Definition of economic components model

economic components model

Abrams’ model for calculating DLOM based on the interaction of discounts from four economic components.
This model consists of four components: the measure of the economic impact of the delay-to-sale, monopsony power to buyers, and incremental transactions costs to both buyers and sellers.

Arbitrage-free option-pricing models

Yield curve option-pricing models.

Asset pricing model

A model for determining the required rate of return on an asset.

Asset pricing model

A model, such as the Capital Asset Pricing model (CAPM), that determines the required
rate of return on a particular asset.

Binomial model

A method of pricing options or other equity derivatives in
which the probability over time of each possible price follows a binomial
distribution. The basic assumption is that prices can move to only two values
(one higher and one lower) over any short time period.

possible, discrete values in the next time period for each value that it can take on in the preceding time period.

Black-Scholes model

options, developed by Fischer Black and Myron Scholes. It examines market
price, strike price, volatility, time to expiration, and interest rates. It is limited
to only certain kinds of options.

Black-Scholes option-pricing model

A model for pricing call options based on arbitrage arguments that uses
the stock price, the exercise price, the risk-free interest rate, the time to expiration, and the standard deviation
of the stock return.

Capital asset pricing model (CAPM)

An economic theory that describes the relationship between risk and
expected return, and serves as a model for the pricing of risky securities. The CAPM asserts that the only risk
that is priced by rational investors is systematic risk, because that risk cannot be eliminated by diversification.
The CAPM says that the expected return of a security or a portfolio is equal to the rate on a risk-free security
plus a risk premium.

Capital Asset Pricing Model (CAPM)

A model for estimating equilibrium rates of return and values of
assets in financial markets; uses beta as a measure of asset risk
relative to market risk

capital asset pricing model (CAPM)

Theory of the relationship between risk and return which states that the expected risk
premium on any security equals its beta times the market risk premium.

The real flow of cash that a firm could pay out forever in the absence of any change in
the firm's productive capacity.

Economic exposure

The extent to which the value of the firm will change because of an exchange rate change.

Economic income

Cash flow plus change in present value.

the creation of multi-country markets
by developing transnational rules that reduce the fiscal and
physical barriers to trade as well as encourage greater economic
cooperation among countries

Order size that minimizes total inventory costs.

Economic order quantity (EOQ)

The order quantity that minimizes total inventory costs.

economic order quantity (EOQ)

an estimate of the number
of units per order that will be the least costly and provide
the optimal balance between the costs of ordering
and the costs of carrying inventory

economic production run (EPR)

an estimate of the number
of units to produce at one time that minimizes the total
costs of setting up production runs and carrying inventory

Economic rents

Profits in excess of the competitive level.

Economic risk

In project financing, the risk that the project's output will not be salable at a price that will
cover the project's operating and maintenance costs and its debt service requirements.

Economic surplus

For any entity, the difference between the market value of all its assets and the market
value of its liabilities.

Economic union

An agreement between two or more countries that allows the free movement of capital,
labor, all goods and services, and involves the harmonization and unification of social, fiscal, and monetary
policies.

Economic Value Added (EVA)

Operating profit, adjusted to remove distortions caused by certain accounting rules, less a charge
to cover the cost of capital invested in the business.

economic value added (EVA)

a measure of the extent to which income exceeds the dollar cost of capital; calculated
as income minus (invested capital times the cost of capital percentage)

economic value added (EVA)

Term used by the consulting firm Stern Stewart for profit remaining after deduction of the cost
of the capital employed.

economically reworked

when the incremental revenue from the sale of reworked defective units is greater than
the incremental cost of the rework

Economics

The study of the allocation and distribution of scare resources among competing wants.

Extrapolative statistical models

models that apply a formula to historical data and project results for a
future period. Such models include the simple linear trend model, the simple exponential model, and the
simple autoregressive model.

Factor model

A way of decomposing the factors that influence a security's rate of return into common and

Macroeconomics

The study of the determination of economic aggregates such as total output and the price level.

Market model

This relationship is sometimes called the single-index model. The market model says that the
return on a security depends on the return on the market portfolio and the extent of the security's
responsiveness as measured, by beta. In addition, the return will also depend on conditions that are unique to
the firm. Graphically, the market model can be depicted as a line fitted to a plot of asset returns against
returns on the market portfolio.

paradigm. See Efficient frontier.

representation.

A model of stock returns that decomposes influences on returns into a systematic factor,
as measured by the return on the broad market index, and firm specific factors.
