This paper extends Hong et al. (2007)’s model-free test to analyze the contagion. A simulation experiment reveals that our test has reasonable size and good power in finite sample. We use this test and find the strong evidence of contagion between crude oil and stock markets.

This paper develops two tests for parametric volatility function of a diffusion model based on Khmaladze (1981)’s martingale transformation. The tests impose no restrictions on the functional form of the drift function and are shown to be asymptotically distribution-free. The tests are...

Purpose– This study aims to propose a model-free statistic that tests asymmetric correlations of stock returns, in which stocks move more often with the market when the market goes down than when it goes up, and then empirically analyze the asymmetric correlations of the China stock market and...

Purpose–The purpose of this paper is to empirically analyze the dynamic relationship between stock market and bond market based on the effect of different information shocks. Design/methodology/approach–This paper decomposes the information of stock market and bond market into public...

Subsynchronous oscillation (SSO) of generators caused by high voltage direct current (HVDC) systems can be solved by applying supplemental subsynchronous damping controller (SSDC). SSDC application in mitigating SSO of single-generator systems has been studied intensively. This paper focuses on...

China's major wheat producing areas play a crucial role in ensuring domestic grain production and food security more generally and it is therefore of significance, both empirically and theoretically, to investigate the current situation and future tendencies of the sector. Based on input- and...

We analyze the properties of the implied volatility, the commonly used volatility estimator by direct option price inversion. It is found that the implied volatility is subject to a systematic bias in the presence of pricing errors, which makes it inconsistent to the underlying volatility. We...

The core-periphery (CP) model of urban systems lacks evidence from real data for the nonlinear relationship between distance to core and market potential. China remains in the process of industrialization and globalization, thereby making it suitable for practical application of the CP model of...
