Abstract
This study seeks, first, to experimentally measure the effect of apprentice labor inputs on firm output. Second, the study seeks to understand the mechanisms behind and timing of any effect, using random variation in the match between apprentice and firm, and repeated data on training inputs, apprentice progress, and firm output during the training period.

Experimental Design
Experimental Design
Apprentices were asked to state firms with which they would like to train from a set of recruited firms based on geographic feasibility and interest; they were then randomized into one of those firms
Experimental Design Details

Randomization was done in office by a computer
Randomization Unit
Individual
Was the treatment clustered?
No
