Global Public Good
In traditional usage, a global public good (or global good) is a public good available on a more-or-less worldwide basis. There are many challenges to the traditional definition, which have far-reaching implications in the age of globalization. Definition In traditional usage, a pure global public good is a good that has the three following properties:Kaul, Inge, Isabelle Grunberg and Marc A. Stern (eds.) (1999). ''Global public goods: international cooperation in the 21st century''. NY: Oxford University Press, Inc.(PDF available.) * It is non-rivalrous. Consumption of this good by anyone does not reduce the quantity available to other agents. * It is non-excludable. It is impossible to prevent anyone from consuming that good. * It is available more-or-less worldwide. This concept is an extension of American economist Paul Samuelson's classic notion of public goods to the economics of globalization. The traditional theoretical concept of public goods does not distinguish wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Good (economics)
In economics, a public good (also referred to as a social good or collective good)Oakland, W. H. (1987). Theory of public goods. In Handbook of public economics (Vol. 2, pp. 485-535). Elsevier. is a good that is both non-excludable and non-rivalrous. For such goods, users cannot be barred from accessing or using them for failing to pay for them. Also, use by one person neither prevents access of other people nor does it reduce availability to others. Therefore, the good can be used simultaneously by more than one person. This is in contrast to a common good, such as wild fish stocks in the ocean, which is non-excludable but rivalrous to a certain degree. If too many fish were harvested, the stocks would deplete, limiting the access of fish for others. A public good must be valuable to more than one user, otherwise, the fact that it can be used simultaneously by more than one person would be economically irrelevant. Capital goods may be used to produce public goods or services t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Policy
The economy of governments covers the systems for setting levels of taxation, government budgets, the money supply and interest rates as well as the labour market, national ownership, and many other areas of government interventions into the economy. Most factors of economic policy can be divided into either fiscal policy, which deals with government actions regarding taxation and spending, or monetary policy, which deals with central banking actions regarding the money supply and interest rates. Such policies are often influenced by international institutions like the International Monetary Fund or World Bank as well as political beliefs and the consequent policies of parties. Types of economic policy Almost every aspect of government has an important economic component. A few examples of the kinds of economic policies that exist include: *Macroeconomic stabilization policy, which attempts to keep the money supply growing at a rate that does not result in excessive inflati ...

Supranational Union
A supranational union is a type of international organization that is empowered to directly exercise some of the powers and functions otherwise reserved to states. A supranational organization involves a greater transfer of or limitation of state sovereignty than other kinds of international organizations. The European Union (EU) has been described as a paradigmatic case of a supranational organization, as it has deep political, economic and social integration, which includes a common market, joint border control, a supreme court, and regular popular elections. Another method of decision-making in international organisations is intergovernmentalism in which state governments play a more prominent role. Origin as a legal concept After the dropping of atomic bombs on Hiroshima and Nagasaki in August 1945, Albert Einstein spoke and wrote frequently in the late 1940s in favour of a "supranational" organization to control all military forces except for local police forces, ...

Global Health
Global health is the health of the populations in the worldwide context; it has been defined as "the area of study, research and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement ( including mental health), reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective. Global health is not to be confused with international health, which is defined as the branch of public health focusing on developing nations and foreign aid efforts by industrialized countries. One way global health can be measured is the prevalence of various global diseases in the world and their threat to decrease life expectancy in the present day. Est ...

Knowledge Production
Knowledge can be defined as awareness of facts or as practical skills, and may also refer to familiarity with objects or situations. Knowledge of facts, also called propositional knowledge, is often defined as true belief that is distinct from opinion or guesswork by virtue of justification. While there is wide agreement among philosophers that propositional knowledge is a form of true belief, many controversies in philosophy focus on justification: whether it is needed at all, how to understand it, and whether something else besides it is needed. These controversies intensified due to a series of thought experiments by Edmund Gettier and have provoked various alternative definitions. Some of them deny that justification is necessary and replace it, for example, with reliability or the manifestation of cognitive virtues. Others contend that justification is needed but formulate additional requirements, for example, that no defeaters of the belief are present or that the ...

