any one know the definition of:

inelastic supply?
core concepts?
contestable?
timebased pricing?

Sure! I can explain the definitions of these terms to you:

1. Inelastic supply: In economics, inelastic supply refers to a situation where the quantity supplied of a good or service is not very responsive to changes in its price. When the supply is inelastic, producers are unable or unwilling to significantly increase or decrease the quantity supplied, even if the price changes. This can happen when there are limited or fixed resources, high production costs, or other factors that restrict the ability to adjust supply in response to changes in price.

2. Core concepts: "Core concepts" can refer to the fundamental ideas or principles that form the foundation of a particular field of study or subject. These concepts are considered essential for understanding the subject matter and are usually taught as the starting point for further learning. For example, in mathematics, core concepts might include numbers, operations, and basic algebraic principles. In science, core concepts could be atoms, molecules, and the laws of motion.

3. Contestable: In economics, the term "contestable" refers to a market or industry where there is potential for new firms to enter and compete with existing firms. A contestable market is characterized by low barriers to entry and exit, meaning that new businesses can easily enter the market if they believe they can be profitable. The concept of contestability suggests that even if there are only a few dominant firms in a market, competition can still be effective if the threat of new entrants is enough to constrain the behavior of existing firms.

4. Time-based pricing: Time-based pricing is a pricing strategy where the cost of a product or service is based on the time of consumption or usage. It involves varying the price according to different time periods, such as peak and off-peak hours. For example, electricity providers often use time-based pricing, with higher rates during peak demand hours and lower rates during off-peak periods. This strategy can incentivize consumers to shift their consumption to cheaper time periods, helping to balance demand and reduce strain on the system during peak times.

These explanations should give you a good understanding of the definitions. If you need more detailed information, feel free to ask!
