We investigate the extent to which misperceptions about the economy can become self-reinforcing and thereby contribute to time-varying macroeconomic dynamics. To do so, we build a New Keynesian model with long-horizon expectations and dynamic predictor selection. Because agents solve...

In this paper, we compare two approaches to modelling behaviour under non-rational expectations in a benchmark New Keynesian model. The ‘Euler equation' approach modifies the equations derived under the assumption of rational expectations by replacing the rational expectations operator with an...

Determinacy is ensured in the New Keynesian model when firms face imperfect common knowledge, regardless of whether the Taylor principle is satisfied. Strategic complementarity in pricing and idiosyncratic noise in firms' signals, however small, are together sufficient to eliminate...

We develop a model that can explain the evolution of trend inflation in the United States in the three decades before the Great Recession as a function of the reduction in uncertainty about the monetary policy maker's behaviour. The model features ambiguity-averse agents and ambiguity regarding...

I present a model of social learning over an exogenous, directed network that may be readily nested within broader macroeconomic models with dispersed information and combines the attributes that agents (a) act repeatedly and simultaneously; (b) are Bayes-rational; and (c) have strategic...

Modifying the standard New-Keynesian model to replace firms' full information and sticky prices with flexible prices and dispersed information, and imposing mild and plausible restrictions on the monetary authority's decision rule, produces the striking results that (i) there exists a unique and...

The purpose of this paper is to examine how important an improvement in global monetary policy might be for the macroeconomic performance of a small open economy such as the United Kingdom. Our paper contributes to the literature by proposing a new methodology to treat indeterminate solutions...

We analyse the impact of Covid-19 on productivity using data from an innovative monthly firm survey panel that asks for quantitative impacts of Covid on inputs and outputs. We find total factor productivity (TFP) fell by up to 5% during 2020–21. The overall impact combined large reductions in...

We use data from a large panel survey of UK firms to analyze the economic drivers of price setting since the start of the Covid pandemic. Inflation responded asymmetrically to movements in demand. This helps to explain why inflation did not fall much during the negative initial pandemic demand...

Public policies aimed at mitigating climate change can come with the transition risk of sudden adjustments of asset prices. We study the consequences of a policy intervention addressing greenhouse gas emissions in the housing market. Leveraging a unique data set of the population of all house...
