What is the reason for increasing opportunity costs? Why do the production frontiers of different nations have different shapes?
Why does a production frontier that is concave from the origin indicate increasing opportunity costs in both commodities? What does the slope of the production frontier measure? How does the slope
change as the nation produces more of the commodity measured along the horizontal axis? more of the commodity measured along the vertical axis?
Suppose you are a monopolist and find that the demand elasticity of your
product is different in two markets. What would be your pricing strategy?

terms of cloth?
(c) What is the range for mutually beneficial

Consider a Solow growth model with the
following production function:
Y-FiX.L) - K0.3 (AL) 0.7
(1) If A = 2, L= 20.000, and K = 400, what is output?
(2) Does this production function have constant
returns to scale? Explain.
(3) Suppose the labor force grows by 5% so that it is
now 21.000. By how
much does output increase?
(4) Starting again with the conditions in part (1),
what if capital increases by
5%, so that it is now 420. By how much does
output increase?

The market-friendly approach to development
emphasizes
(a) self-interested behavior of public officials in
LDCs.
(b) the dependence of LDCs on former colonial
powers.
(c) the inherent efficiency of markets in developing
countries.
(d) that markets in LDCs fail sometimes and non-
selective interventions can
promote economic development.
For an economy's output function »- {k)-VE
where y=(Y/L) and k = (K/L), which of the following
statements is correct?

capital is constant for all k.
(b) The output function is subject to constant returns
to scale.
(c) In this economy, labor and capital are not

(b) 38
(c) 40
(d) 47

accumulation.

productivity rises.
(d) developing countries save too much and invest
too little.

Dependency theory suggests that countries should become more inward-looking and less entangled with developed countries, trading only with
other developing countries. True/False

When the output stays the same after the use of each input has been doubled, then the economy’s production function follows a constant returns to scale. True/False
