Benedikt Fecher et al. have published "A Reputation Economy: How Individual Reward Considerations Trump Systemic Arguments for Open Access to Data" in Palgrave Communications.
Here's an excerpt:
In this article, we explore the question of what drives open access to research data using a survey among 1564 mainly German researchers across all disciplines. We show that, regardless of their disciplinary background, researchers recognize the benefits of open access to research data for both their own research and scientific progress as a whole. Nonetheless, most researchers share their data only selectively. We show that individual reward considerations conflict with widespread data sharing. Based on our results, we present policy implications that are in line with both individual reward considerations and scientific progress.
