Blockchain in Additive Manufacturing and its Impact on Supply Chains

Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results suggest opportunities that are related to intellectual property (IP) rights management, the monitoring of printed parts throughout their lifecycle, process improvements, and data security. The most important barriers for blockchain adoption in AM are an absence of blockchain‐skilled specialists on the labor market, missing governance mechanisms, and a lack of firm‐internal technical expertise. By addressing important limitations of AM, blockchain is expected to improve the competitiveness of AM in parts’ production, catalyzing the trend toward more decentralized manufacturing resulting in more agile, resilient, and flexible supply chains and reduced logistics costs. Beyond that, blockchain‐based AM platforms are expected to enhance supply chain visibility, drive supply chain digitalization, support supply chain finance, and contribute to the emergence of shared factory systems.     

Issues in the estimation and application of latent structure models of choice

Our paper provides a brief review and summary of issues and advances in the use of latent structure and other finite mixture models in the analysis of choice data. Focus is directed to three primary areas: (1) estimation and computational issues, (2) specification and interpretation issues, and (3) future research issues. We comment on what latent structure models have promised, what has been, to date, delivered, and what we should look forward to in the future.     

Technological discontinuities, competition and firm performance

This article discuss in a tentative way what determines the effect of technological discontinuities on the competitive position. of companies within an industry. Three cases of technological change are anahzed: the change from manual to romputer numericalb controlled metal cutting machine tools, the change from stand-alone machine tools to flexible manufacturing systems; and the change from non-cellular to cellular mobile telephony It is argued that the character of technological discontinuity affects market shares, by altering the barriers to entry and mobility, and by being more or less in accordance with the different firms' vision about the future, implying variations in the time needed to detect and accept the new threat or opportunity. A technological discontinuity that includes a new threat or opportunig. A technological discontinuip that involues a new generic technology which substitutes for rather than adds to the previous technology base is seen as being most disruptive. The time actualb available for detecting the need to change and to act is limited by the market growth of the new product (the 'speed of diffusion between users). The faster the difficulties is, therefore diffusion is the greater are the possinbilities that early movers will fain intial advantages. Furthermore, the faster the diffusion is the greater are the possibilities that early movers will build sustanable, volume-related entry and mobility barries.     

External technology acquisition in large multi-technology corporations

Based on different contractual forms and their associated degrees of organizational integration, a typology of strategies for technology acquisition (sourcing) is constructed. Based on a sample of corporations in Europe, Japan and US, it is shown that external acquisition of technology through various strategies increases in importance in general. Product case studies further show that external acquisition of technology is associated with technology diversification into increasingly costly new technologies. As a result corporations become multi-technological ('multech'). At the same time quasi-integrated corporate systems of innovation arise in which in-house R&D is managed together with a mix of strategies for external acquisition of technology, using various contractual forms. This presents new challenges to traditional in-house R&D management. Technology diversification is moreover shown to be associated with growth of sales as well as with growth of R&D expenditures. A high level of external technology acquisition presents risks that ought to lead companies to consider technology based product diversification.     

Consumer Self-Control Strategies: An Empirical Study of Their Structure and Determinants

People use self-control strategies to overcome time-inconsistent preferences. In the present study one aim was to test a two-factor model of consumer self-control strategies that divides them into desire-reducing and willpower strategies. Another aim was to explore what may determine the use of such strategies. Exploratory and confirmatory factor analyses gave support for the two-factor model of self-control. A positive attitude toward risk taking as well as the intention to reduce consumption in response to economic impairment predicted a decrease in the use of both strategies. Financial situation, age, and sex were found to influence the use of desire reduction and willpower in different directions. Income was not a predictor of the use of self-control strategies.     

The competitive solution and the health care problems of today

Mark Pauly claims that a "competitive" health care system will solve the health care cost crisis. This article examines how well the competitive solution deals with the five central problems of the health care system: (1) almost universal lack of adequate health insurance for nursing homes and home care; (2) Medicaid's penurious approach to payment for health services for the poor; (3) the emergence of a dual health care system, especially for children; (4) the entrenched waste and inefficiency of the health care system; and (5) consumers' inability to judge the quality of health care. The competitive solution does not eliminate any of these problems--and may not even improve some of them.     

Immigration and the Trade of Provinces

A link between immigration, imports, and exports has been found by a number of papers that have used the gravity equation to analyze bilateral trade patterns. We discuss what this research implies about the mechanisms through which immigrants expand trade and identify strengths and weakness of the various approaches. This paper also contributes to this literature by estimating immigrant effects for Canada using cross‐province variation in international trade and immigration patterns. We derive an alternative functional form capturing the relationship between immigration and trade based on the proposition that immigrants use their connections and superior 'market intelligence' to exploit trade opportunities that non‐immigrants do not access. We find that the average new immigrant expands exports to his/her native country by $312 and expands imports by $944.     

Value and exchange: Two windows for economic theorizing

This essay introduces a symposium on value and exchange as alternative organizing concepts for the pursuit of economic theorizing. These concepts pertain to two distinct conceptual windows through which economic phenomena can be examined. The immediate inspiration for this symposium was the articulation of Kohn (2004) of the distinction, a distinction that, in turn, was central to the articulation of Buchanan (1964). Furthermore, this distinction is central to the divergent orientations toward economic theorizing that were set forth in the early 1870s by Carl Menger (1971) and Léon Walras (1874).
