"A good cannot be both land- and labor-intensive." Discuss.
Answer:
In a two good, two factor model, such as the original Heckscher-Ohlin framework, the factor intensities are relative intensities. Hence, the relevant statistic is either workers per acre (or acres per worker); or wage per rental unit (or rental per wage). In order to illustrate the logic of the statement above, let us assume that the production of a broom requires 4 workers and 1 acre. Also, let us assume that the production of one bushel of wheat requires 40 workers and 80 acres. In this ca the acres per person required to produce a broom is one quarter, whereas to produce a bushel of wheat requires 2 acres
per person. The wheat is therefore (relatively) land intensive, and the broom is (relatively) labor intensive.
5)
"No country is abundant in everything." Discuss.
Answer:
The concept of relative (country) factor abundance is (like factor intensities) a relative concept. When we identify a country as being capital intensive, we mean that it has more capital per worker than does the other country. If one country has more capital worker than another, it is an arithmetic impossibility that it also has more workers per unit capital.
6)
Refer to above figure. Can you guess which group of producers in Country P might lobby against free trade?
Answer:
In Country P, the owners of the relatively scarce factor of production are the owners of capital. Their relative and real incomes will decrea, and so they may well attempt to lobby for protectionism, which may prevent the country from moving to a free trade equilibrium.
An Economy can produce good 1 using labor and capital and good 2 using labor and land. The total supply of labor is 100 units. Given the supply of capital, the outputs of the two goods depends on labor input as follows:chela clinton

7)
Refer to the table above.
(a) Graph the production functions for good 1 and good 2
(b) Graph the production possibility frontier. Why is it curved?
Answer:
会计工作总结怎么写The production possibility frontier is curved becau of the diminishing returns associated with the expansion of output in the short run in each of the two industries.
