Network Agency in Entrepreneurship : A Synthesis and Outlook
No full textInternational audienceNetwork agency matters in entrepreneurship. As purposeful agents, entrepreneurs actively interact with their surroundings. However, scholars only have limited and dispersed knowledge about the antecedents, mechanisms, and outcomes of entrepreneurs’ network agency. We performed an integrative review of network agency in entrepreneurship to provide a much-needed synthesis of the fragmented insights into this topic. By moving away from a deterministic approach in which social structures shape entrepreneurs’ destinies and toward an agentic approach in which social networks shape entrepreneurs while simultaneously being shaped, managed, and developed by them, we contribute to a refined understanding of social networks.<br /
Perpetuating enforcement weakness : entrepreneurs’ destructive actions in normalizing rule-breaking
No full textInternational audienceEntrepreneurs’ rule-breaking behavior in its various forms is prevalent across settings, undermining economic and societal values. Previous research has explored rule-breaking in emerging economies, often attributing noncompliance to cumbersome regulatory frameworks. However, there is limited understanding of how entrepreneurs actively undermine enforcement efforts to normalize rule-breaking. In this study, we examine the actions entrepreneurs in an emerging economy adopt to weaken enforcement and normalize rule-breaking activities. We find that entrepreneurs perceive rule-breaking as a way to outsmart the regulatory system and act, both individually and collectively, to discourage authorities from applying penalties for activities deemed noncompliant. We highlight how these actions are inherently destructive, as they sustain enforcement weaknesses in the setting. Our study contributes to the growing literature on rule-breaking and destructive entrepreneurship, offering theoretical implications and policy suggestions aimed at redirecting destructive entrepreneurial behaviors toward more productive ends.<br /
Emotion Regulation During Hostile Interactions : Optimizing Regulation Profiles for Event Performance and Well-Being
No full textInternational audienceWhen employees face hostility from others, emotion regulation is needed to perform effectively but can be personally costly. On the basis of current evidence, employees both perform better and avoid well-being costs with engagement-focused regulation (i.e., modifying feelings through deep acting) rather than with disengagement (i.e., modifying or faking expressions through surface acting). Yet, emotion regulation theorizing suggests this good–bad dichotomy is an oversimplification, and no known work has simultaneously considered the performance and well-being consequences of emotion regulation strategies at the event level. To address these issues, we apply the comprehensive six-strategy emotion regulation framework to identify emergent combinations of regulation strategies used in response to hostile events. Across two studies, we find six emotion regulation profiles, with the pattern of these profiles largely replicating across samples. Study 2 reveals that profile enactment is driven by the intensity of the event and has distinct consequences for employees’ event performance and well-being. We also find the first known evidence of a trade-off, where profiles that result in the highest negative affect were also the most effective for episodic performance. Meanwhile, profiles that maintained low levels of negative affect were linked with lower event performance ratings. Thus, in contrast to the good-bad strategy dichotomy common in the emotion regulation literature, we find that enhancing event performance comes at a cost to affect, and vice versa. This high-hostility work context points to a no-win situation for employees, who must choose between maximizing event performance and minimizing personal costs.<br /
Adolescents and young adults with predominantly low grade primary central nervous system tumors: patient reported socioeconomic outcomes and health-related quality of life ten years after diagnosis
No full textInternational audienceContext: Adolescents and young adults (AYAs) diagnosed with primary central nervous system tumors (PCNST) often face long-term socio-economic challenges and reduced health-related quality of life (HRQoL).Objective: This study aims to evaluate the long-term socio-economic outcomes and HRQoL of AYAs more than ten years after diagnosis.hods: A national, retrospective study conducted between 2019 and 2022, including AYAs aged 15–25 diagnosed with PCNST in 2009–2010, identified through the French Brain Tumor Database. Socio-economic data and HRQoL were assessed using a structured questionnaire and the Short Form-12 (SF-12) Health Survey. Descriptive statistical analyses were performed.Results: Questionnaires were available for 70 patients. Educational level improved over