上市公司股东不可撤销表决权委托研究——问题、挑战与监管

表决权是上市公司股东参与管理决策的重要方式。证券监管实践表明,不可撤销表决权委托既有规避股份限售和减持规则的动机,也有出于增强控制权转让交易中博弈弹性的考虑。表决权委托并非一项简单的债权债务法律关系,其合规性及对证券市场的影响需引起足够的重视。为规范上市公司股东不可撤销的表决权委托,本文建议:在信息披露监管方面,重点关注表决权委托对权益变动、控制权稳定性、投资者保护的影响;在制度规范方面,发布表决权委托示范协议指引等规则,明确表决权委托的关键要素和监管要求。

Cost Analysis of Calcium in Store Brand versus National Brand Grocery Products

Objective: This study was to determine if calcium fortification yields a higher price per serving in grocery store products. Researchers compared store brand to national brand grocery products in relation to cost in order to examine if calcium values were similar between store brand and national brand products. Methods: A total of 112 store brand and 211 national brand grocery products were collected from three low (national chain store), middle and high priced (Virginia and North Carolina regional store) grocery venues. Products were compared using price and calcium percentage per serving. ANOVA was used to determine between store brand and national brand for price per serving and calcium content, and between grocery venues. Results: National brand fortified products had a significantly lower mean price per serving when compared to national brand non-fortified products (p = 0.0002). There was no statistical difference between store brand fortified and non-fortified products (p = 0.9256). Low priced store brand products had the lowest mean price per serving ($0.34 ±0.24). Conclusions: This study found store brand products have similar calcium content as national brand products. Product cost was lower at low priced store compared to middle and high priced stores.     

Estimating emissions based on the integration of microscopic traffic simulation and vehicle dynamics model

This study proposes an integrated simulation approach, which consists of a microscopic traffic simulation model, a vehicle dynamics model, and an emission estimation model, in order to estimate emissions based on more reliable vehicle performance measures. The vehicle performance measures such as engine power and engine speed significantly relate to the amount of emissions, and road curvatures and inclinations are the core inputs affecting these vehicle performance measures. Therefore, providing reliable vehicle performance measures reflecting the road geometric attributes is critical for a reliable emission estimation. This study proposes to use the microscopic traffic simulation model for generating vehicle trajectories, which is advantageous in modeling various traffic situations, and the vehicle dynamics model for producing the vehicle performance measures based on the vehicle trajectories. Finally, the outputs from the vehicle dynamics model are fed into the emission estimation model to compute emission measures. This study conducted a case-study using two road sections, one is a hypothesized road section, including various curvatures and inclinations with regular variations, and the other is a Kesselberg road section, which is an actual geometry in Bayern, Germany. The emission measures are estimated in these case-study road sections using both an existing simulation approach and the proposed integrated simulation approach. The difference between these two emission estimation approaches is discussed in terms of the emission measures, including fuel consumption, nitrogen oxides, and particulate matters.     

The State as Both Regulator and Player: The Politics of Transfer of Development Rights in China

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.     

Negative interest rate policy and the yield curve

We evaluate the implications of the ECB's negative interest rate policy (NIRP) on the yield curve. To capture various shapes of the short end of the yield curve induced by the NIRP, we introduce two policy indicators, which summarize the immediate and longer horizon future monetary policy stances. We find that the four NIRP events lowered the short-term interest rate by the same amount. The impact is dampened at longer maturities for the first two event dates, due to lack of forward guidance. By contrast, for the last two dates, forward guidance drives the largest effects in two years.     

Twenty‐eight years of business strategy and the environment research: A bibliometric analysis

The competitive academic climate of all the academic fields, including business strategy, puts great stress to publish. To effectively maneuver the field of business strategy and the environment, all the stakeholders, such as academicians and practitioners, must understand the current position of the theory and practice. A systematic bibliometric analysis of a top tier journal can serve this issue by providing a holistic view of the publications' trends and trajectories. This study analyzes the trend of publication in the Business Strategy and the Environment (BSE) Journal since its inception in 1992 to 2019. The study uses two procedures to analyze the bibliometric data collected from the Scopus database. First, we use different aspects such as citation and publication structure to estimate the evolution of the BSE; second, we use VOS viewer software to visualize the mapping of BSE based on co‐citation, bibliographic coupling (BC), and co‐occurrence (CC). The results show a gradual increase in the citation and publication structure of the BSE. The increase in publications and citations indicates BSE's growing stature as a key academic outlet advancing knowledge in business strategy and environmental sustainability research. This study contributes to the literature by identifying the most influential aspects of the journal, which would help researchers to understand the trends and focus of the BSE.
