A dynamic herding model with interactions of trading volumes is introduced. At time $t$, an agent trades with a probability, which depends on the ratio of the total trading volume at time $t-1$ to its own trading volume at its last trade. The price return is determined by the volume imbalance...

We present a relatively detailed analysis of the persistence probability distributions in financial dynamics. Compared with the auto-correlation function, the persistence probability distributions describe dynamic correlations non-local in time. Universal and non-universal behaviors of the...

A simple trading model based on pair pattern strategy space with holding periods is proposed. Power-law behaviors are observed for the return variance $\sigma^2$, the price impact $H$ and the predictability $K$ for both models with linear and square root impact functions. The sum of the traders'...

The Yangtze River Economic Belt (YEB) and the Yellow River Ecological Economic Belt (YREB) surround the two biggest inland rivers and emit the greatest amount of carbon emissions in China. In order to implement China's dual carbon goal, this research applies a Meta-frontier DN-DEA model,...

A web service choreography standard enables a standardized description of business processes that allows not only a clear specification of the control flow, but also forms the basis for the actual process execution. Such standards are part of the web services stack and facilitate enterprise...

We investigate the spatial and temporal structures of four financial markets in Greater China. In particular, we uncover different characteristics of the four markets by analyzing the sector and subsector structures which are detected through the random matrix theory. Meanwhile, we observe that...

With the network methods and random matrix theory, we investigate the interaction structure of communities in financial markets. In particular, based on the random matrix decomposition, we clarify that the local interactions between the business sectors (subsectors) are mainly contained in the...

An attempt was made to conduct spatial assessment of the pattern and extent of damage to coastal aquaculture ponds along the east coast of Aceh province in Sumatra, Indonesia, resulting from the tsunami event of 26 December 2004. High-resolution satellite imagery, i.e., SPOT-5 multispectral...

This paper examines the impact of export orientation, import competition, foreign ownership and the rate of capital accumulation on the relative demand for skilled and unskilled labor in pre-crisis Indonesia.

In this paper we model the transition process in China. First we review the economic reform policies since 1978. Based on the review, a two-segment-model is constructed. The model can be viewed as a general equilibrium model, with a planned segment that produces some distortion in the model, and...
