Golden AgeThe term Golden Age comes from Greek mythology, particularly the Works and Days of Hesiod, and is part of the description of temporal decline of the state of peoples through five Ages, Gold being the first and the one during which the Golden Race of humanity (χρύσεον γένος chrýseon génos) lived. After the end of the first age was the Silver, then the Bronze, after this the Heroic age, with the fifth and current age being Iron. By extension, "Golden Age" denotes a period of primordial peace, harmony, stability, and prosperity.
Golden age (metaphor)A golden age is a period considered the peak in the history of a country or people, a time period when the greatest achievements were made. The term originated from early Greek and Roman poets, who used it to refer to a time when mankind lived in a better time and was pure (see Golden Age). The ancient Greek poet Hesiod introduced the term in his Works and Days, when referring to the period when the "Golden Race" of man lived.
Insider tradingInsider trading is the trading of a public company's stock or other securities (such as bonds or stock options) based on material, nonpublic information about the company. In various countries, some kinds of trading based on insider information are illegal. This is because it is seen as unfair to other investors who do not have access to the information, as the investor with insider information could potentially make larger profits than a typical investor could make.
Age of EnlightenmentThe Age of Enlightenment or the Enlightenment, also known as the Age of Reason, was an intellectual and philosophical movement that occurred in Europe, especially Western Europe, in the 17th and 18th centuries, with global influences and effects. The Enlightenment included a range of ideas centered on the value of human happiness, the pursuit of knowledge obtained by means of reason and the evidence of the senses, and ideals such as natural law, liberty, progress, toleration, fraternity, constitutional government, and separation of church and state.
Problem of inductionFirst formulated by David Hume, the problem of induction questions our reasons for believing that the future will resemble the past, or more broadly it questions predictions about unobserved things based on previous observations. This inference from the observed to the unobserved is known as "inductive inferences", and Hume, while acknowledging that everyone does and must make such inferences, argued that there is no non-circular way to justify them, thereby undermining one of the Enlightenment pillars of rationality.
Influential observationIn statistics, an influential observation is an observation for a statistical calculation whose deletion from the dataset would noticeably change the result of the calculation. In particular, in regression analysis an influential observation is one whose deletion has a large effect on the parameter estimates. Various methods have been proposed for measuring influence. Assume an estimated regression , where is an n×1 column vector for the response variable, is the n×k design matrix of explanatory variables (including a constant), is the n×1 residual vector, and is a k×1 vector of estimates of some population parameter .
Cook's distanceIn statistics, Cook's distance or Cook's D is a commonly used estimate of the influence of a data point when performing a least-squares regression analysis. In a practical ordinary least squares analysis, Cook's distance can be used in several ways: to indicate influential data points that are particularly worth checking for validity; or to indicate regions of the design space where it would be good to be able to obtain more data points. It is named after the American statistician R.
1997 Asian financial crisisThe 1997 Asian financial crisis was a period of financial crisis that gripped much of East and Southeast Asia during the late 1990s. The crisis began in Thailand in July 1997 before spreading to several other countries with a ripple effect, raising fears of a worldwide economic meltdown due to financial contagion. However, the recovery in 1998–1999 was rapid, and worries of a meltdown quickly subsided.
Fuel price risk managementFuel price risk management, a specialization of both financial risk management and oil price analysis and similar to conventional risk management practice, is a continual cyclic process that includes risk assessment, risk decision making and the implementation of risk controls. It focuses primarily on when and how an organization can best hedge against exposure to fuel price volatility. It is generally referred to as "bunker hedging" in marine and shipping contexts and "fuel hedging" in aviation and trucking contexts.
Exchange-traded fundAn exchange-traded fund (ETF) is a type of investment fund and exchange-traded product, i.e. they are traded on stock exchanges. ETFs own financial assets such as stocks, bonds, currencies, futures contracts, and/or commodities such as gold bars. The list of assets that each ETF owns, as well as their weightings, is posted on the website of the issuer daily, or quarterly in the case of active non-transparent ETFs. Many ETFs provide some level of diversification compared to owning an individual stock.
