This study investigates how markets for different levels of copper purity are interrelated by testing the long-run price linkage and causalities among the copper futures, primary, copper scrap, and brass scrap markets. It is expected that copper markets that deal with high purity levels, such as the futures, primary, and copper scrap markets, have...

This study tests whether an international market exists in the platinum-group metal (PGM) futures markets. For this purpose, we tested the law of one price (LOP) and the causality between the U.S. and Japanese platinum and palladium futures markets. We also performed the test when structural breaks are considered. Long-run price relationships were...

This study analyzes the price linkage among the U.S. major energy sources, considering structural breaks in time series. We use the Johansen cointegration method and find that only weak linkage sustains among the NYMEX WTI crude oil, Brent crude oil, gasoline, heating oil, coal, natural gas, uranium, and ethanol futures prices. Our tests reveal...

This report covers the basic guidelines about AIM/Enduse model and some examples of its application. The report is created based on the AIM/Enduse Model Manual provided from the National Institute for Environmental Studies (NIES) where I had training to learn the model as a visiting scholar.

本研究では銅の先物市場、時価市場、純銅スクラップ市場、黄銅スクラップ市場という異なる銅市場を扱い、これらの間に価格連動性が存在するのかを検証することによって、銅スクラップ市場が現状として電気銅市場の代替市場としての役割を果たしているのかということについて見た。分析結果によると、電気銅純度が高く代替的関係にあると予測される先物市場、時価市場、純銅スクラップ市場の間には価格連動性があるのに対し、銅以外に亜鉛などを含む純度の低い黄銅スクラップとの間には価格連動性は存在しないということが示された。この結果から、純度の低いスクラップ市場は電気銅市場の代替市場としての機能を果たすことは難しいと考えられ、銅のスクラップ市場を有効的に活性化させていくためには...
