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,...

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....

The United States Environmental Protection Agency (EPA) has begun regulating existing stationary sources of greenhouse gases (GHG) using its authority under the Clean Air Act (the Act). The regulatory process under the Act is long and involved and raises the prospect that significant U.S. action...

We evaluate potential global impacts of increase in U.S. natural gas exports as a result of the shale gas boom. To our knowledge this is the first such analysis using a global economic model to understand this timely policy issue. Our primary conclusion is that world economic activity is higher...

Indonesia is the world’s largest importer of its staple food, rice. Since the economic crisis of 1998, rice import policy has become increasingly protectionist and since early 2004, imports have been banned. This paper uses a general equilibrium model of the Indonesian economy to analyze the...

This paper examines Australia's terms of trade boom since 2003 with a particular interest in quantifying the links between the terms of trade and sectoral performance and identifying an associated 'secondary services boom'. Comparative static general equilibrium modelling and empirical analysis...

Australia’s comparatively small and open economy is subject to boom-bust shocks that centre on its exporting mining and agricultural industries which, in average years, are minor contributors to its GDP. The associated real exchange rate effects, however, have important implications for...
