Using a one-sector, discrete-time Ramsey model, we analyze and compare the implications for welfare, capital accumulation, and speed of convergence to the steady state of two classes of utility functions that represent Gorman preferences, namely homothetic and Stone–Geary preferences. For identical economies, we show that the preference structure does not affect only the capital dynamics and social welfare but also the speed of convergence to the steady-state equilibrium.

两类戈尔曼偏好下的拉姆齐模型中的福利和收敛速度

使用单部门离散时间拉姆西模型，我们分析并比较了福利，资本积累和收敛速度对代表戈尔曼偏好的两类效用函数（即同质偏好和斯通-盖瑞偏好）的稳态的影响。 。对于相同的经济体，我们证明了偏好结构不仅会影响资本动态和社会福利，而且会影响收敛到稳态均衡的速度。
