Data Quality Affects Meta-Analytic Conclusions: A Response to Miner and Raju (2004) Concerning Entrepreneurial Risk Propensity

A systematic literature review on SME internationalization: a personality lens

The importance of the individual decision-maker within the internationalization process of SMEs has extensively been acknowledged in the International Entrepreneurship field. Yet, despite this, the current discourse is mainly limited to socio-demographics, and social and human capital, and does not seem to advance towards the influence and role of, e.g., deeper-level personality aspects on the SME’s internationalization process. Findings are scattered across different fields of research and disciplines, making it difficult to build upon existing knowledge. To address this, we execute a Systematic Literature Review focusing on internationalization, SMEs, and personality, with specific attention for deeper-level personality aspects. Our findings reveal a rather young body of literature which uses a behavioral perspective, and can be subdivided into three overarching research themes: Internationalization Behaviors, Internationalization Initiation, and Internationalization Performance. Our thematic analysis and cross-thematic discussion provide a fertile ground for further studies on the entrepreneur’s deeper-level personality aspects in relation to SME internationalization. In the future research section, we recommend the exploration of alternative behavioral theories, and multi-level and holistic approaches to further explore this promising sub-domain.

Personality trait differences across types of entrepreneurs: a systematic literature review

The personality traits that define entrepreneurs have been of significant interest to academic research for several decades. However, previous studies have used vastly different definitions of the term “entrepreneur”, meaning their subjects have ranged from rural farmers to tech-industry start-up founders. Consequently, most research has investigated disparate sub-types of entrepreneurs, which may not allow for inferences to be made regarding the general entrepreneurial population. Despite this, studies have frequently extrapolated results from narrow sub-types to entrepreneurs in general. This variation in entrepreneur samples reduces the comparability of empirical studies and calls into question the reviews that pool results without systematic differentiation between sub-types. The present study offers a novel account by differentiating between the definitions of “entrepreneur” used in studies on entrepreneurs’ personality traits. We conduct a systematic literature review across 95 studies from 1985 to 2020. We uncover three main themes across the previous studies. First, previous research applied a wide range of definitions of the term “entrepreneur”. Second, we identify several inconsistent findings across studies, which may at least partially be due to the use of heterogeneous entrepreneur samples. Third, the few studies that distinguished between various types of entrepreneurs revealed differences between them. Our systematic differentiation between entrepreneur sub-types and our research integration offer a novel perspective that has, to date, been widely neglected in academic research. Future research should use clearly defined entrepreneurial samples and conduct more systematic investigations into the differences between entrepreneur sub-types.

The Systematic Impact of Personal Characteristics on Entrepreneurial Intentions of Engineering Students

The impact of personal characteristics on entrepreneurial intention is a classic topic in the field of entrepreneurship research. Previous research mostly used simple linear models, leading to a gap in the study on the interrelationship among personal characteristics and their systematic influence on entrepreneurial intention. This study investigates the interrelationship among the four specific entrepreneurial characteristics (i.e., need for achievement, locus of control, risk-taking propensity, and creativity) and their systematic influence on the entrepreneurial intention of engineering students. The research data is from 210 engineering students via a survey. Logistic regression and path analysis were used for data analysis. The findings suggest that creativity and risk-taking directly influence entrepreneurial intention while the need for achievement and the locus of control influence it indirectly. Implications for entrepreneurship education are finally discussed.

The Influence of Judgment Calls on Meta-Analytic Findings

Previous research has suggested that judgment calls (i.e., methodological choices made in the process of conducting a meta-analysis) have a strong influence on meta-analytic findings and question their robustness. However, prior research applies case study comparison or reanalysis of a few meta-analyses with a focus on a few selected judgment calls. These studies neglect the fact that different judgment calls are related to each other and simultaneously influence the outcomes of a meta-analysis, and that meta-analytic findings can vary due to non-judgment call differences between meta-analyses (e.g., variations of effects over time). The current study analyzes the influence of 13 judgment calls in 176 meta-analyses in marketing research by applying a multivariate, multilevel meta-meta-analysis. The analysis considers simultaneous influences from different judgment calls on meta-analytic effect sizes and controls for alternative explanations based on non-judgment call differences between meta-analyses. The findings suggest that judgment calls have only a minor influence on meta-analytic findings, whereas non-judgment call differences between meta-analyses are more likely to explain differences in meta-analytic findings. The findings support the robustness of meta-analytic results and conclusions.

