The Moment

In many cases, it is difficult to find a solution to a system of difference equations with random structure in a closed form. Thus, a random process, which is the solution to such a system, can be described in another way, for example, by its moments. In this paper, we consider systems of linear difference equations whose coefficients depend on a random Markov or semi-Markov chain with jumps. The moment equations are derived for such a system when the random structure is determined by a Markov chain with jumps. As an example, three processes: Threats to security in cyberspace, radiocarbon dating, and stability of the foreign currency exchange market are modelled by systems of difference equations with random parameters that depend on a semi-Markov or Markov process. The moment equations are used to obtain the conditions under which the processes are stable.

The article is devoted to the study of currency risk hedging in international business. The article notes that the international foreign exchange market is the largest and fastest growing of all world markets. The characteristic features of the international currency market are substantiated and offered. It is also noted that foreign exchange transactions provide economic ties between participants located on different sides of state borders: settlements between firms from different countries for the supply of goods and services, foreign investment, international tourism and business travel. It is determined that hedging of currency risks is the protection of funds from the unfavorable movement of exchange rates, and is carried out in fixing the current value of funds by concluding an agreement on the foreign exchange market. When hedging, the risk of exchange rate changes disappears, and this makes it possible to forecast the company's activities and see the financial result, which is not distorted by exchange rate fluctuations, which will allow you to determine product prices, calculate profits, etc. The main difference between hedging and other types of transactions is that its purpose is not to generate additional profits, but to reduce the risk of potential losses, as risk reduction is almost always necessary to pay, hedging, of course, involves additional costs. Hedging is a way to improve business planning. An enterprise wishing to use this service shall pledge the specified amount, from which losses on its positions will be deducted. In today's conditions, thanks to the foreign exchange market, there is a very reliable way to hedge currency risk. This method is to fix the current value of funds by concluding agreements in this market. With hedging, the company eliminates the risk of exchange rate fluctuations, and this allows you to forecast activities and see the financial result, which is not changed by exchange rate fluctuations. Allows you to pre-determine product prices, determine profits, etc. Thus, the principle of hedging in international business is to open a currency position in a foreign currency account for future transactions to convert funds.

The risk of contagion is the possibility that the failure of a financial institution affected by an exogenous shock generates the failure of other institutions not initially affected by the shock. As pointed out by Upper and Worms (2002) and others, the domino effect in the payment system depends on the precise pattern of interbank linkages. This paper studies the occurrence of financial contagion after the exogenous failure of an institution authorized to operate in the Brazilian interbank currency market. The data contain information about all the actual transactions that occurred in this market from August 1st, 2000 to October 31st, 2002. The adopted methodology shows the occurrence of contagion propagation in several subsequent rounds after the initial failure. We quantify the number of institutions that breakdown and the financial losses of the market. There is a large increase in the number of failed institutions during the period of the presidential elections in 2002.

Currency Exchange

In today’s global market economy, currency exchange rates play a vital role in national economy of the trading nations. In this chapter, we present an overview of neural network-based forecasting models for foreign currency exchange (forex) rates. To demonstrate the suitability of neural network in forex forecasting, a case study on the forex rates of six different currencies against the Australian dollar is presented. We used three different learning algorithms in this case study, and a comparison based on several performance metrics and trading profitability is provided. Future research direction for enhancement of neural network models is also discussed.

In this paper, we are going to introduce a new Islamic financial institution with elaborated economic and financial characteristics. «Non-Usury Bank Corporation» (NUBankCo) is defined in a way that depositors are the shareholders of the Bank. This corporation is a new kind of shared ownership corporation which its shareholders are deposit holders and their deposits work as corporation’s equities. The defined bank can perform non-usury operations, and by designing a behavioral model, it is shown that NUBankCo can draw an environment that the welfare of society is to be maximized. Mobility of deposit resources in NUBankCo is less than conventional banks, and there are fewer conflicts between large and small shareholders/depositors and limits the emergence of shareholders’ cartels and thus huge sudden outflow of funds which creates bankruptcy crises.OECD’s corporate governance criteria are completely adaptable to this bank. Other pronouncements like Basel, AAOFI, IFSB, and FSF can be applied to this bank. NUBankCo can be established in different countries and can be adapted to different monetary, banking, foreign exchange, and commercial laws and regulations and can coexist in competition with conventional banks.NUbankCo will be Islamic in deposit mobilization side and will be Islamic in the loan/credit side for certain Islamic contracts and banking operations. Foreign currency exchange operations, bonds, commercial papers, and precious metals transactions, cash and draft operations, and credit and beneloan (non-interest loan) operations are characterized for NUBankCo to be fully Islamic.
