In their path-finding 1973 paper Black and Scholes presented two separate derivations of their famous option pricing partial differential equation (pde). The second derivation was from the standpoint that was Black’s original motivation, namely, the capital asset pricing model (CAPM). We show...

We provide an analytical approach that facilitates understanding the bifurcation mechanism of a wide class of economic models involving spatial agglomeration of economic activities. The proposed method overcomes the limitations of the Turing (1952) approach that has been used to analyze the...

This paper approaches the problem of knowledge accumulation by the management team of organizations, but specially that ones focused on obtaining profit in order to obtain competitive advantage. After a brief presentation of the general context, the idea of continuing learning as investment is...

The paper discusses opportunities to utilize the series of micro-blogs as provided by the Twitter in observation of opinion dynamics. The spontaneity of tweets is more, as the service is attached more to the mobile communications. The extraction of information in the series of tweets is...

Is it better to apply effort to increase personal consumption, or control what one wants? The model presented here provides a characterization of demand for self control, namely, its responsiveness to price and risk. Unlike most other models of self control, the model does not identify self...

A Really GENERAL Decomposition Algorithm for Very Large Linear Optimization Problems Proven theory as Regards Optimality and Finality Advantageous for very large problems with a rather small percentage of real variables in the optimal solution - Simplex method is used as a calculating...

We propose a numerical procedure for the pricing of financial contracts whose contingent claims are exposed to two sources of risk: the stock price and the short interest rate. More precisely, in our pricing framework we assume that the stock price dynamics is described by the Cox, Ross...

The paper discusses the utilization of social complexity studies to enhance our understanding on many social phenomena. The discussions brings the concept of uncertainty in almost everything of social realms and makes some points related to the empirical findings of the power-law distributions...

So far little effort has been put into researching the importance of internal ERP project stakeholders’ mutual interactions, realizing the project’s complexity, influence on the whole organization, and high risk for a useful final outcome. This research analyzes the stakeholders’...
