On resource complementarity among startups, accelerators, and primarily financial investors: a large-scale analysis of sorting and value creation
No full textWe propose a theoretical framework and provide empirical evidence on how resource complementarity or substitutability between entrepreneurs and seed investors drives selection and value creation in the context of high-tech startups. Specifically, we argue that seed investors specialized in training programs - startup accelerators - are the ideal match for entrepreneurial teams equipped with strong technological competencies but lacking business knowledge. On the other hand, when entrepreneurs with extensive business knowledge pair up with accelerators, the value created is typically less. Combining information from Crunchbase and LinkedIn, we provide robust empirical evidence based on the assortative matching of start-ups and investors and the ex-post analysis of joint value creation
Out of the trap: customer switching costs, conversion funnel, and industry profitability
No full textDo lower switching costs reduce industry profitability? While established strategy frameworks predict a drop in prices and profitability following reductions in switching costs, we provide a counterexample in which firms’ business model interacts in unexpected ways with switching costs. Across many industries, firms employ a conversion funnel business model to attract customers with affordable products, generate lock-in, and later encourage them to convert to more advanced and profitable products. We argue that a sudden reduction in switching costs disrupts this conversion funnel, which eventually can increase industrywide prices and profitability. We develop a stylized model to formalize our ideas and provide evidence in support of the predictions, using a difference-in-differences methodology with staggered treatment for a large, global sample of mobile telecommunications operators
Market frictions and competitive positions: lessons from the mobile telecommunications market
No full textThis study explores how multi-segment and single-segment competitive positions within an industry are affected by changes in market frictions. A multi-segment position can create value for customers in the form of flexibility to change between service configurations without the need to switch providers. Customers can start with the basic version of a service, then switch to a more advanced version as their preferences evolve. Such a value creation mechanism is effective only in the presence of high costs of switching from one provider to another. Thus, when switching costs fall, multi-segment firms will experience a larger penalty than single-segment ones.
Out of the trap: Conversion funnel business model, customer switching costs, and industry profitability
No full textResearch Summary: Across many industries, firms employ a conversion funnel business model to attract customers with basic and affordable products, generate lock-in, and then sell them more advanced and expensive products. We argue that this business model, coupled with high customer switching costs, results in a market outcome characterized by aggressive pricing and reduced profits. A sudden reduction in customer switching costs disrupts the conversion funnel and can eventually increase industrywide prices and profitability, an outcome that contradicts conventional wisdom in strategy research. We develop a stylized model to formalize our ideas and provide supportive evidence using a difference-in-differences methodology with staggered treatment for a large, global sample of mobile telecommunications operators. Managerial Summary: Industry changes that lower customer frictions can surprisingly be beneficial for companies. Building on the telecommunications industry, we document how a reduction in customer switching costs following mobile number portability increases the profitability of mobile operators. We explain this finding based on a change in companies' business model. When switching costs are high, companies adopt a funnel business model designed to convert customers from basic to advanced products. While advantageous for a single company, when strategic interactions are accounted for, the diffusion of this business model has a depressive effect on average market prices and profitability. A reduction in customer switching costs breaks the funnel and decouples product pricing decisions that, counterintuitively, can lead to higher industrywide prices and greater profitability

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
