A hidden cost is a cost imposed by a transaction or activity that is not immediately apparent simply by looking at the trade occurring.
Further information: Transaction cost
These are the costs involved in making the transaction. They may include:
- Search costs: Costs incurred by parties in trying to find each other.
- Enforcement costs: Costs incurred by parties in ensuring that any agreement they make is enforced.
- Taxes and other costs of complying with the law.
Further information: Opportunity cost
The opportunity cost of a resource is the net benefit that would have accrued from its second best use.
Costs of intangibles
Intangibles may include time, human experience, trust that parties have in each other, etc.
Further information: External cost
External costs are costs imposed on parties who are not involved in the transaction, and thus have no direct control over whether it occurs.
Further information: Psychic cost
Psychic costs are costs imposed in the form of stress on the parties involved. When these costs are internal, they may be treated as transaction costs, and they can be factored in by the parties into their reservation prices if they can factor in the costs in advance. There may also be external psychic costs, which may be direct or indirect.
