The difference between market risk and potential market risk is emphasized and a measure of the latter risk is proposed. Specifically, it is argued that the spectrum of smooth Lyapunov exponents can be utilized in what we call (l, s2)-analysis, which is a method to monitor the aforementioned...

It is demonstrated in this paper that adaptive learning in least squares sense may be incapable to reduce, in a satisfactory way, the number of attainable equilibria in a rational expectations model. The model inves-tigated, as an illustration, is the monetary approach to exchange rate...

We embed different instrument rules into a 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, this paper focuses on conditions for a determinate, least-squares learnable rational...

The aim of this letter is to discuss and illustrate what we call (lambda, sigma-2)analysis, which is a method to distinguish between the stability of a stochastic dynamic system and the volatility of a variable generated by this system. It is also emphasized that this method is able to generate...

By using a novel approach in this paper,(lambda,sigma²)-analysis, we have found that electricity prices most of the time have increased in stability and decreased in volatility when the Nordic power market has expanded and the degree of competition has increased. That electricity prices at Nord...

non-linear dynamic models may be characterized and studied, where the degree of stability is defined by the effects of exogenous shocks on the evolution of the observed stochastic system. This type of stability concept is frequently of interest in economics, e.g., in real business cycle theory....

We propose an extension of the often used rational addiction model. Our model includes both legal and illegal cigarettes. The model is tested on a Swedish data set covering the aggregate legal and illegal cigarette markets. When we treat legal and illegal cigarettes as independent demand...

This thesis consists of four papers. The first three deal with deterministic chaos in exchange rate series whereas the fourth deals with technical analysis in the foreign exchange market. Paper [i] (

How has the European monetary integration, with the creation of the EMU, affected the stability and volatility of foreign exchange? In order to answer this question, stability and volatility measures are defined and calculated. We then use these to investigate the changes in the stability and...

It is well-known that cigarette smoking and the use of other addictive goods is harmful to health. Still, some people smoke cigarettes and drink alcohol in their daily life. The consumption of addictive goods seems, therefore, to be the anti-thesis of rational behavior. In this paper, however,...
