Model-based RL and Causal Inference:
Leveraging structure on both the policy and the dynamics of an MDP to get sharper lower bounds for off-policy evaluation with unobserved confounding.
Distribution of Wealth in Two Asset Models:
Dynamic models of household wealth with income shocks and both liquid and illiquid assets. Emphasis on the relationship between housing wealth, income uncertainty, and debt.
Income Uncertainty Over Long Horizons
Assessing the predictability of income trajectories over spans of 10-30 years using administrative tax records from Iceland. Emphasis on the joint evolution of income, assets, and housing.
