This paper describes the major issues in the clearing of over-the-counter (OTC) derivatives and the current regulative initiatives aimed at removing the market opaqueness. The core of the paper is the comparison of the US Dodd-Frank Wall Street Reform and Consumer Protection Act and the European...

We use the wavelet coherence methodology to investigate relations between prices of ethanol and its feedstocks. Our continuous wavelet framework allows for discovering price connections and their evolution in both time and frequency domain in the most important ethanol markets – Brazil and the...

We propose a new approach to analyze relationships and dependencies between price series. For the biofuels markets and the related commodities, we study their mutual responsiveness, which can be understood as price cross-elasticities. Several methodological caveats are uncovered and discussed....

For the first time, we apply the wavelet coherence methodology on biofuels (ethanol and biodiesel) and a wide range of related commodities (gasoline, diesel, crude oil, corn, wheat, soybeans, sugarcane and rapeseed oil). This way, we are able to investigate dynamics of correlations in time and...

We analyze the relationships between biodiesel, ethanol and related fuels and agricultural commodities with a use of minimal spanning trees and hierarchical trees and Granger causality. We construct this trees for different frequencies (weekly, monthly and quarterly). We find that in short-term,...
