We use a vertical product differentiation model under partial market coverage to study the social welfare optimum and duopoly equilibrium when convex costs of quality provision are either fixed or variable in terms of production. We show the following new results. First, under fixed costs, the social planner charges a uniform price for the single variant that just covers costs of quality provision. Like the duopoly equilibrium, this socially optimal pricing entails a partially uncovered market, but a smaller share of the market is served compared with the duopoly equilibrium. Second, for the variable cost case, it is socially optimal to provide both high‐ and low‐quality variants, but market shares need not be equal. This differs from the result in fully covered markets. Third, in the duopoly equilibrium, the quality spread is too wide under variable costs relative to the social optimum. Under fixed costs, the duopoly produces two variants, but quality is too low relative to the social optimum, which has only one variant. 相似文献

Ethical attitudes in relation to meat purchases were studied among urban and rural consumers in Scotland. All subjects perceived at least some ethical issues in relation to animal production systems, in particular, systems keeping animals in close confinement. Welfare‐friendly production systems were viewed as adding value to a food, but this value was not necessarily realizable to producers if purchases occurred only when foods were on special offer. Statements made by individuals were often contradictory, revealing ambivalence, unresolved value conflicts and a general lack of involvement in the nature of meat production. A number of barriers to the establishment of stable attitudes and behaviours in relation to the ethical treatment of food animals were also identified. A key finding of the study is that individuals can hold two views on animal welfare. On the one hand, they may think as citizens influencing societal standards, and on the other, as consumers at the point of purchase. As citizens, they support the notion of animals being entitled to a good life; as meat consumers, they avoid the cognitive connection with the live animal. This paper explores both the citizen–consumer relationship and purchase strategies used by consumers to resolve value conflicts. Lessons for public and commercial policy are highlighted in the context of the Curry Report (2002) which advocates more effective market segmentation where markets are finely attuned to their customers, with the development of a number of assurance schemes discussed in the article. 相似文献

As a result of Indonesia's decentralization program, local governments have gained significantly more responsibility for service delivery, considerably larger fiscal resources, and much greater authority over the use of those resources than before. The present paper develops a simple budget model to describe and explain the substantial differences in pre‐ and post‐decentralization local government fiscal behavior related to spending, taxing and saving. During the post‐decentralization period special attention is paid to the fiscal behavior of natural resource rich regions. Among other things, the evidence suggests that: post‐decentralization local government spending is partly responsive to increasing needs and partly the subject of elite capture; local government taxation has become more aggressive under decentralization and appears to be mostly driven by local bureaucratic expectations related to routine overhead budgets; and the increased savings of local governments during the post‐decentralization period is determined to a large degree by delayed central government transfer payments. 相似文献

This paper outlines the conditions under which contracting of different types succeeds in the provision of public services to agriculture. It observes that performance contracting has been widely attempted in adjusting countries but generally with little success, since it is demanding of resources, flexibility and motivation in government under conditions where these are scarce. Examples are drawn from agricultural marketing. Given the largely private nature of the services to agriculture currently provided by the state, the long-term reform strategy should be market development. Contracting out and management contracting may have a role in this strategy, particularly in better managed adjusting economies. 相似文献

The fastest growing segment of the hospitality industry is gaming-related business. This industry has experienced record numbers of companies going public, and their stocks are considered favorable long-term investments. Research in the initial public offering (IPO) area suggests that investors acquiring stock at the initial offering price earn large returns. The purpose of this study was to determine if large returns are being experienced for IPOs in the gaming segment of the hospitality industry, and if these large returns were limited to investors who purchased the stock at the initial offer price. There were 14 gaming-related companies selected for the study. The conclusions supported research reporting that the highest returns from IPO investments are made when the stock is purchased at the initial offer price. This study concludes that returns based on the initial offer price were greater than the casino index and the IPO index. When the investor purchased the stock at the first day's closing price, however, returns compared to the two indices were surpassed only after holding the stock for 8 weeks. 相似文献
