Firm Capabilities, Competition and Industrial Policies in a History-Friendly Model of the Computer Industry

In this paper, we explore some problems that industrial policy faces in industries characterized by dynamic increasing returns on the basis of a 'history friendly model' of the evolution of the computer industry. How does policy affect industry structure over the course of industry evolution? Is the timing of the intervention important? Do policy interventions have indirect and perhaps unintended consequences on different markets at different times? We focus on two sets of policies: antitrust and interventions aiming at supporting the entry of new forms in the industry. The results of our simulations show that, if strong dynamic increasing returns are operative, both through technological capabilities and through customer tendency to stick with a brand, there is little that antitrust and entry policy could have done to avert the rise of a dominant firm in mainframes. On the other hand, if the customer lock in effect had been smaller, either by chance or through policies that discouraged efforts of firms to lock in their customers, the situation might have been somewhat different. In the first place, even in the absence of antitrust or entry encouraging policies, market concentration would have been lower, albeit a dominant firm would emerge anyhow. Second, antitrust and entry encouraging policies would have been more effective in assuring that concentration would decrease. The leading firm would continue to dominate the market, but its relative power would be reduced. © Elsevier Science B.V

Public policies and changing boundaries of firms in a “history-friendly” model of the co-evolution of the computer and semiconductor industries

In this paper, we explore the effects of alternative policies, ranging from antitrust to public procurement, open standards, information diffusion and basic research support on the dynamics of two vertically related industries in changing and uncertain technological and market environments. The two industries are a system industry and a component industry, and the evolution of these industries is characterized by periods of technological revolutions punctuating periods of relative technological stability and smooth technical progress. We have been inspired by the co-evolution of the computer and component industries from their inceptions to the 1980s. On the basis of that evolution, we have developed a history friendly-model this co-evolution. In sum, this paper has stressed that various types of policies may sometimes have contrasting effects on the industry, mainly on concentration and technical change and innovation. It has also shown that the consequences of policies may spillover from one industry to another, and from one type of firms to another. Policies that aim at a specific industry may provoke major changes in a related industry through the product market, the changing boundaries of firms or knowledge and technological interdependencies. The policy maker has to be aware of that. Finally, a major point of the paper regards the unintended consequences of policies

On the Sources and Significance of Interindustry Differences in Technological Opportunities

The set of technological opportunities in a given industry is one of the fundamental determinants of technical advance in that line of business. We examine the concept of technological opportunity and discuss three categories of sources of those opportunities: advances in scientific understanding and technique, technological advances originating in other industries and in other private and governmental institutions, and feedbacks from an industry’s own technological advances. Data from the Yale Survey on Industrial Research and Development are used to measure the strength of various sources of technological opportunity and to discern interindustry differences in the importance of these sources. We find that interindustry differences in the strength and sources of technological opportunities contribute importantly to explanations of cross-industry variation in R&D intensity and technological advance

Appropriating the Returns from Industrial R&D

In this paper, we describe the results of an inquiry into the nature of appropriability conditions in over one hundred manufacturing industries, and we discuss how this information has been and might be used to cast light on important issues in the economics of innovation and public policy. Our data, derived from a survey of high-level R&D executives, are informed opinions about the nature of an industry’s technological and economic environment rather than quantitative measures of inputs and outputs

Capability interactions and adaptation to demand‐side change

Research summaryWe examine how interactions among a firm’s capabilities influence the extent and direction of firm adaptation under conditions of demand‐side change. Our empirical context is the U.S. defense industry, within which we study firms receiving defense‐related Small Business Innovation Research (SBIR) awards around September 11, 2001, an event which constituted an exogenous demand‐side shock in which technology‐related preferences of customers were reshuffled. We find that under demand‐side change, preexisting customer relationships have a double‐edged effect: They facilitate “extension‐based” adaptation when interacted with technology capabilities experiencing a decline in customer preferences, and they hinder “novelty‐based” adaptation when interacted with technology capabilities experiencing an increase in such preferences. We also find that both types of technological capabilities together facilitate adaptation along the extension and novelty paths.Managerial summaryDemand‐side change, in which customer preferences for particular technologies are reshuffled, occurs in many industry settings. A deeper understanding of the factors shaping firm adaptation under this form of change can influence managers’ decisions to implement strategies to plan for and react to such change. Using a sample of firms receiving defense‐related SBIR awards around September 11, 2001, we show that the customer relationships a firm develops prior to demand‐side change can have a double‐edged effect on firm adaptation. Such relationships facilitate “extension‐based” adaptation when combined with technology capabilities declining in customer preferences and hinder “novelty‐based” adaptation when combined with technology capabilities increasing in customer preferences. In addition, the combination of the two technological capability types facilitates adaptation along both paths.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/156170/3/smj3137-sup-0001-Supinfo.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156170/2/smj3137.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156170/1/smj3137_am.pd

Universal Rights and Wrongs

This paper argues for the important role of customers as a source of competitive advantage and firm growth, an issue which has been largely neglected in the resource-based view of the firm. It conceptualizes Penrose’s (1959) notion of an ‘inside track’ and illustrates how in-depth knowledge about established customers combines with joint problem-solving activities and the rapid assimilation of new and previously unexploited skills and resources. It is suggested that the inside track represents a distinct and perhaps underestimated way of generating rents and securing long-term growth. This also implies that the sources of sustainable competitive advantage in important respects can be sought in idiosyncratic interfirm relationships rather than within the firm itself

Lifetime of sub-THz coherent acoustic phonons in a GaAs-AlAs superlattice

We measure the lifetime of the zone-center 340 GHz longitudinal phonon mode in a GaAs-AlAs superlattice excited and probed with femtosecond laser pulses. By comparing measurements conducted at room temperature and liquid nitrogen temperature, we separate the intrinsic (phonon-phonon scattering) and extrinsic contributions to phonon relaxation. The estimated room temperature intrinsic lifetime of 0.95 ns is compared to available calculations and experimental data for bulk GaAs. We conclude that ∼0.3 THz phonons are in the transition zone between Akhiezer and Landau-Rumer regimes of phonon-phonon relaxation at room temperature.United States. Dept. of Energy.
