DOI: 10.1007/s40819-019-0687-y
Abstract: Capital $$(k_t,t\ge 0)$$(kt,t≥0) in the Solow growth model solves a nonlinear ODE defined by $$b:[0,\infty )\rightarrow \mathbb {R}$$b:[0,∞)→R where $$b^{\prime }(k)\rightarrow \infty $$b′(k)→∞ as $$k\rightarrow 0^{+}$$k→0+. Macroeconomics states Solow’s ODE has a unique positive equilibrium… read more here.
