Energy futures have become important as alternative investment assets to minimize the volatility of portfolio return, owing to their low links with traditional financial markets. In order to make energy futures markets grow further, it is necessary to expand expectations of returns from trading...

This article examines the performance of three multivariate conditional volatility models with respect to crude oil spot and futures returns: the Dynamic Conditional Correlation (DCC) model, Asymmetric Dynamic Conditional Correlation (A-DCC) model and Diagonal Baba-Engle-Kraft-Kroner (Diagonal...

We apply the lag-augmented vector autoregression technique to test the Granger-causal relationships among wholesale electricity prices, natural gas prices, and crude oil prices. In addition, by adopting a cross-correlation function approach, we test not only the causality in mean but also the...

This study examines whether the spot prices in the Japan Electric Power Exchange are efficiently formed from April 3, 2006, to March 31, 2012, using the conventional and rank-based variance-ratio tests. The results seem to reject the efficient market hypothesis in the market. Moreover, by...

Purpose: The purpose of this paper is twofold. First, the paper examines the risk transmission between crude oil and petroleum product prices of Japan’s oil futures market. Second, it compares the performance of two tests for Granger causality using realized variance (RV) and the exponential...

About ten years have passed since the deregulation of the U.S. retail electricity market, and it is now generally accepted that the available data is adequate to quantitatively assess and compare conditions before and after deregulation. This study, therefore, estimates the changes in price...

This paper examines the residential demand for electricity in Japan, excluding Okinawa-prefecture, from 1975 to 2005 as a function of the disposable income per household and the overall unit price of electricity for general consumers, by using the empirical panel analysis techniques of a panel...
