The aim of this article is to demonstrate how the change in actual and potential market risks in the Dow Jones Industrial Average (DJIA) during the 2-year period 2007 to 2008 can be analysed with the help of (<italic>λ</italic>, <italic>σ</italic> -super-2)-analysis. In the empirical analysis, the average of the Lyapunov...

ABSTRACT We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporaneous data on the variables in the rule, the central bank can disregard from the exchange rate as long as...

It is shown in this letter that the magnitude of exchange rate overshooting is larger than in Dornbusch (1976) when chartists are introduced into the model. Specifically, the extent of overshooting depends inversely on the planning horizon. The latter follows from explicitly modelling the...

"It is demonstrated that adaptive learning in the least squares sense may be incapable of satisfactorily reducing the number of attainable equilibria in a rational expectations model when focusing on the forward-solutions to the model. The model examined, as an illustration, is a basic asset...

We embed different instrument rules into Gal?and Monacelli's new Keynesian model for a small open economy that is augmented with technical trading in currency trade to examine the prerequisites for monetary policy. Specifically, conditions for a determinate and least squares learnable REE are in...

Can nominal exchange rates be characterized by deterministic chaos? To answer this question, a statistical framework utilizing a blockwise bootstrap procedure is used to test for the presence of a positive Lyapunov exponent in an observed stochastic time series (Bask and Gencay, 1998). Daily...

We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporaneous data on the variables in the rule, the central bank can disregard from the exchange rate as long as there is...

We examine if the Nordic power market, Nord Pool, has been competitive or if electricity suppliers have had market power. Specifically, since the evolution from national markets to a multi-national and largely deregulated power market has taken place stepwise, we also examine how the degree of...

The first aim of this paper is to clarify the differences and relationships between cumulative advantage/disadvantage and the Matthew effect. Its second aim, which is also its main contribution, is not only to present a new measure of the Matthew effect, but also to show how to estimate this...
