Motivated by the fact that a linear speci fication in a quantile regression setting is unable to describe the non-linear relations among economic variables, as documented in the empirical econometrics literature, we are the first to formulate and analyze a multiple threshold quantile regression...

This paper extends Kiefer, Vogelsang, and Bunzel - (2000, Econometrica) and Kiefer and Vogelsang - (2002b, Econometric Theory) to propose a class of over-identifying restrictions (OIR) tests that are robust to heteroskedasticity and serial correlations of unknown form. These OIR tests do not...

Motivated by the fact that a linear specification in a quantile regression setting is unable to describe the non-linear relations among economic variables, well documented in the empirical econometrics literature, we formulate a threshold quantile regression model for one, known and unknown...

In this paper, a simultaneous equation model with an endogenous variable and an exogenous threshold variable is analysed and estimated thereby extending Caner and Hansen (2004) model to quantile regression. In our framework, we allow both the reduced-form and the structural equation to exhibit...
