I describe nine implications of the interconnectedness of fiscal and monetary policy that surface in Heterogeneous Agent New Keynesian (HANK) models. Not all are unique to HANK models. (i) Long run fiscal changes force monetary adjustments. (ii) Sustainable permanent deficits are feasible. (iii)...

We discuss the evolution in macroeconomic thought on the monetary policy transmission mechanism and present related empirical evidence. The core channels of policy transmission — the neoclassical links between short-term policy interest rates, other asset prices such as long-term interest...

We study equilibria in a heterogeneous-agent incomplete-market economy with nominal government debt and flexible prices. Unlike in representative agent economies, steady-state equilibria exist when the government runs persistent deficits, provided that the level of deficits is not too large. In...

This paper investigates whether OECD countries are facing secular stagnation. Secular stagnation is defined as a situation when policy interest rates bounded at zero fail to stimulate demand sufficiently, due to low or negative neutral real interest rates and low inflation, and when ensuing...

The paper provides an integrated analysis of globalization effects on the inflation-output tradeoff and monetary policy in the New-Keynesian framework. The prediction of the analysis is threefold. First, labor, goods, and capital mobility flatten the Phillips curve, the tradeoff between...

We show that short and long nominal interest rates are independent monetary policy instruments. The pegging of both helps solving the problem of multiplicity that arises when only short rates are used as the instrument of policy. A peg of the nominal returns on assets of different maturities is...

We study the effects of positive steady-state inflation in New Keynesian models subject to the zero bound on interest rates. We derive the utility-based welfare loss function taking into account the effects of positive steady-state inflation and show that steady-state inflation affects welfare...

We develop a quantitative New Keynesian DSGE model with monopolistic banks to study the macroeconomic effects of introducing a central bank digital currency (CBDC). Households benefit from an expansion of liquidity services and higher deposit rates as bank deposit market power is curtailed,...

I use the valuation equation of government debt to understand fiscal and monetary policy in and following the great recession of 2008-2009, to think about fiscal pressures on US inflation, and what sequence of events might surround such an inflation. I emphasize that a fiscal inflation can come...

Questo lavoro analizza le due ipotesi che sostengono l'introduzione dei vincoli sugli afflussi di capitale in caso di crisi finanziaria: la prima è che le crisi siano legate ad un eccessivo indebitamento di breve periodo, la seconda è che i vincoli asimmetrici alterino la maturità del debito....
