Monetary policy and financial shocks in an empirical small open-economy DSGE model

Determine the optimal response of a small open economy's central bank to financial shocks that lead to increases in credit spreads. Increasing credit spreads reduce the efficacy of monetary policy when the central bank is reducing the policy rate to accommodate a lowering in economic activity.Used a DSGE model that incorporates heterogeneous households and financial intermediaries. Financial shocks leads to an increase in non-performing loans, which in turn causes the financial intermediary to increase the spread over the policy rate at which it is willing to lend.The central bank should reduce the policy rate in response to rising credit spreads, however this response is more muted when compared to a closed economy facing a similar shock.
