In general, risk of an extreme outcome in financial markets can be expressed as a function of the tail copula of a high-dimensional vector after standardizing marginals. Hence it is of importance to model and estimate tail copulas. Even for moderate dimension, nonparametrically estimating a tail...

The collapse of former communist regime in Central and Eastern Europe opened the transition period from centrally planned to market oriented economies. Thus, the exploration of economic systems in the special situation of transition has become an interesting research topic. The exposition plan...

By looking closely at the underlying structural causes of the discontinuity that appeared in the behavior of the U.S. stock market at 2:40pm in the afternoon of 6th May 2010. What transpired in those 7 minutes is viewed best as a hitherto unrecognized “emergent property” of structural...

The new business cycle three-dimensional model is formulated on the basis of new system approach known as the System Potential Method. Cyclical dynamics with catastrophe jumps (alike to Varian' model) and some stochastic properties is described. Properties of such cycles are similar to the...

It is proposed to consider the business cycle as hysteresis loop with fluctuating limiting points. Concept is based on the Method of System Potential, (Proceedings of International System Dynamics Conference 2003, No.56) which describes dynamics of spontaniously arising Complex Systems as the...

The new business cycle three-dimensional model is formulated on the basis of new system approach known as the Method of Systems Potential. Cyclical dynamics with catastrophe jumps (alike to N.Kaldor (1940) model) and some stochastic properties is described. Properties of such cycles are similar...

Structural changes were the main focus of many studies in recent years. Changes which alter the socio-economic status of a nation from deprived and traditional nature to a developed and modern one. The main hypothesis of this study is that, the economic development does not occur through a...

Empirical data show during the historical process of economic development profound structural changes in economy. One of the most important movements is from stages where the so-called tangible investments are predominant to those where intangible investments become predominant. Applying some...

When running agent-based simulations using ready-made components, one usually faces heterogenity problems both for the agents implementation and for the underlying platform. To circumvent these kind of hindrances, we introduce a wrapper technique for mapping the functionality of agents living in...
