When the central bank sets monetary policy according to a conventional or modified Taylor rule (which is known as the Taylor Principle), does this deliver the best outcome for the mac-roeconomy as a whole? This question is addressed by extending the wavelet-based control (WBC) model of Crowley...

This paper studies the cost of limited commitment when a central bank has the discretion to adjust policy whenever the costs of honoring its past commitments become high. Specifically, we consider a central bank that seeks to implement optimal policy in a New Keynesian model by committing to a...

Using daily data since 2017, we disentangle China-specific structural shocks driving Chinese financial markets and examine spillovers across global markets. The novelty of this paper consists of simultaneously identifying China shocks with shocks emanating from the United States and shocks to...

This paper studies whether and how banks' technological innovations affect the bank lending channel of monetary policy transmission. We first provide a theoretical model in which banks' technological innovation relaxes firms' earning-based borrowing constraints and thereby enlarges the response...

This paper studies price stability and debt sustainability when the real rate exceeds trend growth (r g) in a New Keynesian model with endogenous technology growth through R&D. Under debt-stabilizing ("passive") fiscal policy the Taylor principle is not sufficient for determinacy. Instead,...

I document a statistical link between old-age dependency ratios and average markups. I propose that a mechanism whereby households develop deep habits in consumption as they age could explain this feature of the data. I show that when this mechanism is embedded in an overlapping generations New...

This paper presents a novel method to estimate the depreciation rate of durable goods using a combination of identified marginal and average spending shares. We apply our method to Chinese spending responses to disposable income changes induced by monetary policy in 2008-2009. The marginal...

We evaluate the effects of targeted credit injections of the central bank in the euro area. The aggregate policy impacts of credit easing on financial markets, bank lending and key macroeconomic variables are measured with a novel identification approach based on high-frequency web search data....

Optimal monetary policy studies typically rely on a single structural model and identification of model-specific rules that minimize the unconditional volatilities of inflation and real activity. In our proposed approach, we take a large set of structural models and look for the model-robust...

This paper studies monetary policy transmission through BigTech and traditional banks. By comparing business loans made by a BigTech bank with those made by traditional banks, it finds that BigTech credit amplifies monetary policy transmission mainly through the extensive margin. Specifically,...
