We examine how machine learning (ML) predictions of high-growth enterprises (HGEs) help a budget-constrained venture capitalist source investments for a fixed size portfolio. Applying a design science approach, we predict HGEs 3 years ahead and focus on decision (not statistical) errors, using an accuracy measure relevant to the decision-making context. We find that when the ML procedure adheres to the budget constraint and maximizes the accuracy measure, nearly 40% of the HGE predictions are correct. Moreover, ML performs particularly well where it matters in practice—in the upper tail of the distribution of the predicted HGE probabilities. JEL Classification: C53, D22, L25

In this methodological brief, we demonstrate the usefulness of the restricted variance (RV) interaction to entrepreneurship research. RV reasoning can help scholars to specify precise roles for contextual moderators. This specificity allows for strengthening of arguments and for testing of one of the reasons for an interaction. In some cases, it points to otherwise unexpected interaction patterns. We illustrate the power of RV reasoning with a data set of 503 biotech firms to show how RV explains geographic differences in the relationship between number of alliances and initial public offering value. Finally, we show how these interactions can be tested given typical distributions.

Recognizing the importance of various types of artifacts for entrepreneurship, design science (DS) has been proposed as an inclusive approach that combines relevance and rigor. By enabling researchers to go beyond their traditional roles as observers and analysts of established artifacts to help design new artifacts, DS can improve the relevance of entrepreneurship research. However, there is a paucity of knowledge on how this type of research can be published in leading entrepreneurship journals. In this editorial, we seek to provide practical guidance on how to craft and assess DS studies that target Entrepreneurship Theory & Practice (ETP) and other top-tier journals.

This article aims to further the rigor and relevance discussion in entrepreneurship studies. It argues that tensions arise due to an adherence to a rigor-as-correspondence perspective, which can be addressed through the advancement of a rigor-as-performativity perspective. Entrepreneurship concepts are tools used to define, represent, and explain entrepreneurial experience, yet how these tools hook onto the world is a question of performance and application rather than unambiguous correspondence. We advocate for a view of rigor and relevance that appreciates the torch-like features of concepts—how they help entrepreneurs deal with the world so that they may fulfil their intentions—whilst retaining an understanding that the future is unknowable and change a constant.

An emerging body of research has documented that self-employed people are more likely to report higher levels of eudaimonic well-being (EWB; e.g., autonomy, competence, meaning) than their employed counterparts. In this paper, we examine why the self-employed perceive their lives as psychologically more fulfilling even though they face more complex and competing occupational demands that can expose them to more stressors. Specifically, we hypothesize that the self-employed are more likely to engage in problem-focused coping—productive and proactive behaviors and thoughts aimed to help them overcome challenges (e.g., planning and active coping)—and less likely to engage in emotion-focused coping—behaviors and thoughts to merely make them feel better (e.g., venting and denial)—which, in turn, can promote higher levels of EWB. Using data from Waves 2 and 3 of the National Study of Midlife in Development in the United States, we find supportive evidence for our theory. More importantly, we show that the well-being benefits from self-employment accrue almost entirely because the self-employed are more likely to use problem-focused coping as opposed to emotion-focused coping. In a series of robustness tests, including random-effects models, matching estimators, and twin and sibling fixed-effects, we further demonstrate the relevance of coping as a key explanatory mechanism in the relationship between self-employment and EWB.

Research indicates that investors rely on various criteria to evaluate early-stage companies. However, past research in this area has focused on subsets of factors and does not distinguish between the predictors and causal determinants of start-up valuation. In our study, we applied machine learning and causal discovery to analyze a comprehensive dataset with 57 independent variables and 2,366 valuations of start-ups in the United Kingdom. The results show a strong relationship between good predictors and causal determinants of valuation. However, noncausal variables may still be useful for prediction, and inversely, some observed causes may not help in the prediction task.

The enormous scale of suffering, breadth of societal impact, and ongoing uncertainty wrought by the COVID-19 pandemic introduced dynamics seldom examined in the crisis entrepreneurship literature. Previous research indicates that when a crisis causes a failure of public goods, spontaneous citizen ventures often emerge to leverage unique local knowledge to rapidly customize abundant external resources to meet immediate needs. However, as outsiders, emergent citizen groups responding to the dire shortage of personal protective equipment at the onset of COVID-19 lacked local knowledge and legitimacy. In this study, we examine how entrepreneurial citizens mobilized collective resources in attempts to gain acceptance and meet local needs amid the urgency of the pandemic. Through longitudinal case studies of citizen groups connected to makerspaces in four U.S. cities, we study how they adapted to address the resource and legitimacy limitations they encountered. We identify three mechanisms—augmenting, circumventing, and attenuating—that helped transient citizen groups calibrate their resource mobilization based on what they learned over time. We highlight how extreme temporality imposes limits on resourcefulness and legitimation, making it critical for collective entrepreneurs to learn when to work within their limitations rather than try to overcome them.

A critical yet unanswered question for family-owned firms in a survival-threatening crisis is which turnaround moves to employ and for what reasons. Building on noneconomic goals associated with family ownership and related socioemotional wealth (SEW) considerations, we theorize that the higher the degree of family ownership, the more likely family owners are to sacrifice normative SEW dimensions and to protect instrumental SEW dimensions. This then affects which operational, portfolio, financial, and managerial turnaround moves are likely to be employed, and ultimately, the odds of insolvency. Analyzing a unique sample of responses from 209 bank turnaround managers generally confirms our theorizing.

Building on social-psychological insights into social perception and judgment and empirical findings from the entrepreneurship literature, we propose that early-stage equity investors look at two main dimensions to assess entrepreneurs seeking early-stage financing: competence and cooperativeness. In all, 84 angel investors and venture capitalists active in Europe participated in a conjoint experiment. The results show that investors prioritize entrepreneurs’ competence over their cooperativeness. Entrepreneurs’ competence is even more appealing to investors when combined with coachability. We find that entrepreneurs can compensate for a lack of experience by demonstrating solid market knowledge and appearing to be coachable. Furthermore, the results suggest that investors differ in their consideration of entrepreneurs’ cooperativeness, but not competence, when making investment decisions—a finding that is conditional on investors’ usual level of involvement in their portfolio ventures. We discuss these findings from a theoretical and practical perspective.

This article explores why an increasing number of Swedish mothers are becoming entrepreneurs; this choice appears counterintuitive given the prevailing social welfare system prioritizes the rights of employed women. Using an interpretative stance, we analyzed the life stories of 18 Swedish mothers who created new ventures while caring for young children. The value of the time afforded by parental leave policies was identified as vital to the business creation process. Hence, we argue that time is a critical entrepreneurship-relevant resource; this is illustrated by the positive effect of the Swedish welfare system upon entrepreneurship entry and the timing of this decision.
