We provide estimation methods for panel nonseparable models based on low-rank factor structure approximations. The factor structures are estimated by matrix-completion methods to deal with the computational challenges of principal component analysis in the presence of missing data. We show that the resulting estimators are consistent in large panels, but suffer from approximation and shrinkage biases. We correct these biases using matching and difference-in-difference approaches. Numerical… Expand

Square-root nuclear norm penalized estimator for panel data models with approximately low-rank unobserved Heterogeneity
This paper considers a nuclear norm penalized estimator for panel data models with interactive effects. The low-rank interactive effects can be an approximate model and the rank of the bestExpand
Inference for Heterogeneous Effects using Low-Rank Estimation of Factor Slopes
We study a panel data model with general heterogeneous effects where slopes are allowed to vary across both individuals and over time. The key dimension reduction assumption we employ is that theExpand
Rank regularized estimation of approximate factor models
It is known that the common factors in a large panel of data can be consistently estimated by the method of principal components, and principal components can be constructed by iterative leastExpand

This paper is concerned with extending the familiar notion of fixed effects to nonlinear setups with infinite dimensional unobservables like preferences. The main result is that a generalized versionExpand
Robust Synthetic Control
TLDR
The condition under which the fundamental assumption in synthetic control-like approaches holds holds is established, i.e. when the linear relationship between the treatment unit and the donor pool prevails in both the pre- and post-intervention periods. Expand
Nonlinear Factor Models for Network and Panel Data
TLDR
It is established that fixed effect estimators of model parameters and average partial effects have normal distributions when the two dimensions of the panel grow large, but might suffer of incidental parameter bias. Expand
Weighted Low-Rank Approximations
TLDR
This work provides a simple and efficient algorithm for solving weighted low-rank approximation problems, which, unlike their unweighted version, do not admit a closed-form solution in general. Expand
