尔可夫均衡,其中n个无限活的代理人在私人消费和对持久公共产品的不可逆转贡献之间进行选择。我们证明了当贬值收敛于零时,平衡稳态集收敛于一个唯一点。此外,对于任何贬值水平,随着代理人变得越来越有耐心,最高稳定状态收敛于有效水平。这些结果与可逆投资的情况相反,在可逆投资中,对于任何水平的折旧、贴现因子和人口规模,都存在低效均衡稳定状态的连续体。
We study the Markov equilibria of a model of free riding in which n infinitely lived agents choose between private consumption and irreversible contributions to a durable public good. We show that the set of equilibrium steady states converges to a unique point as depreciation converges to zero. For any level of depreciation, moreover, the highest steady state converges to the efficient level as agents become increasingly patient. These results are in contrast to the case with reversible investments, where a continuum of inefficient equilibrium steady states exists for any level of depreciation, discount factor and size of population.
