R&D investment spending exhibits a delayed and hump-shaped response to shocks. We show in a simple partial equilibrium model that rapidly adjusting R&D investment is costly if the probability of converting new hires into productive R&D workers (“onboarding”) is decreasing in the number of...

We develop a novel, tractable New Keynesian model where firms post wages and workers search on the job, motivated by microeconomic evidence on wage setting. Because firms set wages to avoid costly turnover, the rate that workers quit their jobs features prominently in the model's wage Phillips...

Legal academics, journalists, and senior executive branch officials alike have assumed that the cost of imposing new regulatory requirements is higher in severe recessions that drive the central bank's policy rate to zero than in other times. This is not correct; the aggregate output costs of...

We examine the standard New Keynesian economy's Ramsey problem written in terms of instrument settings instead of allocations. Its standard formulation makes two instruments available: the path of current and future interest rates, and an "open mouth operation" which selects one of the many...

New Keynesian economies with active interest rate rules gain equilibrium determinacy from the central bank's incredible off-equilibrium-path promises (Cochrane, 2011). We suppose instead that the central bank sets interest rate paths and occasionally has the discretion to change them. Private...

Though most central banks actively intervene on the foreign exchange market, the literature offers mixed evidence on their effectiveness: particularly for unannounced interventions. We use new, declassified data from the archives of the Bank of England and the institutional features of the...

Legal academics, journalists, and senior executive branch officials alike have assumed that the economic costs of regulatory requirements go up in severe recessions that drive interest rates to zero. But this is not correct; the aggregate costs of regulatory requirements decrease, not increase,...
