美国成品油销售市场发展特点与启示

纵观美国成品油销售市场一个多世纪的发展历程,可以总结出以下特点:竞争激烈,行业形成期即埋下竞争的种子;金融创新、技术创新和营销创新齐头并进;油品规格多样,区域间供需不平衡;配送体系高效并富有灵活性;仓储行业竞争激烈,油库数目急剧下降;成品油批发形式多样,炼化企业通过批发价格影响销售;生产、炼油、销售脱离,纵向一体化程度逐渐减弱.借鉴美国的成品油销售行业的发展经验,中国成品油销售企业应加大创新力度,推动营销重心向客户转移;积极营造配送网络,降低成品油输送成本;创新体制机制,使销售成为企业最活跃的一环;采用竞合策略,减少降价对企业的冲击.

Enterprise Unions in the United States

Through a case study of a large industrial company ( TRW ) , this paper examines the history and functioning of independent local unions ( ILUs ). TRW's ILU plant wages were about the same as those at affiliated union plants and higher than those at nonunion plants. The premium explains why TRW and other companies discarded ILUs in favor of a "new" nonunion model. Yet ILUs can remedy some of the defects in that model and thus belong on the policy and research agenda     

Privatizing Highways in the United States

We review the experience of both private toll-roads built in the United States during the 1990s, and argue that the problems they encountered could have been avoided if the length of the franchise contract would adapt to demand realizations. We also argue in favor of adjudicating private toll-roads via BOT-type contracts in competitive (Demsetz) auctions. The lessons of this paper are relevant since growing congestion and troubled government finances have made private toll-roads increasingly attractive in the United States.

Lessons from broadband development in Canada,Japan, Korea and the United States

Broadband network development does not always track closely a nations overall wealth and economic strength. The International Telecommunication Union reported that in 2005 the five top nations for broadband network market penetration were: Korea, Hong Kong, the Netherlands, Denmark and Canada. The ITU ranked the United States sixteenth in broadband penetration.Aside from the obvious geographical and demographic advantages accruing to small nations with large urban populations, broadband development thrives when it becomes a national priority. Both developed and developing nations have stimulated capital expenditures for infrastructure in ways United States public and private sector stakeholders have yet to embrace. Such investments have accrued ample dividends including the lowest broadband access costs in the world. For example, the ITU reports that in 2002 Japanese consumers paid $0.09 per 100 kilobits per second of broadband access compared to $3.53 in the United States.Economic policies do not completely explain why some nations offer faster, better cheaper and more convenient broadband services while other nations do not. This paper will examine best practices in broadband network development with an eye toward determining the optimal mix of legislative, regulatory and investment initiatives. The paper will track development in Canada, Japan and Korea as these nations have achieved success despite significantly different geographical, political and marketplace conditions. The paper also notes the institutional and regulatory policies that have hampered broadband development in the United States.The paper also will examine why incumbent local exchange and cable television operators recently have begun aggressively to pursue broadband market opportunities. The paper will analyze incumbents’ rationales for limited capital investment in broadband with an eye toward determining the credibility of excuses based on regulatory risk and uncertainty. The paper concludes with suggestions how national governments might expedite broadband infrastructure development.
