Using 2SLS estimation, we propose two tests for a threshold in models with endogenous regressors: a sup LR test and a sup Wald test. Here, the 2SLS estimation is not conventional because it uses additional information about the first-stage being linear or not. Because of this additional information, our tests can be more accurate than the threshold test in Caner and Hansen (2004) which is based on conventional GMM estimation. We derive the asymptotic distributions of the two tests for a linear… 

Dealing With Endogeneity in Threshold Models Using Copulas

The method is robust to nonlinear dependence structures between the regression error term and the threshold variable implied by the Archimedean family of copulas and allows us to consistently estimate the threshold and the slope parameters of the model based on a least squares method.

Multi-Threshold Structural Equation Model

Abstract In this article, we consider the instrumental variable estimation for causal regression parameters with multiple unknown structural changes across subpopulations. We propose a multiple

Inference and Specification Testing in Threshold Regression with Endogeneity

We propose three new methods of inference for the threshold point in endogenous threshold regression and two specii¬ cation tests designed to assess the presence of endogeneity and threshold ei¬€ects

Threshold Regression with Endogeneity

This paper studies estimation and specification testing in threshold regression with endogeneity. Three key results differ from those in regular models. First, both the threshold point and the

STRUCTURAL THRESHOLD REGRESSION

This paper introduces the structural threshold regression (STR) model that allows for an endogenous threshold variable as well as for endogenous regressors. This model provides a parsimonious way of

Testing for Threshold Effects in Regression Models

In this article, we develop a general method for testing threshold effects in regression models, using sup-likelihood-ratio (LR)-type statistics. Although the sup-LR-type test statistic has been

INSTRUMENTAL VARIABLE ESTIMATION OF A THRESHOLD MODEL

Threshold models (sample splitting models) have wide application in economics. Existing estimation methods are confined to regression models, which require that all right-hand-side variables are

Dealing With Endogeneity in Threshold Models Using Copulas

The method is robust to nonlinear dependence structures between the regression error term and the threshold variable implied by the Archimedean family of copulas and allows us to consistently estimate the threshold and the slope parameters of the model based on a least squares method.

Sample Splitting and Threshold Estimation

Threshold models have a wide variety of applications in economics. Direct applications include models of separating and multiple equilibria. Other applications include empirical sample splitting when

Inference When a Nuisance Parameter Is Not Identified under the Null Hypothesis

Many econometric testing problems involve nuisance parameters which are not identified under the null hypotheses. This paper studies the asymptotic distribution theory for such tests. The asymptotic

THRESHOLD AUTOREGRESSION WITH A UNIT ROOT

This paper develops an asymptotic theory of inference for an unrestricted two-regime threshold autoregressive (TAR) model with an autoregressive unit root. We find that the asymptotic null
