文章题目Cognitive Reference Points, Left-Digit Effect and Clustering in Housing Markets

文章摘要Using listing data, we document a significant clustering in the house listing and contract prices. Degree of clustering has a direct relation with price levels. Our baseline results indicate that properties listed at smaller left digits, compared to very similar properties that are listed $100 more, are 3.8% more likely to sell, stay on the market 3.5 days (or 5%) shorter and are sold at higher price by $431 (or 0.1%). We run a number of tests to explore the alternative explanations of the estimated effects on sale outcomes besides buyer’s behavioral bias. The results support that buyer factors play a significant role. Finally, using a matched mortgage sample, we find that these buyers are more likely to have a lower credit score and lower income and to be more leveraged on their household balance sheets than those in the control group.

文章题目:宏观审慎监管、房地产市场调控和金融稳定

文章摘要:本文通过构建一个嵌入住房抵押融资摩擦、包含异质性家庭的DSGE模型,运用参数校准和估计,通过模拟分析,考察了模型不同情况下住房需求冲击和杠杆率冲击对经济增长和金融稳定的影响,比较分析了宏观审慎监管框架下贷款价值比(Loan-to-ValueLTV)动态调整规则与静态调整规则的宏观经济和金融稳定效果,以及LTV动态调整规则下“盯信贷”动态规则与“盯房价”动态规则的政策锚选择问题。研究发现,在存在抵押融资摩擦的环境下,相对于纯粹的住房需求冲击而言,住房市场的杠杆率冲击对经济增长和金融稳定的负面影响更大,有必要施加LTV类宏观审慎政策来调控住房市场,维护金融稳定;引入逆周期调节因子的LTV动态调整规则比现行的静态调整规则具有更为显著的金融稳定效果;就防范系统性金融风险而言,“盯信贷”的动态调整规则比直接“盯房价”规则更加占优,而确保该动态规则具有足够的实施弹性,对于增强维持经济金融稳定的效果至关重要。

文章题目Corporate Social Responsibility Spill-over and Synergistic Gains: Evidence from Mergers and Acquisitions

文章摘要Using a large sample of mergers and acquisitions (M&As) in the US, we examine whether and how the difference concerned with corporate social responsibility (CSR) between the acquirer and the target affect both firms’ shareholders. We find that compared with CSR rated deals, referred as the deals with at least one firm being CSR rated, shareholders of target firms respond strongly positively to the deals consisting of high CSR acquirers and low CSR targets or non-rated targets. In particular, this CSR Spillover combination realizes higher immediate announcement returns for target firms and promotes stronger post-merger operating performance for acquirers. We attribute the source of the value creation to the acquirer’s spill-over its CSR practices and experiences to the target. These results are robust to various empirical strategies that address selection bias.

文章题目Number of Siblings, Risk-Sharing, and Financial Risk-Taking: Evidence from China

文章摘要This paper examines the effects of number of siblings on household financial risk-taking in urban China. We find that having more siblings raises the probability of participation in financial markets and the riskiness of household portfolio. We also show that siblings serve as a source of informal financing, a substitute to formal financial institutions. Further, we find that the positive effects of number of siblings on financial risk-taking are more pronounced for individuals with higher income uncertainty, worse health status, more educated siblings and living in the areas with less financial development. Overall, these evidences suggest that risk-sharing within the extended family is a channel through which that the number of siblings affects financial decisions.

文章题目Does the Appreciation of RMB Really Boost Domestic House PricesRegional Evidence from China

文章摘要This paper examines how exchange rate variations affect household welfare from the perspective of regional house prices. Given the consumption and investment attributes of housing, two corresponding mechanisms are proposed, which are the current account channel and the capital account channel. Using Chinese province-level and city-level data, we find that the capital account channel dominates the current account channel and the positive causality between exchange rate and house prices is proved by the DID specification of exchange rate reform in 2005. Moreover, we find that exchange rate movements induce more significant prices’ elevations in housings with higher investment return. Compared with existing researches at more aggregate levels, using regional data generates estimation results more consistent with theory and substantially increases the accuracy of estimated impact.

