Postgraduate Education
Postgraduate or graduate education refers to Academic degree, academic or professional degrees, certificates, diplomas, or other qualifications pursued by higher education, post-secondary students who have earned an Undergraduate education, undergraduate (Bachelor's degree, bachelor's) degree. The organization and structure of postgraduate education varies in different countries, as well as in different institutions within countries. While the term "graduate school" or "grad school" is typically used in North America, "postgraduate" is often used in countries such as (Australia, Bangladesh, India, Ireland, New Zealand, Pakistan, South Africa, and the UK). Graduate degrees can include master's degree, master's degrees, doctorate, doctoral degrees, and other qualifications such as graduate certificates and professional degrees. A distinction is typically made between graduate schools (where courses of study vary in the degree to which they provide training for a particular profe ...

Freshman
A freshman, fresher, first year, or frosh, is a person in the first year at an educational institution, usually a secondary school or at the college and university level, but also in other forms of post-secondary educational institutions. Arab world In much of the Arab world, a first-year is called a "Ebtidae" (Pl. Mubtadeen), which is Arabic for "beginner". Brazil In Brazil, students that pass the vestibulares and begin studying in a college or university are called "calouros" or more informally "bixos" ("bixetes" for girls), an alternate spelling of "bicho", which means "animal" (although commonly used to refer to bugs). Calouros are often subject to hazing, which is known as "trote" (lit. "prank") there. The first known hazing episode in Brazil happened in 1831 at the Law School of Olinda and resulted in the death of a student. In 1999, a Chinese Brazilian calouro of the University of São Paulo Medicine School named Edison Tsung Chi Hsueh was found dead at the institutio ...

BBVA Foundation Frontiers Of Knowledge Award
The BBVA Foundation Frontiers of Knowledge Awards () are an international award programme recognizing significant contributions in the areas of scientific research and cultural creation. The categories that make up the Frontiers of Knowledge Awards respond to the knowledge map of the present age. As well as the fundamental knowledge that is at their core, they address developments in information and communication technologies, and interactions between biology and medicine, ecology and conservation biology, climate change, economics, humanities and social sciences, and, finally, contemporary musical creation and performance. Specific categories are reserved for developing knowledge fields of critical relevance to confront central challenges of the 21st century, as in the case of the two environmental awards. The awards were established in 2008, with the first set of winners receiving their prizes in 2009. The BBVA Foundation – belonging to financial group BBVA – is partnered in t ...

Léon Walras
Marie-Esprit-Léon Walras (; 16 December 1834 – 5 January 1910) was a French mathematical economist and Georgist. He formulated the marginal theory of value (independently of William Stanley Jevons and Carl Menger) and pioneered the development of general equilibrium theory. Walras is best known for his book ''Éléments d'économie politique pure'', a work that has contributed greatly to the mathematization of economics through the concept of general equilibrium. The definition of the role of the entrepreneur found in it was also taken up and amplified by Joseph Schumpeter. For Walras, exchanges only take place after a Walrasian '' tâtonnement'' (French for "trial and error"), guided by the auctioneer, has made it possible to reach market equilibrium. It was the general equilibrium obtained from a single hypothesis, rarity, that led Joseph Schumpeter to consider him "the greatest of all economists". The notion of general equilibrium was very quickly adopted by major economi ...

Sonnenschein–Mantel–Debreu Theorem
The Sonnenschein–Mantel–Debreu theorem is an important result in general equilibrium economics, proved by Gérard Debreu, , and Hugo F. Sonnenschein in the 1970s. It states that the excess demand curve for an exchange economy populated with utility-maximizing rational agents can take the shape of any function that is continuous, has homogeneity degree zero, and is in accordance with Walras's law. This implies that the excess demand function does not take a well-behaved form even if each agent has a well-behaved utility function. Market processes will not necessarily reach a unique and stable equilibrium point. More recently, Jordi Andreu, Pierre-André Chiappori, and Ivar Ekeland extended this result to market demand curves, both for individual commodities and for the aggregate demand of an economy as a whole. This means that demand curves may take on highly irregular shapes, even if all individual agents in the market are perfectly rational. In contrast with usual assum ...

General Equilibrium Theory
In economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts to the theory of ''partial'' equilibrium, which analyzes a specific part of an economy while its other factors are held constant. In general equilibrium, constant influences are considered to be noneconomic, therefore, resulting beyond the natural scope of economic analysis. The noneconomic influences is possible to be non-constant when the economic variables change, and the prediction accuracy may depend on the independence of the economic factors. General equilibrium theory both studies economies using the model of equilibrium pricing and seeks to determine in which circumstances the assumptions of general equilibrium will hold. The theory dates to the 1870s, particularly t ...
