We analyze optimal monetary policy under commitment in an economy with uninsurable idiosyncratic risk, long-term nominal bonds and costly inflation. Our model features two transmission channels of monetary policy: a Fisher channel, arising from the impact of inflation on the initial price of...

We build a no-arbitrage model of the yield curves in a heterogeneous monetary union with sovereign default risk, which can account for the asymmetric shifts in euro area yields during the Covid-19 pandemic. We derive an affine term structure solution, and decompose yields into term premium and...

We analyze monetary policy in a New Keynesian model with heterogeneous firms and financial frictions. Firms differ in their productivity and net worth and face collateral constraints that cause capital misallocation. TFP endogenously depends on the time-varying distribution of firms. Although a...

We analyze the impact of introducing a central bank-issued digital currency (CBDC) on the operational framework of monetary policy and the macroeconomy as a whole. To this end, we develop a New Keynesian model with heterogeneous banks, a frictional interbank market, a central bank with deposit...
