ON THE MANY FUNDS OF GROWTH - A NOTE

In this note we synthesize exogenous and endogenous sources of economi c growth in a stochastic dynamic log linear general equilibrium model. Endogenous growth could be the result of internal constant returns to scale, external increasing returns to scale in the production of huma n capital or in the production of goods. We get a closed form log line ar representation for the dynamic laws of motion for the human and phy sical capital stocks. Using the solution we distinguish between differ ent sources of growth that combine exogenous technical progress with e ndogenous sources of growth that jointly can generate many possible pa tterns of economic growth.
