Order aggressiveness and order book dynamics

In this paper, we study the determinants of order aggressiveness and traders’ order submission strategy in an open limit order book market. Applying an order classification scheme, we model the most aggressive market orders, limit orders as well as cancellations on both sides of the market employing a six-dimensional autoregressive conditional intensity model. Using order book data from the Australian Stock Exchange, we find that market depth, the queued volume, the bid-ask spread, recent volatility, as well as recent changes in both the order flow and the price play an important role in explaining the determinants of order aggressiveness. Overall, our empirical results broadly confirm theoretical predictions on limit order book trading. However, we also find evidence for behavior that can be attributed to particular liquidity and volatility effects.

How credibility affects eWOM reading: The influences of expertise,trustworthiness, and similarity on utilitarian and social functions

In online information settings, a few people tend to contribute, while the majority of people consume. For this latter group of readers, electronic word of mouth (eWOM) provides information about products or service experiences that rarely are available from manufacturer-controlled sources, which makes this source of information especially helpful. In turn, eWOM influences readers' attitudes, intentions, and behavior. Manufacturers also hope to monitor and positively influence eWOM content, such as by supporting and building brand communities. But eWOM readers might doubt the credibility of information if it is mostly positive, and the usefulness of eWOM information depends on its credibility. This study offers an empirical and theoretical validation of how specific utilitarian and social functions of eWOM affect attitudes toward and intentions to read eWOM. In particular, trustworthiness is the most important credibility dimension; it affects both functions. Perceived expertise also enhances the utilitarian while similarity improves the social function of eWOM.

A new wavelet-based ultra-high-frequency analysis of triangular currency arbitrage

We develop a new framework to characterize the dynamics of triangular (three-point) arbitrage in electronic foreign exchange markets. To examine the properties of arbitrage, we propose a wavelet-based regression approach that is robust to estimation errors, measurement bias and persistence. Relying on this wavelet-based (denoising) inference, we consider various liquidity and market risk indicators to predict arbitrage in a unique ultra-high-frequency exchange rate data set. We find strong empirical evidence that limit order book, realized volatility and cross-correlations help forecast triangular arbitrage profits. The estimates are statistically significant and relevant for investors such that on average 80−100 arbitrage opportunities exist with a short duration (100−500 ms) on a daily basis. Our analysis also reveals that triangular arbitrage opportunities are counter-cyclical at ultra-high-frequency levels: arbitrage returns tend to increase (decrease) in periods when volatility risk and correlations are relatively low (high). We show that liquidity-driven microstructure measures, however, appear to be more powerful in exploiting arbitrage profits when compared to market-driven factors.     

产权性质、会计-税收差异与审计收费——来自中国A股上市公司的经验证据

］通过考察注册会计师对审计服务定价时是否考虑会计利润与应纳税所得额之间差异（以下简称“会计-税收差异”）所包含的财务信息,研究发现会计-税收差异与审计收费显著正相关。进一步区分产权性质后发现,对于国有控股上市公司来说,会计-税收差异与审计收费正相关,但这种相关性并不显著;而对于民营上市公司来说,会计-税收差异与审计收费显著正相关。研究结果表明,会计-税收差异会影响注册会计师对审计风险的判断,进而通过增加审计程序来降低审计风险,提高审计收费。且在审计定价时,对于不同产权性质的公司,注册会计师差别对待了会计-税收差异中所包含的信息。     

Do uninformed crossed and internalized trades tap into unexpressed liquidity? The case of Nokia

Crossed and internalized upstairs trades are analysed in a dataset in which institutional investors can be identified. Earlier findings that upstairs trading is uninformed, taps into unexpressed liquidity, and does not affect market quality are revisited. The permanent price effect of crossings and internalized upstairs trades is significantly lower than that of limit order book trades due to the fact that the least informed institutional trades are routed upstairs. Crossed and internalized trades affect the depth and transaction costs in the limit order book and a greater reliance is placed on the upstairs market when liquidity is low and volatility is high.
