This paper extends the Ramsey-Cass-Koopmans growth model of optimal capital accumulation in discrete time by introducing a generic population growth law that satisfies the following properties: population is strictly increasing and bounded, and the population growth rate is decreasing to zero as...

We analyze how different budgetary rules affect the stability of an economy in a basic endogenous growth model with public debt and a state-dependent consumption tax rate. We show that a discretionary policy implies that the government violates its inter-temporal budget constraint along a...

This paper reformulates the classical Uzawa-Lucas model of economic growth and human capital accumulation by representing time as a discrete variable and using a non-constant population growth rate. In addition, the model is developed with a more general utility function. The study examines the...

We study the impact of intra-industry trade and capital mobility on steady state welfare and on the stability properties of two countries with identical technologies and preferences. We consider a two-factor overlapping generations model, featuring one-sector of differentiated goods with taste...

One of the key elements in any standard economic growth theory is that population growth exponentially at a constant rate n gt; 0. This simple model can provide an adequate approximation to such growth only for the initial period because, growing exponentially, population approaches infinity...

In this paper we consider the entry and exit of RMS in a dynamic general equilibrium model with capital and a XED labour supply. At the firm level, there is a XED cost combined with increasing marginal cost, which gives a standard U-shaped cost curve with optimal firm size. At the aggregate...

This paper reformulates the neoclassical Solow model of economic growth in discrete time by introducing a generic population growth law that verifies the following properties: 1) population is strictly increasing and bounded; 2) the rate of growth of population is decreasing to zero as time tends...

We study the impact of intra-industry trade and capital mobility on steady state welfare and on the stability properties of two countries with identical technologies and preferences. We consider a two-factor overlapping generations model, featuring one-sector of differentiated goods with taste...

This paper examines the stability of balanced paths of expansion or contraction in closed macroeconomic models as typical cases of homogeneous dynamical systems. Examples of known two-dimensional deterministic and stochastic models are discussed. The appendix presents the mathematical tools and...
