18. Proprietary data also include data that the researcher had to purchase from a commercial
data vendor and administrative data.
19. There are also occasional data dumps where firms give out data to researchers
because they know one of the researchers personally or through contacts (Cohen
and Einav, 2007 is one such example). Access in this case is fast and easy but the
one-shot nature of the relationship prevents any follow-up or additional data extraction
based on initial results and is not free of legal risk about data disclosure.
20. One of us was involved in a NDA that required her research institution to accept
responsibility for any accident or death caused by her presence on the firm’s
premises.
21. Interestingly several funding agencies are moving towards demanding that the data
collected as part of funded projects be publicly available, in sharp contrast with the
funding needs for the type of research described in this section.
22. In an analysis of articles published in three leading economics journals (American
Economic Review, Journal of Political Economy, Quarterly Journal of Economics),
Hamermesh (2013) noted a steady increase in the number of coauthors over time
with the first four-author paper published in 1993 and the first five-author and sixauthor
papers published in 2011. Currently, there is very little penalty for publishing
coauthored papers in economics.
