A comparison of hypothetical survey rankings with consumer shopping behavior and product knowledge AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa.
Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations.We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

A Return of the Threshing Ring? A Case Study of Machinery and Labor-Sharing in Midwestern Farms AgEcon
Artz, Georgeanne M.; Colson, Gregory; Ginder, Roger G..
Machinery-sharing provides an alternative for smaller producers to obtain the efficiencies of large farming operations and remain competitive in an increasingly concentrated agricultural industry. This research uses a multiple case study design to examine the motivations for sharing equipment and labor among farms and to better understand how group members handle the transaction costs of sharing. Our case evidence finds that in addition to cost savings, access to reliable labor is an important motivation for participating in a sharing arrangement. Trust and frequent communication among group members helps to minimize the transaction costs incurred from sharing.

An Ethanol Blend Wall Shift is Prone to Increase Petroleum Gasoline Demand AgEcon
Qiu, Cheng; Colson, Gregory; Zhang, Zibin; Wetzstein, Michael E..
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...

Analyzing pork purchases at the point of sale – The role of consumer involvement AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa.
Involvement is an important psychological construct for understanding consumers’ underlying purchase decision process and those factors that shape product perceptions. In order to better understand consumer purchase behavior for low and high priced pork cuts, a series of field interviews at a variety of food retailers were conducted with actual pork shoppers using the New Involvement Profile (NIP) developed by Jain and Srinivasan (1990). In addition to responses to a series of questions designed to assess consumers’ involvement when purchasing pork, informational elements including socio-demographic information and pork attributes (e.g., origin, advertisement, on sale) were also included in the analysis. Key results from the study show individuals with...

Considering Macroeconomic Indicators in the Food versus Fuel Issues AgEcon
Qiu, Cheng; Colson, Gregory; Wetzstein, Michael E..
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...

Consumer preferences for extra virgin olive oil with country-of-origin and geographical indication labels in Canada AgEcon
Menapace, Luisa; Colson, Gregory; Grebitus, Carola; Facendola, Maria.
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...

Consumers’ Willingness to Pay for New Genetically Modified Food Products: Evidence from Experimental Auctions of Intragenic and Transgenic Foods AgEcon
Colson, Gregory; Huffman, Wallace E..
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...

Demand Curve Effects in Experimental Auctions: The Effect of Quantity Already Owned AgEcon
Colson, Gregory; Huffman, Wallace E.; Rousu, Matthew C..
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...

Improving the Nutrient Content of Food through Genetic Modification: Evidence from Experimental Auctions on Consumer Acceptance AgEcon
Colson, Gregory; Huffman, Wallace E.; Rousu, Matthew C..
This paper assesses consumers’ acceptance of nutritionally enhanced vegetables using a series of auction experiments administered to a random sample of adult consumers. Evidence suggests that consumers are willing to pay significantly more for fresh produce with labels signaling enhanced levels of antioxidants and vitamin C achieved by moving genes from within the species, as opposed to across species. However, this premium is significantly affected by diverse information treatments injected into the experiments.

Who cares about food origin? A comparison of hypothetical survey responses and actual shopping behavior AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa; Bruhn, Maike.
This paper explores the relevance of food origin to consumers when making product purchase decisions. We use data from a survey of pork shoppers at the point of sale of five food retailers in Germany. Participants engaged in both a hypothetical survey eliciting evaluations of the importance of different pork attributes and a series of questions related to their knowledge about the attributes of their actual purchase of pork. This enables us to compare hypothetical responses with actual purchase behavior. The results show that origin indeed is a relevant attribute to a subset of consumers. A share of consumers does pay attention to origin labels and is willing to undertake costly search for origin information. Furthermore, the data give evidence that...
