Class #27 "Transaction Costs" (11/4/2011)

All models so far have assumed zero TRANSACTION COSTS, which are:
- Cost of arranging/negotiating/enforcing contracts and agreements. There are three categories.
                1. Physical Costs: Transportation, distance, (time?)
                2. Costs from Ignorance: Not being fully aware of all the opportunities available. 
                3. Interferance: from religious and cultural rules, laws, ect. 
- The best transaction cost reducers are the "Middle Men" (ex. grocery stores) They have the comparative advantage in reducing transaction costs.

What is it that solves the massive information problem in large, complex, impersonal, societies?
Prices: Signal of value and scarcity. Steers resources to where they are most valued. 

Prices emerge from markets, and produce order. There are three categories.
     1. $ prices (dollars)
     2. Non-$ prices, (time, health, ect.)
     3. prices which are a mix and have some $ price and some abstract price as well. 

In the marker there are two types of people:
Buyers = Demanders 
Sellers = Suppliers

Everyone(people, companies) are both buyers and sellers, whether it is for goods or for production factors.
