String instrumentString instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner. Musicians play some string instruments by plucking the strings with their fingers or a plectrum—and others by hitting the strings with a light wooden hammer or by rubbing the strings with a bow. In some keyboard instruments, such as the harpsichord, the musician presses a key that plucks the string.
Economic analysis of climate changeThe economic analysis of climate change explains how economic thinking, tools and techniques are applied to calculate the magnitude and distribution of damage caused by climate change. It also informs the policies and approaches for mitigation and adaptation to climate change from global to household scales. This topic is also inclusive of alternative economic approaches, including ecological economics and degrowth. Economic analysis of climate change is considered challenging as it is a long-term problem and has substantial distributional issues within and across countries.
X-inefficiencyX-inefficiency - is a concept used in economics to describe instances where firms go through internal inefficiency resulting in higher production costs than required for a given output. This inefficiency is a result of various factors such as outdated technology, Inefficient production processes, poor management and lack of competition resulting in lower profits and higher prices for consumers. The concept of X-inefficiency was introduced by Harvey Leibenstein. The difference between the potential and actual cost is known as X-Inefficiency.
Wealth taxA wealth tax (also called a capital tax or equity tax) is a tax on an entity's holdings of assets or an entity's net worth. This includes the total value of personal assets, including cash, bank deposits, real estate, assets in insurance and pension plans, ownership of unincorporated businesses, financial securities, and personal trusts (a one-off levy on wealth is a capital levy). Typically, wealth taxation often involves the exclusion of an individual's liabilities, such as mortgages and other debts, from their total assets.
Universal basic incomeUniversal basic income (UBI) is a social welfare proposal in which all citizens of a given population regularly receive a guaranteed income in the form of an unconditional transfer payment (i.e., without a means test or need to work). It would be received independently of any other income. If the level is sufficient to meet a person's basic needs (i.e., at or above the poverty line), it is sometimes called a full basic income; if it is less than that amount, it may be called a partial basic income.
Tax incidenceIn economics, tax incidence or tax burden is the effect of a particular tax on the distribution of economic welfare. Economists distinguish between the entities who ultimately bear the tax burden and those on whom the tax is initially imposed. The tax burden measures the true economic effect of the tax, measured by the difference between real incomes or utilities before and after imposing the tax, and taking into account how the tax causes prices to change.
The Wealth of NationsAn Inquiry into the Nature and Causes of the Wealth of Nations, generally referred to by its shortened title The Wealth of Nations, is the magnum opus of the Scottish economist and moral philosopher Adam Smith (1723-1790). First published in 1776, the book offers one of the world's first connected accounts of what builds nations' wealth, and has become a fundamental work in classical economics. Reflecting upon economics at the beginning of the Industrial Revolution, Smith addresses topics such as the division of labour, productivity, and free markets.
Stackelberg competitionThe Stackelberg leadership model is a strategic game in economics in which the leader firm moves first and then the follower firms move sequentially (hence, it is sometimes described as the "leader-follower game"). It is named after the German economist Heinrich Freiherr von Stackelberg who published Marktform und Gleichgewicht [Market Structure and Equilibrium] in 1934, which described the model. In game theory terms, the players of this game are a leader and a follower and they compete on quantity.
Member state of the European UnionThe European Union (EU) is a political and economic union of 27 member states that are party to the EU's founding treaties, and thereby subject to the privileges and obligations of membership. They have agreed by the treaties to share their own sovereignty through the institutions of the European Union in certain aspects of government. State governments must agree unanimously in the Council for the union to adopt some policies; for others, collective decisions are made by qualified majority voting.
European Economic AreaThe European Economic Area (EEA) was established via the Agreement on the European Economic Area, an international agreement which enables the extension of the European Union's single market to member states of the European Free Trade Association. The EEA links the EU member states and three EFTA states (Iceland, Liechtenstein, and Norway) into an internal market governed by the same basic rules. These rules aim to enable free movement of persons, goods, services, and capital within the European single market, including the freedom to choose residence in any country within this area.
