Science Is Shaped by Wikipedia: Evidence From a Randomized Control Trial

As the largest encyclopedia in the world, it is not surprising that Wikipedia reflects the state of scientific knowledge. However, Wikipedia is also one of the most accessed websites in the world, including by scientists, which suggests that it also has the potential to shape science. This paper shows that it does. Incorporating ideas into Wikipedia leads to those ideas being used more in the scientific literature.

Does subsidising business advice improve firm performance? Evidence from a large RCT

We evaluate the impact of the UK’s Growth Vouchers Programme, which offered subsidised business advice to 15,207 randomly selected small and medium size enterprises. Using administrative and survey data, we show that the programme increased turnover by 8.2% but only in the short-term and potentially at the expense of non-supported firms. We find that subsidised advice appears to improve firms’ capabilities and practices in a way that is consistent with the increase in turnover.

KAIZEN for Managerial Skills Improvement in Small and Medium Enterprises: An Impact Evaluation Study in a Knitwear Cluster in Vietnam

In the context of knitwear and rolled steel clusters in Vietnam, preliminary short-run impacts of KAIZEN production training reveal positive impacts on entrepreneurs' management knowledge, firms business practices, and willingness-to-pay for the training. Researchers will evaluate the long-run results including a cost-benefit analysis.

High Incentives, Sorting on Skills -- Or just a Taste for Competition? Field Experimental Evidence from an Algorithm Design Contest

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.

The Novelty Paradox & Bias for Normal Science: Evidence from Randomized Medical Grant Proposal Evaluations

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.

Training or Technical Assistance? A Field Experiment to Learn What Works to Increase Managerial Capital for Female Entrepreneurs

In the context urban Sri Lanka the challenge in getting female-owned, subsistence-level microenterprises to grow may lie outside the realm of capital and skills. Results of the training and capital access intervention are somewhat more encouraging in terms of helping women who are outside the labour force to start enterprises more quickly.
