Let d d be the usual metric on LaTeX: \mathbb{R}^2 R 2 and let \rho ρ be the square metric on LaTeX: \mathbb{R}^2 R 2 , that is, LaTeX: d(x,y)=(|x_1-y_1|^2+|x_2-y_2|^2)^{1/2} d ( x , y ) = ( | x 1 − y 1 | 2 + | x 2 − y 2 | 2 ) 1 / 2 , and LaTeX: \rho(x,y)=\max\{|x_1-y_1|,|x_2-y_2|\} ρ ( x , y ) = max { | x 1 − y 1 | , | x 2 − y 2 | } , where LaTeX: x=(x_1,x_2) x = ( x 1 , x 2 ) , LaTeX: y=(y_1,y_2) y = ( y 1 , y 2 ) . Without directly referring to any theorem from Section 1.5, prove explicitly that (a) LaTeX: \rho(x,y)\leq d(x,y)\leq \sqrt{2}\rho(x,y) ρ ( x , y ) ≤ d ( x , y ) ≤ 2 ρ ( x , y ) (10 points) (b) d d and \rho ρ generate the same topology on LaTeX: \mathbb{R}^2 R 2 .

d. Based on the information about the corporate bond provided in part b, calculate yields and then construct a new yield curve graph that shows both the Treasury and the corporate bonds.

b.Suppose you are considering two possible investment opportunities: a 12-year Trea- sury bond and a 7-year, A-rated corporate bond. The current real risk-free rate is 4%; and inflation is expected to be 2% for the next 2 years, 3% for the following 4 years, and 4% thereafter. The maturity risk premium is estimated by this formula: MRP 1⁄4 0.1 (t – 1)%. The liquidity premium for the corporate bond is estimated to be 0.7%. Finally,you may determine the default risk premium, given the company’s bond rating, from the default risk premium table in the text. What yield would you predict for each of these two investments?
