  1. Kent sells lemonade in a competitive market on a busy street corner. His production function is F(L, K) = L1/3 K1/3 where output q is gallons of lemonade, K is the pounds of lemons he uses and L is the number of labour-hours spent squeezing them. The corresponding marginal products are MPL= 13L-23K13 and MPK= 13L13K-23. Every pound of lemons cost r and the wage rate of lemon squeezers is w.
    1. Prove that this production process has decreasing returns to scale.
    2. On a graph with hours of lemon-squeezing (L) on the horizontal axis and pounds of lemons (K) on the vertical axis, illustrate an isoquant that represents a particular production level q. What is the equation of the isoquant?
    3. What is the equation for a slope of an isoquant? Is it constant? What does the slope indicate? Explain.
    4. What are the conditions that identify the cost minimizing bundle for any output? Illustrate on a clearly labelled diagram.
    5. Set up the cost minimization problem and solve for the conditional input demands as functions of the exogenous variables.
    6. Derive the cost function (as a function of only the exogenous variables).
    7. Continue with total cost function derived in previous part and derive the average cost. Is it upward or downward sloping? Explain.

Earnie sells lemonade at a busy street corner in Rollaville. His production function is f(x,y) = x^1/4*y^1/2 where output is measured in gallons, x is the number of pounds of lemons he uses, and y is the number of labor-hours spent squeezing them. The price of a pound of lemons is $1 and the wage rate for the lemon-squeezer (Earnie’s best friend, Bert) is also $1. While Earnie can hire Bert for any amount of time, he has only three...
