Limitations Of The Model Of Indifference Curves
➡️ Income effect: When the price of a normal good decreases, the consumer's purchasing power increases, leading to an increase in demand. For an inferior good, the opposite is true; when the price decreases, the consumer's purchasing power decreases, leading to a decrease in demand. For a Giffen good, the demand increases when the price increases.
➡️ Substitution effect: When the price of a normal good decreases, it becomes relatively cheaper compared to other goods, leading to an increase in demand. For an inferior good, the opposite is true; when the price decreases, it becomes relatively more expensive compared to other goods, leading to a decrease in demand. For a Giffen good, the demand increases when the price increases.
➡️ Price effect: The price effect is the difference between the income and substitution effects. For a normal good, the price effect is positive; when the price decreases, the demand increases. For an inferior good, the price effect is negative; when the price decreases, the demand decreases. For a Giffen good, the price effect is positive; when the price increases, the demand increases.
What are the main limitations of the model of indifference curves in economics?
The model of indifference curves assumes that consumers have perfect information, rational preferences, and consistent behavior. However, in reality, consumers may have limited information, bounded rationality, and inconsistent preferences. Moreover, the model does not account for external factors such as social norms, peer pressure, and advertising that may influence consumer behavior.
How does the model of indifference curves fail to capture the complexity of consumer choice?
The model of indifference curves assumes that consumers make choices based solely on their preferences for goods and services. However, in reality, consumers may also consider other factors such as income, prices, availability, and quality of goods and services. Moreover, the model does not account for the fact that consumers may have multiple goals and constraints that affect their decision-making process.
Can the limitations of the model of indifference curves be overcome?
While the limitations of the model of indifference curves cannot be completely overcome, economists have developed alternative models that address some of these limitations. For example, the model of bounded rationality recognizes that consumers may have limited cognitive abilities and information processing capacity. The model of behavioral economics incorporates insights from psychology and sociology to explain how social and cognitive factors influence consumer behavior.
