In this paper, we combine the export-led and import-led growth hypotheses in a growth model in which the importation of foreign capital goods and the demand elasticities of own export products explain the growth opportunities and the technical progress of developing countries. This model, based...

The literature on aid effectiveness has focused more on recipient policies than the determinants of aid allocation yet a consistent result is that political allies obtain more aid from donors than non-allies. This paper shows that aid allocated to political allies is ineffective for growth,...

We propose a framework to analyze convergence between regions, incorporating the public sector and technological knowledge spillovers in the context of a Neoclassical Growth Model. Secondly, we apply novel estimation methods pertaining to the spatial econometrics literature introducing a spatial...

Following Jones and Williams (2000), we assume that R&D is simultaneously subject to positive and to negative external effects (e.g., the non rival nature of technology conflicts with congestion externalities). This observation allows to conceive an economy where two R&D sectors evolve without...

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.

Innovation is the building block of competitive advantages and thus economic policies are increasingly focused on creating stimulus to increase a country’s innovative performance and growth potential, namely through knowledge accumulation in general and R&D in particular. In this context,...

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...
