Workers who sort into institutional settings they prefer may work twice (or many more times) as hard in these preferred settings. This productivity effect is especially important in institutional settings where a taste for competition is strongest.

Interpersonal effects of physical space indirectly affect performance for group engaged in knowledge work. Physical space shapes performance indirectly by affecting group members' arousal and territorial behaviour, which together influence information elaboration. The physical context in which a group works can shape interpersonal dynamics and ultimately group performance.

Bakhshi, H., Edwards, J., Roper, S., Scully, J., Shaw, D., Morley, L., Rathbone, N.

A voucher programme for SMEs in Manchester, UK, to invest in creative projects showed significant positive, but short-term, effects on innovation and sales growth.

Paravisini, D. & Schoar, A.

This experiment provides direct evidence on how information technologies can lead to the decentralisation of decision-making processes within organisations, and how IT solutions may represent an effective and low-cost alternative to steepening or increasing monetary incentives. Providing credit scores increased the effort committees put into solving more difficult problems, increased committees' overall output, and reduced the need for higher-level manager involvement in the decision-making process.

Boudreau, K., Guinan, E., Lakhani, K., Riedl, C.

This experiment in the context of medical research grants indicates a discount of novelty in research proposals, which may be due to evaluators internalising the average effects of novelty for potential concerns about the lower success rates. However, this censoring of novel projects means that experiments never get a chance to be run and thus the benefits of generating greater diversity of experiments are curtailed. This is of concern to policy makers and society because research funds are being allocated towards more incremental research as compared to high variability and potentially breakthrough efforts.

Does free access to journal articles result in greater diffusion of scientific knowledge? Using a randomized controlled trial of open access publishing, involving 36 participating journals in the sciences, social sciences, and humanities, we report on the effects of free access on article downloads and citations. Articles placed in the open access condition (n=712) received significantly more downloads and reached a broader audience within the first year, yet were cited no more frequently, nor earlier, than subscription-access control articles (n=2533) within 3 yr.

Engle-Warnick, J., Escobal, J., Laszlo, S.

The lack of adoption of new farming technologies despite known benefits is a well-documented phenomenon in development economics. In addition to a number of market constraints, risk aversion predominates the discussion of behavioral determinants of technology adoption. We hypothesize that ambiguity aversion may also be a determinant, since farmers may have less information about the distribution of yield outcomes from new technologies compared with traditional technologies. We test this hypothesis with a laboratory experiment in the field in which we measure risk and ambiguity preferences.

Baer, M., Leenders, R., Oldham, G., Vadera, A.

A laboratory experiment with undergraduate students in a US university explores the effects of intergroup competition and changes in group membership on creativity and collaboration.

Cornet, M., Vroomen, B., van der Steeg, M.

An innovation voucher scheme in the Netherlands appears to successfully encourage SMEs to work with public research institutes on innovative projects.
