Long-Run Implications of Investment-Specific Technological Change
研究投资专用技术变革如何推动美国战后经济增长，通过模型校准发现其贡献超过传统希克斯中性技术进步。
The role that investment-specific technological change played in generating postwar U.S. growth is investigated here. The premise is that the introduction of new, more efficient capital goods is an important source of productivity change, and an attempt is made to disentangle its effects from the more traditional Hicks-neutral form of technological progress. The balanced-growth path for the model is characterized and calibrated to U.S. National Income and Product Account data. The quantitative analysis suggests that investment-specific technological change accounts for the major part of growth.
