Definition
Homo Economicus is a theoretical concept representing the idealized human as a rational and self-interested decision-maker. According to neoclassical economic theories, individuals possess complete rationality, have perfect access to information, and engage in consistent behaviors aimed at maximizing their utility or profit.

Examples
-
Example of Homo Economicus: A business owner meticulously calculates the optimal price for a product by analyzing market trends, customer preferences, and competitor pricing to maximize profits.
-
Example of Behavioral Economics: During a sale, customers might irrationally buy more products than they need simply because they perceive a limited-time discount, influenced by emotions rather than rational decision-making.
- Rational Choice Theory: The idea that individuals always make prudent and logical decisions, maximizing utility based on available information.
- Bounded Rationality: The concept that human decision-making is limited by cognitive deficits, available information, and time constraints, leading to satisficing rather than maximizing.
- Prospect Theory: Developed by Daniel Kahneman and Amos Tversky, it describes how people make decisions based on perceived gains and losses rather than final outcomes.

Frequently Asked Questions
Q: Is Homo Economicus a real person?
A: No, it’s not a figure you’d invite to a party! It’s a theoretical construct used for economic models.
Q: Why do economists consider Homo Economicus unrealistic?
A: Because humans are prone to emotions, biases, and irrational choices, making them less than perfect decision-makers.
Q: Can Homo Economicus ever live up to its ideals?
A: Only if there’s a personality upgrade and human emotions are placed on a permanent ‘Do Not Disturb’ mode! 🚫

- [ ] It's completely logical at all times.
- [x] It's influenced by emotions and cognitive biases.
- [ ] It can always be predicted.

- [x] Bounded rationality allows for human cognitive limitations.
- [ ] Bounded rationality only applies to low-income individuals.
- [ ] Bounded rationality is a mathematical model.
> **Explanation:** Bounded rationality acknowledges that humans operate within limited conditions, which affects decision-making unlike Homo Economicus.

- [ ] Rational Choice Theory
- [x] Prospect Theory
- [ ] Theory of Planned Behavior
- [ ] Homo Economicus Theory
> **Explanation:** Prospect Theory, proposed by Kahneman and Tversky, highlights how people evaluate potential losses and gains.
