Regional wages and market potential in the enlarged EU: an empirical investigation

This article empirically analyses the link between market potential and regional wages in the enlarged EU. We contribute to the existing literature in several ways: (1) we analyse the link between market potential and wages for the EU27 and (2) deconstruct total market potential into several geographical components and analyse their respective contributions to explaining the geographical wage structure. We correct for existing spatial autocorrelation and endogeneity by using an instrumental variable generalized spatial two-stage least squares (IV GS2SLS).     

The impact of international information disclosure requirements on market discipline

Financial regulators are challenged with finding the most efficient and effective ways to monitor banks given an expanding and complex international financial system. Market discipline has grown in importance as a way to discourage banks from taking on unnecessary risk. One of the main drivers of market discipline is information disclosure. While the literature on market discipline is expansive, there are no known studies on the impact of individual information disclosure requirements on market discipline. Our study investigates which specific disclosure requirements influence financial investors to discipline banks and which do not. We find that information disclosure requirements primarily reduce or have no impact on market discipline practices.     

人民币汇率升值:历史回顾、动力机制与前景展望

本文回顾了人民币汇率升值的历史进程,剖析了人民币汇率升值的动力机制,并对人民币汇率升值的前景进行了展望。无论从1994年汇率并轨还是从2005年央行重启汇率改革至今,人民币对美元名义汇率以及人民币有效汇率均经历了显著的升值过程。从利率平价、购买力平价、贸易余额与劳动生产率增速等短、中、长期维度来看,人民币对美元汇率依然存在一定的升值动力。下一阶段人民币对美元汇率走势取决于汇率政策制定过程中的博弈。考虑到贸易顺差、短期国际资本流动、输入性通胀与外部压力等因素的消长,下一阶段人民币对美元汇率的升值幅度有望显著放缓(由之前的年均5%～7%放缓至年均2%～3%),并伴随着人民币对美元汇率波动幅度的明显放大。     

Order imbalance and stock returns: Evidence from China

We investigate the relation between daily order imbalance and return in the Chinese stock markets of Shenzhen and Shanghai. Prior studies have found that daily order imbalance is predictive of subsequent returns. On the two Chinese exchanges we find the autocorrelation in order imbalances is similar to that of the New York Stock Exchange as reported by Chordia and Subrahmanyam [Chordia, T., & Subrahmanyam, A. (2004). Order imbalance and individual stock returns: Theory and evidence. Journal of Financial Economics, 72, 485–518]. We also find a strong contemporaneous relation between daily order imbalances and returns. However, we do not find evidence that order imbalances predict subsequent returns. We attribute the difference in predicative power to differences in trading mechanisms on the two exchanges and to differences in the share turnover rates.

Forecasting Foreign Exchange Markets Using Google Trends: Prediction Performance of Competing Models

Abstract

Foreign exchange markets affect a variety of humans and businesses worldwide and there is a wide array of literature aimed at providing more accurate forecasts of their movement. In an attempt to quantify human expectations, Google query search terms related to foreign exchange markets are used to help explain and predict foreign exchange rates between the United States’ dollar and ten other currencies during the time period of January 2004 and August 2018. We find evidence that, while Google Trends can be helpful in prediction, it is necessary to implement some sort of shrinkage or sparsity scheme on the coefficients.

Market maker competition and price efficiency: Evidence from China

We test the relationship between market maker competition and stock price efficiency. Using the number of market makers as a proxy for competition, the results show a strong positive correlation between competition and stock price efficiency. Moreover, price efficiency is higher when competing market makers have higher research ability. We suggest that market maker competition increases price efficiency through two channels: 1) Competition decreases transaction costs, and 2) Uninformed market makers learn from orders submitted by informed market makers through competition. The latter happens only in the group of market makers with higher experiences. The results imply that the price efficiency can be improved by enhancing the competition of market makers with high research ability and experiences.

股票财富、信号传递与中国城镇居民消费

本文尝试在消费者最优选择模型基础上,通过引入居民的借贷约束和预防性储蓄,推导出能够检验股市的财富效应、信号传递效应和不对称效应的实证分析框架,并利用中国的季度数据考察中国股市变动对居民消费的影响。与国内相关文献所得结论不同,本文的研究表明:如果不仅考虑股票价格变动的财富效应,而且考虑其信号传递效应,那么中国股票市场对城镇居民消费存在着较为明显的影响。分析也表明,如果用工资而不是人均可支配收入度量人力资本回报,中国股票市场同样存在正的财富效应,且这种财富效应具有明显的不对称性,反映经济基本面变化的股价变动对中国居民消费具有长期影响,投机因素引起的股价变动对中国居民消费的影响甚微。
