Step 1: Understand the concept of excludability. A good is excludable if it is possible to prevent people who do not pay for it from consuming it.
Step 2: Recall the four types of goods classified by excludability and rivalry: private goods, club goods, common resources, and public goods.
Step 3: Identify which goods are excludable. Private goods are excludable because owners can prevent non-payers from using them. Club goods are also excludable because access can be restricted to paying members.
Step 4: Recognize that common resources and public goods are non-excludable. Common resources are rivalrous but non-excludable, while public goods are both non-rivalrous and non-excludable.
Step 5: Conclude that the goods that are excludable include private goods and club goods, as these are the types where exclusion from consumption is possible.
