Buy baits and consumer sophistication: field evidence from instant rebates
No full textAre consumers in the marketplace aware of their cognitive limitations? I answer this question in the context of a ubiquitous form of price discrimination: “instant rebates" that require active redemption. In a large-scale field experiment with a major online retailer, I find that consumers correctly increase demand when the firm offers a redemption reminder, but they fail to reduce demand when the firm increases the hassle required to redeem. Structural estimates reveal that, while consumers are fairly sophisticated about the probability of forgetting to redeem the rebate, they vastly underestimate the hassle of redeeming it by 20 EUR per consumer
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Willingness to Pay for Carbon Mitigation: Field Evidence from the Market for Carbon Offsets
No full textWhat do markets for voluntary climate protection imply about people's valuations of en- vironmental protection? I study this question in a large-scale field experiment (N=255,000) with a delivery service, where customers are offered carbon offsets that compensate for emissions. To estimate demand for carbon mitigation, I randomize whether the delivery service subsidizes the price of the offset or matches the offset's impact on carbon mitigation. I find that consumers are price-elastic but fully impact-inelastic. This would imply that consumers buy offsets but their willingness to pay (WTP) for the carbon it mitigates is zero. However, I show that consumers can be made sensitive to impact through a simple information treatment that increases the salience of subsidies and matches. Salient information increases average WTP for carbon mitigation from zero to 16 EUR/tCO2. Two complementary surveys reveal that consumers have a limited comprehension of the carbon-mitigating attribute of offsets and, as a result, appear indifferent to impact variations in the absence of information. Finally, I show that the widely-used contingent valuation approach poorly captures revealed preferences: Average hypothetical WTP in a survey is 200 EUR/tCO2, i.e., 1,150% above the revealed preference estimate
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Buy baits and consumer sophistication: Theory and field evidence from large-scale rebate promotions
No full textCan firms exploit behavioral biases to increase profits? Does consumer sophistication about these biases limit the scope of exploitation? To answer these questions, I run a series of natural field experiments with over 600,000 consumers and estimate novel sufficient statistics of consumer sophistication. The empirical application is a ubiquitous and widely regulated form of price discrimination: rebates that need to be actively claimed by consumers. These promotions are suspected of boosting sales even though many consumers eventually fail to claim the rebate-a phenomenon marketers refer to as "slippage." I show theoretically that consumers' subjective redemption probabilities can be inferred from how demand responds to rebates as opposed to simple price reductions. I identify these elasticities in three natural field experiments with a major online retailer, in which I randomize prices, redemption requirements, and reminders. Results reveal that claimable rebates in fact increase sales substantially even though 47% of consumers do not redeem the rebate. However, consumers exhibit a remarkable degree of sophistication: the demand response to a rebate is only 76% of the demand response to an equivalent price reduction. Structural estimates imply that consumers almost perfectly anticipate their inattention but vastly underestimate the hassle of redemption by 20 EUR per consumer. Exploiting this misperception increases the profitability of rebates by up to 260%
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
