We estimate productivity gains and employment effects of ultrafast broadband (UFB) adoption and test whether effects differ when firms undertake complementary organizational investments. Using an IV strategy based on proximity to schools (that were targeted in the UFB roll-out), we find that UFB adoption has a positive impact on multifactor productivity (MFP) over a four year horizon and a negative impact on employment (potentially due to increased outsourcing). The positive MFP effects are most clearly observed in firms that also make complementary investments to gain the most benefit from their UFB. The negative employment effects are observed especially in firms with initial low computer intensity.

我们估计了采用超高速宽带 (UFB) 的生产力提高和就业影响，并测试了当公司进行互补的组织投资时，影响是否不同。使用基于靠近学校的 IV 策略（这是 UFB 推出的目标），我们发现 UFB 的采用对四年内的多因素生产力 (MFP) 产生积极影响，并对就业产生负面影响（可能是由于以增加外包）。在也进行补充投资以从其 UFB 中获得最大收益的公司中，最明显地观察到积极的 MFP 效应。负面的就业效应在最初计算机强度较低的公司中尤为明显。
