Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...
This page compares the properties of several typical utility functions of divisible goods. These functions are commonly used as examples in consumer theory . The functions are ordinal utility functions, which means that their properties are invariant under positive monotone transformation .
To test divisibility by any number expressed as the product of prime factors , we can separately test for divisibility by each prime to its appropriate power. For example, testing divisibility by 24 (24 = 8 × 3 = 2 3 × 3) is equivalent to testing divisibility by 8 (2 3 ) and 3 simultaneously, thus we need only show divisibility by 8 and by 3 ...
The consumer has ranked all available alternative combinations of commodities in terms of the satisfaction they provide him. Assume that there are two consumption bundles A and B each containing two commodities x and y. A consumer can unambiguously determine that one and only one of the following is the case:
Wild fish stocks are a rivalrous good, as the amount of fish caught by one boat reduces the number of fish available to be caught by others. In economics, a good is said to be rivalrous or a rival if its consumption by one consumer prevents simultaneous consumption by other consumers, [1] or if consumption by one party reduces the ability of another party to consume it.
Consumer math comprises practical mathematical techniques used in commerce and everyday life. In the United States, consumer math is typically offered in high schools , some elementary schools , or in some colleges which grant associate's degrees .
Infinite divisibility arises in different ways in philosophy, physics, economics, order theory (a branch of mathematics), and probability theory (also a branch of mathematics). One may speak of infinite divisibility, or the lack thereof, of matter , space , time , money , or abstract mathematical objects such as the continuum .
Normal goods are goods that experience an increase in demand as the income of consumers increases. The demand function of a normal good is downward sloping, which means there is an inverse relationship between the price and quantity demanded. [8] In other words, price elasticity of demand is negative for normal goods. Common goods mean that ...
