factors of production

*noun*; term coined by Adam Smith (1723-1790) to refer to things used to produce other things. Usually people refer to four factors of production:
1.labor (not the same thing as workers); a worker can work more or less hours per week, and can exchange her labor for payment
2. capital; includes tools, machinery, plants and fixtures, seed corn, etc. Adam Smith distinguished between inventories, which he called circulating capital, and tools, which he called fixed capital;
3. land; understood as a specific area on the earth's surface, but sometimes incorporates the natural productivity or mineral resources as well;
4. entrepreneurship; sometimes lumped with capital. Includes the combination of skills required to start a business.
Different economic systems vary in their view of who should own the factors of production. In capitalism, this would be private individuals; in communism, it would be a collective. In the Marxist transition to communism, it would be the state.

square root

(MATHEMATICS) each positive number has another number that, when multiplied times itself, equals that number. So, for example, 4 has a square root of 2 (2 x 2 = 4).

The square root of a negative number is an imaginary number. Imaginary numbers are not, by themselves, useful solutions to math problems; but they can be used to find them.
BILL: Anna, we have a rectangle that's 3 x as long as it is wide, and it encloses an area of 300 square meters. What are the dimensions?

ANNA: Well, that's like 3 squares of 100 square meters. The square root of 100 is 10, so the rectangle is 10 by 30.

_________________________________________

The logarithm of a square root is one half the log of the number itself; hence, the natural log of 25 is 3.2189, while the natural log of 5 is 1.6094.

NLRA

(US HISTORY) National Labor Relations Act (Wagner Act); 1935 law that permitted most US workers to form labor unions. It created the National Labor Relations Board to enforce this right. Named for Sen. Robert F. Wagner (D-NY).

The NLRB conducts secret-ballot elections to determine whether employees want union representation and also investigates unlawful labor practices by employers and unions. The act guarantees employees the right to organize, choose representatives, and bargain collectively. The NLRB regulates all employers involved in interstate commerce other than transport, agriculture, and government.
The NLRA was probably the most important single piece of New Deal legislation.

diminishing marginal returns

phenomenon in which greater input of effort, money, etc. yields smaller results. Crucial part of the idea is that if you're using x to get y results (where y is the thing you want). then additional input a will yield additional results b, but not in the same proportion as before.

On average, before, you put in x to get y, so your yield was y/x. But if you increase x by amount a, then your results will be y + b, where

(y + b)/(x + a) < y/x

and this will only get worse.

Diminishing marginal returns (DMR) is used to explain why the supply curve in economics slopes upward, i.e., increasing the quantity supplied requires an increased price of most things.

Sometimes DMR is more than offset by "economies of scale," which allows more of a thing to be supplied more cheaply than a small amount.
At first his flowers and treats swept her off her feet, but then he had to do more and more lavish things to please her. It was a classic case of diminishing marginal returns.

PE fund

(FINANCE) private equity fund; business entity formed to pool money provided by investors in order to buy majority stakes in existing companies. A common practice is to then "take the company private," so that it no longer has shares trading on the stock market. The company is then restructured, so that it has entirely different management practices, or a different business strategy. Afterward, the PE fund will most likely re-sell the company on the stock market in a sponsored IPO.

PE funds are usually limited partnerships (LPs), which gives them special privileges of nondisclosure; most are organized in the State of Delaware. PEF's have sponsors, or "principals," who are responsible for organizing the fund and recruiting other investors. They are never "limited liability partnerships" (LLP's); apologies to Urban Dictionary for erroneously mixing them up in my definition for "private equity fund" and "hedge fund." The difference between the two is explained there.

Among the best-known PE funds are Blackstone Group*, Kohlberg Kravis Roberts (KKR)*, Goldman Sachs Capital Partners*, Carlyle Group, Permira, Apollo Management, Providence Equity, TPG Capital, Warburg Pincus, and Cerberus. Companies marked with an asterisk (*) are publicly listed corporations; most PE funds are privately managed. The selection above includes the largest ones by capital under management.
The PE fund first appeared in the 1970's as a result of changes to ERISA. Institutional investors, usually pension funds, could be legal partners in an LP; they also required a place to park assets with very high rates of return.

In the USA, PE funds have long been sinecures for the most powerful political dynasties: the Rockefellers, the Romneys, the Bushes, and others.

fresh water school

*noun*, term used in economics to refer to the New Classical economics. The fresh water school was lead by Robert E. Lucas, Thomas J. Sargent, and Robert Barro; its position was that fiscal policy and monetary policy are doomed to be ineffective, since they rely on "fooling the public."

Instead, they argued that even tax cuts had no stimulus effect (in contrast to "supply side economics"), and of course they were resolutely opposed to government spending. Instead, the fresh water school maintained that a recession was caused by markets adjusting to a technology shock to create a structurally different economic system. The best thing to do was to allow the markets to restructure industry on their own.

The fresh water school was known for their support of the "rational expectations hypothesis" (REH) and "real business cycle" (RBC) theory.
But lately, a ...school of skeptics who think the Government usually just gums things up is gaining attention and influence. The skeptics are known as the "fresh water school," less for the purity of their thought than for their origins at universities along the shores of the Great Lakes.
