Abstract: The European Central Bank and the Federal Reserve introduced new policy instruments and made changes to their operational frameworks to address the global financial crisis (2008) and the Covid-19 pandemic (2020). We study the macroeconomic effects of these monetary policy evolutions on both sides of the Atlantic Ocean by developing and estimating a tractable two-country dynamic stochastic general equilibrium model. We show that the euro area and the United States faced shocks of different natures, explaining some asynchronous monetary policy measures between 2008 and 2023. However, counterfactual exercises highlight that all conventional and unconventional policies implemented since 2008 have appropriately (i) supported economic growth and (ii) maintained inflation on track in both areas. The exception is the delayed reaction to the inflationary surge during 2021-2022. Furthermore, exchange rate shocks played a significant role in shaping the overall monetary conditions of the two economies.
