This paper examines how multinational corporations (MNCs) selectively assign supervisory responsibilities to units in countries with varying levels of institutional quality. Arbitraging across institutional contexts is an important function of MNCs, but it also creates coordination challenges. The choice of organization structure, such as the differential assignment of supervisory responsibilities, is an important tool for managing these coordination challenges. Using data on the business activities and supervision relationships within U.S. multinational manufacturers in 1996–2008, I find that frontline subsidiaries in countries with weaker institutions are more likely to be supervised by foreign rather than domestic supervisory units. Foreign supervision is even more likely when subsidiaries in weak-institution countries conduct activities that are more central to or interdependent with their parents' global operations. These findings confirm that MNCs use differential supervision to enhance global coordination. The paper highlights one of the most unique features of MNCs: a multinational hierarchy that resides within a firm's boundary but across national borders. It also connects MNCs' hierarchical structure with institutional imperfections that give rise to the emergence of the firm in the first place.

This paper studies the impact of task complexity and decomposability on the degree of organizational divisionalization and hierarchy within firms. Drawing upon the team theory and modularity literature, it argues that the degree of divisionalization is predicated not only on the extent of interdependence (complexity) among tasks but also on the extent to which those interdependent relationships are decomposable. As such, the feasibility and benefits of modularization in organizational design may be overstated when the underlying tasks are not decomposable. In addition, this paper argues that organizational hierarchy serves to mitigate the tension between complexity and decomposability by facilitating a higher degree of divisionalization. These arguments are tested using data on the business activities and organization structures of U.S. equipment manufacturers in 1993–2003. Results show that divisionalization increases with task complexity, suggesting that complex task systems encourage more division of managerial responsibilities. However, divisionalization decreases as task systems become less decomposable. Meanwhile, organizational hierarchy increases with task complexity, and it increases as task systems become less decomposable. These findings highlight the constraints firms face in designing modular organization structures and the role of hierarchy in coordinating complex task systems that are not fully decomposable.

Abstract
Social problem-solving skills (SPS) are essential to child development, especially for kunjing children without sufficient parental care (KCw/oSPC). This study aimed to design and implement a group-based pilot intervention programme to improve KCw/oSPC's SPS and assessed its effectiveness. This pilot intervention was a randomised controlled trial, fifty-seven KCw/oSPC at seventh grade (aged twelve to thirteen years) were recruited and randomly assigned into experimental (n = 24) and waiting (n = 33) groups. All participants in the experimental group received SPS training, whilst the waiting group did not receive any services at the research stage. Both pre- and post-test data about participants' SPS from both groups were analysed with Mann–Whitney–Wilcoxon and Wilcoxon signed-rank tests, respectively. Results indicated that KCw/oSPC's SPS in the experimental group improved significantly, with large effect size (Cohen's d = 1.15). This pilot study, although with limitations, contributed to informing future social work intervention studies and practice to promote KCw/oSPC's SPS in Mainland China and worldwide.

AbstractWe investigate the impact of the Dodd–Frank Act (DFA) on the credit risk behavior of complex bank holding companies (BHCs). Specifically, we assess the effectiveness of the DFA in reducing the credit riskiness of complex banks. Consistent with the moral hazard hypothesis, we find that complex BHCs affected by the DFA increase their credit risk. We argue that possible explanations are that BHCs decreased their lending portfolio quality, loan monitoring, and strength and independence of the risk management function after the DFA. The results are robust to endogeneity concerns, different sample selection criteria, various model and treatment specifications, and placebo tests.

AbstractGreen purchase behavior can significantly contribute to environmental protection, which should be further encouraged. In promoting green purchase behavior, individual green knowledge may play a vital role. This study aims to explore how and when green knowledge influences individual green purchase behavior. Based on trait activation theory, this study proposes that individuals with more green knowledge can better know the impact of their daily behaviors on the environment, including their consumption behaviors. Specifically, individuals with more green knowledge will have more environmental concerns and thus show higher preferences for green consumption. Further, by integrating the environment individuals live in, this study proposes that resource inadequacy will strengthen the effects of green knowledge. Survey data collected from 606 Chinese university students at three-time points supported our hypotheses. This study also discussed the theoretical and practical implications.

ABSTRACTSelf‐efficacy refers to an individual's judgement, belief and perception of their capability to accomplish specific tasks, which is crucial for children's mental well‐being. The primary objective of this scoping review was to systematically examine intervention studies aimed at enhancing children's self‐efficacy in Mainland China, intending to inform social work practices in child services. We conducted a comprehensive search of articles in Web of Science and CNKI to review empirical intervention studies published before March 2022 in either Chinese or English. The selection criteria included all empirical intervention studies focused on improving self‐efficacy in children in Mainland China. A total of 17 studies were identified and included in the review. Among these, six studies focused on general self‐efficacy, while the remaining 11 examined domain‐specific self‐efficacy. Seven studies provided compensatory interventions to children facing adversity, five studies implemented preventive services, and another five offered developmental services to children in regular circumstances. Fourteen programmes exclusively served children, while three studies involved parents. Notably, most of the included interventions were facilitated by research teams from universities, with only one led by a social work department. Education modalities and comprehensive interventions were commonly used and found to be effective. The current state of intervention studies underscores the need for programmes that utilize effective strategies and approaches to enhance children's self‐efficacy. Social workers are encouraged to play both direct and indirect roles in services aimed at improving children's self‐efficacy.
