Dividing the Pie
首次利用企业层面面板数据研究劳动收入份额的决定因素，发现2001-2010年间信息技术使用增加是降低劳动份额的主因，而瑞士份额稳定源于技术进步缓慢和行业再分配。
The authors are the first to study the factors determining labor’s share of income on the level of the individual firm, employing an unusually informative panel data set. The empirical examination is concerned with Switzerland, which stands out as one of the very few developed countries with a stable labor share. Broadly confirming results from previous cross-country and industry-level studies, the authors find that the main factor decreasing the labor share between 2001 and 2010 was the increase in the firm’s share of workers using information and communication technology. The main reasons why Switzerland’s labor share remained almost constant are the counteracting effects of a relatively slow rate of technological progress in 1980 to 1995 and sectoral reallocation toward industries with above-average labor shares.
