The impact of role models on entrepreneurial intentions and behavior: a review of the literature

Despite the presence of the term ‘entrepreneurial role model’ (ERM) in the discourse on entrepreneurship, existing empirical evidence on the effects of role models is rather limited. By investigating 86 published journal articles, we provide a structured overview of the academic research on role models’ effects on entrepreneurial intentions and behavior. We reveal that prior research focuses particularly on different types of role models (by whom), at which stage of life (when) and in which context the exposure to role models occurs. We use these research areas to structure our review. By expanding the understanding of the current state of ERM research, we reveal research gaps and provide future research recommendations. Our work could help policy makers and educators consider the different types of role models, the sociocultural context and the life cycle stage of the participants in structuring their entrepreneurship education programs.

     

Human Development at Risk: Economic Growth with Pollution-Induced Health Shocks

Risks to human health stemming from polluted air, water, and soil are substantial, especially in the rapidly growing economies. The present paper develops a theoretical framework to study an endogenously growing economy which is subject to pollution-induced health shocks with the health status being an argument of the welfare function. Pollution, arising as a negative externality from production, adversely and randomly affects the regeneration ability of a human body leading to a decline in the overall health status of the population. We include two types of uncertainty surrounding the health status: continuous small-scale fluctuations, driven by the Wiener process, and large-scale shocks or epidemics, driven by the Poisson process. We derive closed-form analytical solutions for the optimal abatement policy and the growth rate of consumption. Devoting a constant fraction of output to emissions abatement delivers the first-best allocation. This fraction is an increasing function of total factor productivity, polluting intensity of production, and damage intensity of both continuous and jump-type shocks. A higher frequency of jumps also calls for more vigorous abatement policies. By contrast, the optimal growth rate of the economy is decreasing in the frequency and intensity of shocks and in the polluting intensity of output. The efficiency of abatement technology has, in general, an ambiguous bearing on both the growth rate and on the abatement share due to the opposing forces of the direct and indirect effects.     

Hazen S. Pingree and the Detroit Model of Urban Reform

Hazen S. Pingree was a remarkable civic leader. In his four terms as mayor of Detroit from 1889 to 1897, Pingree lowered the cost of vital public utilities, including gas, lighting, and transit; modernized the city's sewage system; and rooted out corruption and dishonesty in municipal government. He successfully spearheaded the movement for the three‐cent streetcar fare and brought Detroit to the brink of public ownership and operation of its own transit system. Pingree's social reform program for Detroit centered around two interrelated urban reform movements gathering steam at the turn of the 20^th century: the movement for municipal ownership and the movement to equalize taxes by increasing taxes on corporate property. Both of these movements drew heavily from Henry George's single tax. In particular, Pingree's efforts to secure a municipally owned and operated street railway system and effort to increase taxation on corporate property illustrate the ways in which turn‐of‐the‐20^th‐century civic leaders drew from the rhetoric and substance of George's ideas to implement progressive urban reforms.     

On e-business strategy planning and performance: a comparative study of the UK and Greece

In this research study the effect of Financial and Non-Financial performance of organisations on e-business strategy planning is investigated. The strategic planning parameters of Phillips model are examined when applied to e-business strategy planning. The relationships between these parameters, that is, Formality, Participation, Sophistication and Thoroughness, and Financial and Non-Financial Performance, are examined and the directions of these relationships are investigated. A conceptual model has been constructed and quantitative research methods are used to test four hypotheses. The proposed e-business model was tested in two EU countries, the UK and Greece. A synoptic statistical analysis and comparative numerical results are given showing that in both countries Participation has a positive relationship with Financial Performance and Formality has a positive relationship with Non-Financial Performance. The proposed model is extendable and valid in countries other than the UK and Greece, thus being able to be adapted to and used in other national environments.     

A within-trial cost-effectiveness analysis of panitumumab compared with bevacizumab in the first-line treatment of patients with wild-type RAS metastatic colorectal cancer in the US

Abstract

Aims: This analysis investigated the cost-effectiveness of panitumumab plus mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin) compared with bevacizumab plus mFOLFOX6 in the first-line treatment of patients with wild-type RAS metastatic colorectal cancer (mCRC).

