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...

Spatiotemporal dynamics are introduced in a standard Ramsey model of optimal growth in which capital moves toward locations where the marginal productivity of capital is relatively higher. We extend Pontryagin s maximum principle to account for transition dynamics governed by a nonlinear partial...

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 work we deal with the Solow-Swan economic growth model, when the labor force is ruled by the Malthusian law added by a constant migration rate I. Considering a Cobb-Douglas production function, we prove some stability issues and find a closed-form solution for the emigration case,...

This paper presents a Solow Growth Model with the labor force ruled by the logistic equation added by a constant migration rate, I. We prove the global asymptotic stability of the capital and production per capita. Considering a Cobb-Douglas production function, we show this model to have a...

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...
