| The US Environmental Protection Agency announced a waiver allowing an increase in the Fuel-Ethanol blend limit (the “blend wall” ) from 10% (E10) to 15% (E15) on October,2010.Justifications for the waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline, leading to energy security. In this paper, employing Monte Carlo simulations and Savitzky-Golay smoothing filter, an empirical study examines this waiver revealing an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are... |

| In this study, a Structural Vector Autoregression model (SVAR) is employed to decompose how supply/demand structural shocks affect food and fuel prices within fuel and corn markets. Results indicate that the relative importance of each structural shock in explaining the variation of corn prices is different. Our findings support the hypothesis that corn prices increase as a response to those positive demand shocks in the short run, while in the long run, global competitive agricultural commodities markets as well as positive supply shocks respond to commodity price shocks, restoring prices to its long-run trends. In conclusion, fundamental market forces of demand and supply as well as real economic aggregated demand shocks were the main contributors of the... |

| This paper investigates the impact of geographical origin labels on consumers' preferences. Specifically, we consider the preferences of Canadian consumers for extra virgin olive oils marketed with country-of-origin labels (COOL) and geographical indications (GIs). In contrast to previous studies, by considering a third-country market (a market different from that where production occurs), we can look simultaneously at COOL and GIs and separate the impacts of these two forms of geographical origin labels. We find that, within the context of a high quality value-added commodity such as extra virgin olive oil, consumers value both COOL and GI labels. But, in terms of the fraction of consumers with positive preferences and willingness to pay, COOL labels... |

| Early GM traits were obtained by transferring genes across species, largely from soil bacteria. Part of the consumer resistance to them has been their transgenic nature. Recently, breakthroughs have occurred using intragenic bioengineering where genes are moved long distances within a specie, for example in potato, and without antibiotic markers. The objective of this research is to assess consumers’ acceptance and willingness to pay (WTP) for new intragenic fresh potato, tomato, and broccoli with higher levels of antioxidants and vitamin C, which are consumer traits. To elicit consumer valuations, a new series of experimental auctions were conducted in 2007 that built upon methodology developed in our earlier research. WTP was assessed in a multi-round... |

| Most studies utilizing experimental auction mechanisms to elicit consumers’ willingness to pay are designed to avoid potential substitution or demand-curve effects that may influence bid prices. However, previous research and auction designs have not considered the potential impact on bid prices of commodity inventories held by auction participants that were obtained through transactions outside of the auction. This omission may present a problem for interpreting and analyzing auction data. Using bids from a random nth-price auction of fresh vegetables conducted in a laboratory style setting, we test whether participants’ outside inventories affect bidding behavior. We find that bidders do in fact consider their inventories, resulting in lower bid... |