Materials and methods: The cost-effectiveness analysis was developed from a third-party payer perspective in the US and was implemented using a partitioned survival model with health states for first-line treatment (progression-free), disease progression with and without subsequent active treatment, and death. Survival analyses of patients with wild-type RAS mCRC from the PEAK head-to-head clinical trial of panitumumab vs bevacizumab were performed to estimate time in the model health states. Additional data from PEAK informed the amount of each drug consumed, duration of therapy, subsequent therapy use, and toxicities related to mCRC treatment. Literature and US public data sources were used to estimate unit costs associated with treatment and duration of subsequent active therapies. Utility weights were calculated from patient-level data from panitumumab trials in the first-, second-, and third-line settings. A life-time perspective was taken with future costs and outcomes discounted at 3% per annum. Scenario, one-way, and probabilistic sensitivity analyses were performed.

Results: Compared with bevacizumab, the use of panitumumab resulted in an incremental cost of US $60,286, and an incremental quality-adjusted life-year (QALY) of 0.445, translating into a cost per QALY gained of US $135,391 in favor of panitumumab. Results were sensitive to wastage and dose rounding assumptions modeled.

Limitations: Progression-free and overall survival were extrapolated beyond the follow-up of the primary analysis using fitted parametric curves. Costs and quality of life were estimated from multiple and different data sources.

Conclusions: The efficacy of panitumumab in extending progression-free and overall survival and improving quality of life makes it a cost-effective option for first-line treatment of patients with wild-type RAS mCRC compared with bevacizumab.     

Managerial Ownership and Company Performance in German Small and Medium-Sized Private Enterprises

Abstract. We analyse the relationship between managerial ownership and company performance, testing the incentive and entrenchment hypothesis. Differently from previous literature, we focus on small and medium-sized private enterprises which constitute an important part of the German economy. We use a panel of 356 companies in the German business-related service sector for the years 1997–2000. Our findings are that performance, measured by survey-based profit information, is increasing in managerial ownership by up to around 40 per cent. We do not find a significant entrenchment effect, possibly because, at levels at which managers could become entrenched, they already bear a large proportion of the costs and have therefore an incentive to maximize company value.     

Trapped in Informality: The Big Role of Small Firms in Russia’s Statist-patrimonial Capitalism

Manifestations of patrimonialism such as corruption and state predation on business are widespread in many emerging economies. This paper presents the case of Russian political economy, dubbed ‘statist-patrimonial capitalism’, which is marked by state threats to private property rights through bureaucratic extortion or legal harassment. How can we explain the resilience of Russia’s statist-patrimonial capitalism? Predominant accounts focus on the lack of institutional constraints on state predation. The paper offers a different perspective by exploring the often-overlooked contribution of small- and medium-sized enterprises (SMEs). First, statistical data show a steady rise of SMEs in the 2000s despite increasing state predation, suggesting that SMEs are not simply subjugated by the state. Second, in-depth interviews with Russian entrepreneurs reveal that business contributes to the maintenance of the statist-patrimonial system through the mechanism of the ‘informality trap’: firms that choose the informal strategy have difficulties to return to the legal sphere and get stuck in informality. The drivers of informality include firm-specific characteristics, institutional factors and socio-cultural factors dubbed ‘normality’. The mechanism of the ‘informality trap’ highlights the agency of firms in corrupt polities and may be applicable to other emerging economies.

An interactive perspective on business in practice and business in theory

For nearly a quarter of a century researchers engaged in business exchange have met on the annual IMP Conferences to share their experiences, with the phenomenon of interaction and business relationships; its sources, content and effect for the larger business landscape. This special issue’s selection of papers from the 2008 IMP Conference gives a nice illustration of the width and depth in this research. The issue includes considerations of interdependencies in dyadic business relationships, in connected business relationships and among business and non-business organizations. Finally, it includes a discussion of the emergences of research communities like IMP, and stresses the importance of the organically emerging interaction among researchers representing both similar and dissimilar theoretical and empirical interpretations of the dynamics of the business landscape.
