Infectious diseases are among the main causes of death and disability in developing countries, and they are a major reason for the health disparity between rich and poor countries. One of the reasons for this public health tragedy is a lack of lifesaving essential medicines, which either do not...

With the spread of the internet and new opportunities for publishing academic works digitally at virtually no costs, the traditional copyright model has recently been put under critical review which is for at least two reasons: First and foremost, a vast increase in subscription prices for...

Mandatory data disclosure is an essential feature for credible empirical work but comes at a cost: First, authors might invest less in data generation if they are not the full residual claimants of their data after their first publication. Second, authors might "strategically delay" the time of...

Replication studies are considered a hallmark of good scientific practice. Yet they are treated among researchers as an ideal to be professed but not practiced. To provide incentives and favorable boundary conditions for replication practice, the main stakeholders need to be aware of what drives...

Two “order effects” may emerge in dynamic tournaments with information feedback. First, participants adjust effort across stages, which could advantage the leading participant who faces a larger “effective prize” after an initial victory (leading-effect). Second, participants lagging...

This paper analyzes the effect of open access (OA) status of published journal articles on peer recognition, as measured by the number of citations. Using cross-sectional and panel data from interdisciplinary mathematics and economics journals, we perform negative binomial, Poisson and linear...
