Employment, Wages and Optimal Monetary Policy
We study optimal monetary policy when the empirical evidence leaves the policymaker uncertain whether the true data-generating process is given by a model with sticky wages or a model with search and matching frictions in the labor market. Unless the policymaker is almost certain about the search and matching model being the correct data-generating process, the policymaker chooses to stabilize wage inflation at the expense of price inflation, a policy resembling the policy that is optimal in the sticky wage model, regardless of the true model. This finding reflects the greater sensitivity of ...

On Targeting Frameworks and Optimal Monetary Policy
Speed limit policy, a monetary policy strategy that focuses on stabilizing inflation and the change in the output gap, consistently delivers better welfare outcomes than flexible inflation targeting or flexible price level targeting in empirical New Keynesian models when policymakers lack the ability to commit to future policies. Even if the policymaker can commit under an inflation targeting strategy, the discretionary speed limit policy performs better for most empirically plausible model parameterizations from a normative perspective.

Optimal Monetary and Fiscal Policy under Limited Foresight
We investigate Barro's random walk hypothesis according to which distortionary labor taxes should follow a random walk for any stochastic process of government expenditures, see Barro (1979). When agents experience cognitive discounting as in Gabaix (2020), they perceive government debt as wealth, and the random walk result breaks down except for knife-edge combinations of limited rationality by policymakers and the private sector. For these specific parameter values, the result can reemerge, but minor deviations from these knife-edge combinations lead to stationary equilibrium dynamics, ...
