This paper assesses time variation in monetary policy rules by applying a Time-Varying Parameter Generalised Methods of Moments (TVP-GMM) framework. Using monthly data until December 2022 for five inflation targeting countries (the UK, Canada, Australia, New Zealand, Sweden) and five countries...

Recent empirical evidence shows that most international prices are sticky in dollars. This paper studies the optimal policy implications of this fact in the context of an open economy model, allowing for an arbitrary structure of asset markets, general preferences and technologies, time-or...

For the academic audience, this paper presents the outcome of a well-identified, large change in the monetary policy rule from the lens of a standard New Keynesian model and asks whether the model properly captures the effects. For policymakers, it presents a cautionary tale of the dismal...

In the revised monetary policy strategy of the European Central Bank (ECB), “price stability is best maintained by aiming for two per cent inflation over the medium term”, with “symmetric commitment” to this target. “Symmetry means that the Governing Council considers negative and...

Central bank independence (CBI) is a very important precondition for price stability. However, the empirical evidence for a correlation between both is relatively weak. In this paper, this weakness is countered with a) an extended measure of monetary commitment, which includes well-known...

This paper, using a microfounded macroeconomic model that embeds the key features of the Greek economy, studies the efficacy of the various policy measures taken, at national and EU level, to cushion the economic effects of the pandemic shock. The paper attempts to give quantitative answers to...

We study a fiscal policy model in which the government is present-biased, leading to an excessive public deficit. An optimally designed fiscal rule needs to trade off the benefit of committing the government to not overspend against the benefit of granting it flexibility to react to shocks to...

We document a new stylized fact for the life-cycle behavior of consumer prices: relative to a narrowly defined set of competing products, the price of individual products tends to fall over the product lifetime. This holds true for more than 90% of the expenditure items underlying the U.K....

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...
