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...
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 ...
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...
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,...
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...
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 (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...
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...
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...
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...
The article presents an analysis on the monetary policy transparency and private sector in the U.S. It provides a framework for discussing monetary policy transparency and how transparency is related ...
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...
This paper considers the estimation and testing of a within-group two-stage least squares (TSLS) estimator for instruments with varying degrees of weakness in a longitudinal (panel) Data model. We sho...
