Title: Fuzzy logic and behavioral finance : an approach using fuzzy c-means algorithm Authors: Aparecido Aguiar, Renato Abstract: The aim of this paper is to show the connection between the behavioral finance theory and fuzzy sets theory. Such connection, little explored by researchers, may produce new models for the financial market, leading to a better understanding of anomalies not explained by modern theory of finance. In this paper two techniques based on fuzzy sets, an clustering algorithm and the fuzzy transform shown incorporate, intrinsically, the heuristics of representativeness and anchoring of the behavioral finance theory

Title: Momentum and reversals : an alternative explanation by non-conserved quantities Authors: Appel, Dominik; Dziergwa, Katrin; Grabinski, Michael Abstract: The momentum effect in stock trading means that stocks performing well in the past will do so in the future, too. A recent (seemingly) proof of it would be a big discovery: Stock prices would obey laws similar to the Newtonian equation of motion. However, using the recent result that stock prices are distinct from stock values, the whole mystery disappears without a trace. Stock prices fluctuate chaotically (in a mathematical sense). Therefore the momentum within stock prices is easily explained by a self-fulfilling prophecy as long as enough people believe in it. In the recent experimental "proof" of the momentum effect, stocks had been traded thousands of times. In generalizing the well-known average cost effect, we give a second quantitative explanation for the observed results.

Title: Dependence structure of equity and foreign exchange markets : evidence from industrialized Asian economies Authors: Luo, Robin H.; Anh Nguyen, Thi Kim Abstract: The world economy has experienced a number of financial crises over the past 15 years. They placed significant impacts on various countries. This paper attempts to explain the reasons causing the comovement of foreign exchange market with the stock market in the industrialized Asian economies, including Japan, Korea, and Singapore. We find that the relationship is stronger during the crisis period. Johansen cointegration test result also supports the strong linkage in trading activities between industrialized Asian economies and U.S..

Title: Minimax theorem and Nash equilibrium Authors: Ferreira, Manuel Alberto M.; Andrade, Marina; Peixoto Matos, Maria Cristina; Filipe, José António; Pacheco Coelho, Manuel Abstract: Two important results in Economics, the Minimax Theorem and the Nash Equilibrium are presented together with their mathematical fundaments. The results are obtained in the field of Functional Analysis.
