Indifference map with two budget lines (red) depending on the price of Giffen good x. In microeconomics and consumer theory, a Giffen good is a product that people consume more of as the price rises and vice versa, violating the law of demand.
In economics, a complementary good is a good whose appeal increases with the popularity of its complement. [ further explanation needed ] Technically, it displays a negative cross elasticity of demand and that demand for it increases when the price of another good decreases. [ 1 ]
In economics and game theory, the decisions of two or more players are called strategic complements if they mutually reinforce one another, and they are called strategic substitutes if they mutually offset one another. These terms were originally coined by Bulow, Geanakoplos, and Klemperer (1985).
Only if the two products satisfy the three conditions, will they be classified as close substitutes according to economic theory. The opposite of a substitute good is a complementary good, these are goods that are dependent on another. An example of complementary goods are cereal and milk. An example of substitute goods are tea and coffee.
Example: the cross elasticity of demand of entertainment with respect to food is −0.72, so 1% increase in the price of food will decrease the demand for entertainment by 0.72%. η B A = 0 {\displaystyle \eta _{BA}=0} implies two goods are independent (a price change of good A is unrelated to demand change of good B), so changes in the price ...
The theory is generally associated with Hirschman. He presented a complete theoretical formulation of the strategy. Underdeveloped countries display common characteristics: low levels of GNI per capita and slow GNI per capita growth, large income inequalities and widespread poverty, low levels of productivity, great dependence on agriculture, a backward industrial structure, a high proportion ...
The main goal of the new model is to re-frame economic problems and set new goals. In this context, the model is also referred to as a "wake-up call to transform our capitalist worldview". [5] In this model, an economy is considered prosperous when all twelve social foundations are met without overshooting any of the nine ecological ceilings ...
The goal is to find models in which existence of money can alter the equilibrium solutions, perhaps because the initial position of agents depends on monetary prices. Some critics of general equilibrium modeling contend that much research in these models constitutes exercises in pure mathematics with no connection to actual economies.
