Normal Goods:
* Definition: A good for which demand increases as consumer income increases. In other words, as people become wealthier, they tend to buy more of these goods.
* Examples: Cars, electronics, restaurant meals, vacations.
Normal Demand Curve:
* Definition: A demand curve that slopes downwards from left to right, indicating that as the price of a good decreases, the quantity demanded increases (and vice versa). This relationship is generally true for most goods.
* Explanation: This is based on the law of demand, which states that, all else being equal, the lower the price of a good, the greater the quantity demanded.
Important Note: There are exceptions to the concept of normal goods. These are known as inferior goods, where demand decreases as income rises. An example could be generic, cheaper brands of food products.
In Summary:
* Normal goods are goods where demand rises with income.
* Normal demand curve describes the typical relationship between price and quantity demanded, where lower prices lead to higher demand.
