• Excellent crash-course in multisite experiments and estimators for site-specific effects
• DML for covariate shifts (now with more authors)
• Now classic paper (thanks publication timelines) on estimating direct and indirect effects of public employment programs
• bayesian sparse PCA with a spike and slab prior (variational inference because they want people to use it)
• matrix factorisation for large scale discrete choice problems with variational inference
• Bias-reducing adjustments to M-estimation using ideas from robust statistics
• bias-aware inference on (a class of somewhat non-standard looking) penalised regression problems
• survey paper on Chatterjee's coefficient of correlation and subsequent work and extensions
• updated version of Hazan's monograph on online convex optimisation