The Psychology of Entrepreneurship

In this review of the psychology of entrepreneurship, we first present meta-analytic findings showing that personality dimensions, such as (general) self-efficacy and need for achievement, and entrepreneurial orientation are highly associated with entrepreneurship (business creation and business success). We then discuss constructs that were developed within entrepreneurship research, such as entrepreneurial alertness, business planning, financial capital as resources, and entrepreneurial orientation, and how they can be better understood by taking a psychological perspective. Next, we elaborate how traditional psychological constructs have been utilized in entrepreneurship and how this may enhance our knowledge in industrial and organizational psychology (with respect to, for example, knowledge, practical intelligence, cognitive biases, goals and visions, personal initiative, passion, and positive and negative affect). Finally, we provide an overall framework useful for the psychology of entrepreneurship, and implications for future research.

Serum testosterone levels in males are not associated with entrepreneurial behavior in two independent observational studies

Previous research has suggested a positive association between testosterone (T) and entrepreneurial behavior in males. However, this evidence was found in a study with a small sample size and has not been replicated. In the present study, we aimed to verify this association using two large, independent, population-based samples of males. We tested the association of T with entrepreneurial behavior, operationalized as self-employment, using data from the Rotterdam Study (N=587) and the Study of Health in Pomerania (N=1697). Total testosterone (TT) and sex hormone-binding globulin (SHBG) were measured in the serum. Free testosterone (FT), non-SHBG-bound T (non-SHBG-T), and the TT/SHBG ratio were calculated and used as measures of bioactive serum T, in addition to TT adjusted for SHBG. Using logistic regression models, we found no significant associations between any of the serum T measures and self-employment in either of the samples. To our knowledge, this is the first large-scale study on the relationship between serum T and entrepreneurial behavior.

A Meta-Analysis of Interviews and Cognitive Ability

The topic of what interviews measure has received a great deal of attention over the years. One line of research has investigated the relationship between interviews and the construct of cognitive ability. A previous meta-analysis reported an overall corrected correlation of .40 ( Huffcutt, Roth, & McDaniel, 1996 ). A more recent meta-analysis reported a noticeably lower corrected correlation of .27 ( Berry, Sackett, & Landers, 2007 ). After reviewing both meta-analyses, it appears that the two studies posed different research questions. Further, there were a number of coding judgments in Berry et al. that merit review, and there was no moderator analysis for educational versus employment interviews. As a result, we reanalyzed the work by Berry et al. and found a corrected correlation of .42 for employment interviews (.15 higher than Berry et al., a 56% increase). Further, educational interviews were associated with a corrected correlation of .21, supporting their influence as a moderator. We suggest a better estimate of the correlation between employment interviews and cognitive ability is .42, and this takes us “back to the future” in that the better overall estimate of the employment interviews – cognitive ability relationship is roughly .40. This difference has implications for what is being measured by interviews and their incremental validity.

Enhancing Entrepreneurship: The Role of Goal Orientation and Self-Efficacy

Entrepreneurship has become increasingly important in the workplace. Research suggests motivational traits are important in pursuing entrepreneurial activities. Yet, the extent to which factors influencing entrepreneurial versus managerial goals differ remains unclear. This study assessed the influence of goal orientation and self-efficacy in predicting entrepreneurial and managerial career anchors development. Data from 158 college students indicated learning goal orientation (LGO) and performance-prove goal orientation (PPGO) predicted entrepreneurial career anchors when coupled with high self-efficacy. For managerial goals, self-efficacy did not influence these relationships. Findings suggest providing opportunities for increased self-efficacy and adaptive goal orientations may affect entrepreneurial development.

Methodology for Dealing With Duplicate Study Effects in a Meta-Analysis

Study effects developed from the same data set and duplicated in more than one publication likely will bias the aggregated effects in a meta-analysis. This threat to the validity of meta-analyses in organizational research is significant. Methods of detecting overt and covert duplication of publication are presented through an analysis of five published meta-analyses. An unpublished meta-analysis of salesperson turnover is used to present the implications of nonindependence. Options for the correction of duplication are discussed. It is recommended that study effects gathered during the literature search use the proposed screening heuristic to detect and address duplicate study effects.

The big five personality dimensions and entrepreneurial status: a meta-analytical review

In this study, the authors used meta-analytical techniques to examine the relationship between personality and entrepreneurial status. Personality variables used in previous studies were categorized according to the five-factor model of personality. Results indicate significant differences between entrepreneurs and managers on 4 personality dimensions such that entrepreneurs scored higher on Conscientiousness and Openness to Experience and lower on Neuroticism and Agreeableness. No difference was found for Extraversion. Effect sizes for each personality dimension were small, although the multivariate relationship for the full set of personality variables was moderate (R = .37). Considerable heterogeneity existed for all of the personality variables except Agreeableness, suggesting that future research should explore possible moderators of the personality-entrepreneurial status relationship.
