Population ageing and inflation with endogenous money creation

This paper models a mechanism through which population ageing may induce a deflationary process. We propose an overlapping-generations model (OLG) with money created by credits (inside money) and intergenerational trade. The model links demographic factors, such as fertility rates and longevity, to prices. We show that lower fertility rates lead to smaller demand for credit and lower money creation, which in turn cause a decline in prices. Changes in longevity affect prices through real savings and the capital market. Furthermore, a few links between interest rates and inflation are addressed; they arise in the general equilibrium and are not thoroughly discussed in literature. Long-run results are derived analytically; short-run dynamics are simulated numerically.     

Decomposing the growth in residential land in the United States

This paper decomposes the growth in land occupied by residences in the United States to give the relative contributions of changing demographics versus changes in residential land per household. Between 1976 and 1992 the amount of residential land in the United States grew 47.7% while population only grew 17.8%. At first glance, this suggest an important role for per-household increases. However, the calculations in this paper show that only 24.5% of the growth in residential land area can be attributed to state-level changes in land per household. 37.3% is due to overall population growth, 22.6% to an increase in the number of households over this period, 6% to the shift of population towards states with larger houses, and the remaining 9.6% to interactions between these changes. There are large differences across states and metropolitan areas in the relative importance of these components.     

Do demand curves for stocks slope down?: Evidence from aggregate data

We examine whether the aggregate demand curve for stocks is downward sloping. As a proxy for aggregate demand, we use net outflows (dividends plus repurchases less net issues) from the stock market scaled by the previous year's market capitalization. To disentangle the information and price pressure effects from the demand curve effects, we use an information-free demographic variable as an instrument and look at the relation between annual changes in aggregate demand and excess market return. We find that information-free changes in the annual aggregate demand for stocks do not lead to changes in the annual excess market return. This finding supports long-term horizontal demand curves for stocks.     

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.     

人口流动性、公共收入与支出--户籍制度变迁动因分析

本文分析了人口流动性的内生决定 ,以此解释中国户籍管理政策变迁的动因。文章表明 ,分权框架下的区际竞争将推动政府降低人口流动成本。一般而言 ,集权 ①框架下的最优流动性水平普遍低于分权框架下的流动性水平。与我国近 2 0年来户籍政策变化相一致的是 ,跨区劳动力配置需求的上升增加了户籍管制的效率损失成本 ,将推动人口流动成本下降。我们认为 ,除了协调地方公共品供给外部性、限制地区间税收竞争以最大化税收收入这两个基本原因之外 ,我国户籍管制的另一个特殊原因是便于执行地区差别政策。而设置流动成本的效率性取决于政府目标与社会福利最大化的一致性程度。     

基于个体为本模型的中国碳排放核算模型构建

为合理测算中国碳排放总量, 提出了以单个人为基础的碳排放核算模型。个体碳排放量受其物质资本与人力资本、消费倾向与投资倾向影响,而计算中国碳排放总量还应考虑人口增长的影响。对个体资本投资倾向提出合理假设,进而构建人口增长模型。最后,根据各省GDP分布情况,赋予模型一个初始财富值,核算出中国碳排放总量。

Within the triangle of healthcare legacies: comparing the performance of South-Eastern European health systems

Objective: Inter-regional comparison of health-reform outcomes in south-eastern Europe (SEE).

Methods: Macro-indicators were obtained from the WHO Health for All Database. Inter-regional comparison among post-Semashko, former Yugoslavia, and prior-1989-free-market SEE economies was conducted.

Results: United Nations Development Program Human Development Index growth was strongest among prior-free-market SEE, followed by former Yugoslavia and post-Semashko. Policy cuts to hospital beds and nursing-staff capacities were highest in post-Semashko. Physician density increased the most in prior-free-market SEE. Length of hospital stay was reduced in most countries; frequency of outpatient visits and inpatient discharges doubled in prior-free-market SEE. Fertility rates fell for one third in Post-Semashko and prior-free-market SEE. Crude death rates slightly decreased in prior-free-market-SEE and post-Semashko, while growing in the former Yugoslavia region. Life expectancy increased by 4 years on average in all regions; prior-free-market SEE achieving the highest longevity. Childhood and maternal mortality rates decreased throughout SEE, while post-Semashko countries recorded the most progress.

Conclusions: Significant differences in healthcare resources and outcomes were observed among three historical health-policy legacies in south-eastern Europe. These different routes towards common goals created a golden opportunity for these economies to learn from each other.     

养老机构发展呼唤创新——基于北京市海淀区养老机构的调研

由于老龄人口剧增,加之社会转型、政府职能转变和家庭养老功能弱化,老年人群,特别是高龄和带病老年人对于社会服务的需求迅速增长,这无疑给现存的养老服务体系带来巨大的冲击和压力。通过对北京市海淀区养老机构长达数月的调研,我们了解到目前入住老人大多身患多种疾病,身体状况普遍较差,大部分老人选择入住养老机构是出于自己的意愿,但是,老人的收入水平限制了其对机构养老方式的选择。通过调研我们还发现,现存养老机构发展面临着资金不足、经营困难以及许多体制性障碍,为促进养老机构发展,在加大投入力度、加快投入步伐、创新投入方式满足社会对养老机构的需求外,应强化保障性养老机构中政府的作用和理顺养老机构的管理体制。此外,由于短时间内,大幅度增加养老机构确有困难,可以规范管理社会化居家养老服务,起到一定的补充、替代作用。     

人口老化的经济分析:近期研究文献述评

本文研究了人口老化的近期文献,发现人口老化可以通过影响要素供给和生产力两大增长源泉影响经济长期增长能力。人口老化会使劳动供给减少,但未必使储蓄率下降(从而资本积累减少)。人口老化会使个体生产力下降,但未必使总生产力下降,对物质资本和人力资本投资的激励增强甚至可以提高生产力。人口老化会增加社会福利支出,进而对国家财政产生压力,但这种压力在不同的社会保障制度下对社会福利影响也有所不同。因此,人口老化并不必然对经济增长具有负效应,我们应对人口老化持谨慎科学的态度。
