We consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects. We show that indetermincay of steady states and cycles can easily arise with constant or decreasing social returns to scale, and very small market imperfections. This is in sharp contrast...

We consider an overlapping generations model of small open economy with Harrod neutral technical progress. If the interest rate is less that the growth rate, intergenerational public transfers increase welfare of some generations and reduce welfare of others.

This paper analyzes the macroeconomic effects of the patent system within the framework of an endogenous growth model with new products development. We assume that patents not only represent a commercial protection for innovators but also entail a partial property right on information.

This paper discusses the influence of technological externalities on the dynamic properties of accumulation paths in a two-sector growth model in discrete time.

We construct a R&D based endogenous growth model within an overlapping generations framework. We study the properties of the long run growth rate. We define endogenous growth as an equilibrium in which the long run growth rate is always stricly larger than zero. Then, we show that endogenous...

This article is interested in the scope for indeterminacies that originate from capital stock externalities in the technological set of the reference model of the multisectoral optimal growth literature. Sufficient conditions for local indeterminacies and oscillations are established and rest on...

This paper analyzes the role of the structure of skills in economic development through investment in human capital. With a lack of credit market for education and the presence of indivisibilities in investment in human capital as well as of a congestion effect of the educational system, the...

We build an OLG model with productive capital in which agents live for two periods and display myopia in their altruistic bequest motive. Indeed , they care for their children's welfare like Barro-Becker altruists but what they value is income. A govern,emt redistributes income from the young to...

We compare the dunamics under myopic foresight and under perfect foresight in an overlapping generations model with capital accumulation and two-period lived individuals. When the rational dynamics are defined and the myopic dynamics are monotonic, the study of myopic foresight allows to...
