The things that belong: a grounded theory study of student categorizations of complex technical artifacts

Technical artifacts play a central role in teaching and learning about technology. The artifact exemplars used in the classroom to illustrate and discuss various technological concepts should therefore be carefully chosen in order to actually support the abstraction and successful transfer of these concepts. Research from the learning and cognitive sciences strongly suggests that this requires an understanding of how students actually perceive and conceptualize various technical artifacts, what similarities, differences and features are most salient and meaningful in their eyes. In this paper, we propose a grounded theory of how students differentiate and relate various complex technical artifacts. The core of our theory is formed by four hierarchically ordered juxtapositions: (1) technology versus non-technology, (2) everyday versus specialized, (3) private versus public, and (4) luxury versus necessity, which divide the realm of technical artifacts into five broad categories: high technology, household technology, public technology, real technology, and no/low technology. Our claim is that these differentiations and categories are generally salient and meaningful for students. Based on the theory of variation, we outline how they might help educators make more informed and systematic selections of exemplar artifacts to use in the classroom.     

Optimum organization of the labor market in a small open economy

In Denmark labor has been organized in independent but cooperating craft unions for more than a century. Within an extremely simple model of a small open economy facing imperfect competition, we analyze four different ways of organizing the labor market and show that the Danish model (partial centralization of the wage setting process) may be accounted for as the outcome of a two-stage Nash bargaining game, being robust in relation to changes in market conditions, and likely close to optimum from the point of view of society as a whole.     

Social preferences and voting: An exploration using a novel preference revealing mechanism

Public referenda are frequently used to determine the provision of public goods. As public programs have distributional consequences, a compelling question is what impact, if any, do social preferences have on voting behavior. This paper explores this issue using laboratory experiments wherein voting outcomes lead to a known distribution of net benefits across participants. Preferences are elicited using a novel Random Price Voting Mechanism (RPVM), which is more efficient in eliciting preferences than a dichotomous choice referendum but gives consistent results. Results suggest that social preferences, in particular a social efficiency motive, lead to economically meaningful deviations from selfish voting choices and increase the likelihood that welfare-enhancing programs are implemented.     

What is Antidumping Policy Really About?

Dumping is whatever you can get the government to act against under the antidumping law. J. Michael Finger (1993, p.viii). Antidumping policy has become one of the most important instruments for protection in the international trade system, but at the same time it is the subject of an intense, though rather chaotic, debate. This paper provides an overview of the antidumping literature and the current issues. First it describes the origins of antidumping policy and provides some basic statistics on its current use drawn from several empirical studies. Next the paper discusses the economic foundations of antidumping law by examining the traditional and modern theories of dumping, as well as the industrial organization literature on price discrimination and predatory pricing. It is demonstrated that those economic foundations are weak. The paper also considers the fairness rationales for antidumping policy. Finally, it addresses the criticisms of antidumping laws, in particular in the context of the current antidumping versus competition policy debate, and discusses a variety of proposals for reform that have been made. The paper shows that the 1997 'cease fire' agreement between Canada and Chile is a promising approach toward reform of antidumping policy.     

Success and Risk Factors in the Pre-Startup Phase

Why does one person actually succeed in starting a business, while a second person gives up? In order to answer this question, a sample of 517 nascent entrepreneurs (people in the process of setting up a business) was followed over a three-year period. After this period, it was established that 195 efforts were successful and that 115 startup efforts were abandoned. Our research focuses on estimating the relative importance of a variety of approaches and variables in explaining pre-startup success. These influences are organized in terms of Gartner’s (Academy of Management Review 10(4), 696–706 [1985]) framework of new venture creation. This framework suggests that start-up efforts differ in terms of the characteristics of the individual(s) who start the venture, the organization that they create, the environment surrounding the new venture, and the process by which the new venture is started. Logistic regression analyses are run for the sample as a whole as well as for subgroups within the sample, namely for those with high ambition vs. low ambition and for those with substantial vs. limited experience. The results point to the importance of perceived risk of the market as a predictor of getting started vs. abandoning the startup effort.
