Despite housing's economic importance, little has been written on how foreclosures and home prices interact in a framework that includes macroeconomic and housing variables such as employment, permits or sales. Panel VAR results for quarterly state‐level data indicate that price–foreclosure linkages run both ways. Foreclosures negatively impact home prices. The negative impact of prices on foreclosures, however, is much larger. These results suggest the low‐frequency association observed between foreclosures and prices is mostly driven by the endogenous adjustment of foreclosures to prices via the strategic choices of homeowners and lenders, rather than through the effects of foreclosures on home prices.  相似文献

This article examines causes of observed stock trading patterns that show high hourly returns and trading volume during early and late trading hours. Using time-stamped data from an institutional investor, we document high levels of portfolio managers' early-morning and late-afternoon decisions to trade that can result in the volume pattern and relatively higher proportions of buy decisions that could contribute to the return pattern.  相似文献

目前我国对绿色生态城区建设的指标体系与评价标准主要关注的还是项目在规划设计阶段的技术目标,虽然评价内容可以分为规划设计评价、实施运管评价两个阶段,但具体的评价体制并未能提供城区在运营阶段的实际碳排放量值的定量评价。要对绿色生态城区在运营阶段对城市整体低碳发展的碳排放减缓贡献有明确的监控方法,必须要建立我国城市绿色生态城区运营阶段温室气体特别是碳排放量的测量、验证与报告(MVR-Monitoring,Verification,Reporting)管理体制。梳理目前有关城市碳排放量度监控方面提出相关的方法,再通过对城区建设管理流程和责任主体的分析,提出一套运营阶段碳排放量测量、验证与报告体制建议。管理体制包括针对我国城区尺度建设项目的 7个排放板块,提出对每个板块的报告主体、核算物理边界、核算周期、核算气体种类、核算运行边界、数据获取方式以及报告指标等要求。同时,为了保障实施,建议明确执行主体层级结构和报告关系,包括对各主体在项目生命周期不同阶段的要求,建立责任约束效应的测量、验证与报告保障制度。  相似文献

This article develops a framework to examine the ex ante benefits of transgenic research on drought in eight low-income countries, including the benefits to producers and consumers from farm income stabilization and the potential magnitude of private sector profits from intellectual property rights (IPRs). The framework employs country-specific agroecological–drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 40% of total benefits across the eight countries. Further, estimated annual benefits of US$178 million to the private sector suggest that significant incentives exist for participation in transgenic drought tolerance research.  相似文献

Referral management for online retailers is a strategically important activity, as referrals offer a highly cost‐effective method of customer acquisition. In fact, online customers mention referrals as the second‐most common reason for choosing to shop at a particular retailer, second only to search engine suggestions. However, while online retailers are able to improve their visibility on search engines through focused keyword insertions, they are often unable to pinpoint the drivers of referral behavior among their customers. The current research examines the relationship between two key dimensions of online retailing: order fulfillment cycle times and referral behavior. Employing a theory of customer appraisal and empirically testing the ensuing model using structural equation modeling, we find that excellent order fulfillment is instrumental in generating referrals for the online retailer, even after factoring in product quality.  相似文献

ABSTRACT

The paper constitutes an analysis of the views of managers of service firms on positioning strategies in Ghana. The research employed a qualitative research method. Data were collected from 21 service managers and analyzed using content analysis procedures. The results indicate that for service managers, the perceived dominant positioning strategies of their organizations were: service quality, customer relationship, innovation, availability of service, community support, and leading organization, among others. The findings suggest that the dominant managerial views of Ghanaian service managers form a ‘hybrid’ of those of the Western manager. This research is important in clarifying this position. Additionally, as an exploratory piece, the study provides bases for further research on a topic in Ghana with a rather scant evidence of research.  相似文献
