Tail risks include low-probability events arising at both ends of a normal distribution curve, also known as tail events. [1]
The former definition may not be a coherent risk measure in general, however it is coherent if the underlying distribution is continuous. [4] The latter definition is a coherent risk measure. [3] TVaR accounts for the severity of the failure, not only the chance of failure. The TVaR is a measure of the expectation only in the tail of the ...
Expected shortfall (ES) is a risk measure—a concept used in the field of financial risk measurement to evaluate the market risk or credit risk of a portfolio. The "expected shortfall at q% level" is the expected return on the portfolio in the worst % of cases.
"Prior acts" (or "nose") coverage transfers the retro-active date for an old policy to a new insurance carrier—eliminating the need to purchase tail coverage from the last carrier. Nose coverage is usually less expensive than purchasing tail coverage from the old carrier. Tail coverage costs 2–3 times the expiring premium.
Interest coverage ratio, or ICR, is used to evaluate a company’s ability to pay the interest it owes on its debts. There is no generally agreed upon standard for what makes a healthy ICR across ...
In statistical estimation theory, the coverage probability, or coverage for short, is the probability that a confidence interval or confidence region will include the true value (parameter) of interest. It can be defined as the proportion of instances where the interval surrounds the true value as assessed by long-run frequency.
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
Financial economics is the branch of economics characterized by a "concentration on monetary activities", in which "money of one type or another is likely to appear on both sides of a trade". [1] Its concern is thus the interrelation of financial variables, such as share prices, interest rates and exchange rates, as opposed to those concerning ...