time, but 11.4% still lacked a diploma. While 90% were employed, 45% earned €1500–€2500 per month, and 36.7% earned less than €1500 per month. Workplace accommodations were rarely implemented despite needs. HRQoL assessments showed high physical functioning scores (mean: 85.61), but low vitality scores (mean: 35.82). The mean Physical Component Summary and the mean Mental Component Summary are lower to the general population aged 18–44 in France, respectively 50.6 (SD: 9.1) and 43.6 (SD:12.25) showing a poor physical and a very poor mental HRQoL for AYAs survivors.Discussion: Despite resilience in education and employment, AYAs surviving PCNST face persistent socio-economic difficulties and poor mental HRQoL. Tailored interventions, including increased awareness of support resources and comprehensive care strategies, are needed to improve their long-term outcomes and facilitate better integration into society
Electricity Price Prediction Using Multikernel Gaussian Process Regression Combined With Kernel-Based Support Vector Regression
No full textInternational audienceThis paper presents a new hybrid model for predicting German electricity prices. The algorithm is based on a combination of Gaussian process regression (GPR) and support vector regression (SVR). Although GPR is a competent model for learning sto-chastic patterns within data and for interpolation, its performance for out-of-sample data is not very promising. By choosing a suitable data-dependent covariance function, we enhance the performance of GPR. However, since the out-of-sample prediction is dependent on the training data, the prediction is vulnerable to noise and outliers. To overcome this issue, a separate prediction is calculated using SVR, which applies margin-based optimization. This method is advantageous when dealing with nonlinear processes and outliers, since only certain necessary points (support vectors) in the training data are responsible for regression. The individual predictions are then linearly combined using uniform weights. We evaluate the method on historical German day-ahead prices (2021–2023) and show that it outperforms publicly available benchmarks, namely, the LASSO estimated autore-gressive regression model and the deep neural network benchmark from the recent literature
Pricing for reward-based crowdfunding products under double moral hazard Pricing for reward-based crowdfunding products under double moral hazard
No full textInternational audienceAfter achieving success in reward-based crowdfunding campaigns, many entrepreneurs seek venture capital (VC) funding and retail market entry, conditional on project success (i.e. successful product development and mass production). However, in collaboration with VC investors, crowdfunding pledges can erode retail market revenues by influencing project outcomes due to a double moral hazard problem. Crowdfunding pricing thus becomes a critical mechanism to balance these two payoffs. In this study, we develop a multi-stage game model to address the moral hazard issue between entrepreneurs and VC investors. We derive effort equilibria, revenue-sharing outcomes, and optimal crowdfunding pricing decisions. We also examine VC investor selection criteria and the impact of technology advantage on entrepreneurial profits. Our theoretical findings identify four distinct pricing zones based on VC investor efficiency and the entrepreneur’s technology advantage. The relationship between pricing and technology advantage is shown to depend on VC efficiency. Regarding investor selection, we find that technology advantage is pivotal at low and moderate efficiency levels but becomes irrelevant when efficiency is high. Interestingly, we show that while a substantial technology advantage may harm entrepreneurial profits, it is more likely to benefit entrepreneurs when working with less-efficient investors. Finally, numerical experiments are conducted to validate the theoretical insights, offering practical implications for managing crowdfunding campaigns and VC partnerships
The power of expressed humility: Early stage investors' reaction to humble entrepreneurs
No full textInternational audienceAbstract Research Summary We examine how entrepreneur‐expressed humility affects early stage investors' willingness to fund new ventures. In pitching contexts where investors rely on relational cues and implicit prototypes of entrepreneurs, we theorize three distinct pathways through which expressed humility shapes funding decisions. First, building on research regarding interpersonal signals in early stage valuation, we propose that humility fosters perceptions of interpersonal affect and trust and team‐building qualities, increasing investors' willingness to fund. Second, drawing on implicit leadership theories, we argue that humility may trigger negative perceptions regarding the entrepreneur's ability to make rapid and risky decisions. Across a videometric analysis of 140 real‐world