Market Exchange With Production

The table below shows the quantities of product X that a producer can produce in one growing season on a 1 acre farm using different amounts of labor. The dollar values assume that the land rents for \$100 and labor's wage is \$300 per growing season.

Land Labor Total Output Marginal Product Total Variable Cost Total Cost Marginal Cost Average Variable Cost Average Total Cost
1 0 0 0 100
1 1 6 6 300 400 50.00 50.00 66.67
1 2 13 7 600 700 42.86 46.15 53.85
1 3 21 8 900 1000 37.50 42.86 47.62
1 4 30 9 1200 1300 33.33 40.00 43.33
1 5 38 8 1500 1600 37.50 39.47 42.11
1 6 45 7 1800 1900 42.86 40.00 42.22
1 7 51 6 2100 2200 50.00 41.18 43.14
1 8 56 5 2400 2500 60.00 42.86 44.64
1 9 60 4 2700 2800 75.00 45.00 46.67
1 10 63 3 3000 3100 100.00 47.62 49.21
1 11 65 2 3300 3400 150.00 50.77 52.31

This next table is a marginal value table for one individual for product X. MV is measured in dollars. Use these two tables to answer the last question.

Quantity of X per growing season Marginal Value
1 150
2 137
3 100
4 92
5 84
6 75
7 60
8 50
9 43
10 37

Suppose that there is a market for X that consists of 10 identical producers, each with the same production costs as shown in the table above. In this market there are also 100 consumers, each with the marginal value as shown in the mv table above. Assume that all transaction costs are zero and traders will trade when indifferent:
a. What will be the equilibrium price for product X?
b. How many units of X will each producer produce?
c. How much profit will each producer earn?
d. How many workers will each producer employ?
e. If the government thought that the price you determined in 5a was "unfair" and passed a law saying the price could not be greater than \$43,
would there be a shortage or a surplus in this market?

#### Solution Preview

Let us start with the consumer. A consumer will purchase X only if MV > P. Let's say we are looking for the position at which MV = P.

Quantity of X per growing season Marginal Value
1 150
2 137
3 100
4 92
5 84
6 75
7 60
8 50
9 43
10 37

You can calculate the demand in the following manner. If, using the table above, the price is less than each unit MV for each person, you can assume that they will buy it. So, if the price is ...

## Mychorrhizal Fungi

Cooperation and trade are common in the natural world. Based on the cost of production and the constraints presented by the environment, an organism may be more successful by trading for a product than producing it. In this situation the organism may specialize in one product and trade for another. In this assignment we will examine an example of trading partners, mycorrhizal fungi and plants, and compare it to the principles of international trade, an important component of macroeconomics. After you view this tutorial, consider some of the principles it introduced and how they apply to specialization and trade between the symbiotic partners that make up a mycorrhizal association.

Scientists believe that this symbiosis may have been key to plants' success on land. Begin your introduction to this symbiosis at the Compost Gardener, and be sure to view their video. Next, proceed to this site maintained by the University of Western Australia, School of Plant Biology: http://mycorrhizas.info/vam.html to complete your research and locate important images for your assignment.
