Our paper presents a set of stylized empirical facts resulted from the statistical investigation of the daily and monthly price variations of European stock market indices during the period April 2007 - March 2012. We study 21 regional and global stock market indices calculated by MSCI Barra,...

In this preliminary research, we tried to statistically analyze the facts and to clarify the reality of the subsidy system (direct and indirect) in Tunisia, based on data, meticulously collected via many sources, covering the period from 2000 to 2012. The stylized facts shows that the overall...

Background: Since the attribution of the Nobel prize in 2002 to Kahneman for prospect theory, behavioral finance has become an increasingly important subfield of finance. However the main parts of behavioral finance, prospect theory included, understand financial markets through individual...

We study the probability distribution of stock returns at mesoscopic time lags (return horizons) ranging from about an hour to about a month. While at shorter microscopic time lags the distribution has power-law tails, for mesoscopic times the bulk of the distribution (more than 99% of the...

In this paper, we investigate the properties of the return time series generated by a multi-agent-based model for financial markets. Our model is a variant of the grand canonical minority game model where the agents behave as producers and a fraction of them is allowed to shift their strategy in...

We present a behavioral stock market model in which traders are driven by greed and fear. In general, the agents optimistically believe in rising markets and thus buy stocks. But if stock prices change too abruptly, they panic and sell stocks. Our model mimics some stylized facts of stock market...

We show that the current economic crisis has led the market to exhibit a non-critical behavior. We do so by analyzing the quantitative parameters of time series from the main assets of the Brazilian Stock Market BOVESPA. By monitoring global persistence we show a deviation of power law behavior...

We propose a new set of stylized facts quantifying the structure of financial markets. The key idea is to study the combined structure of both investment strategies and prices in order to open a qualitatively new level of understanding of financial and economic markets. We study the detailed...

One of the most important objectives of the macroeconomic science is the comprehension of causes and consequences over the economic fluctuations. The statistical characterization of business cycles has been studied by many authors since the influential work by Hodrick and Prescott (1980)....

Statistics are developed to test for the presence of an asymptotic discontinuity (or infinite density or peakedness) in a probability density at the median. The approach makes use of work by Knight (1998) on L1 estimation asymptotics in conjunction with non-parametric kernel density estimation...
