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...

Inflation targeting is implemented in different ways – most often by adopting point targets, by having tolerance bands around a point target, or by specifying target ranges. Using data for 20 economies, this paper tests whether the various target types affect the anchoring of inflation...

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...

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...

This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

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....

Given buoyant capital inflows and managed exchange rates the majority of emerging market central banks have continued to accumulate massive foreign reserves. If left unsterilized, the liquidity expansion can threaten domestic macroeconomic stability. To contain domestic inflation these central...

This study tests FDI technology spillover models with the assumption that learning takes time against wage bargaining models by estimating the wage-premium of a foreign takeover. The technology spillover theory predicts a larger wage growth in firms taken over by foreign investors than in local...
