Competing on the edge: Implications of network position for internationalizing small- and medium-sized enterprises

Three generic competitive strategies attributed to internationalizing SMEs of targeting niches, differentiating products and leveraging networks fail to adequately explain how SMEs win customers in other countries against both large and small competitors. This study distinguishes competitive strategy (how firms compete) from competitive advantage, and from competitive engagements where firms deploy their competitive advantages to win customers within business network relationships. By abductively reasoning from the competitive engagements entered into by the internationalizing SMEs from the Fleet Management Systems industry segment in New Zealand, we show that these firms often compete with foreign rivals by using their position on the edge of a business network to leverage information asymmetries across structural holes. We contribute by integrating this conception of internationalizing SME competitive strategy with the business network foundations of the Uppsala internationalization process model.     

Born globals: A cross-country survey on high-tech start-ups

The paper empirically investigates what drivers affect the decisions of high-tech start-ups to internationalize from the outset, and their degree of born-globalness. The empirical data have been obtained from a cross-country survey on internationalized high-tech start-ups operating in the ICT and electronics sectors. The present findings show that the presence of a small domestic market and the scalability of the product put on sale have a positive effect on the probability of a start-up internationalizing from its inception. We have also observed that the niche strategy and the network relationships built up by the entrepreneur are key drivers for both an early internationalization and the scope of international expansion. The experiential knowledge and international commitment of an entrepreneur, as well as the diversity of team competences and organizational flexibility of a firm, have a significant impact on a born global's degree of born-globalness, although it is not a fundamental precondition for early internationalization.

Born globals – presence,performance and prospects

The concept born global firms has gained a spectacular increase in interest from both academic and political circles. Rigorous quantitative treatment of born global firms are however rare in the international business/economics literature. Implementing unique data on all Swedish start-ups during 1998–2008 in the manufacturing sector, we conclude that born global firms are a very rare event, that their prevalence seems invariant to time, and that they perform similar to other matched “twin” firms with regard to profitability and productivity but report a considerably higher growth in employment and sales. These results are robust to a wider definition of born global firms and to the timing of performance measurements.     

Born internationals: Market expansion and business operation mode strategies in the digital media field

This paper examines leading Swedish and Finnish Internet consultancies operating in the digital media service field. These are ‘born international’ firms that internationalise their business at an exceptionally rapid pace. The paper focuses on why and to what extent the market expansion and business operation mode strategies of these companies deviate from the traditional pattern depicted by the Scandinavian process school. The empirical data consisted of interviews with the founder and senior management and secondary data from company and public archives. The research findings show that in fact both the international new venture research and the Scandinavian internationalisation model appear to be valid. The former model was evidenced by the fact that the born internationals indeed deviated from the behaviour of the traditional firms. The latter was exemplified by the fact that the final internationalisation profile, after the withdrawals of firms from unsuccessful markets, was close to what the Scandinavian internationalisation model would call ‘rational’ expansion. Hence, if the investigation period is long enough to account for unsuccessful endeavours and withdrawals, we may then find empirical support for the traditional model as well. To be reliable, the investigation period should cover at least one economic slow down.     

Context in international business: Entrepreneurial internationalization from a distant small open economy

Context matters in International Business, but to what extent does it influence the content of knowledge? This study offers a systematic literature review on the internationalization of New Zealand firms. A geographically isolated small open economy (SMOPEC) with audacious trade aspirations, a strong domestic institutional environment, favorable attitude toward trade, and entrepreneurial small-to-medium size enterprises (SMEs), New Zealand provides an enlightening context to study internationalization. Using a sample of 95 studies, the review identifies antecedents, stimuli, capabilities, strategy, process and outcomes underpinning internationalizing New Zealand firms (INZFs). Context matters but not in the manner anticipated. On one hand research on the internationalization of New Zealand firms is largely congruent with extant knowledge, on the other the New Zealand context shapes uniquely, how and what scholars choose to research.

Strategic orientations of born globals—Do they really matter?

This paper contributes to the literature on born globals by introducing the concept of strategic orientations into this domain. Only few empirical studies have investigated them in this context. The study extends the existing knowledge on born globals and responds to complaints about lacking empirical research in this as yet infant field. The literature on strategic orientations and born globals was used as a basis for drawing up the hypotheses, which were tested with data from 299 Finnish companies representing several different industrial sectors. The findings indicate that strategic orientations are related to a firm's international performance. This relationship is moderated by its international growth strategy.     

Building and transforming an emerging market global enterprise: Lessons from the Infosys journey

The story of Infosys’ growth and transformation from a $250 start-up to its current market valuation of approximately $26 billion provides one of the most pertinent lessons in leveraging India's strengths and managing the challenges faced by an emerging market global enterprise based in India. In this article, we present a wide-ranging interview with Infosys’ current CEO, Mr. S.D. Shibulal, as he explains what he considers to be the core strengths of the company that made it successful in the past, lays out his vision for the company's future, and discusses in detail how he sees the company's transformation taking place over the coming years. The conversation uncovers several interesting themes and lessons for multinational enterprises in emerging as well as developed economies, including the relevance of being born global, values-based governance, the necessity of creating hybrid business models that infuse the ‘India way’ with local cultures and practices in global markets, leveraging strategic partnerships via co-creation and co-evolution, and the delicate balance between ‘preservation-creation-destruction.’
