Consider a bond that promises to pay $100 in one year... If i = 0.28 what is the price of the bond today? Answer:Consider the following numerical model: C=700 + 0.8Y I = 500-2000i+0.1Y G = 400 T = 500 Find the equation for the IS curve (keep in mind that Y=Y-T). If you were to draw the IS curve, what would the intercept (where the IS curve crosses the Y vertical axis) be? (and find the intercept in relation to Y - ie in the form Y=a-bi where a is the intercept) Answer:Consider a bond that promises to pay 100 in one year...
