“…The extent of central banks' unconventional monetary policies has fostered a recent strand of literature that focuses on their unintended consequences, ranging from the effect on bond market liquidity (Pelizzon, Subrahmanyam, Tomio, and Uno, 2016;Pelizzon, Subrahmanyam, Tobe, and Uno, 2017;Schlepper, Hofer, Riordan, and Schrimpf, 2017;Christensen and Gillan, 2018), to the functioning of the repo markets (D'Amico, Fan, and Kitsul, 2015;Corradin and Maddaloni, 2017), to the QE's effect on the real economy (Acharya, Eisert, Eufinger, and Hirsch, 2017;Crosignani, Faria-e Castro, and Fonseca, 2017;Daetz, Subrahmanyam, Tang, and Wang, 2017). We contribute to this developing strand of literature by analyzing the effect of QE interventions on the actual arbitrage relationship and the mispricing between the assets the central bank is heavily purchasing and another prominent asset class.…”
