Network industries often exhibit natural monopoly in certain markets. Here, natural monopoly is generally attributed to high sunk and fixed costs paired with low marginal costs. This chapter explains that digital platform markets are prone to concentration not only due to this combination of fixed and marginal costs but also due to self-reinforcing feedback loops that reinforce the dominance of the largest platform operators. Platform monopoly is persistent, entrenched, and the result of structural competition issues. However, even if digital markets exhibit heavily imperfect competition or natural monopoly, competitive pressures persist as there is competition at the ecosystem level. This sets apart digital platform monopoly from non-digital natural monopoly and means that regulating these markets should happen on the basis of different principles.

This chapter draws on past theories of ownership structure in the oil sector and applies them to the alluvial diamond sector in Zimbabwe. The alluvial diamond sector in Zimbabwe presents a natural experiment for understanding ownership structure in that the state and ruling party have been the same since 2006. Still, at least six different ownership regimes have been attempted. This chapter traces each of these and examines how the unpredictability of ownership in the diamond sector has often led to large-scale diamond smuggling and a regulatory framework reflective of political dynamics. The unpredictability of ownership has, in and of itself, caused difficulty in the Zimbabwean diamond sector and has reflected the unpredictability of state institutions. Thus, this chapter argues that past approaches that have been developed to examine the oil sector of states have some relevance for states that have a large amount of alluvial diamond wealth. However, the unique ability for a large amount of diamond wealth to be smuggled into a small space has made the significant increase in diamond wealth since 2006 a challenge for the formal economy and state capacity.

This chapter examines the development of the “mode of exchange” in Zimbabwe’s diamond sector. Before 2006, Zimbabwe’s small diamond production mostly went to Western Europe. During an extensive boom in diamond production from 2006 to 2010, many diamonds were smuggled out of the country amid foreign sanctions and a decline in the formal sector. Since 2010, the formal sector has bounced back, and many diamonds have been sold to the United Arab Emirates. Since 2016, Western Europe has once again become an export destination. However, in all periods, smuggling around the formal economy has persisted and had significant consequences for state capacity and institutions, which are examined in this chapter. This also traces the mode of exchange for other resources, particularly gold and lithium, which have been increasingly important. However, the drastic increase in diamond production that started in 2006 has uniquely impacted the Zimbabwean state. It provided an outlet to ZANU-PF during the economic collapse and increased political scrutiny, especially after the contested 2008 election, and contributed to the party being able to survive politically.

Chapter 1 introduces the main issues raised in Labour Law and its social and economic significance in regulating workplace relations. The chapter introduces the principal sources of labour law in the UK, which include statutes, the common law and European law and the difficulties in securing compliance by employers with those laws. It describes the system of employment tribunals and ordinary courts where disputes are resolved. Finally the chapter introduces some contemporary themes concerning precarious work, work/life balance and human rights at work.

This chapter deals with the issue of digital regulation, focusing on the complexities of addressing the growing challenges of cybercrime and online harm. While legal regulations offer clear standards and institutional frameworks for enforcement, they are often hindered by slow adaptation, jurisdictional conflicts, and inconsistent implementation. Surveillance and stricter controls, though promising as preventative measures, raise ethical concerns related to privacy, misuse of data, and the erosion of trust. The chapter suggests an approach stemming from fostering internal regulation through individual responsibility and intrinsic motivation as well as emphasising the role of digital ethics. By cultivating moral awareness, moral judgement, and critical thinking, individuals can be better equipped to navigate ethical dilemmas in the digital environment. Education is presented as an important way of developing this internal compass, with a focus on critical and reflective thinking and understanding the impact of actions. The chapter advocates for a complementary approach, where legal frameworks are enriched by ethical considerations and education.

This chapter investigates moderating factors such as trust-related mechanisms, norms, and institutions, and their ability to explain the relationship between intrinsic motivation and compliance, which is free of regulatory coercion.

Neoclassical economics is inherently biased against progressive policies and therefore should be avoided by progressives seeking to make the case for them. This is reflected in the history of regulation of payday loans and other fringe financial products. Conservatives used economic arguments to roll back regulation of these products in the second half of the twentieth century. Attempts to reregulate them have since been stymied despite progressives’ use of behavioral economic arguments to justify greater regulation. Progressives who eschew economic argument have had more success pursuing reform in other areas in the Biden Administration. The failure of behavioral economics to advance a progressive agenda in fringe finance suggests that inframarginalism, which also embraces the neoclassical analytic, will not help progressives. Another problem is that any neoclassical approach privileges elite expertise.

