Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...

We develop a tractable sticky price model in which the fraction of price changes evolves endogenously over time and, consistent with the evidence, increases with inflation. Because we assume that firms sell multiple products and choose how many, but not which, prices to adjust in any given...

This paper uses a Bayesian estimation approach to examine the behavior of the Sierra Leone’s economy by creating a small-open economy DSGE model that includes financial frictions. The study utilises a New Keynesian framework to examine the actions of diverse economic agents, such as...

We estimate a time-varying parameter vector autoregression to examine the evolution of international spillovers of U.S. monetary policy in light of increasing globalization in real and financial markets. We find that the adverse international effects of a U.S. tightening have substantially...

As part of the green transition, the European cap-and-trade scheme for CO2 emissions will be extended to cover consumer durables. We propose a New Keynesian model that features both, "brown" and "green" durable goods and show that if monetary policy follows a business-as-usual approach, the...

The introduction of a common currency in the Economic Community of West African States (ECOWAS) has been the subject of extensive research over the past couple of decades, with extant issues ranging from viability and feasibility to sustainability of monetary integration in the region. This...

We analyze the optimal window length in the average inflation targeting rule within a Behavioral THANK model. The central bank faces an occasionally binding effective lower bound (ELB) or persistent supply shocks, and can also use quantitative easing. We show that the optimal averaging period is...

This paper introduces a Bayesian Quantile Factor Augmented VAR (BQFAVAR) to examine the asymmetric effects of monetary policy throughout the business cycle. Monte Carlo experiments demonstrate that the model effectively captures non-linearities in impulse responses. Analysis of aggregate...

We analyse cycles in policy interest rates in 24 advanced economies over 1970-2024, combining a new application of business cycle methodology with rich time-series decompositions of the shocks driving rate movements. "Rate cycles" have gradually evolved over time, with less frequent cyclical...

We examine how the occurrence of natural disasters impact the US economy and financial markets using monthly data since 2000. Our analysis reveals large sustained adverse effects of disasters on overall economic activity, with significant implications across various sectors including labor,...
