MODELING OF CROSS-BORDER SPREADING OF FINANCIAL CRISIS

Abstract

The article deals with the features of the crisis propagation through financial and trade channels. The basic premises that should be taken into account when modeling them are given. In particular, to describe the temporal structure of these processes, the author introduces the term «latent period» and substantiates an algorithm for determining its time boundaries. A quantitative assessment of the proposed concept efficiency was carried out. Based on the results obtained, a selection of macroeconomic indicators was carried out which characterize the main channels for the spread of crisis phenomena and describe the deformation processes well in advance of the end of the latent period. As a result of analysis and testing, a system of input classification characteristics is formed, which are necessary to build an economic and mathematical model for predicting the effects of the financial crisis spreading: total reserves excluding gold; the ratio of the M2 monetary aggregate to the total reserves; money multiplier; change in the monetary aggregate M0; change in the monetary aggregate M2; spread of interest rates on loans in foreign currency within the country to the same indicator abroad; monetization coefficient; export growth; import growth; export share in GDP. The obtained neural network-classifier divides the space of the starting points (each of which has a spatial dimension of ten coordinates and is characterized by a time depth in the latency period for the country under study) into clusters, within which the dynamics of such indicators as GDP, national currency per SDR, total reserves excluding gold, publicly guaranteed debt and the value of external government loan bonds are similar. This allowed us to form a base of scenarios of the possible behavior of economies under the influence of the processes of the spread of crisis phenomena based on macro indicators characterizing the state of the financial and trade spreading channels.
