Activists’ Strategic Communication in an Authoritarian Setting: Integrating Social Movement Framing into Issues Management

Triangulating 18 in-depth interviews with activists and campaign participants, news coverage, and social media content related to the campaign “6,700 people for 6,700 trees,” this study integrates social movement framing theory and issues management framework to examine activists’ strategic communications in an authoritarian setting. Results indicate activists’ sophisticated use of framing strategies following different stages of the issue life cycle to legitimately form an issue and successfully manage the issue in order to achieve their goals. This study offers meaningful theoretical implications for examining strategic communication in social movement campaigns. It also discusses practical lessons for applying these strategies to foster social change in similar contexts.     

The environmental effect of trade liberalization: Evidence from China's manufacturing firms

While prior literature on trade liberalisation and the environment has mostly focused on the macroeconomic ramifications, this study explores at the firm level whether and how changes of trade barriers brought about by China's accession to the WTO may impact on its manufacturing firms’ environmental performance. Adopting a difference-in-differences (DID) methodology, we document the effects of tariff reductions on improving firm-level SO2 emission intensity, and the key corporate strategic decisions responsible for delivering the observed results, with robustness tests covering other major pollutants. In response to trade liberalisation, firms are found to increase labour resources for environmental protection and to improve their production processes to reduce emission intensity. This study contributes to the literature by investigating at the level of the operating firm how output and input tariff reductions may impact on environmental performance and uncovering for the first time the specific actions responsible for the results.

Project Ranking in Petroleum Exploration

Abstract

Project ranking based on project value is an essential management task for organizations that face resource bottlenecks. Project value focuses on the hard elements of projects that can be expressed in monetary terms. In the petroleum exploration business, however, there is also soft information, like effects on corporate liquidity, advantages of compliance with the strategic goals, or learning potential and organizational development, which may change the ranking hierarchy. The aim of this research is to provide a solution for incorporating industry-based selected soft data in the project ranking process. The process is illustrated with a case study. We took the structured system of criteria identified from the petroleum industry.     

连续创业者创业经验与再次创业成功关系研究——基于中国互联网行业面板数据的分析

通过研究中国互联网行业252位连续创业者创办的608家公司，对连续创业者先前创业经历与再次创业成功可能性间关系进行研究。从创业次数、退出状态、行业经验以及第一笔投资获取时间等维度进行分析，提出相应假设并运用最小二乘法进行验证。结果显示，创业次数及细分行业经验而不考虑先前创业业绩不能作为后续再次创业成功的可能性预估指标；创业次数越多与先前创业成功的创业者再次创业时倾向于等待更长时间才获取第一笔投资，而创业失败的创业者再次创业时第一笔投资获取时间更早；先前创业成功的创业者再次创业成功的可能性极高，而先前创业失败的创业者则容易再次失败；另外，无论创业者在相同还是不同细分行业进行再次创业，该关系都保持不变。最终，根据研究结果对投资者、政策制定者及创业者提出管理与政策建议。     

International R&D Spillovers: Trade,FDI, and Information Technology as Spillover Channels*

With the rapid pace of economic integration, the productivity of a country depends not only on domestic R&D, but also on foreign R&D through technology diffusion across countries. The advancement of information technology (IT) has made the international transmission of knowledge faster and more efficient, providing an important channel for international R&D spillovers. This paper investigates three channels of international R&D spillovers: trade, FDI, and information technology. Applying panel cointegration and dynamic OLS analysis to the data for 21 OECD countries plus Israel during the period from 1981 to 1998, we find that bilateral trade remains an important conduit for international R&D spillovers. Although bilateral FDI is found to be positively related to international R&D spillovers, their impact on productivity growth is relatively small. We also find that the development of information technology has played a more important role in international R&D spillovers and productivity growth in recent years.

What is the impact of problem loans on Japanese bank productivity growth?

This paper examines for the first time the impact of problem loans on Japanese productivity growth. We exploit a new data set of Japanese problem loans classified into two categories: bankrupt and restructured loans. We opt for a novel and flexible productivity growth decomposition that allows to measure the direct impact of these problem loans on productivity growth. The results reveal that Japanese bank productivity growth was severely constrained by bankrupt and restructured loans early in 2000s, whilst some persistence of the negative impact of problem loans on productivity growth is observed in the late 2000s. Thereafter, there is only some partial recovery in the productivity growth from 2012 to 2015. Further, we also perform cluster analysis to examine convergence or divergence across regions and over time. We observe limited convergence, though Regional Banks seem to form clusters in some regions.
