Motivating people to contribute knowledge has become an important research topic and a major challenge for organizations in the Knowledge Economy. In order to promote knowledge-sharing, managers need to understand the mechanism that drives individuals to contribute their valuable knowledge. Several theories have been applied to study the knowledge-sharing behavior, including social exchange, so...

This paper endeavored to categorise and evaluate exchange rate theories. These theories included the International Fischer's Effect Theory, Purchasing Power Parity Interest Rate Balance of Payments Monetary Approach Foreign Exchange, Portfolio Approach. The analyses these theories' advantages disadvantages. Keywords: Exchange Rate; Theory; Approach; DOI: 10.7176/EJBM/14-20-08 Publication date: ...

The gauge theory of arbitrage was introduced by Ilinski in [1] and applied to fast money flows in [2,3]. The theory of fast money flow dynamics attempts to model the evolution of currency exchange rates and stock prices on short, e.g. intra-day, time scales. It has been used to explain some of the heuristic trading rules, known as technical analysis, that are used by professional traders in the...

We introduce game theory as a formal framework in which exchange protocols can be modeled and their properties can be studied. We use this framework to give a formal deenition for rational exchange relating it to the concept of Nash equilibrium in games. In addition, we study the relationship between rational exchange and fair exchange. We prove that fair exchange implies rational exchange, but...

Considering the implications of social exchange theory as a context for social role behavior, we tested relations between ethical leadership and both person- and task-focused organizational citizenship behavior and examined the roles played by employee gender and politics perceptions. Although social exchange theory predicts that ethical leadership is positively associated with citizenship, soc...

In this century, the main concerns of theoretical chemistry obviously make the transition from accurate investigations of small molecules to the designs of complicated large molecular systems; e.g. proteins, nano-materials, environmental catalyses, and so forth. What is necessary for approaching these systems is an accurate theory of low computational order. Density Functional Theory (DFT),, is...
