Dual class shares – is India ready for it?

Market evidence suggest that a class of common stock with superior voting rights trades at systematically higher prices than an identical class of stock with inferior voting rights, as control over the firm grants the promoters some opportunity to receive a higher payoff. Differential voting rights class of shares may attract a certain class of investors who are only interested in the economic benefits of a company. It assists management in deterring potential rivals from winning a control and allows raising fresh capital for growth without giving up control. The value of controlling a firm derives from the fact that you believe that you or someone else would operate the firm differently from the way it is being run currently. Differential voting rights shares in different countries have indicated that voting rights are generally worth between 10% and 20% of the value of common stock. This article intends to create awareness about differential voting rights shares, to study the international as well as domestic experience and tries to examine the various factors that affect differential voting rights share prices.     

Conflicts of interest and agent heterogeneity in buyer brokerage

This article investigates the incentives of agents working with buyers (buying agents) under the fixed percentage commission system and the implications on housing market outcomes. Our model shows that the absence of a binding contract creates a risk of losing clients for buying agents, which helps mitigate the conflict of interest between buying agents and their clients. Both the buying agent's prediction accuracy regarding their client's reservation prices and the level of tolerance given by the buyer to the buying agent affect the binding force. Results from simulations and empirical analyses using house transactions in Canada support our model predictions.     

Restricted access: Real estate agent response to client race,ethnicity, gender,and side of market

We design and implement a correspondence experiment to test for differences in real estate agent response across client race, ethnicity, gender, and side of market. Real estate agents are more likely to respond to White clients than Black or Hispanic clients—Whites have a 32.18% higher response rate than Hispanics and an 8.48% higher response rate than Black clients. We also find that real estate agents are more responsive to sellers (23.81% premium over buyers) and female clients (13.57% premium over males).     

具有自营平台的制造商与零售商的竞争与合作模型

本文研究了由1个制造商和1个零售商组成的供应链中的竞争与合作定价问题,其中制造商具有平台直销渠道。本文建立了竞争下的Stackelberg博弈模型,并分析了解的唯一性和合理性,然后给出合作定价模型和各渠道的定价策略,结果表明制造商和零售商最优策略是降低线下渠道销售价格而线上平台销售价格不变。通过对比表明供应链合作所增加的收益等于非合作下零售商的收益,并证明了顾客对线下渠道购买偏好越高,合作所增加的收益越大。进一步地,分析了在合作的情况下制造商是否放弃通过平台直销渠道销售商品的问题,并给出双渠道下供应链总利润比单渠道下总利润高的判定条件。最后给出一个算例,对所获得的结论进行验证和补充。     

Tick size and market quality: Simulations based on agent‐based artificial stock markets

This paper investigates the way that minimum tick size affects market quality based on an agent‐based artificial stock market. Our results indicate that stepwise and combination systems can promote market quality in certain aspects, compared with a uniform system. A minimal combination system performed the best to improve market quality. This is the first study to analyse tick size systems that remain at the theory stage and compare four types of system under the same experimental environment. The results suggests that a minimal combination system could be considered a new direction for market policy reform to improve market quality.     

COMPETITION AND CASCADES IN MARKETS: AN AGENT‐BASED MODEL OF ENDOGENOUS MERGERS

We present an agent‐based model of endogenous merger formation in a market with turnover of market participants. We describe the dynamics of the model and identify the conditions under which market competition is sufficiently disrupted to prompt extended periods during which mergers are desirable. We also demonstrate how merger waves can be triggered by industry shocks and firm overconfidence. Copyright © 2012 John Wiley & Sons, Ltd.     

土地要素流动与二元经济结构转换：基于国情对刘易斯二元经济模型的修正

回顾文献,概括出了对二元经济理论进行创新的几个主要方向。在这些创新方向的启示下,考虑了由于现行土地制度使得二元结构被不断强化的特殊国情,借鉴和运用新古典经济学的分析技术,构建一个包含了土地要素流动的二元经济模型,并借此模型为我国的二元经济结构转换给出了简单的政策启示。     

Q/SHCG 35-2012《钻井液用合成聚合物降滤失剂技术要求》标准实施分析

介绍了标准制定的背景及技术关键点,并分析了标准实施后对产品质量的影响。标准提出并制定了"降解残余物"指标和"120℃/16 h老化后滤失量"指标,对现场在用产品存在的"合格而不好用"现象起到了较好的控制作用。标准实施后,中国石化钻井液用合成聚合物降滤失剂产品实际有效物平均含量从50%增加到70%,降解残余物从26%降低至16%。产品中无效固相成分减少了,对地层的污染减少了,达到了清洁生产、节能减排的目的。     

Product Market Competition,Managerial Incentives and Firm Valuation

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.     

公共消费的理论创新与政策选择

公共消费包括政府自身消费和社会性消费,以公共风险为逻辑基础,并兼具经济和社会双重属性,既有利于维护经济稳定平衡,是可持续发展的基础;又有利于促进社会公平正义,是国民素质和社会文明程度提高的保障。目前理论界对公共消费问题的探讨大多基于经济视角,基于经济与社会双重视角审视公共消费理论,应树立“消费者主权”意识,明确我国公共消费政策方向。
