Robert Adamek, Stephan Smeekes, Ines Wilms

AI总结:

该研究针对高维场景下的脉冲响应估计问题,采用不对目标参数施加惩罚的去稀疏lasso实现高维局部投影估计,证明了估计量的一致渐近正态性,并通过模拟及宏观经济典型应用验证了小样本性能。

摘要:

本文在高维环境中通过局部投影法估计脉冲响应。我们采用去稀疏(去偏)lasso估计高维局部投影,同时不对目标脉冲响应参数施加惩罚。我们在一般条件下证明了所提出估计量的一致渐近正态性。最后,我们通过模拟研究验证了其小样本性能,并在货币政策与政府支出的宏观经济研究中考察了两个典型应用。

英文摘要:

In this paper, we estimate impulse responses by local projections in high-dimensional settings. We use the desparsified (de-biased) lasso to estimate the high-dimensional local projections, while leaving the impulse response parameter of interest unpenalized. We establish the uniform asymptotic normality of the proposed estimator under general conditions. Finally, we demonstrate small sample performance through a simulation study and consider two canonical applications in macroeconomic research on monetary policy and government spending.
