A theory of exploitative child labor

We develop a model in which some child labor is exploitative.Since exploited child laborers are paid less than the valueof the marginal product of labor, there is scope for policyintervention to be Pareto improving. We illustrate this by showingthat a system of inspection and fines targeted on exploitativechild labor increases the aggregate output produced by children.We also establish that such intervention secures the releaseof children from exploitative working conditions, to their benefit.The distributional implications of the intervention among employersand among children who had not been exploited depends on whethercapital is mobile internationally, and can depend on whetherthe elimination of exploitative child labor is partial or complete.     

中国制造业贸易隐含碳与低碳贸易竞争力分析

采用增加值核算法测算中国整体制造业及高碳制造业出口隐含碳生产率,分析其低碳贸易竞争力;基于STIRPAT模型从技术和结构两方面研判低碳贸易竞争力的影响因素,预测基准、低碳技术、出口结构优化、能源结构绿色、低碳综合等5种情景下2021—2030年的低碳贸易竞争力。结果表明:中国出口增加将加剧国内减排压力,出口中90%以上的隐含碳都留在国内;能源利用效率是整体制造业低碳贸易竞争力的首要影响因素,能源消费结构对高碳行业影响较大;按发展趋势,2030年制整体造业出口隐含碳生产率略低于欧盟1995年的发展水平,低碳贸易竞争力较低;按“十四五”政策目标发展,2030年整体制造业隐含碳生产率将达到欧盟2003年的水平,高碳行业中的非金属制品业能超过欧盟2018年的水平。     

Can social awareness be increased through business school curricula?

The study was prompted by (a) Frederick and Vogel's debate concerning future research in “business and society”, (b) such recently reported managerial excesses as golden parachutes, “greenmail”, and fraud, (c) the increasing emphasis on coursework in the area. It appears that there is a need to assess how students, our future business leaders, perceive social issues and if a “business and society” course can help them define and understand the importance of these issues. Three questions provided the focal point: (1) Which issues do students perceive as most important before and after completing the course? (2) How much importance do students place on issues? (3) Does completing a “business and society” course make a significant difference in how students perceive the importance of the issues presented? Students appeared to have already clearly defined priorities before entering the course as there was very little post-course reordering of priorities. However, they did display an increased perception of the importance of social issues. The study also indicated that a “business and society” course can contribute to an increased student awareness of the importance of social issues. Therefore, it was concluded that a “business and society” course can help students define and evaluate the importance of social issues.     

Medication adherence and discontinuation of long-acting injectable versus oral antipsychotics in patients with schizophrenia or bipolar disorder

Aims: To examine medication adherence and discontinuation in two separate groups of patients with schizophrenia or bipolar disorder (BD), who began receiving a long-acting injectable antipsychotic (LAI) versus those who changed to a different oral antipsychotic monotherapy.

Materials and methods: The Truven Health Analytics MarketScan Multi-State Medicaid claims database was used to identify patients with schizophrenia; Truven Health Analytics MarketScan Commercial and Medicaid claims databases were used to identify patients with BD. The analyses included adult patients (≥18 years) who either began receiving an LAI (no prior LAI therapy) or changed to a different oral antipsychotic (monotherapy). The first day of initiating an LAI or changing to a new oral antipsychotic was the index date. Linear and Cox regression models were conducted to estimate medication adherence (proportion of days covered [PDC]) and time to medication discontinuation (continuous medication gap ≥60 days), respectively. Models adjusted for patient demographic and clinical characteristics, baseline medication use, and baseline ED or hospitalizations.

Results: Patients with schizophrenia (N?=?5638) who began receiving LAIs had better medication adherence (5% higher adjusted mean adherence) during the 1 year post-index period and were 20% less likely to discontinue their medication during the entire follow-up period than patients who changed to a different oral antipsychotic monotherapy, adjusting for differences between LAI users and oral users. Similarly, patients with BD (N?=?11,344) who began receiving LAIs also had 5% better medication adherence and were 19% less likely to discontinue their medication than those using oral antipsychotics.

Limitations: Clinical differences unmeasurable in this database may have been responsible for the choice of LAI versus oral antipsychotics, and these differences may be responsible for some of the adherence advantages observed.

Conclusions: This real-world study suggests that patients with schizophrenia or BD who began receiving LAIs had better medication adherence and lower discontinuation risk than those who changed to a different oral antipsychotic monotherapy.     

Quality choice: Does it matter which workers own and manage the cooperative firm?

The information age and the spread of information technology has implications for organizational structure. Accordingly, the age-old issues of product and service quality are put into a new perspective. It is this new perspective that compels analysis and contrast of the joint quality and output choices of a labor-managed (LM) firm with those of its entrepreneurial (PM) twin. It is shown that the LM firm's behavior regarding quality and quantity depends on which workers own and manage the firm and on the way that marginal profit with respect to output is influenced by quality. Similarly, the effects of increases in either fixed costs or demand depend on who owns and manages the LM firm and on the relationship between marginal profit and quality. Thus, whether a cooperative will outperform or underperform its PM counterpart depends on the particulars of the situation. An earlier draft of this paper was presented at seminars at Academia Sinica in Taipei and the Chinese University of Hong Kong. The authors are grateful to the participants in those seminars and most especially to Professors C. C. Mai, Eden Yu, and Dr. Li Tianyou, as well as to an anonymous referee for their comments and helpful suggestions. The authors are responsible for the final version.     

Technology Education in Ontario: Evolution, Achievements, Critiques and Challenges. Part 1: The Context

This article, in seven sections, describes the evolution of technological education in the Canadian province of Ontario. The first section clarifies the meanings of the terms technology and technological education. The second outlines significant events in the history of technical education in the province. The third examines some of the societal factors that have created a climate for change during the past two decades, while the fourth describes the broader context of recent curriculum developments. The fifth reports on the introduction in 1995 of The Common Curriculum and the publication of Broad-based Technological Education. The sixth provides a few case studies illustrating the variety of ways in which technology education is currently implemented. The seventh section offers an evaluation and critique of some aspects of provincial curriculum policy and practice. The article is published in two parts. Part 1, in this issue, contains the first five sections, which describe the current curriculum offerings and their evolution. Part 2, containing the remaining two sections and all references, will be published in the next issue. This revised version was published online in July 2006 with corrections to the Cover Date.     

The experience of forming business relationships in tourism

This study examines the formation of business relationships among tourism organisations. A phenomenographic study conducted with 25 managers drawn from regional tourism organisations in Queensland, Australia revealed three qualitatively different but interrelated ways of experiencing relationships: as competition, co‐operation and collaboration. Differences among experiences were accounted for by the way managers defined the meanings of several dimensions common to each experience. The results suggest managers' experiences can be developmentally ordered on a continuum of relationships that demonstrate progressively more complex and inclusive approaches to forming relationships.
