The Impact of Dual Agency

In 1984, the State of Hawaii’s legislature enacted a law making it mandatory for real estate agents engaged in dual agency relationships (i.e., when the seller’s and the buyer’s agents are employed by the same real estate firm) to disclose this fact to both parties in writing. The assumption was that the dual agency relation was damaging to the seller. This study analyzes the effect of disclosed and undisclosed dual agency, and the impact of the legislation, using data prior to and after the legislation (approximately 2,000 residential sales in each period). To account for property characteristics, hedonic models for the log of sale price and for the log of days on market are estimated in each period. Our empirical analysis suggests that dual agency significantly reduced the sales price, but the influence was much smaller after the legislation (8.0 versus 1.4%). In addition, dual agency significantly decreased the time on market by approximately 8.5% pre-legislation and 8.1% post-legislation, although the influence was much stronger for lower priced residences. These results are confirmed using a seemingly unrelated regression model.

房地产价格对城镇居民收入差距的影响研究——基于区际差异化市场比较

运用聚类分析方法和五等法计算六大类别不同代表省市的基尼系数,依据2002~2011年省市面板数据考量6个不同类别省市房地产价格对收入差距的影响。结果表明:我国不同类别省市的房价波动对基尼系数的变动呈现出一定的差异性与区域性;第一、三类地区房价波动对城镇居民收入差距产生显著影响;第二类地区房地产市场投资投机活动不如第一、三类城市活跃,房价波动幅度比较稳定;第四、五类地区房价波动对收入差距的影响程度次于第二类地区;第六类地区房价波动幅度小,对收入差距不足以产生显著影响。     

基于均衡分析的我国房地产泡沫度分析

基于均衡分析得到一个检测房地产价格合理性的理论参照,通过将计算出的房地产泡沫度在时间上做纵向对比以及在不同地区间做横向对比,考察现阶段我国房地产泡沫的严重程度。结果表明,现阶段我国大陆总体上的房地产泡沫度与房地产过热阶段的1993年相差不大,与楼市高峰时的香港有不小的差距;我国内地省市的房地产泡沫度一般较低,部分沿海地区接近或超过了楼市高峰时的香港。

投资者关注对金银期货市场收益影响的时频分位研究

根据Google投资者关注度指数和金银期货市场交易数据,构建基于小波分解序列的时频门限自回归分布滞后模型,通过分位数模型参数估计,基于时域与频域联合分析视角,考量投资者关注度对金银期货市场收益的影响。结果表明：投资者关注度对金银期货市场的影响具有异质性;在低频域内,投资者关注度对金银期货市场影响相对较小;极端分位数水平下,投资者关注度对金银期货市场收益影响的时效性较短,投资者关注度对白银期货市场收益的影响较弱。     

结构异质性对中国能源高质量发展的影响研究

基于结构异质性对能源高质量发展影响的理论分析,使用稀疏主成分分析方法测度中国能源高质量发展水平,构建中国和八大经济区域面板分位数回归模型,实证研究了结构异质性对中国能源高质量发展的影响。结果表明：2003—2020年中国能源高质量发展水平有所提升,但仍存在明显的区域发展不平衡问题,西部地区和北部沿海地区的能源高质量发展水平更高。产业结构与能源高质量发展水平呈负相关关系,能源消费结构、资本配置结构与能源高质量发展水平呈正相关关系。     

New evidence on nominal exchange rate predictability

The Meese–Rogoff puzzle, one of the well-known puzzles in international economics, concerns the weak relationship between nominal exchange rates and market fundamentals. The purpose of this paper is to show that market fundamentals do in fact matter in forecasting nominal exchange rates. In particular, we emphasize the importance of the Harrod–Balassa–Samuelson effect in modeling deviations from purchasing power parity. Based on the post-Bretton Woods period, we provide solid out-of-sample evidence that rejects the random walk forecast model at medium-term and long-term forecast horizons. We also find mild evidence for out-of-sample predictability of nominal exchange rates over the short term.
