Asymmetric Platform Oligopoly

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT We propose a tractable model of asymmetric platform oligopoly with logit demand in which users from two distinct groups are subject to within‐group and cross‐group network effects and decide which platform to join. We characterize the equilibrium when platforms manage user access by setting participation fees for each user group.

A conceptual framework for revealing rare bacterial species in the gut microbiome through guided data transformation: Beyond enterotypes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The gut microbiota is increasingly recognized as a rich source of biological data that offers critical information on host health, including information on pathological conditions such as cancer, diabetes and other metabolic disorders. Inferring host health from gut bacterial composition using statistical analytical methods remains a challenge.

Resource windfalls and political sabotage: Evidence from 5.2 million political ads

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study the role of incentives in inducing sabotage in political contents, vis‐à‐vis natural resource windfalls. The latter induce plausibly exogenous increases in contests' stakes by extending opportunities for policy implementation or private gain upon winning and enhancing incumbent advantage.

What are the carbon services from cover‐crop adoption worth from farmers' perspective?

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We derive shadow prices of carbon services provided by cover crops relative to non‐cover‐crop agricultural practices, accounting for carbon sequestration and greenhouse gas (GHG) emissions. We model the agricultural technology by integrating crop production, carbon sequestration, and GHG emissions.

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Graphic anthropology has grown to become a distinctive subfield at the intersection of anthropology of drawing, visual anthropology, and multimodal approaches to social research. We assess this development and identify two emerging styles of graphic anthropological practice.
