The Efficient Markets Hypothesis provides a theoretical basis for trading rules. Technical trading rules provide a signal of when to buy or sell an asset based on such price patterns to the user. Technical traders tend to put little faith in strict efficient markets. Fundamentalists rely on...

An economic model of cycles focused on the foreign capital investment phenomenon will be briefly introduced. We consider a system of the first order non-linear differential equations where a feedbackfunction is controlled by a capital/output ratio parameter. The value of potential gross domestic...

Macroeconomic models usually represent an equilibrium unemployment rate by using a differential equation. The solution of the differential equation expresses the natural unemployment rate. The same result is possible to achieve by using an introduced Markov's model of unemployment. Markov's...

Ekonomická dynamika je systematické studium ekonomických změn. Analyzují se změny ve výrobě, ve spotřebě, v obchodu, v alokaci zdrojů, v chování cen a v bohatství společnosti. Její součástí jsou dynamická teorie trhů, zabývající se chováním nabídky a poptávky a...

In this contribution we illustrate some applications of the theory of dynamical systems with parameteric and interval uncertainties to the analysis of limiting behaviour and stability of some neokeynesian macroeconomic models considered in [6]. The analysis is based on linearization of the...

In this contribution we illustrate some applications oť the theory oť linear systems with interval uncertainties to the stability and speed oť adjustment analysis oť some macroeconomic models. In particular, we ťocus our attention on the Keynes and neoclassical systems, as well as on the...

We have shown that in the period of 1995-1997 the weak form Efficient Market Hypothesis does not apply to the Prague Stock Exchange. This conclusion is supported especially by the magnitude of autocorrelation between subsequent returns. Due to this result, the confirmation and analysis of...

The non-linear approach to economic dynamics enables us to study traditional economic models using modified formulations and different methods of solution. In this article we compare dynamical properties of Keynesian and Classical macroeconomic models. We start with an extended dynamical IS-LM...

The Van der Pol's equation (VdPe) with an appropriate feedback is applied on construction of a model of economic cycles. The model exhibits the ability of the savings and investments to give output in a limit cycle by bifurcation. According to the life cycle hypothesis, the households will have...
