While the literature on nonclassical measurement error traditionally relies on the availability
of an auxiliary data set containing correctly measured observations, we establish that the
availability of instruments enables the identification of a large class of nonclassical ...

This paper provides a general solution to the problem of identification and estimation of
nonlinear models with misclassification error in a general discrete explanatory variable
using instrumental variables. The misclassification error is allowed to be correlated with all ...

This article compares risk reduction from MPCI and GRP crop insurance contracts. The
analysis extends and improves on the existing area-yield insurance literature in four
important respects. First, the geographical scope greatly exceeds that of previous work. ...

Abstract We consider the identification of a Markov process {Wt, X∗ t} when only {Wt} is
observed. In structural dynamic models, Wt includes the choice variables and observed state
variables of an optimizing agent, while X∗ t denotes time-varying serially correlated ...

This case study describes the potential use of new risk-sharing instruments (Skees, Skees

Dakota. These instruments are discussed in the context of members' crop yield risk. Zeuli, ...

Abstract This paper considers the problem of consistent estimation of nonlinear models with
mismeasured explanatory variables, when marginal information on the true values of these
variables is available. The marginal distribution of the true variables is used to identify the ...

Abstract We propose a novel methodology for nonparametric identification of first-price
auction models with independent private values, which accommodates auction-specific
unobserved heterogeneity and bidder asymmetries, based on recent results from the ...

In this paper, we consider nonparametric identification and estimation of first-price auction
models when N∗, the number of potential bidders, is unknown to the researcher, but
observed by bidders. Exploiting results from the recent econometric literature on models ...

We consider the estimation of nonlinear models with mismeasured explanatory variables,

This paper discusses a linear regression model with a mismeasured regressor in which the
measurement error is correlated with both the latent variable and the regression error. We
use a linear structure to capture the correlation between the measurement error and the ...

Abstract This paper considers nonparametric identification of nonlinear dynamic models for
panel data with unobserved covariates. Including such unobserved covariates may control

We observe a dependent variable and some regressors, including a mismeasured binary
regressor. We provide identification of the nonparametric regression model containing this
misclassified dichotomous regressor. We obtain identification without parameterizations or ...

We reconsider Taupin's (2001) Integrated Nonlinear Regression (INLR) estimator for a
nonlinear regression with a mismeasured covariate. We find that if we restrict the distribution
of the measurement error to a class of distributions with restricted support, then much ...

Abstract Anecdotal evidence has suggested increased fertility rates resulting from
catastrophic events in an area. In this paper, we measure this fertility effect using storm
advisory data and fertility data for the Atlantic and Gulf-coast counties of the USA. We find ...

Abstract It is widely admitted that the inverse problem of estimating the distribution of a latent
variable X∗ from an observed sample of X, a contaminated measurement of X∗, is a
Fredholm integral equation of the first kind and illposed. This paper shows that such ...

Abstract In this paper we consider the nonparametric identification of Markov dynamic

Abstract This note establishes that the fully nonparametric classical errors-in-variables
model is identifiable from data on the regressor and the dependent variable alone, unless
the specification is a member of a very specific parametric family. This family includes the ...

This note considers a nonlinear regression model containing a 0–1 dichotomous regressor
when it is subject to arbitrary measurement errors in the sample. The key identification
assumption requires that the third conditional moment of the regression error is zero. This ...
