School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Unstable Individual Bids and Stable Market Demand § Hedonic scores and bids are measures the strength of individual preferences § We have two research questions in this paper: – Question 1 Are individual bids and hedonic scores stable? – Question 2: Will unstable individual bids (hedonic scores) result in stable market demand (stable market taste)? • Aggregation will wash out individual specific effects such as variety seeking behavior • Aggregation will wash out effects of random anchors such as exposition to advertising § Problem with material: 33 – How does it relate with existing literature? Discussed later! www. umb. no
NORWEGIAN UNIVERSITY OF LIFE SCIENCES Stability of Bids – Neoclassical Theory § Theory: Consumers’ choices are based on the maximization of a stable utility function subject to a budget constraint Bid § Stable individual preferences will, ceteris paribus, result in stable bids in experimental auctions conducted at different times S p. A § Stable individual bids is a sufficient but not a necessary condition for stable aggregate demand curves D A § Becker (1962), theoretical paper 34 – Showed how stable aggregate demand curves could be derived from random choices within the budget set www. umb. no 1 Quantity
NORWEGIAN UNIVERSITY OF LIFE SCIENCES Stable Preferences in Neoclassical Theory § What does “stability of preferences” mean? ? ? § “Constancy of tastes is a simplifying assumption, not an article of faith” (Silberberg and Suen 2001: 6) § The assumption of stable preferences for specific goods has been challenged in (for example) applied demand studies – Parametric as well as nonparametric methods (Varian) have been used – Stable preferences have been rejected (e. g. , Moschini and Meilke 1989; Jin and Koo 2003) and not rejected (e. g. , Chalfant and Alston 1988) § Alternative interpretations of stability of preferences are provided by: – Becker (1976: 5) who discuss stability of “underlying preferences” such as health, prestige, and envy 35 – Lusk and Briggeman (2009) who discuss stability of “food values” such as safety, nutrition, and taste www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Stability in Preferences over Specific Goods § We look at specific goods § In an empirical study of the Marseille fish market, Härdle and Kirman (1985) found: – Downward sloping aggregate but not individual demand curves – “Sophisticated and complicated individual behavior may lead to simple aggregate properties” – Similar to what we find in an experimental setting 36 www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Demand Curves § Individual demand curves are defined as: § The fish was sold in packages of about 300 grams – May be insufficient for a family meal – Participants could choose how many packages they wanted to buy for the market price before they started to bid – The quantity (x) counted as a 1 regardless of # of packages § The market demand curve is constructed by ranking the individual bids from the highest to the lowest, i. e. : 37 www. umb. no

School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Conclusions Paper § Unstable individual bids § Aggregation creates stable market demand § Random day-to-day variations in individual preferences have minor effects on the stability of the market demand § Good news for producers and retailers who are mainly interested in predicting the market demand 49 www. umb. no
NORWEGIAN UNIVERSITY OF LIFE SCIENCES School of Economics and Business Can We Explain the Changes in Individual Preferences? 50 www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Why Unstable Individual Demand Preferences? § According to economics, changes in demand can be caused by: – Changes in relative prices and income – Changes in quality (of heterogeneous goods) – Storage – Preferences – Socioeconomics § The marketing literature focus on changes in preferences from purchase-to-purchase occasion – Changes in external factors such as new information, available products, presence of other people, seasonality, etc – Changes in internal factors; consumers seek variety 51 www. umb. no
Department of Economics and Resource Management NORWEGIAN UNIVERSITY OF LIFE SCIENCES Why Unstable Individual Demand Preferences? § Behavioral economics focuses on effects of arbitrary anchors and the framing (of experiments) on preferences: – For example coherent arbitrariness (Ariely, Loewenstein, and Prelec 2003) • Are you willing to pay a dollar figure equal to the last two digits of your social security number for a “cordless keyboard” ? • State your WTP for “cordless keyboard” • Peoples absolute valuations affected by arbitrary anchors (social security number) • Peoples relative valuations coherent (as supported by a stable demand curve) 52 § If your social security number affects your WTP, then many other arbitrary variables will affect them! www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Preliminary Model § Try to explain hedonic scores and bids § We use the bids from all the experiments – We have 2, 425 hedonics scores including 53 zero scores – We have 2, 845 bids including 811 zero bids – Data are censored at zero § Tobit models to take account of these zero bids 53 www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Preliminary Model - Limitations § Some limitations in preliminary model: – A double hurdle model would be preferred, but we do not know how to estimate them given the panel nature of the data – Hedonic scores and bids both reflect preferences. Have not taken into account the endogeneity of hedonic scores in bid equations – Do not take censoring by market prices of field substitutes into account – Have not estimated relative bids and hedonic scores • Relative bids more consistent with theory 54 • Relative bids should wash out many of the systematic effects like CA and other random anchors – Have not looked at cross-price effects www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Preliminary Model - Variables § Hedonic scores for fish equation – Socioeconomic: Age and gender – Quality: Type of fish – Coherent arbitrariness: Test product orange juice or champagne? – Information: Country-of-origin and “wild or farmed” before tasting – Ordering: The first product typically receives the highest score – Time of the day: Lunch or dinner – Day of week effect: Monday-to-Friday or weekend fish § Additional variables in bid for fish equation – Prices of product: Bids are affected by the price of field substitutes – Quality: Hedonic score of fish 55 – Income – Information: Country-of-origin and “wild or farmed” before bidding www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Effects of Fish Type on Hedonic Scores Variable Parameter Constant 7. 49 WC -1. 36 § Reference product is salmon FC -1. 46 MO -0. 69 § Salmon is preferred to all other PA -4. 22 § All variables significant at the 1% level of significance fish types § Pangasius received an hedonic score that was 4. 22 lower than salmon 56 www. umb. no

School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Conclusions Survey Market Potential for Farmed Cod § A positive view on fish from North Atlantic as compared with other areas – Slightly more positive towards wild than farmed fish § Wild fish scores best on health and safety § Farmed fish scores better on environmental issues § Cod is a Monday-to-Friday fish – Can it be upgraded? They try! – Sustainable labeling? 60 www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Conclusions Hedonic Scores Market Potential for Farmed Cod § WC did on average better than FC § FC did better than WC in uninformed tasting § Segments are important – In December 2008, 60% preferred WC and 40% FC – Young participants preferred FC 61 www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Conclusions BDM Market Potential and WTP for Farmed Cod § WC received higher bids than FC on average – FC received higher bids than WC in uniformed bids • Can be explained by the higher hedonic score § Segments are important. In December 2008 – 36% bid more for FC than WC – 14% bid the same amount – 50% bid less for FC than WC § Strategies for FC – Difficult to take any higher price for FC than WC • Production costs critical 62 – Segments are important for FC – young people – To create value added product developments such as Ström may be a successful strategy www. umb. no
School of Economics and Business NORWEGIAN UNIVERSITY OF LIFE SCIENCES Some Other Conclusions § The market is characterized by – Unstable individual bids but stable market demand § Why unstable individual hedonics? – Fish type, CA, and ordering effects important § Why unstable bids? – Quality: Increasing hedonic scores increases bids – Outside prices: High outside prices increase the bids – CA: Expensive test product increases the bids – Females bid less 63 – Information about country-of-origin and “wild or farmed” increases bids – The bids increase towards the weekend www. umb. no
