Press freedom and jumps in stock prices

Press freedom varies substantially across countries. In a free environment, any news immediately becomes public knowledge through mediums including various electronic media and published materials. However, in an unfree environment, (economic) agents would have more discretionary powers to disclose good news immediately, while hiding bad news or releasing bad news slowly. We argue that this discretion affects stock prices and that stock markets in countries with a free press should be better processors of economic information. Using an equilibrium asset-pricing model in an economy under jump diffusion, we decompose the moments of the returns of international stock markets into a diffusive risk and a jump risk part. Using stock market data for a balanced panel of 50 countries, our results suggest that in countries with a free press, the better processing of bad news leads to more frequent negative jumps in stock prices. As a result, stock markets in those countries are characterized by higher volatility, driven by higher jump risk and more negative return asymmetry. The results are robust to the inclusion of various controls for governance and other country- or market-specific characteristics. We interpret these as good stock market characteristics because a free press improves welfare and increases economic growth.     

Impact of growth strategy on mode of governance in alliances

The aim of this study is to analyse the way in which growth strategies influence the choice of governance mode in corporate alliances. Specifically, the study looks at how expansion, diversification and internationalisation strategies determine choice of joint ventures rather than other types of alliances. To that end, we analysed a sample of 918 alliances among companies from the European Union-15 between 2000 and 2004. The results suggest that companies prefer to set up joint ventures when their strategies are based on expansion and related diversification, whereas they prefer other types of alliances when they follow a strategy of unrelated diversification. Furthermore, in international alliances, it appears that the impact of growth strategy on alliance governance mode is similar for the entire range of companies employed in the sample.     

环境不确定下企业孵化网络治理机制对治理绩效影响研究

从企业孵化网络本身以及环境视角分析了企业孵化网络治理绩效的影响因素,通过企业孵化网络治理机制对治理绩效关系的实证分析,验证了环境不确定下企业孵化网络的契约治理机制、管理治理机制对治理绩效的影响。结果表明:企业孵化网络治理机制中的契约治理机制、关系治理机制对治理绩效具有正向调节作用;环境不确定性会扩大或缩小治理机制对治理绩效的作用强度。企业孵化网络在高市场不确定性环境下,采用关系治理机制的绩效较好;在高技术不确定性环境下,采用契约治理机制的绩效较好。     

A two-dimensional problem of revenue maximization

We consider the problem of finding the mechanism that maximizes the revenue of a seller of multiple objects. This problem turns out to be significantly more complex than the case where there is only a single object (which was solved by Myerson, 1981). The analysis is difficult even in the simplest case studied here, where there are two exclusive objects and a single buyer, with valuations uniformly distributed on triangular domains. We show that the optimal mechanisms are piecewise linear with either 2 or 3 pieces, and obtain explicit formulas for most cases of interest.     

Managing the foreign investment portfolio: How industry and governance diversity influence firm performance

Foreign investment has been seen as an important strategy for learning about new technologies and markets. However, the link between the characteristic of a foreign investment portfolio and firm performance has not been examined in detail. Using panel data from 199 Taiwanese firms, this study examines how the foreign investment portfolio in terms of industry and governance diversity influences firm performance. This study finds that governance diversity has an inverse U-shaped relationship to firm performance, whereas industry diversity does not. In addition, this study also finds that their relationships are affected by R&D capability and industry profitability. The empirical findings of our study are useful for firms that invest in emerging economies.     

递增阶梯定价:一个综述

作为较独特的非线性定价,递增阶梯定价使消费者预算凸边界非光滑,进而导致某些消费者消费决策异度集中而难以甄别。此特征致使递增阶梯定价机制的理论和实证研究非常复杂。鉴于公共资源的特殊性,公共资源定价需要合理地兼顾效率、社会公正和成本完全补偿原则。在多元化目标角度上,本文初步验证了递增阶梯定价机制的最优性,虽然此最优性受制于接入率和特征信息等假定。递增阶梯定价下的需求设定趋于统一但估计方法却趋于复杂化和多样化。关于递增阶梯定价下的(价格和收入)需求效应明显与否的问题存在完全相反的结果,实证研究和理论对其不一致性给出多种解释和探讨。这种差异性可能由于消费者对价格、价格设计者对家庭特征等信息不完全,还可能因为各实证分析结果中的时间、市场或产品特征维度含义差异所致。基于多元化目标和资源特性的递增阶梯定价机制的设计和执行问题,将成为递增阶梯定价理论研究发展的一大方向。

银行理财产品收益率市场化演进机制研究——基于修正Hotelling模型的理论分析与实证检验

本文利用修正的Hotelling模型对我国银行理财产品收益率的市场化演进机制进行了理论分析,并使用2005至2019年的银行理财产品历史数据进行了实证检验,得到了一系列结论。第一,收益率落后的“输家”银行下期将以更大的相对幅度提高其收益率,呈现出“输家”追赶“赢家”的锦标赛竞争机制。第二,上述竞争机制受到“输家”银行排名、不同银行之间收益率差距和监管政策的影响。“输家”银行排名越靠后、不同银行之间的收益率差距越大,那么,下期“输家”银行提高其理财产品收益率的相对幅度就越大,不同银行之间的竞争行为就越强烈;与之相对的,监管政策越严,则不同银行之间的竞争强度越弱。本文的研究结论对进一步深入理解我国存款市场化利率的形成机制、加强对商业银行的监管和引导有一定的借鉴和启示意义。
