股权激励、契约异质性与实体企业金融化

从股权激励视角切入,利用2008—2019年沪深A股上市公司的经验数据,探究股权激励对企业金融化的影响。研究发现：从整体上看,股权激励会抑制企业金融化。基于微观契约层面,股权激励强度越大,股权激励对企业金融化的抑制程度越大;相较于限制性股票,股票期权对企业金融化的抑制程度更大;只有激励期限较长的股权激励才会抑制企业金融化。作用机制检验表明,股权激励会降低股东与管理层之间的代理成本、缓解融资约束进而抑制企业金融化。研究结论有助于充实和深化股权激励与企业金融化关系研究,也为从公司内部治理层面防范和化解实体经济风险提供证据支持。     

Pursuing your leader development: Lessons from 101 executives

To lead effectively in a VUCA (i.e., volatile, uncertain, complex, and ambiguous) environment, leaders must quickly and continuously acquire new skills. However, formal development opportunities aren’t nearly enough to support the ongoing skill development leaders need to manage the level of complexity and change they are facing. Instead, leaders must take ownership of their own development. In this paper, we describe a straightforward, four-step process that leaders can implement to pursue their individualized development through leader development planning. Specifically, we walk leaders through the evidence-based steps of creating their unique leader development plan (LDP), including (1) identifying their leadership strengths and weaknesses, (2) setting effective leader development goals, (3) designing SMART strategies, and (4) reflecting, refining, and realigning their plan. Throughout the article, we detail positive examples as well as common pitfalls that we observed from our work supporting 101 mid- to senior-level leaders in designing their LDPs. Our purpose in doing so is to provide tools and examples to enable leaders at all levels to drive their development at their own pace.     

The mediating effect of psychological empowerment on the relationship between participative goal setting and team outcomes – a study in China

In the late twentieth century, it is popular to research the effect of participative goal setting. The general conclusion is that the relationship between participation and performance is inconsistent and unclear at individual level. With team becoming a more dominant mode in organizing, motivating, and managing, it is worthwhile to investigate the effect of participation in team goal setting. This study aims to test the mediating effect of psychological empowerment (PE) on the relationship between participative team goal setting and team identity and team performance. Executive MBA students (371) in 75 groups from China Europe International Business School in China participated in the study. The data from Business Strategy Game and questionnaire found positive relationship between participative team goal setting and team identification, and team performance is partially mediated by PE. Implications for the goal-setting theory and practice are discussed, and future research directions offered.     

The Political Economy of Policy Vacuums: The European Commission on Demographic Change

ABSTRACT

Supranational organisations can only confront politico-economic issues that are recognised as important. Typically, issues gain recognition either when they provide an external shock to the system, shaking political actors into action, or when they are framed as important in policy networks concerned with developing the appropriate scientific approach. Ideally political and scientific actors align in creating pressures to recognise the issue as salient and to mobilise organisational responses. Issues differ in their capacity to be driven by both political and scientific pressures, creating crisis management, technocratic, and reform agenda outcomes. Here we explore a further variation, where pressures around an issue are insufficient, creating a policy vacuum. We examine one such policy vacuum in Europe: demographic change. This issue belongs to no particular Directorate-General in the European Commission, but is subject to policy frames from DG EMPL and DG ECFIN. Without sufficient political and scientific pressures, no particular policy position is occupied and advocated despite recognition of the issue’s importance. We discuss the role of policy vacuums and the need for their identification in political economy research.
