In this paper, we analyze housing‐market reactions to the release of previously unpublished information on school quality. Using high‐quality housing data, which precisely bracket the timing of the information shock, we investigate housing‐price dynamics within school‐catchment areas. We find a robust short‐term housing‐market reaction to the publication of school‐quality indicators, suggesting that this information was new to the households, and that households are willing to pay for better schools. The publication effect does not seem to be permanent as prices revert to pre‐publication levels after two to three months. 相似文献

We study rational bubbles in a standard linear asset price model. We first consider a class of bubble processes driven by multiplicative i.i.d. shocks. We show that a bubble process in this class either diverges to infinity with probability one, converges to zero with probability one, or keeps fluctuating forever with probability one, depending on investors' “confidence” in expected bubble growth. We call a bubble process having the last property “recurrent.” We develop sufficient conditions for a bubble process to be recurrent when it is driven by non‐i.i.d. shocks, when the risk‐free interest rate is not constant, and when the process is driven by non‐i.i.d. shocks and the risk‐free interest rate is not constant. In the last case we demonstrate via simulation that there can be a prolonged period in which both the bubble and the interest rate stay close to zero. 相似文献

We estimate the growth elasticity of poverty (GEP) using recently developed non‐parametric panel methods and the most up‐to‐date and extensive poverty data from the World Bank, which exceeds 500 observations in size and represents more than 96 percent of the developing world's population. Unlike previous studies which rely on parametric models, we employ a non‐parametric approach which captures the non‐linearity in the relationship between growth, inequality, and poverty. We find that the growth elasticity of poverty is higher for countries with fairly equal income distributions, and declines in nations with greater income disparities. Moreover, when controlling for differences in estimation technique, we find that the reported values of the GEP in the literature (based on the World Bank's now‐defunct 1993‐PPP based poverty data) are systematically larger in magnitude than estimates based on the latest 2005‐PPP based data. 相似文献

In this study we investigate the external validity of the food insecurity and insufficiency measures—specifically, how these measures correlate with food expenditures—using the December 2003 Food Security Supplement of the Current Population Survey. We focus on a special segment of the population—households with low incomes and low food expenditures. If reports of food problems are based on a lack of food, reports should be nearly ubiquitous at the bottom of the expenditure distribution. We find, however, that this is not the case. We define and scale food expenditures several different ways and find that the reported incidence of food insecurity never rises above one‐half anywhere along the corresponding expenditure distributions, leading to concerns about the external validity of the measure. 相似文献

Abstract This paper studies the normative problem of redistribution between individuals who differ in their lifespans. We discuss aspects related to the objective function and argue that aversion to multiperiod inequality should be taken into account. Then, we study the properties of the social optimum both with full information and with asymmetric information. We highlight the role of aversion to multiperiod inequality and show that it has substantial consequences on the design of Social Security schemes. In particular, we show that for a low (resp. high) aversion to multiperiod inequality, a negative (resp. positive) implicit tax rate on continued activity is desirable. 相似文献

The Association of Southeast Asian Nations (ASEAN) was formed in 1967 for geopolitical reasons, but faced with the competitive threat from the North American Free Trade Agreement and the European Single Market, it embarked in 1992 on the ASEAN Free Trade Area in goods, followed by liberalization of services trade and investment flows. A subsequent competitive threat from the rise of China and India led to the ASEAN Economic Community in 2003, targeted at creating a single market and production base and a competitive region with equitable economic development and integrated with the global economy. The ASEAN Economic Community is not quite a common market as it allows for only freer flows of capital and free flows of skilled labor. ASEAN's economic diversity led to difficulties with implementation and the need to narrow the development gap. ASEAN's dependence on global markets and investors led to the emphasis on open regionalism, support of the World Trade Organization, and free trade agreements with its major trade and investment partners. 相似文献

基于引力模型与0-1规划模型的省域经济区划——以江苏省为例 总被引:3,自引:1,他引:3
借助2008年统计数据,采用主成分法得到江苏各地级城市综合质量指数值;根据运输的时间成本与货币成本,计算江苏地级城市间经济距离;运用引力修正模型计算江苏地级城市间相互引力,并结合0-1规划模型划分经济区;依据经济区内县域间三次产业结构差异度与位置邻近性,划分经济亚区。研究表明:①江苏省可分为宁镇扬泰、苏锡常通、徐连宿、淮盐等4大经济区和15个经济亚区。②各城市连接的地区个数遵循Zipf定律,作为一、二级节点的南京和苏州统领全省经济空间网络,而南通、宿迁、盐城没有显著的联系对象。③江苏经济区空间分布逐渐由南北向格局转为南部呈东西向、北部呈南北向的格局。④各经济区内城市间的引力相差悬殊,南部较大,北部较小。省域尺度的经济区划,可为我国将来划分标准经济区奠定基础,也可为优化全省劳动地域分工格局提供依据。 相似文献

Where imports are financed predominantly by rents from resource extraction or aid the revenue generated by tariffs is illusory. Revenue earned by the tariff is offset by a reduction in the real value of aid and resource rents. Revenue is however moved between accounts in the government budget which, in the case of aid, may reduce the burden of donor conditionality. We demonstrate this proposition for a simple central case and show that the result is not overturned by generalisations around this case. We argue that trade policy formulation in such economies should recognize the illusory nature of tariff revenues. 相似文献

Medicare's prospective payment system for hospitals (PPS), introduced in the USA in 1983, replaced cost reimbursement with a system of fixed rates which created incentives for hospitals to control costs. Previous studies found that elderly patients were discharged from hospital "quicker and sicker" under PPS and concluded that families were coping at home. We analyse a national longitudinal survey, the first National Health and Nutrition Examination Survey and its Epidemiologic Followup Study, which includes data on more outcomes over a longer period than earlier studies. We find that the rate of admission to nursing homes from the community in the first weeks after a hospital discharge more than tripled under PPS, suggesting that families were not always able to cope. As another response to sicker patients, discharges directly to nursing homes from hospitals, which jumped initially under PPS, may have risen further when payment rates were tightened in the early 1990s. Hospital readmissions fell after the first few years. Our findings are strengthened by the fact that we control for patients' health using health information collected independently of hospital admission. 相似文献

This paper presents an axiomatic framework for measuring lifetime poverty over multiple periods. For an individual, we argue that lifetime poverty is influenced by both the “snapshot” poverty of each period and the poverty level of the “permanent” lifetime consumption; it is also influenced by how poverty spells are distributed over the lifetime. We axiomatically characterize classes of lifetime poverty indices and derive dominance conditions of poverty orderings for both individual and societal lifetime poverty measurements. 相似文献
