α: calibrated so average coauthorship-adjusted count equals average raw count
We study the role of preferred habitat in understanding the economic effects of the Federal Reserve’s quantitative easing (QE). Using high-frequency identification and exploiting the structure of the primary market for US Treasuries, we isolate demand shocks that are transmitted solely through preferred habitat channels but otherwise mimic QE shocks. We document large localized yield curve effects when financial markets are disrupted. Our calibrated model, which embeds preferred habitat in a New Keynesian framework, can largely account for the observed financial effects of QE. QE is modestly stimulative for output and inflation, but alternative policy designs can generate stronger effects.
