We investigate the mechanisms that shape social comparison in organizations and generate socialcomparison costs. In particular, we focus on heterogeneity in the strength and type of incentivesand argue that, from an efficient design perspective, such variance in rewards is a double edgedsword. While the sorting and incentive effects that result may increase productivity, the socialcomparison processes that arise may dampen it. We posit that the mechanisms underlying thesebehavioral costs are shaped not only by the magnitude of reward variance, but by the formal andinformal design elements shaping the distance of advantaged peers. In other words, the moreproximate socially, structurally or geographically are those to whom one socially compares, thelarger the behavioral response. Empirically, we use an unanticipated event during which outlets ofa bank, previously operating under essentially homogenous incentives, were assigned totournament groups with differing ex ante probabilities of winning a prize—an event that increasesvariance in awards and hence generates an impetus for social comparison. We find that units withmore socially, geographically, and structurally proximate peers assigned to ‘advantaged’tournament groups decreased their productivity. We discuss implications of these results fororganizational design and boundaries

We consider a single-stage multiproduct manufacturing facility producing a large number of end products.In order to reduce overall inventory costs, an efficient approach is to produce some items according to amake-to-stock (MTS) policy and others according to a make-to-order (MTO) policy. Items priority levelsplay a key role in the optimal MTO/MTS decisions for such typical large-scale systems. To tackle this issue,the manufacturing facility is modeled as a multiproduct multipriority classes queuing system. We proposea general optimization procedure that selects near-optimal priority classes, gives the associated flow controlmode (MTO or MTS) for each product, and provides a lower bound and an upper bound with respect to theoptimal cost. First, we illustrate efficiency of our optimization procedure for this class of nonlinear integerprograms via several examples and by a numerical analysis, including a comparison with two alternativeheuristics given in the literature. In addition, we provide managerial insights by exhibiting, under variousparameter settings, the significant impact of an efficient priority level allocation among items on the inventorycosts and on optimal splitting between MTO and MTS product

Reinforcing the Public Law Taboo: A Note on Hellenic Republic v Nikiforidis

This article hinges on the preliminary ruling rendered by the Court of Justice of the European Union (ECJ) (Grand Chamber) on 18 October 2016 and the related judgment of the German Federal Labour Court of 26 April 2017 in the Nikiforidis case to investigate an area of private international law that is undergoing a substantial development: overriding mandatory provisions. In Nikiforidis, the ECJ excluded that two Greek laws cutting the salary of public employees may be enforced against a teacher working in Germany for the Greek government under an employment contract governed by German law. The question addressed to ECJ was whether said laws were “overriding mandatory provisions” according to the Rome I Regulation. The court denied it, and left to the referring court to determine whether they could nevertheless operate “as matter of fact” under the governing law. This article explains how the ECJ’s conclusion has broader implications by regulating third countries’ interference in international business transactions. Starting with an analysis of the case, the article examines the history and nature of overriding mandatory provisions under EU private international law and argues that the solution embraced by the ECJ leaves room to uncertainty and unpredictability in the operation of foreign mandatory provisions

Shine on me: Industry coherence and policy support for emerging industries


Administrative Science Quarterly

It has long been recognized that government support can catalyze the emergence and growth of new industries. But under what conditions does an emergent category of organizations come to receive state support in the first place? In this paper, we theorize how government support for a nascent industry is jointly determined by the industry's internal features and external forces. We test our arguments by analyzing feed-in-tariff policies for the emergent solar photovoltaics (PV) industry in 28 European countries over more than two decades. We find that feed-in-tariffs were more likely in countries with greater numbers of solar PV producers and in countries where the industry was more coherent, containing fewer producers coming from industries with a contrasting identity. Further, we find that the concentration of the incumbent energy sector enhances the effect of the number of producers on policy support when the industry is coherent, but not when it is incoherent. Our results shed new light on the relationship between public policy and industry category emergence, and extend our understanding of how new industries can attain valuable state support while operating in seemingly hostile environments

Social Presence in Virtual World Collaboration: An Uncertainty Reduction Perspective Using a Mixed Methods Approach


MIS Quarterly

Départements : Information Systems and Operations Management, GREGHEC (CNRS)

Mots clés : Virtual worlds, uncertainty reduction theory, institutional trust, sequential mixed methods

The life-like collaborative potential offered by virtual worlds (VWs) has sparked significant interest for companies to experiment with VWs in order to organize convenient, cost-effective virtual global workplaces. Despite the initial hype, recent years have witnessed a rather stagnant use of VWs for collaboration in organizations. Previous research recognizes that the inherent uncertainties within the VW environment are factors limiting their utilization by businesses. Hence, grounding this research in uncertainty reduction theory (URT), we aim to understand the modalities and mechanisms for mitigating the uncertainties and fostering user trust within VWs so that they can be effectively utilized as a workplace collaboration tool. With this end in view, we propose contextualizing and extending McKnight et al.’s (2002) institutional trust framework to the context of VWs by examining the significant role that social presence has in influencing the efficacy of the institution-based trust-building factors of situational normality and structural assurance in VWs. Using a sequential mixed methods approach (Venkatesh et al. 2013; Venkatesh et al. 2016), this research integrates results from a quantitative study with findings from a qualitative study to arrive at rich and robust inferences and meta-inferences, with the qualitative method first corroborating the inferences obtained from the quantitative research and then complementing them by identifying boundary conditions that may limit the use of VWs in organizations for workplace collaboration. The results together suggest not only the direct, but also the interactional (complementary and substitutive) influences of social presence on the relationships of the two institutional-trust-building factors to user trust in VWs

Strategic Default, Debt Structure, and Stock Returns

Mots clés : Debt Structure, Debt Renegotiation, Stock Returns

This paper theoretically and empirically investigates how the debt structure and the strategic interaction between shareholders and debt holders in the event of default affect expected stock returns. The model predicts that expected stock returns are higher for firms that face high debt renegotiation difficulties and that have a large fraction of secured or convertible debt. Using a large sample of publicly traded US firms between 1985 and 2012, the paper presents new evidence on the link between debt structure and stock returns that is supportive of the model's predictions

Mots clés : Art museums, Authenticity, Digital policies, Real/virtual relationship, Cultural audiences, Measures in art

The technological shift of museums is extensively documented, even if research on the impact of technologies on cultural practices and social patterns at large is still lacking. As part of a research programme conducted by the Louvre and HEC Paris, the article proposes a conceptual analysis of ‘real’ (visiting the museum) and ‘virtual’ (visiting its website) experiences of museums. It contributes to the understanding of whether the two experiences are substitutes or complements using a newly created measurement scale. In addition, the article also aims at enriching the contemporary discussion on the artworks’ aura and the authenticity of the cultural experience in the digital age
