在静态最优税收模型中，我们检验了诱导性技术变革（ITC）可以显著降低碳税成本的假设。研究和发展部门以节能技术的总存量为代表，在能源生产部门中，这是一种污染资源的弱替代品。使用这个模型，我们分析显示了ITC是如何发生的，并影响了碳税的成本。将ITC规模的定量估计应用于对美国经济进行校准的数值模拟，我们发现现有的经验证据可以将环境税改革的福利成本降低12%。我们对替代参数的测试表明，这一结果对所使用的假设高度敏感，这表明ITC可能导致更大的成本降低。
We examine the hypothesis that induced technological change (ITC) can dramatically lower the cost of a carbon tax in a static optimal tax model. The research and development sector is represented by an aggregate stock of energy-saving technology, which acts as a weak substitute with a polluting resource in the energy generation sector. Using this model, we analytically show how ITC occurs and affects the cost of a carbon tax. Applying quantitative estimates of the size of ITC to numerical simulations calibrated to the US economy, we find that existing empirical evidence can reduce the welfare cost of environmental tax reform by 12%. Our tests of alternative parameters show that this result is highly sensitive to the assumptions used, suggesting that ITC could result in much larger reductions in cost.
