A Short-Run View of What Computers Do: Evidence from a UK Tax Incentive
利用英国ICT投资税收减免的自然实验，研究发现ICT短期内主要补充非常规认知密集型工作，并导致企业内部不平等加剧，任务模型最能解释观察到的模式。
We study the short-run causal effect of Information and Communication Technology (ICT) adoption on employment and wage distribution. We exploit a natural experiment generated by a tax allowance on ICT investments and find that the primary effect of ICT is to complement nonroutine, cognitive-intensive work. We also find that the ICT investments led to organizational changes that were associated with increased inequality within the firm and we discuss our findings in the context of theories of ICT adoption and wage inequality. We find that tasks-based models of technological change best fit the patterns that we observe.
