Parallel calculations on modern multiprocessing technics open new opportunities in application of mathematical models for research ekonomy of region. Use of normative models was limited to complexity of their identification due to a lot of unknown parameters. In work the technique of...

A simplest multi-sector dynamic model for regional economy is a normative balance mathematical model, but it contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. Only confidence intervals for the unknown parameters can be computed from the...

Article on the use of system analysis methodology for modeling socio-economic processes. The author justifies the methodological approach, based on dynamic analysis of exogenous processes in economic and social management practices. Particular attention is paid to the use of index indicators...

This paper investigates possible spill over effects on the Spot Market due to the initiation of Futures contracts in three different financial markets. According to many analysts there still exists a puzzle regarding the stabilization or destabilization effects of futures contracts. Although the...

Market price dynamics for North American oriented strand board markets are examined. Specifically, the role of transactions costs are examined vis–`a–vis the law of one price. Weekly data for the January 3rd, 1995 through April 14th, 2006 period are used in the analysis. Nonlinearities...

One of the most important instruments of economic policy of the opened countries is the exchange rate. It is considered both a mean of monetary regulation and a tool of outside competitiveness. Morocco plans to adopt the floating exchange rate regime, in the end of 2009. Indeed, the question...

In this paper, we try to build an efficient portfolio among four possible portfolios based on the some 31 Casablanca listed shares. Our analysis concerns the risk which arises from the Markowitz mean-variance approach. Our work method will be implemented as following: first of all, we will test...

We apply a recently proposed Bayesian model selection technique, known as stochastic model specification search, for characterising the nature of the trend in macroeconomic time series. We illustrate that the methodology can be quite successfully applied to discriminate between stochastic and...

We build a small-scale factor model for the GDP of one of the hardest hit economies during the latest recession to study the exact dynamic versus static factor model performance along a business cycle, with an emphasis placing on nowcasting performance during a pronounced switch of business...

The paper compares one-period ahead forecasting performance of linear vector-autoregressive (VAR) models and single-equation Markov-switching (MS) models for two cases: when leading information is available and when it is not. The results show that single-equation MS models tend to perform...
