用总需求一总供给模型说明，经济中由于总需求不足引起的小于充分就业的均衡这种情况下如何

Henry was a carpenter of our village. Once I asked him to make a table for my family. A week later, Henry sent us the table and the bill as well.

My wife said to me, "It's a beautiful table, dear, isn't it?"

"I won't decide about that until I see the bill." I said.

Henry was drinking a glass of water. He laughed and gave me a piece of paper. It said,

Bill

One dining table                 June 10, 2011

Cost of wood                       17.00

Paint                               1.50

Work, 8 hours (1 an hour)             8.00

Total(总计)                         36.50

When I was looking at the bill, Henry said," It's a fine day, isn't it? Quite sunny."

"Yes," I said. "I'm glad it is only the 10th of June."

"Me too, " said Henry." You wait. It will be a bit hotter by the end of the month."

"Yes, hotter and more expensive. The table will be 20 more expensive on June 30th, won't they, Henry? " I said, "If it isn't too much trouble, please add it up again. You can forget the date."

"OK, man. You are such a guy." Henry said with a smile in his two blue eyes, and he left with the money he should get.
