"Neo" means "new" - the neo-classical growth theory is a "new version" of the classical growth model. Neoclassical models of growth (including endogenous growth models) see education as promoting growth by making the productivity of labor increase more rapidly, and improving income distribution by increasing wages, although different rates of skill formation – through education – between different groups are sometimes argued to exacerbate income inequality. Transitional dynamics in the baseline neoclassical growth model. Our goal is to provide macroeconomists with a toolkit of models that are of interest in their own right, and that easily can be modi–ed to study a broad variety of macroeconomic phenomena, including the impact of economic policies on aggregate economic activity. Aggregate Models Will shift from detailed analyses of separate components of economy to abstract model of economy.
