Optimal market making in the presence of latency

This paper studies optimal market making for large-tick assets in the presence of latency. We consider a random walk model for the asset price and formulate the market maker's optimization problem using Markov Decision Processes (MDP). We characterize the value of an order and show that it plays the role of one-period reward in the MDP model. Based on this characterization, we provide explicit criteria for assessing the profitability of market making when there is latency. Under our model, we show that a market maker can earn a positive expected profit if there are sufficient uninformed market orders hitting the market maker's limit orders compared with the rate of price jumps, and the trading horizon is sufficiently long. In addition, our theoretical and numerical results suggest that latency can be an additional source of risk and latency impacts negatively the performance of market makers.     

Margin trading,short selling,and bond yield spread

Using a quasi-natural experiment, this study examines the effects of margin trading and short selling on bond yield spread in China. It finds that both margin trading and short selling can reduce bond yield spread. Additionally, it finds that margin trading lowers firms’ debt ratios and increases their credit ratings, which explains the reduced spread. In other words, margin trading can impact investors’ decisions by revealing positive information about a firm. Another finding is that short selling lowers the bond yield spread by decreasing earnings management, suggesting that short selling has an impact on investors’ decisions through its effect on corporate governance. Our results suggest that margin trading transmits positive information and short selling impacts firms’ policies. These results provide support for future regulations of margin trading and short selling.     

The impact of customer ratings on consumer choice of fresh produce: A stated preference experiment approach

The importance of customer ratings or reviews in online shopping has been recognized in the previous literature; however, few have studied how online customer rating scores affect consumers’ fresh produce purchases and its importance relative to other fresh produce attributes. The quality of fresh produce demonstrates high uncertainty and variation; therefore, the impact of user-generated content such as customer rating scores on the choice of fresh produce may be more complex than on other product categories. Moreover, previous studies on customer ratings have not examined the price premium that retailers can obtain based on better ratings of fresh produce. Using a stated preference approach (i.e., choice experiment), this study measures the willingness to pay for a higher customer rating score and explores its relative importance to other popular fresh produce attributes (i.e., organic, place of origin, and shelf life). The results show that customer rating is the second most important attribute after the place of origin and is more important than production methods (e.g., organic and naturally grown) for fresh strawberry purchases. Also, rating scores demonstrate a diminishing marginal impact on consumer willingness to pay. Younger consumers and households with children are willing to pay more for fresh produce with high ratings than those with low ratings.

From central planning towards a market economy: The role of ownership and competition in Vietnamese firms’ productivity

This paper examines the role of ownership and market competition in Vietnamese firms’ total factor productivity (TFP) from 2001 to 2011. Making use of a large panel dataset of manufacturing firms, we find that, on average, both foreign-owned enterprises (FOEs) and state-owned enterprises (SOEs) have performed better than privately owned enterprises (POEs) in terms of their TFP levels. However, while FOEs’ TFP ranked the highest in the period 2001–2006, SOEs “closed the gap” in the period 2007–2011. Moreover, we find that market competition has been effective in enhancing average firm productivity and in reducing the gaps in efficiency across ownership types. SOEs’ remarkable performance may be linked to several concurrent factors experienced during the period 2001–2011, namely, the process of restructuring the state sector during the 2000s, the increased economic integration due to the country's accession to the World Trade Organization (2007) and, finally, the preferential access to financial capital and land granted to SOEs. While some evidence supports SOEs’ equitization as an explanation for their remarkable productivity performance, WTO accession and cheaper access to inputs do not fully explain it.

When and why employees of non-profits promote their organizations: Determinants of positive staff-word-of-mouth

Employees represent a credible source of information for prospective job applicants of non-profit organizations. However, less is known about when and why staff actively promote their organizations. The authors develop a parsimonious model of determinants of positive staff-word-of-mouth (SWOM) and test this model on the data from a survey of employees of a major Scandinavian missionary organization (Normisjon). The findings show that identification with the organization, organizational climate, and task satisfaction are significant determinants of positive SWOM. The pattern of effects differs for employees with and without formal leadership responsibility. For employees with such responsibilities, organizational identification has a greater effect and organizational climate a weaker effect on SWOM than for employees with no leadership responsibility. Based on the current findings and the broader literature on employer branding and recruitment, the authors offer tentative guidelines for how to increase positive SWOM for nonprofits.     

Institutional investor sentiment and aggregate stock returns

This paper examines the equity market return predictability of institutional investor sentiment, in comparison to individual investor sentiment. Our findings suggest that institutional traders are informed and that their sentiment helps to tilt stock prices towards the intrinsic value. This is because the sentiment of institutions encompasses news regarding expectations on future cash flows of underlying firms that impounds itself into future price expectations. In this study, we add to the large number of studies that investigate the role and implications of investor sentiment, which has long been viewed as a pure behavioural phenomenon, on market efficiency and price discovery.
