Solve for the equilibrium values of g and the fraction of the labor force employed in research (Ln/L). Discuss the determinants of the equilibrium growth rate and the impact on both variables of an increase in the size of the labor force, L. Consider also the effects of "merging" two isolated economies into a larger, integrated one. Does anything change? To
what extent is the answer to this question sensitive to the details of the specification we have used?
