By any measure economists have played increasingly prominent roles in antitrust policy making, at least since the early 1970s. Indeed, the approach to the analysis of public policy toward business pioneered by Chicago school economists dominates the academic literature nowadays. According to the Chicago school's adherents, their insistence that antitrust be examined through the lens of price theory should have produced discernably ‘better’ (read pro-consumer) laws and ‘better’ law enforcement. This paper contends that economists have in fact not had a positive influence on antitrust policy, but have instead actively contributed to its use as a way of subverting competitive market forces.  相似文献

Electricity Market Restructuring: Reforms of Reforms   总被引:5,自引:1,他引:5  
Electricity systems present complicated challenges for public policy. In many respects these challenges are similar to those in other network industries in providing a balance between regulation and markets, public investment and private risk taking, coordination and competition. As with other such industries, naturally monopoly elements interact with potentially competitive services, but electricity has some unusual features that defy simple analogy to other network industries. Following a reversal of a long-term decline in real electricity prices, the last two decades of the twentieth century were for the United States a time of reform, reaction, and reforms of reforms in electricity systems, moving slowly towards greater reliance on competition and markets. Changing technology, new entrants in the generation market, and a legislative mandate to provide access to the essential transmission facility accelerated a process that required major innovations in institutions and operations. Complete laissez faire competition is not possible, and the details of an efficient competitive electricity market are neither obvious nor easy to put in place. The benefits of reform may be substantial, but they require careful attention to market design. A review of the past identifies some choices on the road ahead.  相似文献

Self-classification is used as an a priori approach to tourist typology and market segmentation. However, skepticism still surrounds its ability to incorporate the multidimensionality of tourist behavior. This study seeks to empirically verify the efficacy of a single-item self-classification approach. The robustness of this self-classification measure is examined by comparing it to a data-driven multidimensional psychographic approach in terms of its ability to predict the behaviors of tourists toward food-related destination consumption. Results suggest that the single-item self-classification approach performs equally well as the psychographic approach in segmenting food-related consumption behaviors. The implications and limitations of this study are also discussed.  相似文献
