Growth without Scale Effects

Growth: With or Without Scale Effects?

The discovery of new ideas is the engine of growth in many recent growth models. As emphasized by Paul Romer (1986, 1990), ideas are different from most goods analyzed in economics in that they are nonrivalrous: the use of an idea by one person does not preclude, at a technological level, the simultaneous use of the idea by another person, or even by many people. This leads to a tight link betw...

Scale-free networks without growth

In this paper, we proposed an ungrowing scale-free network model, indicating the growth may not be a necessary condition of the self-organization of a network in a scale-free structure. The analysis shows that the degree distributions of the present model can varying from the Poisson form to the power-law form with the decrease of a free parameter α. This model provides a possible mechanism for...

Fluctuations in Convex Models of Endogenous Growth I: Growth Effects∗

Is there a trade-off between fluctuations and growth? The empirical evidence is mixed, with some studies finding a positive relationship, while others find a negative one. Our objectives in this paper are to understand how fundamental uncertainty can affect the long run growth rate, and to identify those factors that are important in determining the nature of this relationship. Qualitatively, w...

Patterns of technology, industry concentration, and productivity growth without scale effects

This paper investigates the relationship between geographic patterns of industry and economic growth in a two-country model of trade with no scale effect, where productivity growth is generated by firm investment in process innovation. We find that dispersed equilibria with industry located in both countries produce higher growth rates than concentrated equilibria with all industry located in o...
