This paper considers semiparametric efficient estimation of conditional moment models with
possibly nonsmooth residuals in unknown parametric components (θ) and unknown
functions (h) of endogenous variables. We show that:(1) the penalized sieve minimum ...

Abstract: This paper studies nonparametric estimation of conditional moment restrictions in
which the generalized residual functions can be nonsmooth in the unknown functions of
endogenous variables. This is a nonparametric nonlinear instrumental variables (IV) ...

Abstract. In a dynamic economy, I characterize the fiscal policy of the government when it
levies distortionary taxes and issues defaultable bonds to finance its stochastic expenditure.
Households predict the possibility of default, generating endogenous debt limits that ...

Abstract This paper considers the estimation of an unknown function h that can be
characterized as a solution to a nonlinear operator equation mapping between two infinite
dimensional Hilbert spaces. The nonlinear operator is unknown but can be consistently ...

Abstract We study repeated elections where privately-informed voters learn to make
decisions based on previous experience. Learning takes place from a biased sample
because the consequences of unchosen past alternatives (ie, counterfactuals) are not ...

We study estimation and model selection of semiparametric models of multivariate survival
functions for censored data, which are characterized by possibly misspecified parametric
copulas and nonparametric marginal survivals. We obtain the consistency and root-n ...

Abstract This paper develops a general equilibrium model of sovereign debt with
endogenous default. Foreign lenders fear that the probability model which dictates the
evolution of the endowment of the borrower is misspecified. To compensate for the risk ...

Abstract This paper considers inference on functionals of semi/nonparametric conditional
moment restrictions with possibly nonsmooth generalized residuals. These models belong
to the difficult (nonlinear) ill-posed inverse problems with unknown operators, and include ...

Abstract We propose a new model of elections where a continuum of voters have private
information about the uncertain performance of electoral alternatives. A (retrospective)
voting equilibrium formalizes the idea that a large number of voters choose between ...

In this online supplemental document, we first provide a brief summary of commonly used
function spaces and sieve spaces. We then provide mathematical proofs of all the theorems,
corollaries, propositions and lemmas that appear in the main text and the appendix of “ ...

Abstract We use a dynamic learning model to investigate different behavioral assumptions in
voting environments with private information. We show that a simple rule, where players
learn based on the outcomes of past elections in which they were pivotal but requires no ...

This paper studies nonparametric estimation of conditional moment restrictions in which the
generalized residual functions can be nonsmooth in the unknown functions of endogenous
variables. This is a nonparametric nonlinear instrumental variables (IV) problem. We ...

Abstract A presumed benefit of group decision-making is to select the best alternative by
aggregating privately dispersed information. In reality, people often learn to make decisions
based on previous experience. When the consequences of unchosen past alternatives (ie, ...

Abstract I analyze the optimal taxation problem under incomplete markets allowing for partial
defaults on the government debt, and for secondary markets wherein households trade the
defaulted debt. Households predict this possibility of default generating endogenous debt ...
