Directed Technical Change in Labor and Environmental Economics
综述了定向技术变革在环境与劳动经济学中的研究，指出两个领域在理论和实证上的共性，并强调平衡增长路径缺失与绿色技术发展缓慢、劳动收入不平等加剧的关联。
It is increasingly evident that the direction of technological change responds to economic incentives. We review the literature on directed technical change in the context of environmental economics and labor economics, and we show that these fields have much in common both theoretically and empirically. We emphasize the importance of a balanced growth path and show that the lack of such a path is closely related to the slow development of green technologies in environmental economics and to growing inequality in labor economics. We discuss whether the direction of innovation is efficient.
