本文提供了一些新的估计的贡献，学习的劳动生产率的快速增长观察到的自由船在第二次世界大战期间的建设。这项研究利用了国家档案馆保存的当代记录中关于实物资本投资和船舶质量的新数据。学习率的估计被证明是敏感的列入新的资本数据，和船舶质量的数据提供证据表明，部分测量的生产力提高是以牺牲质量为代价的。
This paper offers some new estimates of the contribution of learning to the rapid increases in labor productivity observed in the construction of Liberty ships during World War II. The study exploits new data on physical capital investment and vessel quality constructed from contemporary records held at the National Archives. Estimates of the rate of learning are shown to be sensitive to the inclusion of the new capital data, and data on vessel quality provide evidence that part of the measured productivity increases were secured at the expense of quality.
