Abstract:  

We study optimal exchange rate stabilization in a tractable Small Open HANK Economy with endogenous consumption risk and rich cross-sectional inequalities. Besides the closed-economy channels, aggregate demand management operates through the real exchange rate, which affects both GDP (through expenditure switching) and national income (through the relative price of foreign goods) and ultimately feeds back to domestic cross-sectional heterogeneity. We show that these open-economy channels require stabilizing the exchange rate substantially more in HANK than in RANK after aggregate productivity shocks; this is because stabilizing the exchange rate mitigates expenditure switching and the implied fluctuations in domestic inequalities. The same is true in response to capital-flow shocks, provided that agents are sufficiently risk-averse.
