Time and Work in Eighteenth-Century London
利用证人证言重建1750-1800年间伦敦工人的年度劳动时间，发现18世纪中叶至末期工作时间快速变化，这对理解工业革命期间的全要素生产率有重要影响。
Witnesses' accounts are used to analyze changes in working hours between 1750 and 1800. Two findings stand out. The article demonstrates that the information contained in witnesses' accounts allows us to reconstruct historical time-budgets and provides extensive tests of the new method. Estimates of annual labor input in 1749/63 and 1799/1803 are presented. It emerges that the number of annual working hours changed rapidly between the middle and the of the eighteenth century. These findings have important implications for the issue of total factor productivity during the Industrial Revolution.
