Estimating the trend in US real GDP using the trend filtering

Abstract

Using non-Gaussian state-space models, Perron and Wada (2009, Journal of Monetary Economics, 56, 749–765) obtained a nearly piecewise linear trend estimate of US real gross domestic product such that its slope changed around 1973. Such a trend may be regarded as a result of occasional permanent shocks to the growth rate. This article shows that the $${\ell _1}$$ℓ1 trend filtering, which is quite similar to the Hodrick–Prescott filtering and is a type of the recently popular lasso regression, yields almost the same trend estimate, and discusses the reason why this occurs.
