An estimated Markov-switching DSGE modelling framework that allows for parameter shifts across regimes is employed to test the hypothesis of regime-dependent credibility of Hong Kong s linked exchange rate system. The model distinguishes two regimes with respect to the time-series properties of...

This paper explores the Balassa-Samuelson effect in a New-Keynesian DSGE model of a monetary union with traded and non-traded goods. Credible sets for theoretical impulse response functions show that a model with perfect intersectoral labour mobility is unable to reproduce an appreciation of the...

We represent the dynamic relation among variables in vector autoregressive (VAR) models as directed graphs. Based on these graphs, we identify so-called strongly connected components (SCCs). Using this graphical representation, we consider the problem of variable selection. We use the relations...

The New Keynesian DSGE literature has come to the consensus that, from the perspective of business cycle stabilization, countries are worse off in terms of welfare by forming a monetary union. This consensus, however, is based on the assumption of monetary policy being optimal. Using a standard...

As a consequence of asset purchases by the European Central Bank (ECB), longer- term yields in the euro area decline, and spreads between euro area long-term yields narrow. To assess spillovers of these recent financial developments, we use a Bayesian variant of the global vector autoregressive...

This paper introduces a new effective exchange rate regime classification. Traditional classifications define the stability or flexibility of a currency with respect to one ("anchor") currency, thus implicitly neglecting information on exchange rate relationships against other currencies. Our...

The desirability of flexible exchange rates is a central tenet in international macroeconomics. We show that, with forward-looking staggered pricing, this result crucially depends on the monetary authority's ability to commit. Under full commitment, flexible exchange rates generally dominate a...

Using a data-driven approach to identify structural vector autoregressive models, we examine key factors influencing the US dollar exchange rate across eight advanced economies from 1980 to 2022. We find that shocks to inflation expectations, which are closely tied to unfunded government...
