Show which of the following models can be estimated by the OLS, where X, y and Z are variables and α,β,γ are parameters to be estimated. The models can be rearranged if necessary.

(1) y_t=α+βx_t+u_t [5 marks]

(2) y_t=e^α x_t^β e^(u_t ) [5 marks]

(3) y_t=α+βγx_t+u_t [5 marks]

(4) y_t=α+βx_t Z_t+u_t [5 marks]

The following equations have been estimated by Ordinary Least Squares (OLS), where Y denotes annual earnings, P job evaluation points, and the subscripts m and f denote male and female respectively: Ym = 5000 + 100Pm Yf = 4000 + 80Pf Assume the average job evaluation score was 300 points in male-dominated jobs and 200 points in female-dominated jobs. What is the average pay in male-dominated jobs and in female-dominated jobs? Use a Oaxaca decomposition to determine the average pay...

For what kind of models can we use OLS?

Consider the following projects X and Y where the firm can choose only once. Project X costs $600 and has cash flows of $400 in each of the next two years. Project B also costs $ 600 and generates cash flows $500 and $275 for the next two years, respectively. Sketch a net present value profile (graphs) for each of these projects. For graphs you may use approximation Which project should the firm choose if the cost of capital is...

Consider the following projects, X and Y where the firm can only choose one. Project X costs $1500 and has cash flows of $678, $652, $347, $111, $54, $16 in each of the next 6 years. Project Y also costs $1500, and generates cash flows of $738, $693, $405 for the next 3 years, respectively. WACC=9.5%. A) Draw the timelines for both projects: X and Y. B) Calculate the projects’ NPVs, IRRs, payback periods. C) If the two projects are...

Dr Pepper’s preferences can be represented by the utility function u(x,y) = x + y where x is his consumption of Coca Cola (hereafter, referred to as Coke) and y is his consumption of orange juice (hereafter, referred to as OJ). Initially, both types of drinks are not taxed and with an income of $12 he faces prices ($1, $2). On the advice of nutritionists, the government decides to impose a specific tax of $2 on Coke which leads to...

Car Phones, Inc., sells two models of car telephones: model X and model Y. Records show that 3 hours of sales time are used for each model X telephone that is sold and 5 hours of sales time for each model Y telephone. A total of 600 hours of sales time is available for the next 4 week period. In addition, management planning policies call for minimum sales goals of 25 units for both model X and model Y. The...