Security
" \n\n\nsecurity.txt is a proposed standard for websites' security information that is meant to allow security researchers to easily report security vulnerabilities. The standard prescribes a text file called \"security.txt\" in the well known location, similar in syntax to robots.txt but intended to be machine- and human-readable, for those wishing to contact a website's owner about security issues. security.txt files have been adopted by Google, GitHub, LinkedIn, and Facebook.\n History \n\nThe Internet Draft was first submitted by Edwin Foudil in September 2017. At that time it covered four directives, \"Contact\", \"Encryption\", \"Disclosure\" and \"Acknowledgement\". Foudil expected to add further directives based on feedback. In addition, web security expert Scott Helme said he had seen positive feedback from the security community while use among the top 1 million websites was \"as low as expected right now\".\n\nIn 2019, the Cybersecurity and Infrastructure Security Agency ( ...

Climate Change Mitigation
Climate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly caused by emissions from fossil fuels burning (coal, oil, and natural gas). Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. In addition, can be removed from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes, which are grouped together under the term of carbon sequestration. Solar energy and wind power have the highest climate change mitigation potential at lowest cost compared to a range of other options. Variable availability of sunshine and wind is addressed by energy storage and improved electrical grids, including long-distance electricity transmission, demand management and diversification of renewables. As low-carbon power is more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transnationality
Transnationality is the principle of acting at a geographical scale larger than that of states, so as to take into account the interests of a supranational entity. Transnational policies or programmes are not simply aggregations of national policies or programmes, but seek to submerge these within a greater whole. According to Aihwa Ong, the term differs from that of transnationalism, as transnationalism refers "to the cultural specificities of global processes, tracing the multiplicity of the uses and conceptions of 'culture'" whereas transnationality is "the condition of cultural interconnectedness and mobility across space". Transnationality is practised by organisations such as the United Nations and the European Union. The EU's principle of subsidiarity holds that actions should be carried out at the lowest feasible governmental level, and therefore much scope is left to individual Member States. The EU institutions thus concern themselves principally with transnational po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Rider Problem
In the social sciences, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods (such as public roads or public library), or services of a communal nature do not pay for them or under-pay. Free riders are a problem because while not paying for the good (either directly through fees or tolls or indirectly through taxes), they may continue to access or consume it. Thus, the good may be under-produced, overused or degraded. Additionally, it has been shown that despite evidence that people tend to be cooperative by nature, the presence of free-riders cause this prosocial behaviour to deteriorate, perpetuating the free-rider problem. The free-rider problem in social science is the question of how to limit free riding and its negative effects in these situations. Such an example is the free-rider problem of when property rights are not clearly defined and imposed. The free-rider problem is common with public goods which are ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioac ...

Price
A price is the (usually not negative) quantity of payment or compensation given by one party to another in return for goods or services. In some situations, the price of production has a different name. If the product is a "good" in the commercial exchange, the payment for this product will likely be called its "price". However, if the product is "service", there will be other possible names for this product's name. For example, the graph on the bottom will show some situations A good's price is influenced by production costs, supply of the desired item, and demand for the product. A price may be determined by a monopolist or may be imposed on the firm by market conditions. Price can be quoted to currency, quantities of goods or vouchers. * In modern economies, prices are generally expressed in units of some form of currency. (More specifically, for raw materials they are expressed as currency per unit weight, e.g. euros per kilogram or Rands per KG.) * Although ...

Private Good
A private good is defined in economics as "an item that yields positive benefits to people" that is excludable, i.e. its owners can exercise private property rights, preventing those who have not paid for it from using the good or consuming its benefits; and rivalrous, i.e. consumption by one necessarily prevents that of another. A private good, as an economic resource is scarce, which can cause competition for it. The market demand curve for a private good is a horizontal summation of individual demand curves. Unlike public goods, such as clean air or national defense, private goods are less likely to have the free rider problem, in which a person benefits from a public good without contributing towards it. Assuming a private good is valued positively by everyone, the efficiency of obtaining the good is obstructed by its rivalry; that is simultaneous consumption of a rivalrous good is theoretically impossible. The feasibility of obtaining the good is made difficult by its exclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
