We analyze the design of a mechanism to extract a ranking of individuals according to a unidimensional characteristic, such as ability or need. Individuals, connected on a social network, only have local information about the ranking. We show that a planner can construct an ex post incentive...

We present a novel algorithm to rank smaller academic entities such as university departments or research groups within a research discipline. The Weighted Top Candidate (WTC) algorithm is a generalisation of an expert identification method. The axiomatic characterisation of WTC shows why it is...

Who’s the Greatest Of All Times, be it a team or an athlete, is hotly debated among sport fans. To provide a tentative answer, we apply the mathematical concept of network centrality upon the paired comparison model. We capture the twin notions of fitness and prestige across epochs in order to...

A principal incentivizes a team of agents to work by privately offering them bonuses contingent on team success. We study the principal's optimal incentive scheme that implements work as a unique equilibrium. This scheme leverages rank uncertainty to address strategic uncertainty. Each agent is...

One characteristic feature of central banks today is that policy decisions are almost exclusively made by a committee rather than by a single policy maker. Another is that central banks are considerably more transparent than they used to be. Together, this has brought to the fore an important...

A new economic model for analysis of scholarly publishing — journal publishing in particular — is proposed that draws on club theory. The standard approach builds on market failure in the private production (by research scholars) of a public good (new scholarly knowledge). In that model...

An analysis of journal rankings based on five commonly used bibliometric indicators (impact factor, article influence score, Source Normalized Impact per Paper, SCImago Journal Rank, and the Hirsch index) has been conducted. It is shown that despite a high correlation, these single...

I measure information on distinct facets of quality from a corpus of reviews and characterize how decision-makers integrate this information present in text with that available through other channels. Specifically, I demonstrate that referee comments at a scholarly journal contain information on...

Social media is an important source of product information for many users. Marketing in social media is based not only on building a community around the brand, but social media is used as a way to reach a defined group of users with a marketing message. These users are shown content, including...
