In this paper we develop a two-sector endogenous growth model with a dual labour market, based on efficiency wages. Growth is driven by intentional R&D performed in the high-tech and high-wage sector. It is examined how a change in rivalry among firms affects simultaneously growth and...

One of the most outstanding accomplishments of the economic science over the last decades is the development of a sound and coherent theory of economic growth. Research in growth theory has demonstrated that significant and systematic increases in well-being are attainable whenever the right...

This paper presents a fairly general treatment of recursive infinite horizon forward looking optimizing systems on infinite dimensional spatial domains. It includes optimal control, an analysis of local stability of spatially flat optimal steady states and development of techniques to compute...

In this paper, we apply first and higher-order Euler discretizations to compare dynamic systems in discrete and continuous time. In addition, we stress the difference between backward and forward-looking approximations. Focussing on local bifurcations, we find that time representation is neutral...

In this paper, we analyze government budget balance within a simple model of endogenous growth. For the AK model, simple analytical conditions for a tax cut to be self-financing can be derived. The critical variable is not the tax rate per se, but the "transfer-adjusted tax rate". We discuss...

This paper uses adynamic model to analyse the effects of liberalisation on the long-run output and transitional growth of the Vietnamese rice sector during the period of reform from 1981 to the present. In particular, the paper attempts to allow for the incentive effects which can result if...

This paper provides a framework with which to analyse growth in a small economy with perfect capital mobility. It provides a diagrammatic representation of steady states which differs in interesting and important ways from the usual closed-economy Solow-Swan diagram. The paper also analyses...

It is common to study the asymptotic properties of log-linear stochastic systems by analyzing the behaviour of their linear counterparts. In this paper a formal justification for analysis by log-linearization is given. As an application, a new existence, uniqueness and stability condition is...

We study cycles and chaos in economic models. Autonomous dynamical systems are considered through infinite time horizon optimization models. We first show how endogenous fluctuations arise in a multisector growth model. Secondly, we consider an extension of this model by allowing direct...

We consider infinite horizon variational problems on different spaces of curves in presence of constraints on the state. We establish several necessary conditions of optimality, and give relations between these different problems.
