本文研究了三个无限时域、代表性代理内生增长模型中的最优税收问题。第一个模型是一个凸模型，其中物质资本和人力资本是完全对称的。我们的第二个模型通过卢卡斯式的技术结合了弹性劳动力供应。对这两个模型的分析指出了假设政府支出是外生的危险。在我们的第三个模型中，我们将政府支出作为资本形成的生产性投入，表明资本的限制税率不再为零。在数值模拟中，我们发现在所有三个模型中对增长和福利的影响相似。
We study the problem of optimal taxation in three infinite-horizon, representative-agent endogenous growth models. The first model is a convex model in which physical and human capital are perfectly symmetric. Our second model incorporates elastic labor supply through a Lucas-style technology. Analysis of these two models points out the danger of assuming that government expenditures are exogenous. In our third model, we include government expenditures as a productive input in capital formation, showing that the limiting tax rate on capital is no longer zero. In numerical simulations, we find similar effects on growth and welfare in all three models.
