汶川地震灾后重建资金筹集方式探究

汶川大地震给我国造成了巨大损失,尤其使四川面临着经济建设与发展的严峻考验。资金来源对于灾后的重建是关键问题。财政资金、对口支援、国内外援助等资金筹措渠道固然重要,但灾区的未来发展不能光靠扶助。本文在阐述了上述筹资方式的基础上,基于多种筹资方式互补的思想,对灾后资金的特点、优劣势及其灾后重建的适用性进行了再思考,进一步探究灾区筹资方式的多样化与互补性。     

88例食道癌术后胃肠减压的护理干预

目的:探讨食道癌术后胃肠减压的护理。方法:对88例食道癌术后患者胃肠减压期间,给予心理护理等一系列的护理措施。结果:所有患者中85例置管成功,有3例没有成功,成功率为96%,有2例出现了脱落,有1例出现了自行拔出胃管。结论:对患者进行有效的胃肠减压,这是确保手术成功的必要条件,护理工作中要密切观察患者的引流是否通畅,如发现问题要及时进行调整,使患者快捷痊愈。     

WATER BILL ESTIMATION WHEN PRICE IS CRYPTIC: EXPERIENCE FROM WINDHOEK,NAMIBIA

For water policy to be effective, policy makers must know how water users perceive and respond to changes in water prices. However, it is not uncommon for water prices faced by consumers to be unclear. In Windhoek, Namibia, the marginal and average water price is difficult to calculate from the information provided in users' utility bills. This paper applies a hedonic pricing approach to investigate price perceptions of water users in a setting with cryptic price information. Using self‐reported water charges as the dependent variable, the pricing model utilises reported utility characteristics and other factors that may affect perceived price. Low‐income standpipe water users report a weighted average monthly charges of N$24.68, whereas users in high income segments report N$521.34. This reflects differences in service levels, possible subsidies to low‐income users and potential errors in respondents' understanding of their water price. Average price per litre (N$11.78 for the low‐use segment; N$1.89 for the highest segment of Tier 1 water use) tends to be perceived as higher by those with lower water use even though average prices in the relevant range should generally be identical.

An experimental investigation of wage taxation and unemployment in closed and open economies

We investigate experimentally the economic effects of wage taxation to finance unemployment benefits for a closed economy and an international economy. The main findings are the following. (i) There is clear evidence of a vicious circle in the dynamic interaction between the wage tax and unemployment. (ii) Employment is boosted by budget deficits but subsequent tax rate adjustments to balance the budget lead to employment levels substantially lower than theoretically predicted. (iii) A sales risk for producers due to price uncertainty on output markets appears to cause a downward pressure on factor employment. For labor the wage tax exacerbates this adverse effect.     

OPTIMAL TRANSITION DYNAMICS IN THE LEONTIEF TWO‐SECTOR GROWTH MODEL WITH DURABLE CAPITAL: THE CASE OF CAPITAL INTENSIVE CONSUMPTION GOODS*

We present results on undiscounted optimal policies in the Leontief two‐sector growth model with durable capital. Unlike the results with a labour intensive consumption goods sector, we show that a monotonic optimal programme is only one special case out of many richer possibilities of transition dynamics. Depending on the initial capital stock, and a key parameter ζ that could be interpreted as a marginal rate of transformation of capital between today and tomorrow, an optimal programme may converge to a period‐two cycle; and even when it converges to the golden rule stock, it can do so (damped) cyclically or with a “jump”.
