Takeaways

• 😀 Human beings are known as homo economicus, meaning they are driven by the desire to fulfill their needs and maintain their lives through economic activities like buying and selling.
• 😀 In a transaction, demand, supply, and equilibrium prices influence one another.
• 😀 The price of goods, especially essentials, can increase before significant events like holidays due to a surge in demand, such as before Eid when the price of basic goods rises.
• 😀 Demand is the quantity of goods that consumers are willing to purchase at specific prices and times. Factors like price, income, taste, quality, and the availability of substitutes affect demand.
• 😀 As the price of a product increases, the demand typically decreases. On the other hand, lower prices generally lead to higher demand.
• 😀 The law of demand explains that as the price of a product goes down, the quantity demanded goes up, and vice versa. This relationship can be represented by a downward-sloping demand curve.
• 😀 Supply refers to the amount of goods that producers are willing to sell at specific prices and times, with factors like production costs, technology, expected profit, and non-economic factors influencing it.
• 😀 The law of supply states that when the price of a product increases, the quantity supplied also increases. Conversely, if the price falls, the quantity supplied decreases.
• 😀 Equilibrium price is the price at which the quantity demanded equals the quantity supplied. This is often the result of negotiations or bargaining in markets, like at traditional markets where buyers and sellers negotiate prices.
• 😀 The equilibrium price reflects the balance between demand and supply, where both parties, the buyer and seller, reach an agreement on the price, ensuring no excess demand or supply in the market.
