|June 2019||From Theory to Practice: Field Experimental Evidence on Early Exposure of Engineering Majors to Professional Work|
with Matt Marx: w26013
Young workers typically enter the professional labor market only after completing higher education. We investigate how earlier professional work experience affects skilled worker development. In a field experiment, 1,787 Engineering majors were randomly assigned to 6-month work terms to begin either in the second or third year of studies. Early exposure caused systematic differences in inclination to take Engineering elective courses, choice of major, and the probability of persisting in Engineering years later—consistent with engagement, retention, and sorting effects. Early exposure notably increased academic and professional outcomes of lower-income students.
|April 2018||Amateurs Crowds & Professional Entrepreneurs as Platform Complementors|
Platforms often have “crowds” of amateurs working on them as complementors, in other cases professional entrepreneurs—or both. What can a platform owner do to implement these outcomes? I document evidence on mobile app developers showing that just small, incremental changes in platform design—related to the bare minimum costs required to build an app and factors affecting non-pecuniary payoffs—can lead the “bottom-to-fall-out” of the market to amateurs. Where the bottom-falls-out, there is a flood of lowest-quality developers who nonetheless are long-lived on the platform and engage in relatively high development activity. I find no evidence that amateurs crowd-out development activity of top developers in this context. Moreover, the bottom-falling-out is associated with the generation of ...
|June 2015||Innovation Experiments: Researching Technical Advance, Knowledge Production, and the Design of Supporting Institutions|
with Karim R. Lakhani
in Innovation Policy and the Economy, Volume 16, Josh Lerner and Scott Stern, editors
This paper discusses several challenges in designing field experiments to better understand how organizational and institutional design shapes innovation outcomes and the production of knowledge. We proceed to describe the field experimental research program carried out by our Crowd Innovation Laboratory at Harvard University to clarify how we have attempted to address these research design challenges. This program has simultaneously solved important practical innovation problems for partner organizations, like NASA and Harvard Medical School, while contributing research advances, particularly in relation to innovation contests and tournaments.
