We have studied statistical characteristics of five share price time series. For each stock price, we estimated a best fit quantitative model for the monthly closing price as based on the decomposition into two defining consumer price indices selected from a large set of CPIs. It was found that...

Share prices of financial companies from the S&P 500 list have been modeled by a linear function of consumer price indices in the USA. The Johansen and Engle-Granger tests for cointegration both demonstrated the presence of an equilibrium long-term relation between observed and predicted time...

Previously, we have revealed the presence of a reliable linear dependence between share prices of energy-related companies and the difference between CPI and core CPI: any change in share prices is transmitted into a proportional change in this difference two and half months later. The...

Abstract: Economic studies on migration of skilled labor are mainly related to those trained in the country of origin but are increasingly including students trained abroad that return or not to their home countries. There are incentives and constraints that are provided by both origin and...

The scientific practice, in the several social sciences, cannot be implemented without the researcher clearly defines in depth the theoretical and meta-theoretical foundations that underpinning the research. Similarly, the unambiguous understanding of the concepts, in view of the...

This paper considers the pros and cons of establishing stock markets in Sub-Saharan African economies at the present stage of their development. It provides theoretical analysis and empirical evidence from both developing and advanced countries to argue that for many African countries such a...

Conceptual overview, critical commentary and future directions

In diesem Beitrag zeigen wir, dass theoretische und technologische Aussagensysteme zwei eigenständige Forschungszweige darstellen und damit die Notwendigkeit erwächst, eine eigene Methodologie technologischer Aussagensysteme zu entwerfen. Wir stellen erste Ansatzpunkte vor, wie eine solche...
