Firm size, age and efficiency: Evidence from Kenyan manufacturing firms
利用235家肯尼亚食品、木材、纺织和金属行业企业的面板数据，估计随机前沿生产函数，发现企业规模对木材和纺织行业的技术效率有显著正向影响，而企业年龄仅在纺织行业显著。
Translog stochastic frontier production functions are estimated using an unbalanced panel of 235 Kenyan manufacturing firms in the food, wood, textile and metal sectors. The sectors are estimated individually in order to investigate whether technical efficiency is systematically related to the size and age of firms. The evidence suggests that firm size has a positive and significant effect in the wood and textile sectors. The age effect is less systematic, but is insignificant in all sectors, except textiles.
