The half life, tlfiz. is the time it takes to reduce gap(0) by a factor of two. The half life solves the equation % : ett/Z/T and for the capital accumulation equation is In the prior slide 35 = 0.02, g; = 0.02, 5 = 0.08. and a = 0.3. The half life for this shock is 8.25 years. By how much does the half-life shown on slide 10 of lecture 6 change if 93 doubles
