SEMATECH and collaborative research: Lessons in the design of high-technology consortia

This article reviews the experience of SEMATECH as a model for high-technology research consortia. SEMATECH's original aims of developing next-generation manufacturing technology proved hard to achieve, and the program has refocused on generic technology and the equipment industry infrastructure. Though more modest, these new objectives have produced significant tangible results. The study considers the reasons for the change and implications for consortium design. This is contrasted with the history of other major collaborative research programs in Japan, Europe, and the United States.     

The fragile politics of addiction

Suppose the optimizing consumer only has local information, then what? Obviously, there will be a random element of consumption. The link between the frequency distribution of consumption by person and preference surface is worked out. Under convex preferences there will be a unimodal distribution and conversely. A local optimizing theory of addictive behavior is developed from nonconvex preferences. The resulting bimodal distribution of consumption implies a nonrobust outcome for median voter politics. Such a local optimizing model of addiction is compared with globally optimizing models of addiction.     

Memory for political actors: Contrasting the use of semantic and evaluative organizational strategies

This paper explores the organizational strategies used to represent information about political actors in memory, and it illustrates the usefulness of a specific measure, the adjusted ratio of clustering score (ARC), for inferring memory structure. Assuming the operation of an associative network model, we argue that information about a political actor can be organized along three distinct dimensions: attribute type (differentiating between issue positions and personal attributes), partisanship (differentiating between characteristics typical of Republicans and Democrats), and evaluative type (differentiating between positively and negatively evaluated attributes). The results of a laboratory study indicate that organization along the attribute type dimension was most common, with some evidence of partisan organization. There was no evidence of organization along the evaluative dimension. The implications of the study for understanding individual differences in political reasoning, and the consequences of memory organization strategies, are discussed.     

Urbanization and voter turnout in Korea: An update

In this paper we develop an econometric model to test whether alienation and/or mobilized voting explain urban-rural turnout in Korea. We find that a person's decision to vote is influenced by the act of mobilization and that it affects rural residents more strongly. But we do not find that the feeling of alienation affects a person's decision to vote. Thus, we find support for the mobilized voting hypothesis, but not for the alienation nonvoting hypothesis.     

Risk compensation and the effectiveness of safety belt use laws: a case study of New Jersey

This paper investigates the effectiveness of New Jersey's mandatory belt use law (MUL) by testing specifically for: (1) a safety effect, and (2) a risk-compensation effect that could offset (in part) any safety impact. The main findings are that injury severity declined significantly in the 22 months following implementation of the MUL; but that accident frequency increased significantly. The increase in accidents may be explained only partially by increased driving mileage. These findings suggest that the real safety effect of the law may have been diluted by risk-compensating behavior.This paper is based on a study conducted for the New Jersey Office of Highway Traffic Safety by the Rutgers University Bureau of Economic Research.
