Contracts, norms, and plural form governance

The organization of interfirm exchanges has become of critical importance in today’s business environment. Many scholars have criticized the inadequacies of legal contracts as mechanisms for governing exchange, especially in the face of uncertainty and dependence. Other scholars argue that it is not the contracts per se but the social contexts in which they are embedded that determine their effectiveness. This study investigates the performance implications of governance structures involving contractual agreements and relational social norms, individually and in combination (plural form) under varying conditions and forms of transactional uncertainty and relationship-specific adaptation. Hypotheses are developed and tested on a sample of 396 buyer-seller relationships. The results provide support for the plural form thesis—increasing the relational content of a governance structure containing contractual agreements enhances performance when transactional uncertainty is high, but not when it is low. Implications for theory and future research are discussed. Joseph P. Cannon (Ph.D., University of North Carolina) is an assistant professor of marketing at Colorado State University.

Optimal taxation and public provision for poverty reduction

The existing literature on optimal taxation typically assumes there exists a capacity to implement complex tax schemes, which is not necessarily the case for many developing countries. We examine the determinants of optimal redistributive policies in the context of a developing country that can only implement linear tax policies due to administrative reasons. Further, the reduction of poverty is typically the expressed goal of such countries, and this feature is also taken into account in our model. We derive the optimality conditions for linear income taxation, commodity taxation, and public provision of private and public goods for the poverty minimization case and compare the results to those derived under a general welfarist objective function. We also study the implications of informality on optimal redistributive policies for such countries. The exercise reveals non-trivial differences in optimal tax rules under the different assumptions.     

Trade Policy and Poverty In the United States: Theory and Evidence, 1947-1990*

This paper develops a two-sector general equilibrium model to examine the impact of technical progress, factor accumulation, labor growth, unemployment, trade policy, and the government's antipoverty programs on the rate of poverty. the results are then tested empirically using the data regarding the United States. We find that low unemployment, productivity growth, and government transfers have the expected effects of alleviating poverty; but trade liberalization has the unexpected effect of being associated with a major increase in poverty-a result contradicting traditional views.     

Determinants of corporate social responsibility disclosures: Evidence from India

Over the last few decades, a number of studies, mostly in the western countries, have investigated the nature and frequency of corporate social responsibility disclosures, their patterns and trends, and their general relationships with corporate size and profitability. This study seeks to extend the knowledge regarding the relationship between a number of financial and non-financial corporate characteristics and the level of social responsibility disclosures based on an extensive sample of top Indian companies. Corporate size and industry category are found to correlate with the corporate social disclosures of the companies and the corporate reputation as recognised through awards and social ratings has also been observed to be a significant factor that influences the social disclosures made by the Indian companies.     

Slotting allowances: a time series analysis of aggregate effects over three decades

Slotting fees and related discounts are important but controversial mechanisms for obtaining shelf space in marketing channels for consumer packaged goods. The theoretical field is divided between the efficient market and the market power schools of thought. Results from empirical studies and analytical models point in different directions. This paper analyzes trends in key macro economic variables to see if the patterns are more consistent with an underlying market efficiency model vs. a market power one. The data span 30+ years and focus on retailers in the marketing channel for food and kindred products. The variables studied include new product introductions, retail selling area, consumer price indices, profitability, cost of goods sold and selling expenditures. Efficient market explanations do not fare well in the analyses in comparison with market power explanations for practically all the variables studied. The paper conlcudes with recommendations for regulators and retail management.     

Competing with emerging market multinationals

A new breed of multinationals from emerging markets is appearing in many industries. Western firms are wrong to underestimate, as they often do, the competitive threat from these firms. The discussion herein highlights the non-traditional competitive advantages these firms use to win at home and abroad and shows how these firms use internationalization not only to exploit competitive advantage but to bolster it. The article concludes with suggestions for how Western managers should respond to the competitive threat from emerging market multinationals.     

基于卷筒纸胶印的印品在线缺陷检测系统

本文详细介绍了一种视觉系统,该系统可以实现对卷筒纸胶印过程中产生的印品缺陷进行检测和定位。具体来说,该系统能够对高速卷筒纸印刷进行实时监控,并且可在印刷过程中出现任何影响印品质量的故障（如结构缺陷、色彩偏差、漏字、墨点、墨杠等）时向操作人员发出警报。本文还介绍了机器视觉系统的硬件部分和用于彩色图像扫描及印品缺陷检测定位的图像处理算法。从本质上讲,该系统采用高速扫描算法检测图像的边缘和边界,利用线性和非线性的滤波器对动态大小、阈值和转换信息做进一步的分析。除了在实验室内进行实验以外,还建立了系统模型,系统模型可应用在卷筒纸印刷中,在真实条件下对模型的功能进行评价。将该系统安装在凹印机上进行实验,结果表明该机器视觉系统同样可以成功地对缺陷进行监控和检测。
