Financial Risk Proneness Explains the "Sex Sells” Hypothesis in Relation to Luxury Brands
No full textInternational audienceOwing to their premium prices, luxury brands carry considerable financial risk for consumers. Drawing from evolutionary research, we theorize that exposure to eroticism in luxury advertising enhances consumers’ willingness to take financial risks and, through it, evaluations of the advertised brand. We test these expectations experimentally in two studies (N = 465; N = 105) and for three categories of luxury brands (wristwatches, vodka, and perfumes), using different measures of risk proneness and brand evaluations. Both studies lend broad support to our expectations. We find that increased risk proneness through erotic advertising in the field of luxury goods improves brand evaluations if the goods can be used for conspicuous consumption and in all model-gender/consumer-gender combinations except of the male-model/male-consumer constellation

A cross-verified database of notable people, 3500BC-2018AD
No full textInternational audienceA new strand of literature aims at building the most comprehensive and accurate database of notable individuals. We collect a massive amount of data from various editions of and . Using deduplication techniques over these partially overlapping sources, we cross-verify each retrieved information. For some variables, adds 15% more information when missing in . We find very few errors in the part of the database that contains the most documented individuals but nontrivial error rates in the bottom of the notability distribution, due to sparse information and classification errors or ambiguity. Our strategy results in a cross-verified database of 2.29 million individuals (an elite of 1/43,000 of human being having ever lived), including a third who are not present in the English edition of . Data collection is driven by specific social science questions on gender, economic growth, urban and cultural development. We document an Anglo-Saxon bias present in the English edition of , and document when it matters and when not
"Perceiving control over the exchange on peer-to-peer platforms: measurement and effects in the second-hand market"
No full textInternational audienceWhile the emergence of peer-to-peer (P2P) platforms has revolutionized the way people exchange goods, these platforms face the need to provide appealing products offered by independent providers. However, those providers have to deal with anonymous buyers, potentially hindering their perception of control over the exchange and their subsequent willingness to use the platform. Our research addresses this issue of providers' control. Because prior research uses either environment-centric or individual-centric measures of control, no accurate measure of perceived control exists. This research aims to contribute by providing a scale that-in line with control theories-differentiates among the perceptions of control that derive from individual (i.e., skills-related) and those that emerge from the environment (i.e., security-related, autonomy-related). The results of four empirical studies performed in the secondhand market provide strong empirical support for the validity of our control scale, and its ability to explain the provider's experience on the P2P platform
An integrated global airline hub network design with fleet planning
No full textInternational audienceThis study aims to locate optimal global hubs for an airline or a group of airlines to cover international flights between countries. Despite designing a hub network for regional flights, designing a hub network for international flights is considerably different because of the high frequency of medium-, or long-haul flights. Accordingly, designing a hub network without considering the fleet size and diversity is impossible. This study proposes three airline Hub Location Problems (HLPs) in a global scale with the following considerations: Ι) an HLP providing the possibility of operating the multi-leg flights by a limited fleet size, ΙΙ) an HLP respecting consideration (Ι) with the possibility to increase the efficiency of the fleet by taking the aircraft characteristics into account in the design of the hub network, and ΙΙΙ) an HLP respecting considerations (Ι) and (ΙΙ) with the possibility of fleet planning. These models are solved for several instance networks, being up to 300 networks, and compared with an HLP without these considerations. The results mainly demonstrated that ignoring the aircraft characteristics in an HLP can generate an inefficient or infeasible hub network configuration. In addition, the problem of a real international flight network was solved and the insights regarding designing an optimal hub network and fleet configuration were presented

The size effect and default risk: Evidence from the Vietnamese stock market
No full textInternational audienceThe literature is inconclusive on the source of the size effect. Our paper contributes to extant studies by investigating the relationship between the size premium and default risk in Vietnam, an important frontier emerging market. The debt-to-equity ratio and distance-to-default of Merton (1974, The Journal of Finance, 29, 449) are used as distress-risk proxies. Based on more than 300 listed stocks over 2009–2019, we discover that the small portfolio delivers the highest average return. The excess return on the small portfolio is concentrated in firms with high distress risk. Furthermore, neutral size factors are built to dissect returns on the Fama-French size factor from the default-risk premium. Empirical results prove that the explanatory power of the size factor is negatively affected when the default-risk neutrality is applied. Given this backdrop, the size premium in Vietnam is likely to be compensation for distress risk, consistent with a risk-based point of view
