All You Can Eat? When individuals put effort into something, most are reluctant to back out even if staying on the same course leads more loss. Biases Affecting Logic Familiarity: The Downward Slope of the Demand Curve: One party of five ate 18 pounds of crab, another had 30 refills of crab legs.
Loss Aversion and Framing: Tastes and preferences are given, and play a large role in decision making. Behavioral economics attempts to catalogue the biases that result from bounded rationality. Shifts of Demand When the price of one Prentice14e ppt ch20 3 falls while everything else is constant, two things occur: Consumer Choice Each consumer allocates a specific budget to expenditure, and then allocates the expenditure to maximize utility.
The consumer must reallocate income across goods. For each change, a new demand curve is derived. Shifts of Demand, Continued The individual demand curve is defined by income, tastes and preferences, the price of the good, and the price of related goods.
But for too many Red Lobster customers, devouring piles of crab became a contest. Other goods become relatively more expensive, so consumers buy more of the less expensive good and less of the more expensive goods.
If two goods offer the same marginal utility, the consumer will be indifferent between the two. With income fixed, if the price of one good rises, the consumer is able to buy fewer goods and services, causing demand to fall.
Behavioral Economics Bounded rationality admits that complete and perfect information is unlikely and that people make decisions that may seem irrational, but in reality are the rational results of a brain that is economizing.
The consumer can buy more total goods with the same income. This is also referred to as the consumer equilibrium. Diminishing Marginal Utility Utility diminishes over time—the shorter the time period, the more quickly marginal utility diminishes.
This is called the substitution effect. Biases Affecting Logic Overconfidence: Marginal Utility Marginal utility: Utility is a measure of the satisfaction received from possessing or consuming goods and services.
Consumers make choices that give them the greatest utility—they maximize utility. The emotional part is the limibiclimbic system especially the amygdala. The market demand curve is the sum of all the individual demand curves.
Demand Curve for Used CDs: The logical part is the pre frontal cortex.
Neuroeconomics Some economists have joined forces with biologists and neurologists to attempt to see how the brain handles economic decisions.
Consumer Equilibrium Equimarginal principle: Principle of diminishing marginal utility: Total and Marginal Utility: The Downward Slope of the Demand Curve The inverse relation between price and quantity demanded arises from diminishing marginal utility and consumer equilibrium.
Shifts of Demand, Continued: MRI scans have revealed the two parts of the brain in which most decisions take place. Decision Making People compare the perceived costs and benefits of alternatives and select those that they believe give them the greatest relative benefits.
The number of consumers also affects the market demand curve. This is called the income effect. Consumers are not identical—the rate at which marginal utility diminishes depends on individual tastes and preferences, and so differs across consumers.