Antimicrobial resistance is a multidisciplinary issue that has been high in the global agenda since the 2015 WHO Global Action Plan (GAP) and the 2016 UNGA Declaration. The Quadripartite Coalition has set up a consolidated global governance structure to coordinate AMR responses, including a Global Leaders Group, an Independent Panel of Experts and a stakeholders’ platform. At the national level, countries have set up more or less formal mechanisms to coordinate AMR management, develop and implement National Action Plans.

This chapter will draw on these pilot experiences to identify options for broader One Health governance and regulation. The chapter will examine global and regional governance and regulation of AMR – focusing on the EU as a case study – to explore possible applications to other priority areas such as zoonotic diseases.

Rules for regulatory intervention aim to ensure that cumulative impacts remain or fall below thresholds of acceptable cumulative harm. A rule has two key dimensions: (1) its strategy – how it changes cumulative harm by reducing impacts, offsetting impacts, restoring, or facilitating coping with impacts; and (2) its approach – how it influences actions that cause impacts by using mandates (sticks), incentives (carrots) or information and persuasion (sermons) to influence adverse actions, or by using direct state action (state rescue). Each strategy and approach has strengths and weaknesses in addressing cumulative harms, and a cumulative environmental problem will likely need a carefully designed mix. In designing this mix, important challenges are ensuring connected decision-making so that actions are not considered in isolation; ensuring comprehensiveness, to avoid overlooking actions, including "de minimis" actions that could cause cumulatively significant impacts; managing costs related to intervention; and adapting interventions to accommodate changes to impacts and new information. Real-world examples illustrate legal mechanisms that include features designed to address these challenges.

Regulatory systems can be designed to surmount barriers and promote conditions for dealing with cumulative environmental problems using legal mechanisms that deliver four integrated functions: conceptualization, information, regulatory intervention, and coordination (the CIRCle Framework). Analyzing how a set of laws provides for these functions helps identify important weaknesses and gaps for improving laws. This chapter sets out a step-by-step guide to applying the CIRCle Framework and key design features for each function. It also highlights common themes that emerge from the book’s case studies, which center on environmental justice concerns related to groundwater in California’s Central Valley; cumulative impacts to the biodiversity of the Great Barrier Reef, Australia; and grasslands as biocultural landscapes in South Tyrol, Italy. Key themes point to the value of taking a wide view of relevant laws and available regulatory approaches and strategies and the importance of local factors, regardless of the governance scale of the problem. They show that integrating laws and functions can take time, but that evolution and improvement is possible.

Psychiatric disorders are highly comorbid and are not separated by sharp biological boundaries. Understanding the common mechanisms that explain symptom overlap in mental disorders is therefore clearly needed. Here, we briefly review impaired emotional processing and emotional dysregulation in affective disorders, with a special focus on unipolar depression. Affective disorders are characterized by abnormal emotion intensity, changes in the temporal dynamics of emotion and difficulties to influence the trajectory of emotions. Disruptions in emotion processing and emotional regulation are underlined at the neural level by abnormal interactions between cortical and limbic structures in terms of increased variance in functional connectivity. Emotional processes are also tightly linked to cognitive processes, which constitute main targets for therapeutic interventions in affective disorders.

Decades of research demonstrate cultural variation in different aspects of emotion, including the focus of emotion, expressive values and norms, and experiential ideals and values. These studies have focused primarily on Western and East Asian cultural comparisons, although recent work has included Latinx samples. In this chapter, we discuss why studying culture is important for studies of emotion and what neuroscientific methods can contribute to our understanding of culture and emotion. We then describe research that uses neuroscientific methods to explore both cultural differences and similarities in emotion. Finally, we discuss current challenges and outstanding questions for future research.

This chapter explores the interplay between emotions and memory, highlighting the interrelations between regulatory and memory processes. In the first section we describe how, through indirect and direct influences, emotions impact every phase of the episodic memory cycle: encoding, consolidation, and retrieval. Whereas many of these influences are attributed to the amygdala and hippocampus, recent work has emphasized the role of a broad network of regions, extending well beyond these medial temporal lobe regions. In the second section, we focus on the role of the dorsomedial prefrontal cortex in adjusting the content, emotionality, and narrative context at each phase of the episodic memory cycle. In the third section, we discuss the reciprocal interactions between emotions and memory: Our memories serve as triggers for emotions and can be used as an emotion regulation device, while our emotions and emotion regulation goals can likewise influence our memories. The final section highlights broad directions for future research.
