an informal relationship between a buyer and seller in which neither
party is obligated to adhere to specific terms for exchange. It occurs when the buyer
and seller of an input meet, exchange, and then go their separate ways. It is used when
inputs are “standardized”.
Spot exchange refers to informal relationship between buyer and seller.
When a buyer acquires inputs from a seller through an informal relationship, it is
called spot exchange.
In the presence of specialized investments, spot exchange does not insulate a buyer
Disadvantages of contracts are that they are unable to cover all contingencies and
costly to write.
Spot exchange is the optimal method for procuring a modest number of standardized
inputs that are sold by many firms in the marketplace.
Contract: a formal relationship between a buyer and seller that obligate the buyer and
seller to exchange at terms specified in a legal document.
Contracts reduce underinvestment and reduce costly opportunism.
It is optimal to acquire an input through a contract when the contracting environment
is simply and the cost of the contract is less than the transaction costs.
Contracts require costly, up-front expenditures.
Performance-based reward programs for firm managers are typically called incentive

Contract is the optimal method for procuring inputs that have well-defined and
measurable quality specifications and require highly specialized investments.
Vertical integration: a situation where a firm produces the inputs required to make its
When a firm produces its own inputs it engages in vertical integration.
Vertical integration mitigates transaction cost and reduces opportunism.
A firm manager should consider vertical integration if there are substantial specialized
investments and the inputs has characteristics that are hard to specify in a contract.
Producing inputs internally firms don’t rely on other firms for materials.
Spot exchange, contracts, and vertical integration are all methods of procuring inputs.
Transaction costs: costs associated with acquiring an input that are in excess of the
amount paid to the input supplier. Including: the cost of searching for a supplier
willing to sell a given input, the costs of negotiating a price at which the input will be
purchased. These costs may be in terms of the opportunity cost of time, legal fees, and
so forth, other investments and expenditures required to facilitate exchange.
Transaction costs incurred in the acquisition of an input that exceed the cost of the
input itself .
Specialized investment: an expenditure that must be made to allow two parties to
exchange but has little or no value in any alternative use.
Specialize investment increase transaction costs.
