The Government Spending Multiplier at the Zero Lower Bound: Evidence from the United States

open access: yesOxford Bulletin of Economics and Statistics, Volume 82, Issue 6, Page 1262-1294, December 2020., 2020
Abstract We estimate state‐dependent government spending multipliers for the United States. We use a factor‐augmented interacted vector autoregression (FAIVAR) model. This allows us to capture the time‐varying monetary policy characteristics including the recent zero interest rate lower bound (ZLB) state, to account for the state of the business cycle ...
