Moral Agency,Profits and the Firm: Economic Revisions to the Friedman Theorem

The paper reconstructs in economic terms Friedman’s theorem that the only social responsibility of firms is to increase their profits while staying within legal and ethical rules. A model of three levels of moral conduct is attributed to the firm: (1) self-interested engagement in the market process itself, which reflects according to classical and neoclassical economics an ethical ideal; (2) the obeying of the “rules of the game,” largely legal ones; and (3) the creation of ethical capital, which allows moral conduct to enter the market process beyond the rules of the game. Points (1) and (2) position the Friedman theorem in economic terms while point (3) develops an economic revision of the theorem, which was not seen by Friedman. Implications are spelled out for an instrumental stakeholder theory of the firm.

基本公共服务均等化——问题与对策

党的十六届六中全会提出了“完善公共财政制度，逐步实现基本公共服务均等化”的目标，体现了我国政府以人为本、执政为民的理念。然而我国公共服务支出不仅总量偏低，而且在城乡、区域以及财政层级间的分布也不均衡。这主要是由于各地经济发展水平的差异、政府职能转变没有到位、财政管理体制存在缺陷以及政府级次过多等原因所致。为此，本文提出了加快建设公共服务型政府、完善财政管理体制、减少政府层级等措施，以推动基本公共服务均等化的落实。     

The Role of Perceived Product Importance in Organizational Busyer-Seller Relationships

The focus of industrial marketing is shifting toward buyer-seller partnership and greater emphasis is being placed on nurturing these relationships. Partnerships imply intensive ties and complex interaction processes between buyers and sellers. This paper focuses on the affect that perceived product importance has on the complexity of partnership interaction processes. The findings indicate the perceived product importance leads to high levels of cooperation, information exchange and social exchange, in addition to extensive interoranganizational networks involving many functional areas and hierarchical levels. On the other hand, in the industry studied, it did not lead to a mutual commitment of resources. The seller made substantial investments in the relationships with their customers, whereas, in general, the buyers were not perceived as having done so

Analyzing business relationships and distinguishing different interaction levels

Over the years, there have been a large number of attempts to understand relationships in industrial markets. However, even if relationships are built up on the basis of series of interactions, these studies have not offered systematic categorization of different types of relationship interactions. The present article proposes a refined conceptualization for identifying different types of relationship interaction units, labeled interaction levels, ranging from a single exchange to a relationship portfolio. Compared to the current use of two interaction levels in relationship studies, the proposed conceptualization allows a more elaborate analysis of single relationships and better comparisons of different relationships.     

On levies to reduce the nitrogen surplus: The case of Dutch pig farms

Pig farms in the Netherlands pay a zero or low price for using the environment. As a consequence, the environment is overused. The Dutch government wants to reduce the emissions of nitrogen and phosphorus. Possible instruments are regulation and levies. In this study a levy on feed and a levy on the nitrogen surplus are investigated, by incorporating a bad output in the production model. The model is estimated using panel data of Dutch pig farms over the period 1975–1989. Levies on nitrogen turn out to be more cost-effective than levies on feed.
