The Dynamics of Location in Home Price

It is well established that house prices are dynamic. It is also axiomatic that location influences such selling prices, motivating our objective of incorporating spatial information in explaining the evolution of house prices over time. In this paper, we propose a rich class of spatio-temporal models under which each property is point referenced and its associated selling price modeled through a collection of temporally indexed spatial processes. Such modeling includes and extends all house price index models currently in the literature, and furthermore permits distinction between the effects of time and location. We study single family residential sales in two distinct submarkets of a metropolitan area and further categorize the data into single- and multiple-transaction observations. We find the spatial component is very important in explaining house price. Moreover, the relative homogeneity of homes within the submarket and the frequency with which homes sell affects the pattern of variation across space and time. Differences between single and repeat sale data are evident. The methodology is applicable to more general capital asset pricing when location is anticipated to be influential.

文章以黔东南地区为例主要针对城镇化水平下人居环境的发展模式及优化策略展开研究。首先建立了AHP模型,按照指标体系构建原则,构建了适合评价黔东南地区宜居性的科学合理的客观评价指标体系,以经济建设、居住环境、生态环境、公共服务等4个方面作为影响因子,用层次分析法得出综合权重以及各个指标所占的权重,根据得分分析影响黔东南地区宜居性的指标,其中影响黔东南地区宜居性的因素主要是经济建设和居住条件,其次是生态环境和公共服务,根据数据分析得出黔东南地区目前存在经济、社会、环境协调系数不高、城镇化水平偏低、自然资源丰富的现状。根据数据分析和从黔东南地区的实际情况提出强化城市基础设施;保护生态环境,合理利用资源;继承历史,构造文化底蕴;加强治安力度,提升宜居性等4种优化策略。     

Financial Imbalance Index as a New Early Warning Indicator： Methods and Applications in the Chinese Economy

Based on the stylized facts of financial crises and systemic risk accumulation, this paper constructs a new financial imbalance index （FII） from the perspective of endogenous financial cycles and assesses its application in China＇s macro-financial analysis. The results show that the FII is not only an effective index to detect financial imbalances in China＇s economic cycles, but is also more accurate than and plays more of a leading role than conventional indicators, such as the consumer price index, the financial conditions index and the purchasing managers indicator. Empirical analysis shows that the FII can be used as an effective indicator to measure systemic financial risk, and can provide policy-makers and market participants with useful information to make appropriate decisions.     

Soft drink prices,sales, body mass index and diabetes: Evidence from a panel of low-, middle- and high-income countries

We take advantage of four different cross-country datasets containing data on 78 countries for the period 1999–2014, in order to assess the relationship of carbonated soft drinks’ sales, as well as their prices, with body mass index (BMI), overweight, obesity and diabetes. Using an ecological study design and multivariate regression longitudinal estimation approaches, we find that carbonated soft drink sales were significantly positively related to BMI, overweight and obesity – but only in the low and lower-middle income countries. This finding was robust to a number of sensitivity and falsification checks. In this sub-sample, an increase in per capita soft drink sales by 1 litre per year was related to an increase of BMI by about 0.009 kg/m² (p < 0.1).. This is a small effect, implying that halving annual consumption per capita in this group of countries would result in a drop of BMI by only about 0.03 kg/m². Although soft drink prices were negatively related to weight-related outcomes in the sample of higher middle income and high income countries, this finding was not robust to falsification checks. The results thus suggest that sales restrictions to steer consumers away from soft drinks could indeed have a beneficial health effects in poorer countries, although the effect magnitude appears to be very small. However, given potential limitations of using ecological research design, results from individual level studies would be required to further ascertain the role of soft drink sales and prices in obesity and diabetes.
