What is effective demand?

What is derived demand?
Demand for a factor of production that is used to produce another good or service.
What is joint demand?
Demand for a product that is directly and positively related to the market demand of a related product.
What is composite demand?
Some goods have more than one use; if market demand for one product from this good increases, the market supply of the other will fall as resources are reallocated.
What does quantity demanded represent?
It represents how many of an item a consumer will purchase at a specific price, affected by price factors.
What does the law of demand state?
Demand and price are inversely proportional.
What is the income effect in relation to demand?
If the price of a product decreases, consumers have more real purchasing power, so they buy more, increasing quantity demanded.
What is the substitution effect in relation to demand?
If the price of a product decreases, consumers are more likely to switch to it, increasing quantity demanded.
What is the law of diminishing marginal utility?
Marginal benefit falls as quantity consumed increases, so consumers are willing to pay less for each successive unit assuming a rational individual spends to maximise utility and the consumption of all other goods remains constant (CP)
What is utility?
The happiness or satisfaction derived by an individual from a given good or service.
What is total utility?
The satisfaction gained by a customer as a result of their overall consumption of a good.
What is marginal utility?
The change in satisfaction resulting from the consumption of the next unit of a good.
