Impact of uncertainty and exchange rate shocks: Theory and global empirics

Abstract

This paper offers two points on the impact of uncertainty and exchange rate shocks. (1) A conceptual model where behavioural frictions – rational inattentiveness and bounded expectations – interact with uncertainty, generating aggregate fluctuations. Central banks can target these behavioural frictions to stabilise output and prices. (2) Empirical findings from a panel of advanced and emerging economies. Output and inflation slow in response to uncertainty shocks. Government bond yields moderate and exchange rates depreciate, suggesting within-country and between-country flight-to-safety respectively. Exchange rate appreciation shocks generate similar responses. The Malaysia-specific analysis finds divergent responses in employment and output, likely reflecting compositional effects in more productive tradable and less productive non-tradable sectors.
