function. • The production function for good X gives the maximum quantities of good X that a firm can produce with various amounts of factor inputs.
– For instance, the production function for manufactures (food) tells us the quantity of manufactures (food) that can be produced given any input of labor and capital (land).

– The economy’s output of manufactures depends on how much capital and labor are used in that sector.
• This relationship is summarized by a production

The Specific Factors Model
• The production function for manufactures is given by
QM = QM (K, LM)
where: – QM is the economy’s output of manufactures – K is the economy’s capital stock – LM is the labor force employed in manufactures

• The production function for food is given by
QF = QF (T, LF)
where: – QF is the economy’s output of food – T is the economy’s supply of land – LF is the labor force employed in food
income distribution.

The Specific Factors Model
Assumptions of the Model
• • • • Assume that we are dealing with one economy that can produce
two goods, manufactures and food. There are three factors of production; labor (L), capital (K) and land (T for terrain). Manufactures are produced using capital and labor (but not land). Food is produced using land and labor (but not capital). – Labor is therefore a mobile factor that can be used in either sector. – Land and capital are both specific factors that can be used only in the production of one good.

• Perfect Competition prevails in all markets.
The Specific Factors Model
• How much of each good does the economy produce?
• Resources cannot move immediately or costlessly
from one industry to another. • Industries differ in the factors of production they demand.
The specific factors model allows trade to affect