文章题目How Many Firm Characteristics Drive US Stock Returns?

文章摘要Considering a comprehensive set of 94 firm characteristics, Green, Hand, and Zhang(2017) find that the predictive ability of firm characteristics for US stock returns declines substantially after 2003 and conclude that only two characteristics affect cross sectional value-weighted expected returns since that time. Instead of using conventional ordinary or weighted least squares to estimate high-dimensional linear regressions, which is susceptible to overfitting, we apply a robust forecast combination approach to the cross section of returns. Using machine learning tools to pool forecasts, we find that most of the firm characteristics matter over time and approximately 30 matter on average at a point in time for cross-sectional expected returns both before and after 2003. Our combination approach provides informative and economically significant forecasts of cross-sectional returns before and after 2003.

文章题目Agency Problems of the Controlling Shareholder, Cash Dividends and Dynamic Adjustment of Capital Structure

文章摘要This paper develops a dynamic tradeoff model to describe how agency problems of the controlling shareholder affect the adjustment of capital structure and explore the disciplining effects of cash dividends. The model predicts that agency conflicts increase the adjustment costs, thus slowing down the speed of capital structure adjustment. And the controlling shareholder desires conservative capital structure to mitigate the constraints on expropriating from minority shareholders. However, exogenous cash dividends are negatively related to the agency costs, and thereby influence the capital structure decisions of the corporate. Empirical tests find that the speed of capital structure adjustment is significantly and negatively correlated with the separation of ownership and control but positively correlated with the payout of cash dividends, and this positive correlation is more significant when the agency problems are more serious. Further studies show that, compared with over-levered companies, both the negative impacts of agency costs and the positive impacts of cash dividends on the speed of adjustment are stronger in under-levered companies, and this effect is more significant when agency conflicts are severe.

文章题目Does Mutual Fund Liquidity Matter to Fund Investors? Evidence from an Illiquidity Shock from Stock Trading Halts

文章摘要How do mutual fund investors react to the illiquidity shock on mutual funds' underlying assets? This paper investigates the causal effects of the liquidity of mutual funds' portfolio holdings on fund flows using the illiquidity shock from stock trading halts in Chinese stock market. This unique setting enables us to find an exogenous illiquidity shock that is out of the control mutual funds and mutual fund investors. By looking at the halt status of the top 10 heavily held stocks in actively managed equity funds from 2005 to 2016, We find that fund flows decrease with the extent to which mutual funds suffer from the illiquidity shock. Overall, the results indicate that mutual fund investors react negatively when the liquidity of mutual funds' holdings deteriorates.

文章题目:差异化货币政策调控下影子银行扩张与金融稳定

文章摘要:为了缓解经济的结构性矛盾,我国央行积极运用传统货币政策调控工具,同时创设多种非常规的新型流动性调控方式,以此来支持我国经济的结构性调整和产业升级。而影子银行本身作为信用中介的产物,在这种结构性货币政策的影响下业务模式亦不断推陈出新,其逐利行为带来的系统性风险不断积聚。本文运用分位数脉冲响应模型,详细探讨了我国货币政策、影子银行扩张及金融稳定之间的动态关系。实证结果显示,由于以盯住货币供给为主的传统货币政策传导机制受阻,因此常规货币政策调控方式并不能有效改变影子银行的融资状况和风险承担行为。相反以各类借贷便利类工具为主的非常规货币政策通过影响央行货币的投放方向,以及市场利率的期限分布,使得影子银行业务更多地以通道创新及产品嵌套的高杠杆形式进行扩张,实际形成了资金在同业间“空转”,最终促使系统性风险在体系内快速积聚。为了从根本上缓解影子银行的风险隐患,本文建议应扩大借贷便利工具合格抵押品的范围,缓解货币在银行间市场上不平衡投放的局面,构建“货币政策+宏观审慎政策”双支柱的政策调控框架,引导资金回归服务实体经济的本质。
