In this article we propose a method for solving a general class of four-dimension nonlinear modified Hamiltonian dynamic systems in closed form. This method may be used to study several intertemporal optimization problems sharing a common structure, which involves unbounded technological...

In this paper, we intend to offer a critical review of the different concepts of capital and the different methods which are used to measure it. At the same time, we propose an endogenous approach which tries to measure the capital stock in terms of value, explicitly referring to depreciation as...
