  • Personalized pricing and price fairness

    Timothy J. Richards, Jura Liaukonyte, Nadia A. Streletskaya, International Journal of Industrial Organization, 44: 138–153, 2016

    Mobile web technology enables discriminatory, or personalized, pricing for many more consumer good categories than has traditionally been the case. Setting prices according to individual valuations, however, generates adverse consumer reaction unless consumers are invited to participate in the price-formation process. Consumer perceptions of price fairness are key to the sustainability of any discriminatory pricing regime. Perceptions of price fairness, in turn, are hypothesized to be shaped by “self-interested inequity aversion” in which prices tend to be regarded as unfair, and purchase probabilities fall, if others are perceived to pay a lower price, while prices tend to be regarded as more fair, and consumers more likely to purchase, if inequity is in the buyers favor. Our experimental data also shows that the implications of inequity aversion for sellers can be at least partially reversed if consumers are allowed to participate in the price-formation process by negotiating the price they pay. The primary implication of our findings is that, in order to be viable, any system of discriminatory pricing for consumer goods should invite consumers to have a stake in the price they pay. Such participatory pricing may provide one way out of the current trap of Hi–Lo, or promotional, pricing that neither retailers nor manufacturers regard as sustainable.

  • Menu-labeling formats and their impact on dietary quality

    Nadia A. Streletskaya, Wansopin Amatyakul, Pimbucha Rusmevichientong, Harry M. Kaiser and Jura Liaukonyte. Agribusiness: an International Journal, 32(2): 175-188, 2016

    The impact of three menu-labeling formats on changes in dietary quality of an away-from-home meal is measured. The analysis is based on a lunchtime experiment using 232 student participants, with a control group and three treatments: (1) a calorie-content posting, (2) a complete nutrition-facts panel, and (3) health-related claims. We find that the calorie content posting lead to the highest calorie reduction, but it was also the only treatment associated with a significant reduction in the fiber content of the meal. The complete nutrition-facts panel treatment resulted in most sizable decreases in problematic nutrient content such as empty calories and calories from fat and added sugar. The health-related claims treatment led to a reduction in carbohydrates and calories from fat. The nutrient density of selected meals remained mostly unchanged across all treatments, but the empty calories proportion of total calories was reduced in the nutrition-facts and health related claims treatments, with the latter also leading to some reduction in added sugar density.

  • The long term impact of positive and negative information on food demand

    Jura Liaukonyte, Nadia A. Streletskaya and Harry M. Kaiser. Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, 63(4): 539-562, 2015.

    We examine whether the effects of information about product labels change over time.  The analysis is based on 110 adult (non-student) subjects who participated in a two-stage economic experiment taking place three months apart. In the first stage of the experiment, willingness-to-pay (WTP) was elicited for items that were stated to contain bovine growth hormones, genetically modified ingredients, ingredients that have been exposed to antibiotics, and ingredients that were irradiated. Depending on the treatment, each first stage auction was supplemented with positive or negative information about each of the labels. The second stage experiments re-elicited WTP for the same group of subjects and the same items accompanied with the original labels, but this time without any secondary information. Our results suggest that the adverse impact of negative information does not persist over time; whereas in the case of positive information, changes in WTP from the initial to the follow-up auctions are not statistically significant. This study enhances our understanding of how consumers retain information over a longer time period and suggests that previous studies that measure labeling impacts on WTP using isolated, single-shot experiments may overstate the longer-term effects of labels and negative information.

  • Noisy information signals and endogenous preferences for labeled attributes

    Jura Liaukonyte, Nadia A. Streletskaya and Harry M. Kaiser. Journal of Agricultural and Resource Economics, 40(2): 179-202, 2015

    Consumer preferences for labeled products are often assumed to be exogenous to the presence of labels. However, the label itself (and not the information on the label) can be interpreted as a noisy warning signal. We measure the impact of “contains” labels and additional information about the labeled ingredients, treating preferences for labeled characteristics as endogenous. We find that for organic-food shoppers, the “contains” label absent additional information serves as a noisy warning signal leading them to overestimate the riskiness of consuming the product. Providing additional information mitigates the large negative signaling effect of the label.

  • Taxes, subsidies, and advertising efficacy in changing eating behavior: an experimental study

    Nadia A. Streletskaya, Pimbucha Rusmevichientong, Wansopin Amatyakul and Harry M. Kaiser. Applied Economic Perspectives and Policy, 36(1): 146-174, 2014

    Using a lab experiment with 258 adult non-student participants, we examined whether unhealthy foods taxes, healthy foods subsidies, anti-obesity advertising, and healthy foods advertising have an impact on changing consumers’ choices of lunch items and the nutrient content of their choices for a selected meal. A difference-in-difference regression model was used to determine the efficacy of the various policy treatments. The results indicate that the unhealthy foods tax, healthy foods advertising, and unhealthy foods tax combined with anti-obesity advertising significantly reduced the content of some nutrients of concern, such as calories, calories from fat, carbohydrates, and cholesterol in meal selections. We also find that when combined with healthy foods subsidy, the healthy foods advertising has very little effect on nutrient consumption; the anti-obesity advertising on its own, however, is not efficient at changing dietary behavior. We discuss the policy implications of our findings and venues for future research.

