02. INNOVATION AS EVOLUTIONARY PROCESSES
A new paper has been published and available online in BFI website.
This paper extended the memetic model of innovation presented
previously on Khanafiah and Situngkir (2004). In this paper authors
propose agent-based model of innovation of technological artifact using
memetic approach. The paper performs the simulation to analyze the
dynamic of fitness value of each artifact in the population of agents.
The result of simulation shows that the attribution of agent and
interaction among them are playing the important role in dynamic of
fitness of artifact. The results of simulation also showed us that
innovation of technological artifact is the complex phenomena where
their dynamic emerges from the complex interactions social agents. The
paper is written by Deni Khanafiah and Hokky Situngkir and available
for free download in: http://www.bandungfe.net/?go=xpe&&crp=44ce467f
03. RANDOM MATRIX THEORY & INDONESIAN STOCK MARKET
Another paper on econophysics shows how the random matrix theory is
used to focus on the behavior of eigen vector when the eigen value is
outside the boundaries of the random matrix in different time interval
and data density. The results show the appropriateness of the eigen
value and vector eigen in the terms of statistical distribution. The
projection of eigen vector to the IHSG (Indonesian composite index)
shows the high appropriateness of largest eigen value and this
appropriateness decreased drastically in the second largest eigen value
although still beyond the random matrix upper boundaries. By
calculating the Inverse Participation Ration (IPR) the authors found
that more than a half of the stocks contribute to compose the largest
eigen value. Interestingly, the paper also shows how the LQ-45 index
(index of the 45 most liquid stocks in Jakarta Stock Exchange)
dominates in this highest eigen value. The report is written by Yun
Hariadi and Yohanes Surya and available for download (Indonesian) in:
