This paper investigates the long-run relationship among new hiring, unemployment (job seekers), and unfilled vacancies in Japan, using an annual panel data on 47 prefectures for 1972-1999. We find that these three variables are I(1) processes, and are cointegrated in our panel data. Further, we estimate the panel cointegration equation derived from a Cobb-Douglas matching function by the heterogeneous fully modified OLS and heterogeneous dynamic OLS. The estimation results reveal that conventional within estimates could have non-negligible biases.First version received: November 2002/Final version received: October 2003All correspondence to Shigeki Kano.

This paper demonstrates howadditional rents are generated in a fisherycharacterized by intraseasonal variation infish characteristics, including size,condition, and composition. Based on anexpanded conceptual model of the optimalharvest rule, fish characteristics affect preand post harvest production yields and outputprices. A dynamic empirical model, which uses asystem of quality characteristics and anhedonic equation, illustrates the complexrelationships and management choices associatedwith internalizing seafood qualitycharacteristics in a hake fishery. The modelretains the regulated open access managementsystem, but controls intertemporal andintersectoral quotas, production portfolios,and total allowable catch. Results demonstratethat including revenue-side effects frominternalizing fish quality can generatesignificantly greater rents and reduce therelative benefits of increased productionyields. If excluded, bioeconomic models canunderestimate the level of regulatory rentdissipation and overemphasize managementobjectives such as full utilization, whichcould misdirect processing decisions and resultin a suboptimal resource management plan.Implications for data collection,multidisciplinary analysis, and improvements inmarine resource management are discussed.  相似文献

中国经济增长的可能性:一种基于修正的索洛模型的估算   总被引:3,自引:0,他引:3  
郭磊 《当代经济科学》2005,27(3):49-52,110
索洛模型这一经典的经济增长模型有它无可比拟的优点,但对于考察中国问题来说,也有一些内在缺陷.本文根据中国经济增长的特征事实,对索洛模型做出了一些修正,并据此对中国经济增长的可能性进行了重新估算.  相似文献

城市住宅用地空间扩张机制与调控对策   总被引:7,自引:0,他引:7  
刘红萍  杨钢桥 《经济地理》2005,25(1):109-112,116
城市住宅用地空间扩张的必然性与土地资源的稀缺性这一对矛盾,在城市化进程迅速推进的今天显得尤为尖锐,如何实现城市居民居住质量的提高与城市土地资源的可持续利用成为迫切需要解决的问题。文章总结了我国当前城市住宅用地扩张的特点,从经济、制度、技术以及人为干预四个方面对我国当前城市住宅用地空间扩张机制进行了解析,并对城市住宅用地空间扩张过程所出现的问题提出了相关调控措施。  相似文献

临夏模式:形成、发展与转型   总被引:1,自引:0,他引:1  
王必达  赵伟 《经济地理》2005,25(5):698-701
依赖于商贸经济和以皮毛加工为主导产业的临夏模式,未能使临夏实现经济起飞的原因是区际贸易的低水平均衡陷阱把其经济发展限制在了一个狭小的范围。因此,如何通过市场规模的扩展形成需求效应,是临夏这种欠发达民族开放地区实现区域工业化的基本途径。  相似文献

利率模型一直是金融领域的热点。一种新的利率模型——市场模型,其建模原则是由模型得到的标准金融衍生品的定价必须和Black计算的价格相符。笔者认为,市场模型有操作简单方便的优点,这是传统利率模型不具备的,它虽然也有一定缺陷,但仍不失为一种方便使用者的较理想方法。  相似文献

At the turn of 20th century social scientists have built up a large stock of cross-sectional data-sets to study social change. However, scholars more and more collect event history data containing the exact timing of events. Comparing the (dis)advantages event history data are to be preferred. However, for research on value change the event history approach is inapplicable, since it is not possible to ask the timing of a value change retrospectively. I will illustrate that value change (i.e. cohort differences) can be studied adequately with cross-sectional data, if information about the historical context is added. For this purpose I test Inglehart's value change thesis.Interestingly, there are also topics in which cross-sectional data-sets are unnecessarily being used. Using research on secularization as an example, I show that the event-history approach can be used to answer the question whether the decreasing number of religious people concerns a cohort-effect. However, whatever data-set is being used, to study cohort differences, one should always give a theoretical answer to the key-question: what exactly makes cohorts different  相似文献

It is widely known that in practice, different interviewers have different response rates, though there has been no systematic examination of whether this is because of differences among interviewers or differences among those areas allocated to the interviewers (area effects), or both. Furthermore, the conventional wisdom in survey research suggests that it is advisable to have the same interviewers return to the same respondents in order to maintain good response rates in longitudinal surveys, though once again there has been very little documented experimental research to support this. This paper makes use of the interpenetrated sample design experiment in Wave 2 of the British Household Panel Study (BHPS) (i) to explore the effects of interviewers' background characteristics and years of experience on response rates, (ii) to identify and estimate the differential effects of interviewers on response rates and compare the magnitudes of area and interviewer effects, and (iii) to investigate the impact of interviewer continuity. The analysis is facilitated by the use of cross-classified multilevel modelling. The paper also looks at the issue of interviewer continuity qualitatively, through the impressions of the interviewers themselves.  相似文献
