The arrows denote the dynamic behavior of ct and kt . This depends on which of four possible regions the economy is in. To the northeast, but on the line SS, consumption is excessive and the capital stock is so large that the marginal product of capital is less than δ + θ. This is not sustainable and therefore both consumption and the capital stock must decrease.
For example, if there is a constant population N, then yt = Yt /N is output per capita, where Yt is total output for the whole economy. Output and investment can be eliminated from the subsequent analysis, and the model reduced to just one equation involving two variables. Combining the three equations gives the economy’s resource constraint: F (kt ) = ct + ∆kt+1 + δkt . 4) This is a nonlinear dynamic constraint on the economy. ✐ ✐ ✐ ✐ ✐ ✐ “wickens” — 2007/10/15 — 13:08 — page 14 — #32 ✐ 14 ✐ 2.
This induces a rise in investment above its normal replacement level δk. Initially, kt remains unchanged and so the economy moves to point B. New investment increases the capital stock each period until the economy reaches its new long-run equilibrium at C by moving along the saddlepath from B. At this point qt is restored to its long-run equilibrium level of one and the equilibrium capital stock, output, and consumption are permanently higher. 2 Time to Build An alternative way of reformulating the basic model that results in more general dynamics is to assume that it takes time to install new investment.
