Public infrastructure,production organization,and economic development

We develop a political economy model of growth to examine economic development led by the interactions between an economic decision concerning a firm’s production technology (CRS vs. IRS technology) and a political decision concerning public infrastructure. We show that multiple equilibrium growth paths occur due to differences in expectations regarding the quality of public infrastructure. These multiple paths illustrate why economies with poor initial conditions can catch up to and, furthermore, overtake economies with better initial conditions. Our result could explain the experiences of some East Asian countries where the co-evolution of public infrastructure and industrial transformation spurred economic development.     

浅谈我国汽车维修业的未来发展

随着汽车技术的快速发展,日益呈现出汽车维修的高科技特征,与此同时,汽车维修理念也不断更新。汽车维修已不再是简单的零件修复,现代汽车维修是汽车销售、零件销售、资讯及售后服务四位一体紧密结合。汽车维修的新趋势是维修对象的高科技化、维修设备现代化、维修咨询网络化、维修诊断专家化、维修管理电脑化及服务对象的社会化。我国的维修业在发展的道路上面临竞争和挑战,只有在维修业的人力、信息、以及品牌化上加以关注,加强投入。才能适应汽车业发展的新形势。     

The new post-industrial state

With the socioeconomic restructuring of the 1970s and 1980s, the idea of a smooth transition to a post-industrial service economy has required significant revision. We outline three such revisions: the ideas of informatization, informalization, and dualism. The first two are reworkings of post-industrial theory so as to emphasize one or other undervalued trend in industrial society, and are in principle quite compatible. The third emphasizes inequalities in power and resources that are plausibly associated with developments seen as benign by the others. Each has distinct implications for democratic development. However, we argue that while elements of all three models are present in current trends, so that the future might be best seen as a compromise between them, in fact all approaches fail to grasp the real significance of socioeconomic and technological restructuring. A more fruitful approach, with distinctive policy implications, is proposed.     

Ageing and public capital accumulation

We have examined the effects of ageing on the balanced-growth-maximizing public investment policy in an overlapping generations model with growth engines of public capital accumulation. Extended life expectancy tends to increase individual savings, while the increased old-age dependency requires more resources to be allocated to consumption in the economy. Declining working population makes for a severe trade-off between private and public capital accumulation. It is shown that as ageing proceeds, not only the income tax rate must be raised to accelerate public capital formation but the expenditure share of maintenance should be increased in order to maximize the balanced-growth rate.

A Stochastic Overlapping Generations Economy with Inheritance

An overlapping generations model of an exchange economy with two sources of uncertainty is considered. Individuals have a finite expected life span and uncertain annual income. Conditions concerning birth, death, inheritance and bequests are fully specified. Under such conditions, the existence of a stationary Markovian equilibrium is established in some generality, and several explicitly solvable examples are examined in detail.

油价改革——渐进市场化的蜕变

为了解决国际油价高企情况下我国油价倒挂所产生的炼化环节的亏损和迎接2006年底放开成品油批发市场放开外资进入的挑战，我国开展了成品油定价机制改革。虽然市场化是定价机制改革的总方向，但介于我国市场化条件的不成熟，我国应实行逐步实现市场化的方法，同时要注重配套措施的改革，如对弱势群体的补偿，建立公平有效的成品油市场，建设我国的战略石油储备和石油期货市场，我国只有完善了这些软硬件才能真正的实现油价的市场化。
