While the impact of exchange rate changes on economic growth has long been an issue of key importance in international macroeconomics, it has received renewed attention in recent years, owing to weaker growth rates and the debate on currency wars. However, in spite of its prevalence in the...

DSGE models with generalized shock processes have been a major area of research in recent years. In this paper, I show that the structural parameters governing DSGE models are not identified when the driving process behind the model follows an unrestricted VAR. This finding implies that...

This paper shows how exact solutions for the transient density of a large class of continuous-time Markov switching models can be obtained. We illustrate the pertinent approach for both simple diffusion models with a small number of regimes as well as for the more complicated so-called Poisson...

The extensive margin of bilateral trade exhibits a high level of persistence that cannot be explained by geography or trade policy. We combine a heterogeneous firms model of international trade with bounded productivity with features from the firm dynamics literature to derive expressions for an...

Long memory (long-term dependence) of volatility counts as one of the ubiquitous stylized facts of financial data. Inspired by the long memory property, multifractal processes have recently been introduced as a new tool for modeling financial time series. In this paper, we propose a parsimonious...

Maximum likelihood estimation of discretely observed diffusion processes is mostly hampered by the lack of a closed form solution of the transient density. It has recently been argued that a most generic remedy to this problem is the numerical solution of the pertinent Fokker-Planck (FP) or...

Available evidence supports the view that growth is faster in more open economies. In order to analyze the implications of openness and growth on determinacy and learnability of worldwide rational expectations equilibria we develop a two-country New Keynesian model with growth. We analyze these...

Although the ERM II rules allow the Danish krone to fluctuate against the euro within an official target zone of 4.5%, most of the time the exchange rate has remained in a narrow range around its unconditional mean. Estimating a Smooth Transition Autoregression Target Zone (STARTZ) model...

Ukrainian exports can be explained by standard demand theory in the long run. Using the Johansen procedure the data do not reject the hypothesis of a unit foreign-production elasticity of Ukrainian exports, which are rather price-elastic inputs for foreign producers. It is argued that due to...

We examine the effect of exchange-rate misalignments on competition in the market for large commercial aircraft. This market is a duopoly where players compete in dollar-denominated prices while one of them, Airbus, incurs costs mostly in euros. We construct and calibrate a simulation model to...
