A purpose of this paper is to formulate a continuous dynamical model for a small closed economy with a simple structure and with a minimum number of non-linearities. A basis of this model is developed from dynamical Kaldorian model. Variables in the modified dynamical Kaldorian model are in a...

We show that the cusp catastrophe model explains the crash of stock exchanges much better than other models. On the data of U.S. stock markets we demonstrate that the crash of 1987 may be better explained by cusp catastrophe theory, which is not true for the crash of 2001. With the help of...

In this paper, we introduce a new measure of capital market efficiency. For its construction, we use the approaches of fractal dimension, Hurst exponent and entropy. The method is applied on 41 stock indices from the beginning of 2000 till the end of August 2011 and interesting results are found...
