AN INTEGRATIVE SUMMARY OF DOCTORAL DISSERTATION RESEARCH IN QUALITY MANAGEMENT

Since 1980, practitioner interest in the field of quality management (qm) has grown significantly, resulting in academic researchers embracing QM as a legitimate discipline of study. One approach to evaluating the intellectual health of a discipline is an examination of doctoral dissertation research. This work both complements and extends other published reviews of the quality management discipline by analyzing doctoral dissertation research since 1981, categorizing this research, examining shifts in major research themes, evaluating data collection and analysis methodologies, and discussing general trends in this research area. Our findings suggest that the challenges in QM have become more interdisciplinary and integrated, and reveal an encouraging trend toward more rigorous research methodologies and the increased use of theories from other disciplines, leading to a more mature body of research in this field.     

APPLICATIONS BARRIER TO ENTRY AND EXCLUSIVE VERTICAL CONTRACTS IN PLATFORM MARKETS

Our study extends the empirical literature on whether vertical restraints are anticompetitive. We focus on exclusive contracting in platform markets, which feature indirect network effects and thus are susceptible to an applications barrier to entry. Exclusive contracts in vertical relationships between the platform provider and software supplier can heighten entry barriers. We test these theories in the home video game market. We find that indirect network effects from software on hardware demand are present, and that exclusivity takes market share from rivals, but only when most games are nonexclusive. The marginal exclusive game contributes virtually nothing to console demand. Thus, allowing exclusive vertical contracts in platform markets need not lead to domination by one system protected by a hedge of complementary software. Our investigation suggests that bargaining power enjoyed by the best software providers and the skewed distribution of game revenue prevents the foreclosure of rivals through exclusive contracting.

Mass Migration and the Mass Society: Fordism,Immigration Policy and the Post‐war Long Boom in Canada and Australia, 1947–1970

The immediate post‐war period was defined by shifts in capitalism's socioeconomic and institutional underpinnings. Commonly known as Fordism, until the early‐1970s models of standardized industrial mass‐production and robust state planning and intervention were relatively successful in maintaining secular growth in employment, productivity and demand as well as establishing the national economy and society as unified, governable fields. This paper considers how migration controls in Canada and Australia enhanced and extended such arrangements. In simultaneously boosting production and demand, diversifying and integrating industrial activities and assimilating European migrants into a mass consumer culture while excluding non‐Europeans perceived as disruptive of material and sociocultural homogeneity, such policies provided central vectors of economic and cultural nationalism that complemented other monopolistic and redistributive interventions.     

MONETARY REWARDS AND DECISION COST IN EXPERIMENTAL ECONOMICS

A survey of thirty-one experimental studies which report data on the comparative effects of monetary rewards and opportunity cost shows: (1) several studies in which increased rewards shift the central tendency of the data toward the predictions of rational models; (2) in virtually all cases rewards reduce the variance of the data around the predicted outcome. This is consistent with a model in which rewards are balanced against decision cost in agent behavior and explicates the argument that when rational models fail it can be attributed to low opportunity cost of deviations from the rational prediction.     

Agenda Setting for the Civil Rights Issue

A comparison of front-page New York Times content and nationalpublic opinion from 1954 to 1976 showed strong agenda-settingeffects for the civil rights issue. For this issue, the optimaleffect span was the four- to six-week period immediately priorto field work. These findings contradict previous findings andassertions about a cumulative media effect over a longer periodof time.     

HOUSEHOLDS' GROCERY SHOPPING BEHAVIOR IN THE SHORT-RUN: THEORY AND EVIDENCE

This paper extends the study of nonmarket work activities to explain the impact of household characteristics on grocery shopping behavior. A constrained utility maximization model is developed and the equilibrium conditions of the model are derived. These conditions and the hypotheses implied by them relating to the determinants of time spent in a grocery shopping trip, the size of a purchase, and the number of such trips within a given period of time were tested using data from a sample which identified the household characteristics of grocery shoppers. In these tests, using two-stage least squares, the theoretical implications of our simultaneous equations model are significantly supported.
