The extent and nature of opportunity identification by experienced entrepreneurs

Guided by insights from cognitive theories, this article explores the links between entrepreneurs' prior business ownership experience and their opportunity identification behavior. Hypotheses were tested using data from 630 entrepreneurs. Experienced entrepreneurs identified more opportunities and exploited more innovative opportunities with greater wealth creation potential. Entrepreneurs that had owned more than 4.5 businesses, however, identified fewer opportunities. The nature of prior business ownership experience also shaped opportunity identification behavior. An inverse U-shaped relationship was detected between the proportion of failed businesses relative to the number of businesses owned and the number of opportunities identified in a given period. Business failure experience was not associated with the innovativeness of exploited opportunities.     

Corporate entrepreneurship: Current research and future directions

In this paper, we suggest future research on the processes and knowledge-based resources in corporate entrepreneurship (CE), argue for the need to appreciate the heterogeneity of CE in relation to new contexts, and suggest appropriate strategies for such contexts. First, we highlight the key contributions of the papers in this special issue, with a particular focus on how they provide insights into structural and process contingencies, the role of management at multiple levels, and organizational and managerial capabilities. We then discuss the limits to the applicability of theories developed in other contexts to CE. Finally, we suggest some future research, with particular emphasis on the corporate governance mechanisms that foster CE and the requisite managerial roles and skills in instigating and supporting entrepreneurial activities at different levels of the organization.     

Fashion creation and diffusion: The institution of marketing

Abstract

In scholarly discussions, marketing tends to be imagined and (re)presented as a practice of organisations, involving a set of activities, whereby consumer desires are discovered and provided for through two-way communication. By studying the creation and diffusion of fashion, we observe that marketing is not simply a mechanism or set of activities but an institution of modern society that involves all social elements together with consumers and marketing organisations. Through a qualitative inquiry with both consumers and producers, we illustrate how these different elements exercise their roles and responsibilities for marketing to work as an institution. By this illustration, we also provide a perspective on how trickle-up, trickle-across, and trickle-down diffusions are simultaneously operative in fashion. Finally, we articulate the implications of recognising marketing as an institution that will help marketing scholars and practitioners in reorganising and re-strategising their purpose and role in society as modernity evolves.     

Decisions,Actions, and Performance: Do Novice,Serial, and Portfolio Entrepreneurs Differ?*

A conceptual framework is extended to take into account differences between inexperienced novice entrepreneurs (that is, individuals with no prior private business ownership experience) and experienced serial and portfolio entrepreneurs. Some policymakers and practitioners are considering whether resources could be more effectively utilized if they were targeted toward serial and portfolio entrepreneurs, rather than in the form of additional initiatives to increase the pool of “pure” nascent entrepreneurs and novice entrepreneurs. To inform this policy debate, similarities and differences between novice, serial, and portfolio entrepreneurs are highlighted with regard to their decisions, actions, performance, and aspirations. We detected that portfolio entrepreneurs were more likely to express dimensions of entrepreneurial behavior. A case for targeted support tailored to the aspirations and needs of novice, serial, and portfolio entrepreneurs is presented.     

A Conceptual Model of Medical Tourism: Implications for Future Research

An extensive review of the current literature reveals that no integrated theoretical framework for the holistic study of the medical tourism industry exists. This study, therefore, aims to fill this gap by proposing an integrated model for the investigation of this burgeoning tourism field. It is developed with a view to capturing the current situation of medical tourism in a given country or region from the supply and demand perspectives. Both qualitative and quantitative techniques are suggested as systematic tools to test and validate the model. This study not only has implications for future research, but also provides useful information for practitioners in the medical tourism industry.     

Information reduction via level crossings in a credit risk model

This paper provides an alternative credit risk model based on information reduction where the market only observes the firm’s asset value when it crosses certain levels, interpreted as changes significant enough for the firm’s management to make a public announcement. For a class of diffusion processes we are able to provide explicit expressions for the firm’s default intensity process and its zero-coupon bond prices.      

Performance evaluation of reverse logistics in food supply chains in a circular economy using system dynamics

Supply chains are composed of multiple stakeholders who have complex interrelationships. In addition, the forward and reverse flow of materials, information, human resources, and finance occurs among different stakeholders in closing the loop of supply chains. Reverse logistics (RL) activities are gaining importance in terms of size and quantity due to both economic and environmental concerns. These flows in RL in supply chains are both dynamic and complex in nature. Further, the environmental impact of RL activities has barely been considered in holistic way in available literature. In this study, a system dynamics model has been developed to analyze and comprehend the green performance of RL activities by predicting the environmental impact of RL activities. The proposed model has been validated by a case study in the context of a food supply chain. In the company where the case study is carried out, the environmental effects of RL activities have been analyzed. These activities in a food supply chain in terms of CO₂ (carbon dioxide), NO_x (nitrogen oxide), SO₂ (sulfur dioxide), and PM (particulate matter) emissions have been predicted through a system dynamics model for the years 2020 to 2024. The proposed methodology is applied in a food supply context, a major player in retail business, especially in emerging economies. According to our findings, the RL activities in a food supply chain can significantly contribute to green performance management by minimizing food waste and loss; hence, the environmental impacts of such activities should be closely examined from a managerial perspective.     

The cost-effectiveness of delayed-release dimethyl fumarate for the treatment of relapsing-remitting multiple sclerosis in Canada

Background: Multiple sclerosis (MS) causes significant disability and diminished quality-of-life. Delayed-release dimethyl fumarate (DMF; also known as gastro-resistant DMF) is a new oral treatment for relapsing-remitting MS (RRMS) approved in the US, Australia, Canada, and Europe. Objectives: A cost-effectiveness model was developed to compare the health economic impact of DMF against other disease-modifying therapies (DMTs) as first-line RRMS treatment from a Canadian Ministry of Health perspective. Methods: A Markov cohort model was developed to simulate patients’ progression through health states based on the Kurtzke Expanded Disability Status Scale (EDSS) over a life-time horizon. Patients entered the model based on a distribution of baseline EDSS scores, from which they could progress to higher or regress to lower EDSS state, or remain in the same state. Relapses could occur at any EDSS score. Results from a mixed-treatment comparison were used to inform model inputs for disease progression and relapse rates per treatment. Costs included direct medical costs stratified by EDSS score. Utilities were accrued based on time spent in each EDSS state. Results: Compared with glatiramer acetate, DMF yielded 0.528 incremental quality-adjusted life-years (QALYs) at an incremental cost of $23 338 Canadian dollars (CAD), resulting in an incremental cost-effectiveness ratio (ICER) of CAD $44 118/QALY. The ICER for DMF compared with Rebif 44?mcg was CAD $10 672. Results were consistent across a wide range of one-way and probabilistic sensitivity analyses. Conclusions: Based on traditional cost-effectiveness thresholds in Canada (CAD $50 000–60 000), DMF can be considered a cost-effective option compared to other first-line DMTs.     

China's Foreign Trade: A “New Normal”

Since the global financial crisis of 2007/2008, China's foreign trade has continued to grow faster than international trade, but its drivers are now different from those prevailing before. The participation of the Chinese economy in the global production chains through processing activities is no longer the main driver of its trade performance. The new driving force of change is ordinary trade, based mainly on local inputs and domestic demand. China, which played a major role in the globalization process as an export base for multinational companies, is now shifting to having a “normal” foreign trade system, which is more closely integrated into the domestic economy.
