Using an estimated DSGE model with monetary and fiscal policy interactions and allowing for equilibrium indeterminacy, we find that a passive monetary and passive fiscal policy regime prevailed in the pre-Volcker period. This gave rise to self-fulfilling beliefs and unconventional transmission mechanisms of policy shifts: unanticipated increases in interest rates increased inflation and output, while unanticipated increases in lump-sum taxes decreased inflation and output. We show that had the m

Using a micro-founded model and a likelihood-based inference method, we show that while a passive monetary and passive fiscal policy regime prevailed in the U.S. before Paul Volcker's chairmanship at the Federal Reserve, an active monetary and passive fiscal policy regime prevailed after his appointment. Since both monetary and fiscal policies were passive pre-Volcker, equilibrium indeterminacy was a feature of the economy. Finally, pre-Volcker, the effects of unanticipated policy shifts were su

We estimate international spillover effects of US Quantitative Easing (QE) on emerging market economies. Using a Bayesian VAR on monthly US macroeconomic and financial data, we first identify the US QE shock with non-recursive identifying restrictions. We estimate strong and robust macroeconomic and financial impacts of the US QE shock on US output, consumer prices, long-term yields, and asset prices. The identified US QE shock is then used in a monthly Bayesian panel VAR for emerging market eco

We study spillover effects of US uncertainty fluctuations using panel data from fifteen emerging market economies (EMEs). A US uncertainty shock negatively affects EME stock prices and exchange rates, raises EME country spreads, and leads to capital outflows from them. Moreover, it decreases EME output, while increasing their consumer prices and net exports. The negative effects on output, exchange rates, and stock prices are weaker, but the effects on capital and trade flows stronger, for South
