Identification, Estimation and Inference Based on Constructed Instruments
Chaohua Dong, Jiti Gao, Oliver Linton +1
We propose a structural projection (SP) method for identifying and estimating structural parameters in regression models associated with endogenous regressors. The method projects…
Estimation and Inference for a Class of Generalized Hierarchical Models
Chaohua Dong, Jiti Gao, Bin Peng +1
In this paper, we consider estimation and inference for the unknown parameters and function involved in a class of generalized hierarchical models. Such models are of great interes…
Smoothing the Nonsmoothness
Chaohua Dong, Jiti Gao, Bin Peng +1
To tackle difficulties for theoretical studies in situations involving nonsmooth functions, we propose a sequence of infinitely differentiable functions to approximate the nonsmoot…
Robust M-Estimation for Additive Single-Index Cointegrating Time Series Models
Chaohua Dong, Jiti Gao, Yundong Tu +1
Robust M-estimation uses loss functions, such as least absolute deviation (LAD), quantile loss and Huber's loss, to construct its objective function, in order to for example eschew…
Multiple-index Nonstationary Time Series Models: Robust Estimation Theory and Practice
Chaohua Dong, Jiti Gao, Bin Peng +1
This paper proposes a class of parametric multiple-index time series models that involve linear combinations of time trends, stationary variables and unit root processes as regress…
On the Time Trend of COVID-19: A Panel Data Study
Chaohua Dong, Jiti Gao, Oliver Linton +1
In this paper, we study the trending behaviour of COVID-19 data at country level, and draw attention to some existing econometric tools which are potentially helpful to understand…
Estimation for single-index and partially linear single-index integrated models
Chaohua Dong, Jiti Gao, Dag Tjøstheim
Estimation mainly for two classes of popular models, single-index and partially linear single-index models, is studied in this paper. Such models feature nonstationarity. Orthogona…
