  2. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    For example, when demand is perfectly inelastic, by definition consumers have no alternative to purchasing the good or service if the price increases, so the quantity demanded would remain constant. Hence, suppliers can increase the price by the full amount of the tax, and the consumer would end up paying the entirety.

  3. Cross elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Cross_elasticity_of_demand

    Cross elasticity of demand of product B with respect to product A (η BA): = / / = > implies two goods are substitutes.Consumers purchase more B when the price of A increases. Example: the cross elasticity of demand of butter with respect to margarine is 0.81, so 1% increase in the price of margarine will increase the demand for butter by 0.81

    The butterfly diagram show a data-flow diagram connecting the inputs x (left) to the outputs y that depend on them (right) for a "butterfly" step of a radix-2 Cooley–Tukey FFT algorithm. This diagram resembles a butterfly as in the Morpho butterfly shown for comparison, hence the name. A commutative diagram depicting the five lemma

  5. Income elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Income_elasticity_of_demand

    It is measured as the ratio of the percentage change in quantity demanded to the percentage change in income. For example, if in response to a 10% increase in income, quantity demanded for a good or service were to increase by 20%, the income elasticity of demand would be 20%/10% = 2.0.

    The term was coined when variables began to be used for sets and mathematical structures. onto A function (which in mathematics is generally defined as mapping the elements of one set A to elements of another B) is called "A onto B" (instead of "A to B" or "A into B") only if it is surjective; it may even be said that "f is onto" (i. e ...

  7. Price elasticity of supply - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_supply

    Relatively inelastic supply: This is when the E s formula gives a result between zero and one, meaning that when there is a change in price, the percentage change in supply is lower than the percentage change in price. For example, if a product costs $1 and then increases to $1.10 the increase in price is 10% and therefore the change in supply ...

  8. Isoelastic function - Wikipedia

    en.wikipedia.org/wiki/Isoelastic_function

    An example in microeconomics is the constant elasticity demand function, in which p is the price of a product and D(p) is the resulting quantity demanded by consumers.For most goods the elasticity r (the responsiveness of quantity demanded to price) is negative, so it can be convenient to write the constant elasticity demand function with a negative sign on the exponent, in order for the ...

    In model theory, a branch of mathematical logic, the diagram of a structure is a simple but powerful concept for proving useful properties of a theory, ...
