Sure, here are some more economic terms and examples:

1. Price discrimination: When a firm charges different prices to different customers for the same product or service based on their willingness to pay. For example, airlines often charge different fares for the same seat depending on factors like the time of day, day of the week, and how far in advance the ticket was purchased.

2. Opportunity cost: The cost of choosing one option over another, which is the value of the best alternative that was not chosen. For example, if you choose to spend money on a new phone, the opportunity cost is the other things you could have purchased with that money instead, like a new laptop or a vacation.

3. Monopoly: When a single firm dominates a market and has the power to set prices and control supply. For example, the electricity provider in a small town may be a monopoly because there are no other providers, giving them the power to charge higher prices and provide poor quality service without fear of competition.

4. Elasticity: The responsiveness of demand or supply to changes in price or other factors. For example, if the price of a luxury car increases, the demand for it may decrease more than the demand for a necessity like gasoline, which has a lower elasticity of demand.

5. Gini coefficient: A measure of income inequality in a society, ranging from 0 (perfect equality) to 1 (perfect inequality). For example, if the Gini coefficient of a country is 0.4, it means that there is a significant gap between the incomes of the richest and poorest members of society.

6. Public goods: Goods or services that are non-excludable (once produced, they cannot be easily withheld from non-payers) and non-rival (consumption by one person does not diminish the consumption by another). Examples of public goods include national defense, street lighting, and clean air.

7. Deadweight loss: The loss of economic efficiency that occurs when the equilibrium quantity of a good or service is not produced or consumed due to market inefficiencies. For example, if a tax on a product is so high that it causes producers to stop producing the good, the resulting deadweight loss would be the value of the goods that were not produced.

I hope these examples and explanations help you understand these economic concepts better!
