Business Influence on Democratization

My dissertation is a comprehensive evaluation of how businesses build coalitions for and against democratization in North Africa. I mix intensive field research with online survey experiments to gain new insights into how businesspeople influence politics in emerging democracies.

Rethinking Two-way Fixed Effects: A Generative Model and Simulation for Time-Series Cross-Section Data

Despite their popularity, linear fixed effects models can be a painful experience for applied researchers. Our paper shows that some of these problems stem from the wide application of the two-way fixed effects model as opposed to the simpler and easier to interpret one-way fixed effects models.

Absence Makes the Ideal Points Sharper: An Ordinal IRT Model for Complete-Data Rollcall Vote Modeling

I put forward a Bayesian IRT model that is capable of handling legislator absence as a form of data that can increase the precision of ideal point estimates.

This is a paper that was presented at the StanCon2018 conference on Bayesian inference with the Stan Hamiltonian Markov Chain Monte Carlo (MCMC) method. Video of my talk is available here. Introduction This notebook introduces idealstan, a new R package front-end to Stan that allows for flexible modeling of a class of latent variable models known as ideal point models. Ideal point modeling is a form of dimension reduction, and shares similarities with multi-dimensional scaling, factor analysis and item-response theory.
