In this paper, we study the existence of an intertemporal equilibrium in a Ramsey model with heterogenous discounting, elastic labor supply and borrowing constraints. Applying a fixed-point argument by Gale and Mas-Colell (1975), we prove the existence of an equilibrium in a truncated bounded...

This paper annalyses the optimal timing of switching between alternative and consecutive regimes on optimal growth models. We derive the appropriate necessary conditions for such problems by means of the standard techniques from calculus of variations and some basic properties of Sobolev spaces.

To account for the development patterns that differ considerably among economies in the long run, a variety of one-sector models that incorporate some degree of market imperfections based on technological external effects and increasing returns have been presented. This paper studies the dynamic...

In transitional stage saving rate play an important role in output growth rate as proposed by Krugman. Accumulationists are also right as claiming that learning-by-doing play an important role in TFP growth in NIEs. However, using a CES production technology we can show that the growth model...

We consider a general equilibrium model in asset markets with a countable set of states and expected risk averse utilities. The agents do not have the same beliefs. We use the methods in Le Van - Truong Xuan (JME, 2001) but one of their assumption which is crucial for obtaining their result...

There are two main approaches for defining social welfare relations for an economy with infinite horizon. The first one is to consider the set of intertemporal utility streams generated by a general set of bounded consumptions, and define a preference relation between them. This relation is...

We consider a developing country with three sectors in economy: consumption goods, new technology, and education. Productivity of the consumption goods sector depends on new technology and skilled labor used for production of the new technology. We show that there might be three stages of...

This paper proves the existence of competitive equilibrium in a single sector dynamic economy with heterogeneous agents and elastic labor supply. The method of proof relies on some recent results concerning the existence of Lagrange multipliers in inï¬nite dimensional spaces and their...

Solowian view on miracle growth rate in NIEs as a result of productivity growth whereas many others (e.g. Krugman [1997]) convince that broad capital accumulation is only true engine underlying NIEs growth. Krugman's view is correct in the short and mid terms, however in the long term, TFP is...

The main contribution of the paper is to provide a weaker nonsatiation assumption than the one commonly used in the literature to ensure the existence of competitive equilibrium. Our assumption allows for satiation points in the set of individually feasible consumptions, provided that the...
