Information transmission between large shareholders and stock volatility

Does information transmission between large shareholders exacerbate stock volatility or reduce stock volatility? In this study, based on the common shareholding data in the Chinese stock market from 2007 to 2017, we establish the shareholder’s coshareholding network, and use the weighted network clustering coefficient to measure the information transmission speed. Moreover, we investigate the impact of information transmission speed on stock volatility. The empirical results show that a nonlinear U-shaped relationship exists between information transmission speed and stock volatility. The findings are robust to the inclusion of other determinants of stock volatility identified in the literature. Finally, we verify the existence of private information interaction in the coshareholding network.     

Redesigning after-sales service: Impact on incumbent product distribution channels

With the growth of multi-channel retailing, many firms that have traditionally relied upon third-party service providers to offer after-sales service (AS) have introduced direct AS channel. While there exist a few studies that examine the effects of adding a direct sales channel on the sales revenue of incumbent channels, there are no studies investigating the effects of adding direct AS channel. This study tries to fill this research gap by exploring cross-channel effects of including AS through the firm's direct brand stores on performance (i.e., revenue, assortment width, and extent of upselling) in both direct and indirect channels. A matched difference-in-difference quasi-experimental design was used to compare the sales outcomes of test and control groups using a five-year longitudinal dataset from a large dual-channel consumer durables firm. Results reveal that providing AS through the firm's direct channel has a positive significant effect on the revenue and upselling in the indirect channel, but no significant impact on assortment width in the indirect channel. However, unlike hypothesized, it results in significantly lower revenue, assortment width, and upselling in the direct channel. We interpret these negative effects as arising from customer confusion and perceived retail crowding. Overall, our research highlights that implementation of going direct with AS should be done with utmost care. Our findings would serve as a building block for future studies that are conducted to understand the dynamic cross-channel effects of introducing direct AS, and would be useful for drawing comparisons and contrasts.

The Effects of Central Banks’ Rate Change Patterns on Financial Market Variables

This study examines whether different patterns of change to the benchmark interest rates of central banks are associated with their contributions to variances in the forecast errors of three financial market variables: the long-term interest rate, the foreign exchange rate, and the stock market index. On average, the central bank’s interest rate accounts for approximately 20% of the variance in each variable. We find that the total range of changes is more important than the frequency of changes. The panel regression shows that the range and frequency of policy rate changes is positively associated with the volatility of long-term interest rates but no association with the volatility of stock prices and exchange rates. These results suggest that small and frequent adjustments of policy rates are desirable for reducing the volatility of interest rates. The panel VAR represents interest rate channel is a more important than exchange rate and stock price channel.     

信托受益权登记背景下的信托产品销售决策变化及影响——基于不同渠道偏好和成本的视角

信托受益权的登记细则出台及国内信托受益权账户系统的上线,对信托产品的销售渠道产生影响。通过模型构建,研究新制度背景下服务水平变化对信托公司销售成本的影响,并推导出直销和代销两种渠道的市场份额会发生变化,信托公司直销的市场份额将增加,由第三方财富公司代销的市场份额将逐步减小。销售渠道的改变会降低信托融资的总成本,从而会对信托业以及整个金融监管模式产生积极影响。     

后危机时代外部冲击对我国工业品价格指数的动态传导及结构特征分析

基于SVAR模型,考量次贷危机前后外部冲击对工业品价格指数的动态影响及结构性传导。结果表明：国际金融危机爆发以来,外部冲击对我国工业品价格指数的影响呈现增强趋势,并且国际大宗商品价格冲击是最重要因素;在结构特征上,外部冲击效应具有不完全性,对生产资料PPI的影响较大,对生活资料PPI的影响较小,显示外部冲击效应的传导具有不完全性,黏滞在生产流通领域不能顺利传导至消费领域。     

The Effectiveness of Unconventional Monetary Policy in Japan

Since the global financial crisis of 2007–2008, central bankers around the world have been forced to abandon conventional monetary policy tools in favor of unconventional policies such as quantitative easing, forward guidance, and even lowering the interest rate paid on bank reserves into negative territory. Japan, which faced a crisis in its banking sector and came up against the theoretical zero lower bound on interest rates nearly a decade earlier, was a pioneer in the use of many of these unconventional policy tools. This article analyzes the effectiveness of Japan’s bold experiment with unconventional monetary policy. Using a panel of bi-annual bank data covering the full universe of Japanese commercial banks over a fifteen-year period, this study analyzes the effectiveness of quantitative easing policy on the bank lending channel of monetary policy transmission. Our findings suggest that Japan’s unconventional monetary policy worked: there is a bank lending channel of monetary policy transmission in Japan. These results are robust to the inclusion of time fixed effects and generalized method of moments analysis.     

Pricing dynamics in US fresh produce channels: new empirical evidence

Despite many valuable contributions, prior research has not completely explained retail pricing behavior. This study employs scanner data for 36 fresh produce items analyzing the relationship between costs of goods sold and retail prices to provide further insight into retail pricing behavior. Implications include: (1) where ‘natural’ variation in produce prices do not already exist from the supplier, retailers appear to introduce the variation themselves, independent from shipping point price; and (2) to the extent that supplier-retailer contracts for fresh produce develop, the resulting stabilizing influence on costs may have the preserve effect of increasing retail price variability to consumers.
