In the usual setup, time is continuous starting, for simplicity, at and continuing forever. By assumption, the only productive factors are capital and labour , both required to be nonnegative. The labour force, which makes up the entire population, is assumed to grow at a constant rate , i.e. , implying that with initial level at . Finally, let denote aggregate production, and denote aggregate consum… WebTo –nd the saddle path, we set c1 = 0: We obtain xt = x + e21c2 t2; yt = y + e22c2 t2: The saddle path is xt x = e21 e22 (yt y ): The slope of the saddle path is the same as the slope …
