Using Alabama as a case study of the beauty industry, this paper will demonstrate how licensing laws and regulations affected barbers and beauticians as they struggled to gain more clientele than their competitors. In the early twentieth century, white men dominated the market for cutting hair. Though the process started mid-century, by 1980, that relationship was inverted as women found themselves far outnumbering men. This research helps explain the gendered inversion of labor market trends while providing more general insights into the role of licensing laws in labor markets. Importantly, this work explores how race shaped labor market regulations, which affected and continue to affect labor markets and individual businesses in important ways.

Genome editing, prominently led by the revolutionary CRISPR-Cas9 technology, is a powerful tool with significant applications in diverse fields, particularly in medicine and agriculture. It empowers scientists with the ability to effect precise genetic modifications, thereby potentially paving the way for advanced treatments for genetic disorders such as Huntington’s disease, hemophilia, and cystic fibrosis. Yet, the significant capabilities of this technology also brings to the fore a myriad of intricate bioethical, legal, and regulatory dilemmas. In light of these complexities, this article endeavors to conduct a comprehensive scoping review of the existing literature on the most significant ethical implications emanating from genome editing. In conducting this review, we utilized the power of software tools like EndNote and Rayyan to aid in the systematic and thorough review of the literature. EndNote, a reference management software, was instrumental in organizing and managing the references and bibliographies, while Rayyan, a web application designed for managing and screening records for systematic and scoping reviews, proved crucial in the import and management of text records for the review.The review identified as main aspects of ethical, bioethical and medico-legal interest the exacerbation of social inequalities, safety concerns such as off-target mutations and immunological risks, ecological and evolutionary implications, and challenges to human dignity. It highlights the necessity for equitable access, rigorous regulation, and public engagement to address these issues responsibly.The ultimate objective of this article is to underscore the importance of an informed and inclusive dialogue regarding genome editing. Such dialogue is pivotal for fostering responsible innovation in this rapidly advancing field, ensuring that scientific progress aligns with ethical considerations. By presenting a comprehensive examination of the ethical implications of genome editing, we aim to contribute to this ongoing dialogue and promote a balanced and nuanced understanding of this impactful technology.

In response to tire failures and vehicle rollover accidents, most notably those experienced by Ford Explorers with Firestone Tires, the 106th Congress and President Clinton enacted the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act of 2000. Section 13 of the TREAD Act requires vehicle manufacturers to install tire pressure monitoring systems (TPMS) that alert drivers when a tire is significantly under-inflated. This paper first discusses the political economy that ultimately led to the final TREAD Act TPMS regulation. Then, relying on the variation of model-year TPMS introduction, I investigate whether and to what extent TPMS reduces all vehicle fatalities and those associated with tire failure and improper inflation. I find that the introduction of TPMS is associated with just over 11 fewer tire failure-related deaths per year, resulting in a net benefit of −$752 million to −$1,876 million (in $2001) per year. I find no change in the number of tire inflation-related fatalities with the introduction of TPMS.

Cannabis is the most commonly used illicit drug worldwide. In countries with repressive drug policies, the costs of its prohibition plausibly outweigh the benefits. We conduct a cost–benefit analysis of cannabis legalization and regulation in the Czech Republic, taking into consideration alternative scenarios designed using parameters from the known effects of cannabis legalization in selected U.S. states, Canada, and Uruguay. Our analysis focuses on tax revenues, law enforcement costs, the cost of treatment and harm reduction, and the value of Quality Adjusted Life Years (QALYs). Under all the projected scenarios, the identified benefits of legalizing cannabis for personal use exceed the potential costs. The estimated net social benefit of legalization is in the range of 34.4 to 107.6 million EUR per year (or between 3.2 and 10.1 EUR per capita), depending on the size of the cannabis market and the development of cannabis prices after legalization.

