Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

American Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Why are surveys struggling to estimate vote shares?

American Journal of Political Science, EarlyView.
Abstract Polling in the 2020 US presidential elections significantly underestimated Trump support, calling into question the accuracy of all political surveys. Although many have speculated that this bias is due to Trump supporters refusing to respond to surveys, we have previously lacked the data to directly evaluate this theory.

Long‐run confidence: Estimating uncertainty when using long‐run multipliers

American Journal of Political Science, EarlyView.
Abstract Researchers are often interested in the long‐run relationship (LRR) between variables where the dependent variable has dynamic properties. Though determining the long‐run multiplier (LRM) for an independent variable is straightforward, correctly estimating the significance of the LRM is often difficult, especially when time series are short ...

Endogenous coalition formation in policy debates

American Journal of Political Science, EarlyView.
Abstract Political actors form coalitions around their joint normative beliefs in order to influence the policy process on contentious issues such as climate change or population aging. Policy process theory maintains that learning within and across coalitions is a central predictor of policy change but has yet to explain how policy learning works ...
