Yes, a monopolist can engage in price discrimination, which refers to the practice of charging different prices to different consumers for the same good or service, based on their willingness to pay. For price discrimination to be possible, a monopolist must be able to:
1. **Market Power**: The monopolist must have some degree of market power, allowing them to set prices above marginal cost.
2. **Segment the Market**: The monopolist must be able to identify different groups of consumers with varying price elasticities of demand and separate them. Effective market segmentation might depend on factors such as age, location, or purchase volume.
3. **Prevent Resale**: The monopolist must be able to prevent or restrict resale between consumers. If consumers can easily resell the product, it would undermine the monopolist's ability to charge different prices.
There are generally three degrees of price discrimination:
1. **First-Degree Price Discrimination (Perfect Price Discrimination)**: The monopolist charges each consumer the maximum price they're willing to pay. This maximizes the monopolist's profits but might lead to a loss of consumer surplus.
2. **Second-Degree Price Discrimination**: Prices vary according to the quantity consumed or the version of the product. An example is bulk discounts or different pricing for premium versions of a product.
3. **Third-Degree Price Discrimination**: Different prices are charged to different groups of consumers based on identifiable characteristics (e.g., student discounts, senior citizen discounts).
In summary, price discrimination is a common practice among monopolists, provided they can effectively segment the market and prevent resale.
