Give an example of a firm using a two-part tariff as part of its pricing strategy.

When it comes to selling products or services, businesses have a variety of pricing strategies at their disposal. One sophisticated approach is the two-part tariff, where costs to the consumer are split into two distinct categories: a fixed fee and a variable charge based on usage. This strategy is particularly effective in segments where the provider wants to cover fixed costs upfront and also benefit from the customer's level of engagement with the service.

The two-part tariff allows firms to maximize profits by extracting consumer surplus. Consumer surplus is the difference between what consumers are willing to pay and what they actually pay. By charging a fixed fee, businesses are able to capture a portion of this surplus up front. Then, with the per-unit charge, they can align the price more closely with the actual consumption, ensuring that those who use the service more, pay more. This can lead to increased revenue without deterring low-usage customers, who might be put off by high usage rates alone.

The lump-sum fee is the part of the two-part tariff that customers pay regardless of the quantity they consume. It's a fixed charge that covers the basic access to a product or service. Think of it like an entry fee that grants you the right to participate. This fee is particularly important for businesses as it guarantees a stream of revenue independent of usage, helping to cover fixed costs such as rent, utilities, or maintenance.

For instance, a one-time joining fee for a membership program not only filters in committed customers but also provides the company with upfront capital, which can be particularly valuable for cash flow management. Bear in mind that the lump-sum fee needs to be set at a level that does not deter too many customers, while still capturing value. Companies often carefully calibrate this fee based on customer willingness to pay, which can be gleaned from market research or historical data.

In contrast to the lump-sum fee, the per-unit charge in a two-part tariff is the cost associated with the actual consumption of goods or services. This variable component ensures that customers who use more, pay more, aligning their costs directly with their level of consumption.

For example, a gym may charge a per-class fee for special workout sessions, meaning that regular class attendees will incur additional costs proportional to their usage. This approach incentivizes efficient usage and allows companies to profit from high-demand services. In setting per-unit charges, businesses must consider the marginal cost of providing the service, the competitive landscape, and consumer price sensitivity. The key is to find a balance that encourages usage without discouraging it due to high incremental costs, or losing potential profits by setting the per-unit price too low.
