Efficiency properties of strategies market games: An axiomatic approach

The paper investigates the conditions under which an abstractly given market game will have the property that if there is a continuum of traders then every noncooperative equilibrium is Walrasian. In orther words, we look for a general axiomatization of Cournot's well-known result. Besides some convexity, continuity, and nondegeneracy hypotheses, the crucial axioms are: anonymity (i.e., the names of traders are irrelevant to the market) and aggregation (i.e., the net trade received by a trader depends only on his own action and the mean action of all traders). It is also shown that the same axioms do not guarantee efficiency if there is only a finite number of traders. Some examples are discussed and a notion of strict noncooperative equilibrium for anonymous games is introduced.     

Shark repellents and the role of institutional investors in corporate governance

This paper examines the role of institutional shareholders in monitoring managers when they propose antitakeover charter amendments (shark repellents). These proposals provide a rare opportunity to examine this issue since they can be adopted only by shareholder approval. We document a positive relationship between the ownership of institutional shareholders and the stock market reaction to the announcement of antitakeover amendments. This finding is consistent with the Demsetz (1983) and Shleifer and Vishny (1986) proposition that large blockholders reduce the free-rider problem associated with monitoring managers.     

Incentives, Risk, and Agency Costs in the Choice of Contractual Arrangements in Agriculture

The author develops a theory of the choice of contractual arrangements in agriculture by analyzing the incentives, risk-premia, and agency (supervision and shirking) costs under different contracts using the principal–agent framework. The theory is able to explain many tenancy-related issues, such as why sharecropping can be the optimal contract even in the presence of considerable shirking by the tiller, the predominance of sharecropping and of the 50*T*:*T*50 output share, the coexistence of sharecropping with other contracts, and the tenancy ladder.

Corporate Public Issue Advertising

This article presents the results of a study of the attitudes of chief executives regarding issue advertising. The study used a set of four issue advertisements representing varying degrees of self-interest. The results indicate marked differences between business leaders in their perceptions of both the usefulness and favourability of different issue advertising messages.     

基于邻近值的HEVC帧内预测优化

高性能视频编码(High Efficiency Video Coding,HEVC)标准中的帧内编码模式利用当前帧中像素点之间的空间相关性作出有效预测。为了解决待编码像素远离参考像素时预测不准确的问题,提出了一种基于邻近值的HEVC帧内预测优化算法。该算法的主要思想是,对于当前像素,先根据传统HEVC帧内编码方法得到其预测值,再使用该像素点左边、左上、上边位置的修正值以及该像素本身的预测值对该预测值进行修正。因为将当前像素与周围像素的相关性进行了有效的数学建模,所以HEVC帧内编码性能得到了提升。实验结果显示,所提算法与HEVC标准相比,最高节省了2.7%的码率,平均节省的码率为1.3%。     

Accounting Scandals in IPO Firms: Do Underwriters and VCs Help?

We examine whether underwriter reputation, venture capitalist (VC) backing, and VC reputation are related to the probability that a newly public firm has serious accounting problems. Using a novel data set, we find that the probability of restatement by an initial public offering (IPO) firm is positively related to underwriter reputation and negatively related to VC backing, VC reputation, and VC maturity. Our results do not appear to be driven by the endogeneity of underwriter reputation or VC backing. Our findings suggest that while VCs positively influence the financial reporting quality of IPO firms, underwriters’ concerns about revenue generation outweigh their concerns about reputation.     

Games within borders: are geographically differentiated taxes optimal?

The discontinuous tax treatment of sales at borders creates incentives for individuals to cross-border shop. This paper addresses whether it is optimal for a state composed of multiple regions to levy differentiated commodity tax rates across the regions. In a model where states maximize social welfare, a state’s optimal commodity tax system is almost always geographically differentiated. The optimal pattern of geographic differentiation critically depends on fundamental parameters as well as whether the state has a preference for high or low taxes. Under the assumption that utility is linear in consumption and that the elasticity of cross-border shopping is less than unity in absolute value, high-tax states will find it optimal to set a tax rate that is lower in the border region than in the periphery region and low-tax states will find it optimal to set a tax rate that is higher in the border region than in the periphery region. Optimizing high-tax states will set a higher tax rate in the border region if the social welfare measure is sufficiently redistributive. With welfare maximization, it is possible for taxes to be higher in the region near the state border—an outcome that cannot arise when the government cares only about total tax revenue.     

Assessing people-driven factors for circular economy practices in small and medium-sized enterprise supply chains: Business strategies and environmental perspectives

Globalisation and technological advancements have increased the pressure on small businesses to increase their productivity and to gain competitive advantages. That pressure has been placed on the resources available, resulting in increased environmental degradation as a result of the traditional linear model of make-use-dispose. Circular economy (CE) practices offer the opportunity for sustainable production based on the reuse-remanufacture and recycling of resources for small and medium-sized enterprises (SMEs) to increase their sustainability, resulting in enhanced performance levels in terms of business strategies and environmental perspectives. But in academic literature, the role of people-driven factors (PDFs) in the adoption of CE practices in the supply chains (SCs) of SMEs is limited. Therefore, to fill this literature gap, this research looks at analysing PDFs for the implementation of CE in the SMEs in developing countries in two phases. PDFs are identified from an extensive literature review; a DEMATEL technique is then employed to understand the significant influence of each factor in the adoption of CE practices in SCs by dividing them into cause–effect groups. The findings show that PDFs such as training and knowledge sharing, employee participation, leadership and management plus strategic alignment are considered to be the most important significant factors in the adoption. The findings of this study will help industrial managers to understand the significance of the role of PDFs for enhancing business strategies; these findings can reduce the negative environmental impact in the adoption of CE practices in the SCs of SMEs.
