Estimating Counterfactual Matrix Means with Short Panel Data
écrit avec Co-author: Brad Ross
We develop a more flexible approach for identifying and estimating average counterfactual outcomes when several but not all possible outcomes are observed for each unit in a large cross section. Such settings include event studies and studies of outcomes of "matches" between agents of two types, e.g. workers and firms or people and places. When outcomes are generated by a factor model that allows for low-dimensional unobserved confounders, our method yields consistent, asymptotically normal estimates of counterfactual outcome means under asymptotics that fix the number of outcomes as the cross section grows and general outcome missingness patterns, including those not accommodated by existing methods. Our method is also computationally efficient, requiring only a single eigendecomposition of a particular aggregation of any factor estimates constructed using subsets of units with the same observed outcomes. In a semi-synthetic simulation study based on matched employer-employee data, our method performs favorably compared to a Two-Way-Fixed-Effects-model-based estimator.

Optimal Allowance with Limited Auditing Capacity
We analyze the mechanism-design problem of a principal allocating amounts of a perfectly divisible good to $n$ agents, each of whom desires as much of the good as possible. The principal has an ideal allocation for each agent, which is private information held by that agent. The principal has access to an auditing technology that allows her to perfectly uncover the private information of any $k$ ($

Migration policy backlash, identity and integration of second-generation migrants in France
Do integration policies that require migrants to demonstrate allegiance lead to more or less integration into the host society? In this paper, we study the effects of a symbolic change in birthright citizenship rules in France on the integration of second-generation immigrants. We exploit an exogenous reform that required second-generation immigrants to declare their willingness to become French as a condition to naturalize. Adopting a Difference-in-Differences approach, we show that, contrary to its stated aim of fostering a greater sense of belonging, this symbolic policy led to a loss of national identity and an increase in perceptions of discrimination among the target group. We document that these effects are not driven by changes in naturalization rates or an increased general hostility. We also show that while the reform did not affect their economic or political integration, it did reduce their cultural integration. Overall, rather than promoting integration, such migration policies can lead to a backlash

Are We Consuming Too Much Groundwater?
We study the optimality of human groundwater consumption. Groundwater is among the world's most important natural resources, but some prominent groundwater aquifers have declining levels because human use exceeds recharge. For each of the world's groundwater aquifers, we use remote sensing and administrative data to estimate dynamic programming models of water extraction, then we recover discount factors that rationalize observed groundwater extraction. About two-thirds of the world's aquifers are extracted at inefficiently high extraction rates, though the remainder have approximately dynamically optimal extraction rates. The welfare loss from excess current global extraction is several trillion dollars.
