A Comparison of Approaches for Setting Standards for Technological Products

It is widely believed that setting industry-wide standards of uniformity for technological products hastens their diffusion. In this article, Barry Rosen, Steven Schnaars and David Shani examine whether standards merely make markets less competitive, or whether they promote economic growth through the accelerated diffusion of certain new products. The authors also examine conditions which are most conducive to setting standards and reflect on alternative approaches to achieving technical standards. Finally, they ask who should set industry standards? The article presents opposing arguments for allowing industry to cooperate in the setting of standards and for letting the marketplace be the ultimate arbiter of standards—acting to weed out the weak and promote the strongest technological entry.

Hustle for survival or bustle for revival: Effects of Guanxi orientation and order of entry for China's electronic business ventures

Electronic business ventures (EBVs), startups on Internet platforms, have recently attracted research attention. This study attempts to understand the encompassing mechanism for the superior market performance of EBVs entering China's electronic market with a focus on the effects of two important drivers. The first is Guanxi orientation, which is a strategic factor rooted in Chinese culture. The second is the order of entry or the chosen time of entering a market to gain advantages. We test six hypotheses based on data collected from 155 EBVs established over the past 10 years in China. The results show that EBVs' Guanxi orientation positively influences their market performance and that this effect is mediated by political ties built through Guanxi activities. Although the order of entry effect is not evident for EBVs, Guanxi orientation contributes to market performance to a higher degree for late entrant EBVs than for early follower EBVs. The study's findings offer new insights into the implementation of Guanxi orientation in the fast-growing electronic market in China, an emerging country with a culture distinct from that of the West.

Selection of standards for digital television: The battle for Latin America

This paper analyses the implementation of Terrestrial Digital Technology (TDT) standards in Latin America. The analysis suggests that while some governments have chosen the standard attending to their industrial objectives, others have been influenced by the relevance of network externalities and scale economies and by the political and commercial relationship with their neighbours. The discussion about the technical characteristics of the systems was only relevant in the first years of the process, when the leading countries of the region had still not made their selection. Brazil decided to create its own version of the Japanese ISDB standard in 2006, and in the following years it has persuaded a significant part of the continent to choose it. Another block of countries has adopted the US ATSC standard. The most prominent case is that of Mexico, which has a preferential access to the US market. Only three countries have chosen the European DVB standard, the most widely used standard in the world. Colombia has tried to lead its introduction in the continent, but the results so far have been meagre.
