Minimum wageA minimum wage is the lowest remuneration that employers can legally pay their employees—the price floor below which employees may not sell their labor. Most countries had introduced minimum wage legislation by the end of the 20th century. Because minimum wages increase the cost of labor, companies often try to avoid minimum wage laws by using gig workers, by moving labor to locations with lower or nonexistent minimum wages, or by automating job functions.
Living wageA living wage is defined as the minimum income necessary for a worker to meet their basic needs. This is not the same as a subsistence wage, which refers to a biological minimum, or a solidarity wage, which refers to a minimum wage tracking labor productivity. Needs are defined to include food, housing, and other essential needs such as clothing. The goal of a living wage is to allow a worker to afford a basic but decent standard of living through employment without government subsidies.
Human migrationHuman migration is the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is also possible; indeed, this is the dominant form of human migration globally. Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move.
Environmental securityEnvironmental security examines threats posed by environmental events and trends to individuals, communities or nations. It may focus on the impact of human conflict and international relations on the environment, or on how environmental problems cross state borders. The Millennium Project assessed definitions of environmental security and created a synthesis definition: Environmental security is environmental viability for life support, with three sub-elements: preventing or repairing military damage to the environment, preventing or responding to environmentally caused conflicts, and protecting the environment due to its inherent moral value.
Circular migrationCircular migration or repeat migration is the temporary and usually repetitive movement of a migrant worker between home and host areas, typically for the purpose of employment. It represents an established pattern of population mobility, whether cross-country or rural-urban. There are several benefits associated with this migration pattern, including gains in financial capital, human capital, and social capital. There are also costs associated with circular migration, such as brain drain, poor working conditions, forced labor, and the inability to transfer acquired skills to home economies.
