How does this help us to answer the what, how & for
whom questions?
Markets prices = signals Serves to reward producers
for fulfilling our desires.
Forces consumers to conserve on the consumption of goods (and services, and resources . . .).
Adam SmithAdam Smith
“It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their
regard to their self interest.
We address ourselves, not to their humanity, but to their self-love, and
never talk to them of our necessities, but of their advantages.”
Prices … are a rationing device!
How else to ration? First come, first served? Brute force? Discrimination? Equal portions? [Marxist? NoNo!]
When a good is increasingly scarce, its price rises and we are forcedforced to reduce consumption.
Equally? Of course not!
ScenarioScenario: Kuwait falls into the Gulf.

In the long run, we expect that producers
will search for and find additional
supplies, Q and P.
What will be said of P=$5?
Markets don’t work! Prices are not fair! These prices are outrageous! This is an example of price gouging! This is an indictment against greedy
sellers!

1986 - $1.3 billion to slaughter dairy cows. No effect on milk, but on beef . . .
1991 - USDA buys butter at $1/lb. to sell abroad at 60 cents/lb.
1996 - Congress approves cartel in New England to raise milk prices 21%.
1999 - Milk price calculation simplified . . .
Began during G. D. of 1930s. 1981 - cheese giveaway. 1983 - $1 billion to “retire” 10,000 dairy
cows. No effect.
The Inefficiency of Price FloorsThe Inefficiency of Price Floors
Basic Formula Price (BFP) = last month's average price paid for manufacturing grade milk in Minnesota and Wisconsin+ [current grade AA butter price X 4.27 + current non-dry milk price X 8.07 - current dry-buttermilk price X 0.42] + [current cheddar cheese price X 9.87 + current grade A butter price X 0.238] - [last month's grade A butter price X 4.27 + last month's nondry-milk price X 8.07 + last month's dry-buttermilk price X 0.42] - [last month's cheddar cheese price X 9.87 + last month's grade A butter price X 0.238] + (present butter fat - 3.5) X [current month's butter price X 1.38] - [last month's price of manufacturing grade milk in Minnesota-Wisconsin X 0.028].

Lessons? Plenty of them . . .Lessons? Plenty of them . . . Cost to consumers of higher prices:
Butter = 2*ROW, Cheese = 1.5*ROW, Milk=1.26*ROW
Cost to taxpayers for dairy subsidies: 0 to $2.6 billion, depending on market conditions.
Health harm - more expensive for poor and elderly to get calcium.
No incentive to innovate in U.S. dairy industry (New Zealand milk is produced at about half our cost).
Since 1930, dairy farmers declined by 95%.
