Recent policy and research initiatives aim to make sustainable biofuel crops an important component of the nation’s agricultural and energy sectors, yet few studies have explored potential supply response at the farm level using survey information. This article utilizes contingent valuation...

Is the relationship between energy and agricultural commodities an important factor in the increasing price variability of food commodities? Findings from the literature appear to be mixed and highly influenced by the data frequency used in those analysis. A recurrent task in time series applied...
