宏观经济政策是否有效——基于理性预期模型的分析

自《通论》发表以来,关于宏观经济政策是否有效的争论一直贯穿于整个宏观经济学界。因此,从理性预期模型出发,对于宏观经济政策是否有效进行了再分析,通过博弈论思想的引入探究了宏观经济政策能否达到理想效果。在对扩张性宏观经济政策实际效果进行分析时指出了为何会出现“滞涨”,为何近年中国经济能够实现高增长低通胀的问题。     

Remanufacturing for the Circular Economy: An Examination of Consumer Switching Behavior

For the circular economy to be tenable, consumers need to not only return products after use, but also purchase products that are remanufactured. However, research finds that consumers have a poor opinion of remanufactured products and are typically not prepared to adopt them. Thus, development of the circular economy is dependent upon deeper understanding of consumers’ attitudes and behaviors. Research typically considers either micro‐level or macro‐level factors when assessing consumer perceptions of remanufactured products. The current research incorporates macro‐level factors of price, government incentives and environmental benefits with the moderating influence of micro‐level consumer attitudes to examine consumers’ intention to switch from purchasing new products to remanufactured products. The findings suggest that a consumer's attitude toward remanufactured products is an important moderating factor predicting consumer switching behavior to remanufactured products.

英语读写素质研究中的二元理论分析

英语读写素质是习得读写能力并形成读写体验的过程。读写素质主要由分析能力、结合社会文化能力、话语分类能力、读写实践能力、记忆能力、情感反应、思辨能力和隐喻理解能力等因素构成。本文首先应用二元理论中的集对分析理论分析了句子、语法和词语,英语句子具有同异性,英语语法中时态的相关性均有特定的语法表征手段,英语词语是一种约定俗成的语言单位常常附衍了一串同义词、近义词和反义词。如果用联系数来描述词语的相关度,它同时也反映出了词语的思想丰度。本文还运用博弈理论和悖论分析文章的含义及价值,最后应用模糊二元对比排序法对英语读写素质各因素进行分析,通过分析确定了各因素的重要度,将其应用于读写素质研究中具有积极作用并具一定的发展潜力。     

Is earnings management opportunistic or beneficial? An agency theory perspective

Earnings management has been cast into negative light due to the recent corporate scandals and, therefore, is viewed as detrimental to the firm. Enron and Worldcom represent two of the most egregious cases of opportunistic earnings management that led to the largest bankruptcies in U.S. history. However, some argue that earnings management may be beneficial because it improves the information value of earnings by conveying private information to the stockholders and the public. We offer agency theory as a tool to distinguish between the opportunistic and beneficial uses of earnings management. The empirical evidence suggests that firms where earnings management occurs to a larger (less) extent suffer less (more) agency costs. Moreover, a positive relation is documented between firm value and the extent of earnings management. Taken together, the results reveal that earnings management is, on average, not detrimental.

The Exchange Rate and Inflation in Argentina: A Classical Critique of Orthodox and Heterodox Policy Prescriptions

In this paper we present an alternative framework to neoclassical theory of international trade and exchange rate determination. Our model, inspired in the classical tradition, provides support for the assertion that an exchange rate policy aiming to improve national competitiveness and to bring about a sustained trade surplus is a viable option. In fact, the success of this strategy does not depend on the effectiveness of monetary sterilization —as many argentinean heterodox authors claim— but on the ability to overcome the boundaries imposed by the evolution of the domestic wage rate and the potential emergence of competitive devaluations. In the particular case of Argentina, the introduction of export taxes on land-intensive commodities, in which the economy has absolute advantages, brings an additional policy tool that can make both the exchange rate target and the workers claims consistent.     

Unleashing the Power of Networks: Shareholder Activism,Sustainable Development and Corporate Environmental Policy

In recent years, a new trend has emerged in which shareholder activists have formed networks to empower shareholders and magnify shareholder voices. This study explores the structural patterns and effectiveness of shareholder activism networks and shows how those networks affect corporate sustainability policies. We draw upon stakeholder influence theory, stakeholder network management theory and recent studies on activism networks to examine a shareholder activism network formed around environmental issues. The study found that (1) the structure of shareholder activist networks is largely driven by organizational attributes such as organization type, organizations’ human resources, media visibility and history; and (2) activist organizations with high centralities and eigenvector centralities enjoy more efficient results. This study contributes to our understanding of the business responses to shareholder demands on improving environmental performance and paves the way for future research on sustainable development through partnerships with shareholder networks.

Labour unions and leverage: evidence from firm-level union data

ABSTRACT

Using firm-level labour union data from Japan, this paper investigates the effect of labour unions on firm leverage. We find that as union coverage increases, both the level of and extent of change in leverage decreases. These relations remain robust when a firm falls into deficit. We also find that firms with higher union coverage have a higher interest coverage ratio. In addition, we find that firms with higher union coverage are less likely to choose issuing debt compared to issuing equity when they face financial distress. Our results imply that significant employee influence enhanced by labour unions increases fixed costs, crowds out the firm’s debt capacity and consequently reduces the firm’s leverage.
