International Comparisons of Australia's Infrastructure Performance

International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.     

How to invest over the life cycle: Insights from theory

We analyse the state of the art in the field of life cycle portfolio choice, a recent strand of the literature on intertemporal portfolio selection. Life cycle models are designed to identify optimal savings and portfolio policies over the lifetime of investors. They can help to improve pension schemes by showing how these could be specifically tailored to the individual employee’s circumstances to overcome the ‘one-size-fits-all’ philosophy still prevailing in parts of the mandatory retirement savings system. To facilitate comparison, we first describe set-up, solution method and characteristic results for a basic model and then derive a general framework to classify existing contributions. We highlight the models’ strengths and weaknesses and assess their ability to resolve existing portfolio puzzles. Lessons from the literature are summarized and promising areas for further research identified. JEL classifications G11, D14, D91, H55

我国国际保理法律机制探究

我国办理国际保理的规模尚小。国际保理业务的一些通行做法与我国国内法律环境“不兼容”是影响其发展的关键因素。笔者在探究了由我国《合同法》确立的商事债权让与制度的基础上,分析以此制度作为我国国际保理的法律规范不能完全适应保理实务和国际惯例的要求。其中对未来发生应收账款债权转让的效力、禁转约定的抗辩、隐蔽性保理在我国法律体系下所遭遇的不适及就应收账转让引起的权利冲突等问题,进行了详细的论述,并提出了相应的立法修正原则。     

Multinational firms, international trade and international telecommunications

The study analyses the determinants of international telephone, telex, telegram and leased lines communication between the United States and 46 countries. It focusses on the role of multinational firms, international trading firms and new information technologies within the framework of the theory of transaction costs.Results of the econometric estimates suggest that: (a) technological conditions of telecommunication infrastructure, i.e., international diffusion lags of new information technologies, play an important role in the explanation of international telephone and telex telecommunication flows but not in the demand for telegraph and leased lines, (b) multinational firms use international telecommunication to reduce the coordination costs and are strong customers of leased lines and telephones, but less so of telex and telegrams, (c) international trading firms exhibit less clear preferences in the use of the different media to reduce transaction costs.     

河北省金融业发展之对策分析
