Suppose a fossil fuel has stable demand and a constant marginal cost. There are only two periods. MB = 8 – 0.4q; and MC = 2. Suppose there are only 20 units of the resource and the discount rate is r = 0.10. Solve for the dynamic optimum across periods. Show your mathematical solution, but also depict it graphically (ACCURACY COUNTS) using the double-vertical axes model from class. %3D %3D

Styles 6. The following two regression models are Probit and Logit respectively: Pr(Y=1|X)=(Bo+Bi xXr+Bzx X2) Pr(Y=1|X)=F(Bu + B₁ × Xs + B₂ × X2) (a) what functions do and F represent? (b) How do Probit, and Logit ensure that the predicted probabilities are always between 0 and 1? (c) Sketch a graph of the Y= $(Z) function. (Z on the horizontal axis, Y on the vertical axis) (d) What estimation method is used to estimate the coefficients in a Probit/Logit model? (e) What are the two measures of fit for models with binary dependent variables? Focus 88 B E

The revenue from the sale of a product is, in dollars, R = 1500x + 3000(2x+3)-1 - 1000 where x is the number of units sold. Find the marginal revenue when 200 units are sold. (Round your answer to two decimal places.) $ Interpret your result. If the sales go from 200 units sold to units sold, the revenue will increase by about $ Suppose that the weekly sales volume y (in thousands of units sold) depends on the price per unit (in dollars) of the product according to the following formula. y = 30(3p+ 1) −2/5, p > 0 (a) What is the rate of change in sales volume when the price is $24? (Round your answer to three decimal places.) dy = dp (b) Interpret your answer to part (a). (Round your answer to the nearest whole number.) If the price increases $1, the sales volume will decrease by If the demand for q units of a product priced at $p per unit is described by the equation p = 500 √29 + 7 find the rate of change of p with respect to q. dp = dq 1 units.

Consider the following Cobb-Douglas production function for the bus transportation system in a city:  Q = Lβ1Fβ2Bβ3 Where  L = labour input in worker hours              F = fuel input in gallons              B = capital input in number of buses              Q = output measured in millions of bus miles   Suppose that the parameters (α, β1, β2 and β3) of this model were estimated using annual data for the past 25 years. The following results were obtained: β1 = 0.45, β2 = 0.20 and β3 = 0.30 a.         Determine the (i) labour, (ii) fuel, and (iii) capital-input production elasticities
