Katie,
Fortunately, the file drawer problem is unlikely to threaten the validity of your results. For more information on this, please see the following article in press at Personnel Psychology (available online at http://mypage.iu.edu/~haguinis/pubs.html):
Dalton, D. R., Aguinis, H., Dalton, C. A., Bosco, F. A., & Pierce, C. A. (in press). Revisiting the file drawer problem in meta-analysis: An empirical assessment of published and non-published correlation matrices. Personnel Psychology.
Abstract
The file drawer problem rests on the assumption that statistically non-significant results are less likely to be published in primary-level studies and less likely to be included in meta-analytic reviews, thereby resulting in upwardly biased meta-analytically derived effect sizes. We conducted five studies to assess the extent of the file drawer problem in non-experimental research. In Study 1, we examined 37,970 correlations included in 403 matrices published in Academy of Management Journal (AMJ), Journal of Applied Psychology (JAP), and Personnel Psychology (PPsych) between 1985 and 2009 and found that 46.81% of those correlations are not statistically significant. In Study 2, we examined 6,935 correlations used as input in 51 meta-analyses published in AMJ, JAP, PPsych, and elsewhere between 1982 and 2009 and found that 44.31% of those correlations are not statistically significant. In Study 3, we examined 13,943 correlations reported in 167 matrices in non-published manuscripts and found that 45.45% of those correlations are not statistically significant. In Study 4, we examined 20,860 correlations reported in 217 matrices in doctoral dissertations and found that 50.78% of those correlations are not statistically significant. In Study 5, we compared the average magnitude of a sample of 1,002 correlations from Study 1 (published articles) versus 1,224 from Study 4 (dissertations) and found that they were virtually identical (i.e., .2270 and .2279, respectively). In sum, our five studies provide consistent empirical evidence that the file drawer problem does not produce an inflation bias and does not pose a serious threat to the validity of meta-analytically derived conclusions as is currently believed.
All the best,
--Herman.

Subject: [OB-LIST] Invitation for unpublished studies on alliance diversity and firm performance
*** Apologies for cross-postings ***
Dear colleagues,
We are collecting unpublished studies for our meta-analysis on alliance diversity and firm performance. To address the file-drawer problem (Rosenthal, 1979), we would like to request for a notification of any working papers or unpublished studies that take into account the empirical effect of alliance diversity on firm performance. We are including analyses of multiparty alliance as well as alliance portfolios in this study and are hoping to examine the many facets of alliance diversity. Some examples of alliance diversity might include partner diversity, governance diversity, industry diversity, national diversity, and organizational diversity (Jiang, Tao, & Santoro, 2010). Our definition of firm performance incorporates accounting measures including but not limited to ROA, ROI, EPS, debt ratios, and market-based performance measures such as the change of stock prices and Tobin's Q.
We are also interested in variables that would potentially moderate the relationship between alliance diversity and firm performance, such as firm size, firm age, alliance size, financial position, and ownership level. It would be our gain if you could notify us of any study that includes these variables with regard to alliance diversity and firm performance.
Again, we would greatly appreciate your notice if you believe that your study (or other studies that you know of), whether it be a working paper or an unpublished study, could help us in identifying the empirical effects of alliance diversity and firm performance.
Thank you in advance and sincerely,
Katie Kirkpatrick
