Analyzing the Spectrum of Asset Returns: Jump and Volatility Components in High Frequency Data
Analyzing the Spectrum Asset Returns Jump Volatility Components High Frequency Data
2014/3/13
This paper reports some of the recent developments in the econometric analysis of semimartingales estimated using high frequency financial returns. It describes a simple yet powerful methodology to de...
Benford's law and Theil transform of financial data
income expenses religious community Benford's laws Theil map time series.
2012/9/14
Among econophysics investigations, studies of religious groups have been of interest. On one hand, the present paper concerns the Antoinist community nancial reports, - a community which appeared at ...
An algorithm for the orthogonal decomposition of financial return data
portfolio selection mean-variance analysis principal components of risk
2012/9/14
We present an algorithm for the decomposition of periodic financial return data into orthogonal factors of expected return and “systemic”, “productive”, and “nonproductive”risk. Generally, when the nu...
On the scaling ranges of detrended fluctuation analysis for long-memory correlated short series of data
scaling range detrended fluctuation analysis Hurst exponent power laws time series long memory econophysics complex systems
2012/9/14
We examine the scaling regime for the detrended fluctuation analysis (DFA) -the most popular method used to detect the presence of long memory in data and
the fractal structure of time series. First,...
A multivariate piecing-together approach with an application to operational loss data
copula domain of multivariate attraction GPD copula multivariate extreme value distribution multivariate generalized Pareto distribution
2012/6/5
The univariate piecing-together approach (PT) fits a univariate generalized Pareto distribution (GPD) to the upper tail of a given distribution function in a continuous manner. We propose a multivaria...
Study on Stock Index Futures’ Mean Reversion Effect and Arbitrage in China Based on High-Frequency Data
CSI 300 Index Future High-Frequency Data Futures-Spot Arbitrage Mean Reversion Effect Mispricing Ratio
2013/2/23
Based on 1 minute high frequency data, this paper constructs no-arbitrage band for CSI300 index futures, and empirically studies the futures-spot arbitrage. Furthermore, the mean reversion and its tim...
We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy follows indeed the concept of creative destruction, as proposed by J.A. Schump...
Data envelopment analysis with classification and regression tree – a case of banking efficiency
banking efficiency bootstrapping classification and regression data envelopment analysis
2011/9/26
Data envelopment analysis (DEA) is a non-parametric method for measuring the efficiency and productivity of decision-making units (DMUs). On the other hand data mining techniques allow DMUs to explore...

2011/9/19
Current decision-making in natural resource use and management aims at delivering ecologically-sustainable development to achieve conservation and economic benefits. The process of guiding natural res...
Venture Capital Availability and Labor Market Performance in Industrial Countries: Evidence Based on Survey Data
employment rates venture capital business executives
2011/9/11
This paper finds that more readily available venture capital is likely to have lowered unemployment rates and raised employment rates in industrial countries over the period 1982 to 2003. More readily...
Has U.S. Monetary Policy Changed? Evidence from Drifting Coefficients and Real-Time Data
forward-looking Taylor rule Greenbook Parameter instability time-varying parameter model
2011/8/21
Despite the large amount of empirical research on monetary policy rules, there is surprisingly little consensus on the nature or even the existence of changes in the conduct of U.S. monetary policy. T...

Nonparametric Estimation Of Varying Coefficient Dynamic Panel Data Models
semiparametric dynamic NPGMM consistency asymptotic
2011/4/2
We suggest using a class of semiparametric dynamic panel data models to capture
individual variations in panel data. The model assumes linearity in some
continuous/discrete variables that can be exo...
