When technological change occurs, it increases the productivity of factors of production such as labor and capital. This increase could be proportionate across all the factors, or the productivity of one factor might increase by an especially large multiple. In the technical language of economics, technical change could be 'factor neutral' or it could be biased toward one factor.The PIs use firm-level panel data to directly assess whether technological change is biased towards labor or is factor neutral. This is important because other economists working in industrial economics, productivity, and economic growth have made different assumptions about the effects of technological change. This study provides empirical evidence for these assumptions.The research team also analyzes their data to determine how firm R&D activities affect the speed and direction of technological change in specific firms. The result is a more precise measure of the relationship between R&D activities and productivity growth.The bias of technological change influences how goods and services are produced and shapes the evolution of individual workplaces, firms, and entire industries. This project is a step towards understanding the sources of technological progress and the resulting societal impact.

当技术变革发生时，它会提高生产因素（例如劳动力和资本）的生产率。 在所有因素中，这种增加可能是比例的，或者一个因素的生产力可能会增加一个特别大的倍数。 在经济学的技术语言中，技术变革可能是“中立因素”，也可能偏向一个因素。PIS使用公司级的面板数据直接评估技术变革是否偏向劳动或因素中立。 这很重要，因为其他从事工业经济学，生产力和经济增长的经济学家对技术变革的影响做出了不同的假设。 这项研究为这些假设提供了经验证据。研究团队还分析了他们的数据，以确定公司的研发活动如何影响特定公司技术变革的速度和方向。 结果是对研发活动与生产率增长之间关系的更精确度量。技术变革的偏见影响了商品和服务的生产方式，并塑造了单个工作场所，公司和整个行业的演变。 该项目是了解技术进步的来源和由此产生的社会影响的一步。
