prime rate

(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).

Eurostat

(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!

(US GOVERNMENT) bureau within the federal government of the United States; part of the Department of Labor. Measures unemployment, hours worked, hourly wages, inflation, productivity, and so on.

The Department of Labor was created as a result of the NLRA (1935), which gave workers the right to organize.
Yesterday the Bureau of Labor Statistics (BLS) published its monthly report of hours worked. This revealed that, while employees are working more hours, unemployment has not declined and wages continue to decline.

logarithm

(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.
A logarithm is the inverse of an exponential function.

Greenspan put

(FINANCE) the widely-held belief by most traders or speculators that Federal Reserve Chairman Alan Greenspan (s.1987 to 2006) would use monetary policy to ensure that asset prices would not fall below a certain level.

A "put" here refers to the put option, a financial derivative that allows the owner the guaranteed right to sell a fixed amount of the underlying asset for a fixed strike price. A person who has a put for the assets she owns therefore is immune from the risk of those assets falling below a particular floor.

In the case of the Greenspan put, it was widely observed that Greenspan intervened in order to protect gains in asset values; this tended to guarantee that purchases of financial assets during Greenspan's tenure were very unlikely to be mistakes. This, of course, created conditions of moral hazard in the asset markets. particularly in financial stocks and in housing prices.
The outcome of that (October 1994) rate cut turned out to be far worse, as the committee's actions came to be viewed as the Greenspan Put, meaning speculators could take enormous amounts of risk trusting that Greenspan would do anything to stop the market from a serious decline.

financial derivative

(FINANCE) a financial instrument whose value is tied to something else; for example,

* a futures contract (future)

* an option

* a swap

In each of these examples, the value of the derivative is related in some way to the price of something else. When the market price of (say) an ounce of gold goes from $1000/oz to $1050/oz, the return to the owner of 1 oz. of actual gold is 5%. But for the owner of a call option or a future, the return is much, much greater than that.

A derivative can be used to multiply risk AND potential profits to speculators; but it can be used for the counterparty to minimize risk by locking in prices, or by hedging against risk.
The economic crisis of 2008 has really focused attention on the financial derivative market.

in the money

(FINANCE) when a financial derivative has intrinsic value to the person who holds it. There are two examples:

* when the strike price of a call option is less than the spot price of the underlying stock, it is worthwhile to exercise it;

* when the strike price of a put option is more than the spot price of the underlying stock, it is worthwhile to exercise it.

Please remember that an option being "in the money" does not mean it was a good investment. You might have bought the option when the difference between the strike price and the spot price was MORE than it is now. If it's expiring, you might as well exercise it because to not do so is just throwing money away. But it still could have been a loss for the investor.
PHIL: Sweet! My call options are back in the money. Now I'd better exercise them.

MIGUEL: You must be rolling in the cash, Holmes!

PHIL: Not even close. The forex rate for the UK pound nosedived and I got hosed pretty bad. It's not where it was when I bought these rat droppings, but I need to get out before they expire.

MIGUEL: You know, when you first told me about options they sounded like a sweet deal, but...

PHIL: Yeah... the guy who wrote the option always seems to know what's going down better than us dilettantes.