The implementation of the General Data Protection Regulation (GDPR) in the EU, rather than the regulation itself, is holding back technological innovation. The EU’s data protection governance architecture is complex, leading to contradictory interpretations among Member States. This situation is prompting companies of all kinds to halt the deployment of transformative projects in the EU. The case of Meta is paradigmatic: both the UK and the EU broadly have the same regulation (GDPR), but the UK swiftly determined that Meta could train its generative AI model using first-party public data under the legal basis of legitimate interest, while in the EU, the European Data Protection Board (EDPB) took months to issue an Opinion that national authorities must still interpret and implement individually, leading to legal uncertainty. Similarly, the case of Deepseek has demonstrated how some national data protection authorities, such as the Italian Garante, have moved to ban the AI model outright, while others have opted for investigations. This fragmented enforcement landscape exacerbates regulatory uncertainty and hampers EU’s competitiveness, particularly for startups, which lack the resources to navigate an unpredictable compliance framework. For the EU to remain competitive in the global AI race, strengthening the EDPB’s role is essential.

This dissertation presents the results of a series of common pool experiments conducted in three regions of rural Colombia with individuals who face a social dilemma in their everyday lives that is similar to what was presented in the experiment. The research objectives are to develop an empirical characterization of how individual behavior deviates from purely self-interested Nash behavior and to further our understanding of the effects of alternative institutions to promote more conservative choices in common pool experiments.

Groups of five subjects participated in a 20-period common pool resource game framed as a harvest decision from a fishery. Every group first played 10 rounds of a baseline limited access common pool resource game and then 10 additional rounds under one of five institutions: face-to-face communication, one of two external regulations, and communication combined with one of the two regulations. The two external regulations consisted of an individual harvest quota that was set at the efficient outcome, but differ with respect to the level of enforcement. A total of 420 individuals participated in the experiments, with individual earnings averaging slightly more than a day's wages. The results are presented in three essays.

The first essay, What Motivates Common Pool Resource Users?, develops and tests several models of pure Nash strategies of individuals who extract from a common pool resource when they are motivated by combinations of self-interest, altruism, reciprocity, inequity aversion or conformity. The results suggest that a model which balances self-interest with a strong preference for conformity best describes average strategies. The data are inconsistent with a model of pure self-interest, as well as models that combine self-interest with individual preferences for altruism, reciprocity and inequity aversion.

The second essay, Communication and Regulation to Conserve Common Pool Resources, tests for interaction effects between formal regulations imposed on a community to conserve a local natural resource and non-binding verbal agreements to do the same. The results indicate that formal regulations and informal communication are mutually reinforcing in some instances, but this result is not robust across regions or regulations. Therefore, the hypothesis of a complementary relationship of formal and informal control of local natural resources cannot be supported in general; instead the effects are likely to be community-specific. There is some evidence to suggest that these effects are correlated with the relative importance of formal regulations versus informal community efforts in the community.

The third essay, Within and Between Group Variation in Individual Strategies in Common Pools, analyzes the relative effects of groups and individuals within groups in explaining variation in individual harvest decisions for particular institutions, and uses a hierarchical linear model to examine how these sources of variation may vary across institutions. Communication serves to effectively coordinate individual strategies within groups, but these coordinated strategies vary considerably among groups. In contrast, externally-imposed regulatory schemes (as well as unregulated limited access) produce significant variation in the individual strategies within groups, but these strategies are roughly replicated across groups so that there is little between-group variation.

The United States is one of the largest consumers of meat globally. The traditional production of meat contributes substantially to climate change due to the levels of greenhouse gases emitted and the amount of land, water, feed, and other natural resources required to raise animals used for meat. Conventional meat production is also a major source for the emergence of zoonotic diseases and antimicrobial-resistant pathogens. Nevertheless, Americans consume more meat now than at any time in the nation’s history.

Advocates for policy change aimed at addressing the risks currently associated with meat production have typically focused on reducing meat consumption, alternatives to meat, or improving the standards of conventional meat production. These are laudable goals, but an emerging technology now promises meat production that may avoid these risks entirely. Enter “lab-grown meat” — meat cultivated in an efficient and controlled laboratory environment without the need for fields, feed, or even animals.

The technology has been in development for over 100 years but has seen exponential growth in the past five years. What was previously considered a science fiction fantasy became a reality in the United States in 2023, when UPSIDE Foods and GOOD Meat received approval from USDA for sale of their cultivated chicken to U.S. consumers.

This article highlights the benefits and drawbacks associated with lab-grown meat, assesses the existing regulatory framework, and offers considerations for policy reform as regulators address the emergence and scale-up of this important technology.