pitches and a randomized experiment with French early stage investors, we show that expressed humility elicits both pathways, but investors prioritize positive attributions. Managerial Summary Although humility is often regarded as a positive leadership trait, it contradicts implicit prototypes of successful entrepreneurs, who are typically seen as dominant and assertive. We examine how early stage investors perceive and respond to displays of humility during pitches. We propose that entrepreneur‐expressed humility produces ambiguous effects: It enhances perceptions of interpersonal affect and trust and team‐building qualities, but raises doubts about the entrepreneur's ability to make rapid and risky decisions. Using a videometric analysis of 140 pitches from the French version of Shark Tank and a randomized experiment with venture capital investors, we find evidence for these competing pathways. Overall, investors prioritize the positive attributions of interpersonal skills, suggesting that entrepreneurs benefit from expressing humility when pitching
Rethinking Corporate Social Responsibility as a Product-Harm Crisis: Explaining the Recent Shift in Terminology from CSR to Sustainability
No full textSince the mid-1920s, scholars and researchers have examined the concept of Corporate Social Responsibility (CSR), which addresses the interaction between business and society. Interest in CSR within the fields of marketing and corporate communication grew significantly after the 1970s, and by the early 2000s, it had become a primary focus of marketing research (Carrigan and Attalla, Journal of Consumer Marketing 18:560–578, 2001). Over the past two decades, a CSR-related concept has begun to emerge within corporate communication: Sustainability. Although its origins can be traced back to the twentieth century, it is only in recent decades, particularly the last 10 years, that the sustainability-related narrative has become majorly significant in shaping the fields of management and business ethics. Despite some overlap between sustainability and CSR concepts, the term “sustainability” has gained increasing prominence in the business sector and public discourse over the past 10 years. While the term “CSR” remains an established and accepted concept in management education and studies, its usage by companies has been declining, with only a few companies today mentioning CSR in their social and environmental reports (known currently as sustainability reports). A few references in management literature mention the shift in corporate communication practice from the concept of CSR to that of sustainability. However, there is currently no theoretical explanation that clarifies why this transition has occurred and why it is important. Therefore, following an analogy-based, theory-building approach, this chapter examines this linguistic transition from CSR to sustainability in corporate communication to provide a theoretical interpretation to this linguistic transition. Our objective is to interpret the reasons behind this shift in the business world and to emphasize the importance of using sustainability-related terminology in academia, which has not yet fully occurred. To develop our analogy, we follow (Cornelissen, Academy of Management Review 30:751–764, 2005) three-phase process of analogical reasoning. In Phase 1, we establish the fundamental correspondence between two relevant domains, drawing parallels between the product-harm crisis from marketing literature and CSR, here conceived as a product. In Phase 2, essential characteristics are transferred from the first domain of the analogy (product-harm crisis) to the second one (CSR). Phase 3 leads to the identification of a new concept: the CSR-harm crisis. This new concept clarifies the inadequacies and potential dangers of persisting with traditional CSR terminology in corporate communication, which may have detrimental implications for both corporations and society at large. This chapter urges scholars in the field to accept the new lexicon to reflect the evolving landscape of the relationship between business and society. The term “corporate sustainability,” or “sustainability,” could indeed broaden the scope of CSR by integrating financial, environmental, and social concerns into the vision of the purpose of a company. The concept is in line with theories which suggest broadening the perspective of organizations’ purpose, responsibility and scope (e.g. Crane et al. 2008; Crane et al., California Management Review 56:130–153, 2014; Scherer and Palazzo, Academy of Management Review 32:1096–1120, 2007;Scherer and Palazzo, Journal of Management Studies 48:899–931, 2011;; Sheehy, J of Bus Ethics 131:625–648, 2015; Wood, International Journal of Management Reviews 12:50–84, 2010), which would require companies to accept their social and environmental responsibilities above any other consideration (Garriga and Melé, J of Bus Ethics 53:51–71, 2004)
