1. Consider a firm with the following production function: Q = KL^1/2

(a) Consider an output level of Q = 100. Find the expression of the isoquant for this output level.

(b) Find the marginal product of labor, MPL. Is it increasing, decreasing, or constant in the units of labor, L, that the firm uses?

(c) Find the marginal product of capital, MPK. Is it increasing, decreasing, or constant in the units of capital, K, that the firm uses?

(d) Use your result in parts (b)-(c) to find the marginal rate of technical substitution, MRTS, for this firm.

(e) Is the MRTS increasing or decreasing in the units of labor, L? What does that imply about the shape of the isoquant?

(f) Given your result in part (d), what can you say about the firm’s ability to substitute one input for another? (g) Assume now that the firm were to increase all inputs by a common factor > 0. What happens to the output that the firm produces? [Hint: check whether the firm’s production function exhibits increasing, decreasing, or constant returns to scale.]

For the money demand function, we assumed that money demand depends on income and interest rate. Consider an economy where money demand does not depend on income and is only a function of interest rate.

M^d = L(i)

Suppose that the economy is open and on a flexible exchange rate:

(a) Draw the money demand and supply curves with money demand and supply on x-axis and interest rate on y-axis.

(b) Show what happens to money demand and supply curves if income changes.

(c) Derive the LM curve.

(d) Derive the AD curve.

Policy Enforcement: The text states that stiff penalties (sanctions) for environmental violators can be much more complicated than the simple economic model suggests (which simply assumes: Higher the penalty, greater the deterrence!).     Explain.

Question

Tesco is a global grocery and general merchandise retailer headquartered in Cheshunt, United Kingdom. It is the third-largest retailer in the world measured by revenues (after Wal-Mart and Carrefour) and the second-largest measured by profits Tesco House, head office in Cheshunt, Hertfordshire. (after Wal-Mart). It has stores in 14 countries across Asia, Europe and North America and is the grocery market leader in the UK (where it has a market share of around 30%), Malaysia, the Republic of Ireland and Thailand. Tesco opened its first store in Malaysia in May 2002 with the opening of its first hypermarket in Puchong, Selangor. Tesco Malaysia currently operates 49 Tesco and Tesco Extra stores.

1. Define the current strategic problems and opportunities faced by TESCO in Malaysia or in selected branches in Malaysia.

2. Analyze TESCO’s marketing and innovation strategy transformation designed to position the company on the cutting edge of consumer trends.

3. Evaluate TESCO’s strategy of developing healthy lifestyle or go green concept in Malaysia.

4. Compare and contrast the performance of TESCO with the nearest competitor of a kind in Malaysia.

5. Provide recommendations to management of TESCO on ways to improve strategically in Malaysia.

Tomato yields

Number of plants 3 4 5 6 7 8 Pounds of tomatoes 42 54 65 75 84 92

Chris runs a CSA (“community sponsored agriculture”) farm, and they are trying to determine the optimal amount of “investment” in tomato seedlings. The table above shows the plot’s (expected) yield as a function of the number of tomato plants.

1. (a) Tabulate the MPK, in terms of pounds of tomatoes, as a function of the number of tomato plants.

2. (b) Assumetheinterestrateis7%(r=0.07),thepriceofaseedlingis$1,andtomatoessellfor$0.10/pound.

   Tomato plants are annuals (they live only one year) so d = 1. Calculate the user cost.

3. (c) Find the optimal amount of investment (the number of seedlings to plant).

4. (d) Repeat the calculation with:

   1. (i) A 5 percentage point increase in the interest rate, to 12%.

   2. (ii) A drop on the price of tomatoes, to $0.09/pound (r = 7%).

   3. (iii) A drop in the price of seedlings, to $0.90 (r = 7% and tomato price = $0.10).

   4. (iv) The introduction of a new variety of tomatoes with a 10% higher yield, regardless of the number

      planted (r = 7%, tomato price = $0.10 and seedling price = $1).
