===Lerner et al 2011===
Final sample consists of 6398 patents from 472 firms granted from 1984 through may 2007.
 
Buyouts of corporate divisions are most common, followed by private-to-private deals (investments in independent unquoted entities), secondary deals (firms that were already owned by another private equity investor), then public-to-private deals
 
Robustness Checks:
 
*Concern one: Private equity investments for which there was already an existing investor, patents may be double-counted. Employs these patents only the first time they appear then drops them. Results are little changed
*Concern two: Only measures citation count during the 3 years after the award. Using a longer window increases accuracy but decreases sample size. Repeats the analysis through the end of the second calendar year after the patent grant and after the fourth year and finds that results are quantitatively similar.
*Concert three: In divisional buyouts corporate parents may retain best patents and only give low quality patents to the PE backed division. This may lead to an apparent increase in quality in the patents applied for after the award. Addresses this issue by using the longer window for patents above and by rerunning cross tabulations and regressions with divisional buyouts excluded from the sample. Key results are little changed by this shift.

Van de Gucht and Moore find that hazard rate of LBO reversals peaks at about 7 to 8 years after the buyout.
 
Data:

*Restricted to those with stock returns in CRSP in year before LBO, post-LBO status identifiable in Newspaper Abstracts or Ward's Business Directory (1994)

*Full LBO

====Artz et al 2010====
@article{artz_longitudinal_2010,
Hitt et al argue that acquisitions are substitutes for R&D/patents and other investments. We should keep this in mind when using these as regressors in the same equation.

abstract = {The innovative performance of companies has been studied quite extensively and for a long period of time. However, the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators. So far the variety in terms of constructs, measurements, samples, industries and countries has been substantial. This paper studies the innovative performance of a large international sample of nearly 1200 companies in four high-tech industries, using a variety of indicators. These indicators range from R\&D inputs, patent counts and patent citations to new product announcements. The study establishes that a composite construct based on these four indicators clearly catches a latent variable 'innovative performance'. However, our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high-tech industries.

Seeks to establish commonality in the measurement of innovative performance. Its indicators include R&D inputs(expenditures), patent counts, patent citations, and new product announcements. Results of study are that any of these four indicators could be taken as a measure of innovative performance in the broad sense.
