QUETIDN 3 This question explores some of the points discussed in Topic 3 {Romer model}. It is also designed to test your understanding of Chapter ti of the prescribed textbook. Consider the simple Romer model developed in lectures with the following values for parameters: a": {1.{J3 y = 0.25 f. = Q A, = a a) How fast are ideas growing in this economy in percentage terms? How many workers are being employed in the goods sector? h} Find what the stock of ideas in this economy will he in periods 2111} {r = 201]) and 4D!) [I = 41111]. c} Find an expression for the output per worker in the balanced growth path. What will he the standard of living in periods 200 and 400? d} On a clear graph, plot the trajectory of the log of output per worker through time. e} Now, assume the policy-maker decides to allow lt} extra workers to come from overseas, leading to an increase in the total labour force to LDDD. Show the effects of this change on the growth rate of ideas, as well as the effect on the plot you drew in part (d). Do you notice both a level effect and a slope effect? Note: the change happened at a time t 2? 400. Bear that in mind when showing the effect of the shock in your graph
