Perfect substitutes have a linear utility function and a constant marginal rate of substitution, see figure 3. [7] If goods X and Y are perfect substitutes, any different consumption bundle will result in the consumer obtaining the same utility level for all the points on the indifference curve (utility function).

For two goods, fuel and new cars (consists of fuel consumption), are complements; that is, one is used with the other. In these cases the cross elasticity of demand will be negative, as shown by the decrease in demand for cars when the price for fuel will rise. In the case of perfect substitutes, the cross elasticity of demand is equal to ...
Pricing the base good at a relatively low price - this approach allows easy entry by consumers (e.g. low-price consumer printer vs. high-price cartridge) Pricing the base good at a relatively high price to the complementary good - this approach creates a barrier to entry and exit (e.g., a costly car vs inexpensive gas)
Price of related goods: The principal related goods are complements and substitutes. A complement is a good that is used with the primary good. Examples include hotdogs and mustard, beer and pretzels, automobiles and gasoline. (Perfect complements behave as a single good.) If the price of the complement goes up, the quantity demanded of the ...
The concept of the elasticity of substitution was developed by two different economists, each with their own focus. One of these economists was John Hicks, who defined elasticity of substitution as the change in percentage in the relative number of factors of production used, given a particular change in percentage in relative prices or marginal products.
U.S. gasoline prices rose earlier this month but are falling again after West Coast refinery outages subsided and seasonal demand fell. President Joe Biden plans to sell the last portion of a ...
On Wednesday, regular gasoline was going for an average of $3.83 across the country, according to auto club AAA, up five cents from last week and the first time prices have gone up in more than ...
Changes in the prices of related goods (substitutes and complements) Changes in disposable income, the magnitude of the shift also being related to the income elasticity of demand. Changes in tastes and preferences. Tastes and preferences are assumed to be fixed in the short-run. This assumption of fixed preferences is a necessary condition for ...
