ExampleExample
• Suppose two firms in an industry own their Suppose two firms in an industry own their land outrightland outright
• Firm A is located near a major railroad and can Firm A is located near a major railroad and can ship products for $10,000 a year less than ship products for $10,000 a year less than Firm B, which is 100 miles distant.Firm B, which is 100 miles distant.
• Economic Rent on the land is $10,000 per year Economic Rent on the land is $10,000 per year ($10,000 is what Firm B would be willing to ($10,000 is what Firm B would be willing to pay (OC) for the land less Firm A’s zero cost to pay (OC) for the land less Firm A’s zero cost to pay for its land this period—the rent goes to pay for its land this period—the rent goes to Firm A in lower costs)Firm A in lower costs)
• Thus, Firm A earns rent of $10,000 on its landThus, Firm A earns rent of $10,000 on its land

Why Markets for Assets May FailWhy Markets for Assets May Fail
• The source of the rent cannot be precisely The source of the rent cannot be precisely identified by external or sometimes even identified by external or sometimes even internal observersinternal observers
• Separating the assets from the context of the Separating the assets from the context of the firm renders them useless or significantly firm renders them useless or significantly impairs their usefulness or valueimpairs their usefulness or value
• The assets encounter Arrow’s Information The assets encounter Arrow’s Information (knowledge) Paradox: (knowledge) Paradox: – A potential buyer of information must know what the
information is in order to assess its worth. But once the buyer knows enough to assess its worth, he is in possession of the essentials, which he has acquired without cost.
• Therefore, the “assets” never go up for sale Therefore, the “assets” never go up for sale (OC is near 0), but they earn positive rents(OC is near 0), but they earn positive rents
