As countries develop, the main driver of economic growth shifts from imitation to innovation. These two sources of growth require different policies and institutions. In particular, in this article we argue that the transition from an imitation-based to an innovation-based economy calls the old...

This paper is about the effectiveness of qualitative easing; a government policy that is designed to mitigate risk through central bank purchases of privately held risky assets and their replacement by government debt, with a return that is guaranteed by the taxpayer. Policies of this kind have...

In this paper we provide a model of the macroeconomic consequences of a shortage of safe assets. In particular, we discuss the emergence of a deflationary safety trap equilibrium which is an acute form of a liquidity trap. In this context, issuing public debt, swapping private risky assets for...

Trust in policy makers fluctuates significantly over the cycle and affects the transmission mechanism. Despite this it is absent from the literature. We build a monetary model embedding trust cycles; the latter emerge as an equilibrium phenomenon of a game-theoretic interaction between atomistic...

A market for used capital goods, or financial instruments that represent the ownership of the used capital goods, induces inflation taxes on wealth and on the nominal income flows they provide. This paper explicitly introduces trading in either used capital goods or financial instruments into...

Purpose – The latest generation of research into macroeconomic policy has turned from more technical aspects of optimal control and expectations formation to consideration of the policymaking institutions themselves. More and more countries have moved towards greater degrees of central bank...

Financial assets provide return and liquidity services to their holders. However, during severe financial crises many asset prices plummet, destroying their liquidity provision function at the worst possible time. In this paper we present a model of fire sales and market breakdowns, and of the...

This paper focuses on simple normative rules for monetary policy that central banks can use to guide their interest rate decisions. Such rules were first derived from research on empirical monetary models with rational expectations and sticky prices built in the 1970s and 1980s. During the past...

The purpose of this paper is to discuss some of the models used in New Monetarist Economics, which is our label for a body of recent work on money, banking, payments systems, asset markets, and related topics. A key principle in New Monetarism is that solid microfoundations are critical for...

This paper builds on Baqaee and Farhi (2022) and di Giovanni et al. (2022) to quantify the contribution of fiscal policy on U.S. inflation over the Dec-2019 to June-2022 period. Model calibrations show that aggregate demand shocks explain roughly two-thirds of total model-based inflation, and...
