TL;DR: The authors investigated the information transmission mechanism by looking at spillover effects and identifying which market is the true price leader in the energy market, and found that substantial spillover effect does exist when both markets are trading simultaneously, although IPE morning prices seem to be considerably affected by the close of the previous day on NYMEX.

TL;DR: In this paper, the authors investigate evidence on the effects of OPEC announcements on world oil prices by examining announcements from both official conferences and ministerial meetings on major international crudes, including the key benchmarks and several other heavy and light grades.

TL;DR: In this article, the authors employed a VAR-BEKK model to investigate crude oil markets integration on the second moment, and quantified the size and persistence of these connections through the analysis of Volatility Impulse Response Functions (VIRF) for two historical shocks.

TL;DR: In this paper, the authors investigated the possible existence of a two-tier spot freight market for medium and large bulk carriers of differing age and found that there was no statistically significant difference between rates paid to older and younger ships.

TL;DR: In this article, a series of statistical tests were performed with the aim of detecting the existence of any premium paid for vessels of lower age, double hull construction, or trading to the U.S.A. The results were mixed, indicating in several cases some form of premia for US.-bound vessels, but less evidence of premies for lower age and better hull construction.
