To determine

The appropriate principle of individual choice used.

Concept Introduction:

Principles of Individual Choice:

  • “Choice is necessary because resources are scarce”- Resources are always scarce in respect to its use, a single resource can be put to various alternative uses. Therefore, one has to choose between the various uses.
  • “The true cost of something is its opportunity cost”- The value of any commodity is derived from the forgone cost to get that particular commodity.
  • “How much is the decision at the margin”- The choice of having something depends on the benefits one receive from that choice.
  • “People usually exploit opportunities to make them better off”- People are always fond of alternative incentive, which can make them in better situation as compared to the previous situation.
  • Gains from trade”- Individual always gain from trade by selling the product in which they are specialized and purchasing the product in which they are comparatively less specialized.
  • “Market moves towards equilibrium”- Market always tries to settle down at a point where no individual is comparatively better off in changing his choice.
  • “Resources should be used efficiently to achieve society’s goals”- Resources should be used in such a way that will not make any better off by making the other individual worse off.
  • “Markets usually lead to efficiency”- People always look for the opportunity, which can make them better off without making any other person worse off, this leads to efficiency in the market.
  • “When markets don’t achieve efficiency, government intervention can improve society’s welfare”- Government intervention is required when the market do not correct itself.
  • “One person’s spending is another person’s income”- The economy will always go on because a person earns only when the other person spends.
  • “Overall spending sometimes gets out of line with the economy’s productive capacity”- The economy can face inflation at the time when spending of whole economy raises all together.
  • “Government policies can change spending”- Various fiscal and monetary policies of government are used to correct the situation of the economy and adjust the spending.

Consider an economy that exhibits both population growth (L grows at rate n) and technological progress (A grows at rate a) described by the production function, Y = F(K, AL) = Ka (AL)¹-α Here K is capital and Y is output. (a) Show that this production function exhibits constant returns to scale. [2 marks] (b) What is the per-effective-worker production function, y = f(k), (where y = Y/AL k K/AL)? (Show your working.) [2 marks] (c) Find expressions for the steady-state capital-output ratio, capital stock per effective worker, and output per effective worker, as a function of the saving rate (s), the depreciation rate (8), the population growth rate (n), the rate of technological progress (a), and the coefficient a. (You may assume the condition that capital per effective worker evolves according to Ak = sf (k) - (a+n+8)k.) [5 marks] (d) Show that at the Golden Rule steady state the saving rate for this economy is equal to the parameter a. [6 marks]
A firm faces the following production function, Y = AKα L¹-a (1) Here Y is output, K is capital, L is fixed labour, and A is a measure of technology. The firm uses an optimal amount of capital determined by the condition, MPK = r +8 (2) Where MPK is the marginal productivity of capital, r is the real interest rate, and ♪ is the depreciation rate. (a) Using equations (1) and (2) find an expression for K*, the optimal amount of capital the firm should use. [3 marks] (b) Referring to your result from part (a), comment on what happens to K* when each of the following variables change (holding other variables constant), (i) The measure of technology (A) falls (ii) The depreciation rate (8) increases (iii) The real interest rate (r) increases [2 marks] [2 marks] [2 marks] [Hint: For each of parts (i)-(iii) you are being asked to comment on what happens to K* if just the variable mentioned in the question part changes. Your answer should state whether K* increases, decreases, or stays the…
In the week-4 materials, when deriving labour supply, we assumed that the substitution effect dominated the income effect. What impact would there be on labour supply if this was not the case? Briefly investigate how such a change could theoretically affect the imposition of a minimum wage above the market clearing wage. (Your answer is likely to benefit from diagrammatic support.)
