农户土地流转有助于农户群体“提低扩中”吗?

提高中低收入农户群体的收入水平是缩小居民收入差距、实现共同富裕的关键任务。利用CFPS 2018数据,使用基于RIF的ITE模型等计量方法进行分析研究发现：(1)土地流转的增收效应具有非对称性,转出土地的中低收入农户能显著增收,但转入土地的中低收入农户增收不明显;(2)东部和西部地区转出土地的中低收入农户收入增长显著;(3)土地流转(尤其是转出)有助于缩小农户间收入差距、优化农户群体的收入分配结构。实证结果稳健地说明农户土地流转对实现农户群体“提低扩中”目标具有积极意义,在此基础上提出在西部和东中部欠发达农村地区,鼓励和支持中低收入农户流转土地,以增加其兼业和非农收入等政策建议。     

长三角一体化发展的边界效应研究——基于城际消费流视角

随着社会技术的进步与市场经济的深化，消费流在反映区域间经济活动的往来程度时显现出了优势。文章借助中国银联2018年城际消费流数据，基于调整后的Head-Mayer边界效应模型，对长三角城市群的市场一体化程度进行测算和评估。实证结果表明：长三角地区的统一市场尚未完全形成，城市边界和省际边界均对异地消费具有抑制作用；省际边界效应表现出异质性，其中上海与其他三省之间的边界对消费流的影响相对较弱，而浙江、江苏、安徽三省彼此之间的市场分割更为明显；长三角各城市的边界效应程度不尽相同，上海的城市边界效应强度为1.05，江苏省各城市的边界效应强度处于3.06~5.51之间，浙江省各城市的边界效应强度介于3.13~6.24之间，而安徽省各城市的边界效应程度最为强烈，在3.85~6.58之间分布。基于长三角区域经济一体化的发展现状，提出以下几点建议：首先，要肯定区域经济协调组织在推动区域经济发展过程中发挥的重要作用。其次，继续深化取消影响区域经济发展的人为阻碍的改革，进一步降低经济合作的障碍和成本。最后，需要积极借鉴国际区域合作经验来推动长三角地区发展。     

Kinship care or upbringing by relatives? The need for ‘new’ understandings in research

This article addresses knowledge production on formal kinship foster care. In spite of growing interest in this phenomenon, little attention has been paid to how kinship care should be understood in research – as a service under child protective services or as upbringing by relatives. Each of these understandings leads to different research questions and creates guidelines for what falls into or outwith the focus of research. In kinship care research, this phenomenon has primarily been studied as a service. Research that seeks to evaluate the effect of kinship care compared to non-kinship care is used as a case to discuss the implications for the type of knowledge that researchers produce. While we acknowledge the importance of this research, we demonstrate the many challenges it involves and why this should not be the primary focus in kinship care research. On the background of these limitations, we argue in favour of approaching kinship care as upbringing by relatives – as ways in which family life can be organised and structured. This can lead to relevant knowledge that will enable us to obtain a better understanding of what kinship care is and involves.     

Cross-border credit networks,banking risk contagion and suppression effects

From the perspective of risk contagion, it is difficult to balance the benefits and costs of banking globalization. We use data on cross-border syndicated loans intended to build heterogeneous credit networks among banking sectors in various countries to explore the introduction of banking risks into the network. Via social network analysis (SNA), we find that the global credit network has phased characteristics, and it is a source of exposure to global banking risks. However, the more important network position, that is, the greater centrality, identified shows that the banking industry is more stable. To explain these findings, we present and estimate the banking risk contagion model and the suppression effect model of contagion. Evidence suggests that the international credit network is the channel of risk contagion, and the long-term loan network and nonfinancial borrower network have a stronger contagion effect. Exogenous banking supervision and network endogenous closeness centrality can inhibit risk contagion. From a policy perspective, these findings indicate the need to supervise high-risk cross-border loans and maintain independence in the international credit network.Data Availability StatementThe data that support the findings of this study are available from the corresponding author, [Heng Zhao, email: zhao0501@mail.dlut.edu.cn], upon reasonable request.     

Short- and long-term effects of divorce and separation on housing tenure in England and Wales

This paper investigates the effects of marital and non-marital separation on individuals’ housing tenure in England and Wales. We apply competing risks event history models to data from the British Household Panel Survey and the UK Household Longitudinal Study to analyse the risk of a residential move to different tenure types, for single, married, cohabiting, and separated men and women. Separated individuals are more likely to move and experience a tenure change than those who are single or in a relationship. Among separated people, private renting is the most common outcome of a move; however, women are also likely to move to social renting, whereas men tend to move to homeownership. This pattern persists when we account for time since separation and order of move, indicating a potential long-term effect of separation on housing tenure. This long-term effect is especially pertinent to separated women who cannot afford homeownership.

How the Pygmalion Effect operates in intra-family succession: Shared expectations in family SMEs

The Pygmalion Effect is a case of the self-fulfilling prophecy, whereby the expectations of leaders influence the performance of followers (Avolio, Walumbwa, & Weber, 2009; Rosenthal, 1993). Intra-family succession processes, which are hardly ever formalised in small- and medium-sized family enterprises, provide a natural context to explore the perceptions that predecessors have about their successors and where the Pygmalion Effect is expected to occur. However, little is known about how a predecessor’s expectations can affect intra-family firm succession processes. Based on qualitative interviews with key family and non-family members, expectations were analysed in four in-depth case studies of intra-family SME succession processes. The findings show that the Pygmalion Effect operates over time and embraces incumbent, successor, and key stakeholders’ expectations, which support the new leader when facing succession-related challenges.     

Does exposure to a traumatic event make organizations resilient?

Why do some organizations bounce-back from traumatic events more quickly than others? While the research on organizations offers extensive insights on recovery from economic or technological shocks, there is limited understanding of how organizations recover from life-threatening events such as terrorist attacks. In this study, we build on the research on resilience and argue that organizational recovery from a traumatic event is informed by the perception of threat. Higher perception of threat increases inter-organizational collaboration and the care associated with the deployment of slack as well as to learning. We tested our arguments with a sample of US and non-US firms before and after the 9/11 terrorist attacks and found that, due to spatial proximity, US firms’ higher perception of threat led to a larger increase in the frequency of inter-organizational alliances than that of non-US firms. This preference was more frequently directed towards local partners and demonstrated a distinct emphasis on slack and learning. Contrary to conventional wisdom, our findings suggest that organizational resilience in the face of a traumatic event benefits not from immunity but from spatial proximity to the threat. Proximity increases the perception of threat, and with it, the impetus for adaptation.
