China has undergone extensive reform of its business system in its rapid transition to a market economy. In this process, the success of enterprises has depended heavily on changing structural conditions, such as the transformation of ownership and market competition, on the ability of...

We explore the validity of the 2-stage least squares estimator with l_{1}-regularization in both stages, for linear regression models where the numbers of endogenous regressors in the main equation and instruments in the first-stage equations can exceed the sample size, and the regression...

We explore the validity of the 2-stage least squares estimator with l_{1}-regularization in both stages, for linear triangular models where the numbers of endogenous regressors in the main equation and instruments in the first-stage equations can exceed the sample size, and the regression...

We develop simple and non-asymptotically justified methods for hypothesis testing about the coefficients ($\theta^{*}\in\mathbb{R}^{p}$) in the high dimensional generalized regression models where $p$ can exceed the sample size. Given a function $h:\,\mathbb{R}^{p}\mapsto\mathbb{R}^{m}$, we...

We develop simple and non-asymptotically justified methods for hypothesis testing about the coefficients ($\theta^{*}\in\mathbb{R}^{p}$) in the high dimensional (generalized) regression models where $p$ can exceed the sample size $n$. Given a function $h:\,\mathbb{R}^{p}\mapsto\mathbb{R}^{m}$,...

We develop non-asymptotically justified methods for hypothesis testing about the p-dimensional coefficients in (possibly nonlinear) regression models, where the hypotheses can also be nonlinear in the coefficients. Our (nonasymptotic) control on the Type I and Type II errors holds for fixed n...

At the macro-level, economic reform in the PRC since 1978 has led to the implementation of a multi-ownership system. The consequent transformation of Chinese formerly state-owned enterprises (SOEs) has been a major way of improving efficiency and increasing competition. However, the...

Indonesia is facing a rapid institutional change arising from the 1997 Asian Crisis, and state-owned enterprises (SOEs) were forced to undertake a transformation to survive in the increasing market competition and to revive their roles as the engine of economic growth. This included measures to...

This paper explores the validity of the two-stage estimation procedure for sparse linear models in high-dimensional settings with possibly many endogenous regressors. In particular, the number of endogenous regressors in the main equation and the instruments in the first-stage equations can grow...

We explore the validity of the 2-stage least squares estimator with l1−regularization in both stages, for linear models where the numbers of endogenous regressors in the main equation and instruments in the first-stage equations can exceed the sample size, and the regression coefficients...
