Nonparametric and Semiparametric Panel Econometric Models: Estimation and Testing
نویسندگان
چکیده
This paper gives a selective review on the recent developments of nonparametric and semiparametric panel data models. We focus on the conventional panel data models with one-way error component structure, partially linear panel data models, varying coe¢ cient panel data models, nonparametric panel data models with multi-factor error structure, and nonseparable nonparametric panel data models. For each area, we discuss the basic models and ideas of estimation, and comment on the asymptotic properties of di¤erent estimators and speci cation tests. Much theoretical and empirical research is needed in this emerging area. KEY WORDS: Cross section dependence; xed e¤ects; hypothesis testing; nonadditive model; nonparametric GMM; nonseparable model; partially linear panel data model; random e¤ects; varying coe¢ cient model; The rst author gratefully acknowledges the nancial support from the NSFC under the grant numbers 70501001 and 70601001.

Nonparametric estimation and testing of fixed effects panel data models.
In this paper we consider the problem of estimating nonparametric panel data models with fixed effects. We introduce an iterative nonparametric kernel estimator. We also extend the estimation method to the case of a semiparametric partially linear fixed effects model. To determine whether a parametric, semiparametric or nonparametric model is appropriate, we propose test statistics to test betw...

Moment restriction-based econometric modelling is a broad class which includes the parametric, semiparametric and nonparametric approaches. Moments and conditional moments themselves are nonparametric quantities. If a model is specified in part up to some finite dimensional parameters, this will provide semiparametric estimates or tests. If we use the score to construct moment restrictions to e...
متن کاملFunctional Form of the Environmental Kuznets Curve
This paper provides an overview of recent econometric advances on testing of functional form with semiparametric methods and their application to the estimation of the environmental Kuznets curve (EKC). The EKC in environmental economics is estimated using panel data models and provides a fertile ground for the adoption of recent panel data developments. The paper provides a discussion of recen...
متن کاملNon - and Semi - Parametric Panel Data Models : A Selective Review
This article provides a selective review on the recent developments of some nonlinear nonparametric and semiparametric panel data models. In particular, we focus on two types of modelling frameworks: nonparametric and semiparametric panel data models with deterministic trends, and semiparametric single-index panel data models with individual effects. We also review various estimation methodolog...
متن کاملM-testing Using Finite and Infinite Dimensional Parameter Estimators by Halbert White And
The m-testing approach provides a general and convenient framework in which to view and construct speci cation tests for econometric models. Previous m-testing frameworks only consider test statistics that involve nite dimensional parameter estimators and in nite dimensional parameter estimators a ecting the limit distribution of the m-test statistics. In this paper we propose a new m-testing f...
