Study Notes

Marginal Analysis for Optimization

Increasing Marginal Benefit (MB): Total Benefit (TB) increases with each additional unit but at a decreasing rate and this decrease implies an MWP/TB decreases.
Optimal Decision: To maximize total benefit minus total cost, purchase units where Marginal benefit is greater than marginal cost.
Example: The text provides an example, showcasing how an individual should maximize the amount of benefit they can gain, by consuming goods up to the point where marginal benefits equal marginal costs.
Demand Curve: A demand curve visually represents the relationship between quantity and price, effectively illustrating how many units consumers will purchase at different prices.

Consumer Choice Model

"Good": In economics, a good may be a physical item or an intangible product (like a service, a scientific breakthrough, a cooking recipe).
Contrast with "Bad": Pollution, for example, is considered a bad.
Willingness to Pay (WTP): An idea indicating the maximum a consumer is willing to contribute to gain more goods.
Total Willingness to Pay (TWP): The cumulative monetary value a consumer is happy to pay for the total quantity of goods sought.
Marginal Willingness to Pay (MWP): The value the consumer is willing to contribute/pay for one extra unit of goods.
Optimizing Behavior: Consumers seek to maximize their total benefits minus total costs (TWP - Total Costs) in their choices.
Marginal Benefit vs. Marginal Cost: The consumer makes additional purchases as long as the marginal benefit exceeds the price (marginal cost).

Marginal Analysis in Consumer Choice

Optimal Choice: Buying two units of a good is the optimal solution to the example's problem (the consumer will get the highest net benefit by consuming up to two units).
Demand Curve Construction: The Demand curve is derived from Marginal Willingness to Pay (MWP) schedule.
Net Benefit: Calculating the difference between the total willingness to pay(TWP) and total cost (TC), gives a measure of the consumer's well-being.

Additional Examples

Sunglasses Example: The example highlights how marginal analysis can predict consumer behavior using the principle of optimization. If the marginal benefit of buying a pair of sunglasses is higher than the marginal cost, (i.e, the price of the item), the consumer will purchase the item(s).
SodaClub Example: The case of a consumer purchasing membership in a club suggests that economists examine the net benefits when deciding upon membership. This can be expanded to any number of potential memberships.
