A reorientation toward emphasis on consumption has become a major issue in China, raising the question of the relation between economic growth and the composition of output. The issue is addressed here, using insights from economic growth theories. These theories indicate that concentration on...

Portfolio turnpikes state that, as the investment horizon increases, optimal portfolios for generic utilities converge to those of isoelastic utilities. This paper proves three kinds of turnpikes. In a general semimartingale setting, the abstract turnpike states that optimal final payo ffs and...

The dynamics of a welfare maximizing heterogeneous agent, one sector optimal Ramsey model is analyzed assuming two agents, each with a distinct discount factor and log utility. Production is Cobb-Douglas. Explicit time-varying policy functions are derived, one for each period. A Twisted Turnpike...

In Section 1, we explain the neoclassical optimal growth model, which includes multi capital goods, and is derived from neoclassical production functions; the transformations to the reduced model are also explained. Section 2 pertains to the explanation of the methods for proving the consumption...
