(MATHEMATICS) a function of numbers that are the root of a base. For example, log(base 2) means a function of numbers that are the numbered roots of 2. The log(base 2) of 2 is 1, meaning 2 raised to the power of 1 is 2 (2^1 = 2); log(2) of 4 is 2, and so on.
The idea here is that any number can be expressed as 2 raised to some power; better still, if you do math with the logs of a number rather than the numbers themselves, you can find useful patterns. For example, if you are graphing population growth, and you just plot the raw number of people over time, you aren't going to notice anything in particular. If you plot the log of population, you can see that, while population is growing, the rate of growth is falling.
Usually, if you are doing statistical research with numbers that always have to be positive (like population, death tolls from diseases, etc.), you need to use logarithms for the numerical values in order to represent a confidence interval.
Logs usually have a base of e or 10. Logs with a base of e are called natural logs.

Get the logarithmmug. (EU GOVERNMENT) agency of the European Union that publishes harmonized statistics for the 27 member states of the EU. The EU does not collect the statistics, but reviews and edits statistics collected by its member states so that the data is comparable for all of the countries in it.
BILL: I'm blogging about the economy of Europe, but I don't know what the economic indicators are. You know, the unemployment rate, the inflation rate, hours worked, and so on.
ANNA: Go to the Eurostat web page. It's really awesome!

Get the Eurostatmug. (ECONOMICS) the lowest interest rate available to non-financial borrowers.
Banks can borrow money from the Federal Reserve System or each other at the lower federal funds rate--and they borrow money from depositors at lower rates still.

The most widely-quoted estimate of the prime rate is that published by the Wall Street Journal (from a survey of the 30 largest banks).

Get the prime ratemug. *noun*; in Keynesian economics, the rate at which aggregate consumption rises in response to a rise in national income.
For example, suppose the marginal propensity to consume (MPC) is 0.95. If the national income is 100 billion dollars, and it rises 10%, then consumption will rise by 9.5 billion, and saving will rise by 0.5 billion.
If this theory is correct, then an expanding economy will suffer insufficient demand for its own output, and a recession will be inevitable.
This is why national governments respond to recessions with deficit spending: they are trying to counteract the MPC's effect on aggregate demand, and bring it in line with potential output.

Not only is the marginal propensity to consume weaker in a wealthy community, but, owing to its accumulation of capital being already larger, the opportunities for further investment are less attractive...

Get the marginal propensity to consume mug. (FINANCE) an amount of precious metals, silver, cash, or other thing of value that a bank keeps in storage to meet unexpected liabilities.
Banks generally accept deposits and lend out money. The deference between the rate of interest paid out to deposits, and the rate of interest required for loans, is called "the spread"; it is the bank's source of income.
Banks are not allowed to lend out 100% of the money they receive as deposits; if they did, then depositors would be unable to take money out of the bank. On the other hand, the bank has to lend most of the money out, since it needs the income earned from interest on loans. Throughout the history of the Usonian banking system, the US states or the federal government have had rules about interest rates, reserves, and financial accounting used by banks.
Since Aldrich-Vreeland Act (1908), banks have been allowed to hold deposits with the US Treasury, then (after 1913) with the Federal Reserve System. Deposits in the FRS do not earn interest, but the reserve banks permit member banks to borrow if they fall short of the reserve requirements (see federal funds rate)

Bank reserves serve two purposes: they allow banks to pay depositors on demand, and they play a role in monetary policy.

Get the bank reservesmug. (FINANCE) borrowing securities for immediate sale, in anticipation of a sharp decline. Short selling requires strong nerves and excellent market timing; it also requires the ability to locate tranches of securities to borrow. If the short seller is correct, then she can buy back the securities at a much lower price, and lock in very high profits with very little initial investment.
Closely related to the concept of a short position. However, a short position includes buying put options (for example), while a long position could include short selling put options. So they are not exactly the same.
If a short sellers are wrong about the market, they are left hastily covering shorts, or buying the item they borrowed at a HIGHER price than they sold it for.

Jim Fisk was a master of the short squeeze; he appeared to cooperate with short selling until he was able to call in loans, forcing his counterparties to cover their shorts.

Get the short sellingmug. (JOURNALISM) using flattery to gain access to sources. The phrase is usually used in the context of White House or Congressional press corps, who use fulsome praise of high-ranking officials whose favor they need. Usually, officials like to be publicly represented as magnificent, selfless, tireless public servants; in exchange for such blurbs, they may invite specific reporters to exclusive events, thereby boosting the reporter's status.
It's actually been a feature of the business press for ages.

Since the financial crisis of 2008, business reporters have tended to write dismissively of bank executives. Six years ago they were likely to have written a beat sweetener about some CEO who was now shithead-of-the week.