     

  • Response to Comment on taxes, subsidies, and advertising efficacy in changing eating behavior: an experimental study

    Nadia A. Streletskaya and Harry M. Kaiser. Applied Economic Perspectives and Policy, 36(4): 722-726, 2014

    Experimental design is a crucial component to economics lab studies, and its structure defines the research agenda and the questions that can be answered through the data obtained in the experiment. Designing an effective economics laboratory experiment involves not only navigating the basic principles of experimental design, such as orthogonality and incentive compatibility, but also taking into account human behavior, heuristics, and learning. Although we commend the comment (Fischer forthcoming) for not simply taking the research conclusions at their face value and for delvingdeeper into the intricacies of the experimental design used in “Taxes, Subsidies, and Advertising Efficacy in Changing Eating Behavior: An Experimental Study” (Streletskaya et al. 2014), we feel it is necessary to correct the false assumptions the comment depends upon and use the data from the original experiment to examine some of the comment's claims. It is our hope that such a discussion of experimental design will highlight the necessity to holistically approach the evaluation of experimental studies in economics, necessarily looking at both the data and the design structure to judge research results.

  • The impact of food advertisements on changing eating behaviors: an experimental study

    Pimbucha Rusmevichientong, Nadia A. Streletskaya, Wansopin Amatyakul and Harry M. Kaiser. Food Policy, 44: 59-67, 2014.

    This research examines how three types of food advertising (healthy food, unhealthy food, and anti-obesity) impact consumers’ purchases of lunch items. The analysis is based on an economic experiment conducted with 186 adult non-undergraduate student subjects, each of which were randomly placed into either the control group or one of four treatments: (1) healthy food advertising, (2) anti-obesity advertising, (3) unhealthy food advertising, and (4) mixed (all three food) advertising. The results indicate that healthy, anti-obesity, and mixed food advertising reduced intakes of total calories, fat, sodium, and carbohydrates. Similarly, anti-obesity, healthy, and mixed food advertising results in increasing the probability of selecting more healthy items and fewer unhealthy items from a menu. Healthy food advertising has a stronger impact than anti-obesity or mixed food advertising.

  • Consumer response to “Contains” and “Free of” labeling: evidence from lab experiments

    Jura Liaukonyte, Nadia A. Streletskaya, Harry M. Kaiser, and Bradley J. Rickard. Applied Economic Perspectives and Policy, 35(3): 476- 501, 2013.

    Using a lab experiment with 351 adult non-student subjects, we investigate the impact of labels and secondary information on willingness to pay (WTP) for foods that use various ingredients and processes that have been the subject of food policy discussions. We find a distinct asymmetry of WTP sensitivity between “Contains X” and “Free of X” labels with negatively-framed secondary information. The “Free of X” label has an impact only when secondary information is provided, and the negative impact of “Contains X” is mitigated by secondary information. We also consider how the results of our study can inform the ongoing debate about mandatory food labeling regulations in the United States: if mandatory labeling is adopted, providing additional information about what the product contains would significantly lessen the negative impact on demand.

Teaching at Oregon State:

  • Agricultural and food marketing (AEC 221)

    Winter 2017, Spring 2018

    Currently capped at 60 students. The course covers the traditional agricultural marketing topics, including market structure and organization, marketing chains and marketing orders, as well as the more consumer oriented side of food marketing, including labeling and a wide array of food policies affecting consumer decision making.

  • Intermediate applied economics: producers and consumers (AEC 311)

    Winter 2018

    The course provides an en examination of the theories of consumer behavior and demand, production cost, the firm, supply, and competitive market structure. Part of the aplpied microeconomics sequence, followed by AEC 313.

  • Behavioral and experimental economics (AEC 699)

    Winter 2018

    This course provides introduction to the concepts of behavioral economics and a primer on experimental methods. Experimental and behavioral economics are exciting fields in the broader economics discipline, with experimental economics focusing on controlled identification, illustration and study of various socio-economics principles and market mechanisms, and behavioral economics research tackling situations that are inconsistent with the standard rational behavior model on both individual and market level. Concepts and tools presented in the class can be used in a variety of settings, including provision of environmental services, health and social policy design, marketing and product design.

Past teaching:

  • Behavioral economics section, Advanced topics in environmental and resource economics (AEC 448/548)

    Fall 2016, 3-week section of the AEC 448/548

    The section introduces and discusses some basic concepts of behavioral economics dealing with judgement biases and heuristics, time effects, and risk preferences. The student complete a short research proposal, with a preferable focus on environmental and resource economics, that uses, tests or studies the concepts introduced in the section.
