Chicago School Of Economics
The Chicago school of economics is a Neoclassical economics, neoclassical Schools of economic thought, school of economic thought associated with the work of the faculty at the University of Chicago, some of whom have constructed and popularized its principles. Milton Friedman and George Stigler are considered the leading scholars of the Chicago school. Chicago macroeconomic theory rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. The Saltwater and freshwater economics, freshwater–saltwater distinction is largely antiquated today, as the two traditions have heavily incorporated ideas from each other. Specifically, new Keynesian economics was developed as a response to new classical economics, electing to incorporate the insight of rational expectations without giving up the traditional Keynesian focus on imperfect competition and sticky wages.

Present Value
In economics and finance, present value (PV), also known as present discounted value (PDV), is the value of an expected income stream determined as of the date of valuation. The present value is usually less than the future value because money has interest-earning potential, a characteristic referred to as the time value of money, except during times of negative interest rates, when the present value will be equal or more than the future value. Time value can be described with the simplified phrase, "A dollar today is worth more than a dollar tomorrow". Here, 'worth more' means that its value is greater than tomorrow. A dollar today is worth more than a dollar tomorrow because the dollar can be invested and earn a day's worth of interest, making the total accumulate to a value more than a dollar by tomorrow. Interest can be compared to Renting, rent. Just as rent is paid to a landlord by a tenant without the ownership of the asset being transferred, interest is paid to a lender by ...

Alfred Cowles
Alfred Cowles III (September 15, 1891 – December 28, 1984) was an American economist, businessman, and founder of the Cowles Commission for Research in Economics, an influential research institute which advanced the field of econometrics in the 20th century. When he established the Cowles Commission in 1932, he was intent on making economics more of a "science" by collecting data and applying modern mathematical and statistical techniques. Although he shared the same name as his father and grandfather, both of whom had been involved with the Chicago Tribune Company'','' he preferred to be known simply as Alfred Cowles. Early life and education Born on September 15, 1891, Alfred's family members called him "Bob".

Cowles Commission For Research In Economics
The Cowles Foundation for Research in Economics is an economic research institute at Yale University. History It was created as the Cowles Commission for Research in Economics at Colorado Springs in 1932 by businessman and economist Alfred Cowles. In 1939, the Cowles Commission moved to the University of Chicago under Theodore O. Yntema. Jacob Marschak directed it from 1943 until 1948, when Tjalling C. Koopmans assumed leadership. Increasing opposition to the Cowles Commission from the department of economics of the University of Chicago during the 1950s impelled Koopmans to persuade the Cowles family to move the commission to Yale University in 1955 where it became the Cowles Foundation. As its motto ''Theory and Measurement'' implies, the Cowles Commission focuses on linking economic theory to mathematics and statistics. Its advances in economics involved the creation and integration of general equilibrium theory and econometrics. The thrust of the Cowles approach was a sp ...

David Hume
David Hume (; born David Home; – 25 August 1776) was a Scottish philosopher, historian, economist, and essayist who was best known for his highly influential system of empiricism, philosophical scepticism and metaphysical naturalism. Beginning with '' A Treatise of Human Nature'' (1739–40), Hume strove to create a naturalistic science of man that examined the psychological basis of human nature. Hume followed John Locke in rejecting the existence of innate ideas, concluding that all human knowledge derives solely from experience. This places him with Francis Bacon, Thomas Hobbes, John Locke, and George Berkeley as an empiricist. Cranston, Maurice, and Thomas Edmund Jessop. 2020 999br>David Hume" ''Encyclopædia Britannica''.

American Jews
American Jews (; ) or Jewish Americans are American citizens who are Jewish, whether by culture, ethnicity, or religion. According to a 2020 poll conducted by Pew Research, approximately two thirds of American Jews identify as Ashkenazi, 3% identify as Sephardic, and 1% identify as Mizrahi. An additional 6% identify as some combination of the three categories, and 25% do not identify as any particular category. During the colonial era, Sephardic Jews who arrived via Portugal and via Brazil ( Dutch Brazil) – see Congregation Shearith Israel – represented the bulk of America's then small Jewish population. While their descendants are a minority nowadays, they represent the remainder of those original American Jews along with an array of other Jewish communities, including more recent Sephardi Jews, Mizrahi Jews, Beta Israel-Ethiopian Jews, various other Jewish ethnic groups, as well as a smaller number of gerim (converts). The American Jewish community manifests a wide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diversification (finance)
In finance, diversification is the process of allocating capital in a way that reduces the exposure to any one particular asset or risk. A common path towards diversification is to reduce financial risk, risk or volatility (finance), volatility by investment, investing in a variety of assets. If asset prices do not change in perfect synchrony, a diversified Portfolio (finance), portfolio will have less variance than the weighted mean, weighted average variance of its constituent assets, and often less volatility than the least volatile of its constituents. Diversification is one of two general techniques for reducing investment risk. The other is hedge (finance), hedging. Examples The simplest example of diversification is provided by the proverb "Don't put all your eggs in one basket". Dropping the basket will break all the eggs. Placing each egg in a different basket is more diversified. There is more risk of losing one egg, but less risk of losing all of them. On the other h ...

Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are '' linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However, in g ...

Return (finance)
In finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows (or securities, or other investments) which the investor receives from that investment over a specified time period, such as interest payments, coupons, cash dividends and stock dividends. It may be measured either in absolute terms (e.g., dollars) or as a percentage of the amount invested. The latter is also called the holding period return. A loss instead of a profit is described as a '' negative return'', assuming the amount invested is greater than zero. To compare returns over time periods of different lengths on an equal basis, it is useful to convert each return into a return over a period of time of a standard length. The result of the conversion is called the rate of return. Typically, the period of time is a year, in which case the rate of return is also called the annualized return, and the conversion process, described below, is called ''annualiz ...

Risk
In simple terms, risk is the possibility of something bad happening. Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. Many different definitions have been proposed. One ISO standard, international standard definition of risk is the "effect of uncertainty on objectives". The understanding of risk, the methods of assessment and management, the descriptions of risk and even the definitions of risk differ in different practice areas (business, economics, Environmental science, environment, finance, information technology, health, insurance, safety, security, security, privacy, etc). This article provides links to more detailed articles on these areas. The international standard for risk management, ISO 31000, provides principles and general guidelines on managing risks faced by organizations. Defi ...
