1. Show that from k = K/L it follows k/k=K/K-L/L. (Hint: You can do the 'log-dif-trick', that is, first take logs on both sides of k = K/L and then differentiate with respect to time.) Then show that the Solow model in continuous time implies the Solow equation: k=sBk - (n+8)k. (41) Compare with (32) for the model in discrete time and give an intuitive explanation like the one given for (32) in this chapter.
