The aim of this paper is to present an analysis whether certain financial ratios can have a significant impact on the development of a stock exchange index. In particular the benchmark stock exchange index is considered, as well as, the selected ratios are considered as the average ones for the whole economy. Quarterly data between 2005 and 2015 were analyzed for the Warsaw Stock Exchange (Poland).

A modern market economy is an exceedingly complex, infinite-dimensional, stochastic dynamical system. The failure of mainstream economists to characterize its dynamics may well be due to its intractability. This paper argues that the characterization of its dynamics becomes almost trivial when it is analyzed from the perspective of infor-mation production. Whether its Jacobian matrix is specifiable or not, a Lyapunov spectrum can be constructed from which the potential Kolmogorov-Sinai or Shannon entropy can be assessed. However, a self-organized equilibrium must first obtain, and for that a suitable policy must be operational.

It is important to determine the dominant fiscal regime in a country group for policy prevision. This paper examines whether the Ricardian fiscal regime or non-Ricardian fiscal regime is dominant in the Common Wealth of Independent States (CIS). We attempted to show that CIS' behavior after the debt stock increase. Using panel data method, this paper finds that Ricardian regime dominates in Kyrgyz Republic, Russian Federation, Tajikistan, Uzbekistan, Moldova and Turkmenistan's fiscal policies.

If the demand under price dispersion is formed by consumers with zero search costs and consumers with positive search costs, the law of one price holds at the equilibrium price level, where the lowest willingness to pay between consumers with zero search costs meets the willingness to accept or to sell of consumers with positive search costs. Consumers with positive search costs maximize their utility with respect to their optimal decisions when marginal losses in labor income during the search are equal to marginal savings on purchase. Optimal decisions move their willingness to accept to the equilibrium price level. Suboptimal decisions of consumers with positive search costs result in willingness to accept below the lowest willingness to pay of consumers with zero search costs and arbitrage takes place. Arbitrage drops down the equilibrium price to the level where willingness to accept of consumers with positive search costs meets the new lowest willingness to pay of consumers with zero search costs and where purchasing decisions of consumers with positive search costs become optimal.
