Quality of Knowledge Technology, Returns to Production Technology and Economic Development

VAN, Cuong LE; SAGLAM, H. Cagri - Institut de Recherche Économique et Sociale (IRES), … - 2001

Presenting a discrete time version of the Romer (1986) model, this paper analyzes optimal paths in a one-sector growth model when the technology is not convex. We prove that for a given quality of knowledge technology, the countries could take-off if their initial stock of capital are above a...

Lead-lag cross-sectional structure and detection of correlated–anticorrelated regime shifts: Application to the volatilities of inflation and economic growth rates

Zhou, Wei-Xing; Sornette, Didier - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 287-296

We have recently introduced the “thermal optimal path” (TOP) method to investigate the real-time lead-lag structure … between two time series. The TOP method consists in searching for a robust noise-averaged optimal path of the distance matrix …

Transition between strong and weak disorder regimes for the optimal path

Sreenivasan, Sameet; Kalisky, Tomer; Braunstein, Lidia A.; … - In: Physica A: Statistical Mechanics and its Applications 346 (2005) 1, pp. 174-182

We study the transition between the strong and weak disorder regimes in the scaling properties of the average optimal … path ℓopt in a disordered Erdős–Rényi (ER) random network and scale-free (SF) network. Each link i is associated with a …

Length of optimal path in random networks with strong disorder

Buldyrev, Sergey V.; Braunstein, Lidia A.; Cohen, Reuven; … - In: Physica A: Statistical Mechanics and its Applications 330 (2003) 1, pp. 246-252

We study the optimal distance ℓopt in random networks in the presence of disorder implemented by assigning random weights to the links. The optimal distance between two nodes is the length of the path for which the sum of weights along the path (“cost”) is a minimum. We study the case of...

The discrete time version of the Romer model

Morhaim, Lisa; Dimaria, Charles-Henri; Van, Cuong Le - In: Economic Theory 20 (2002) 1, pp. 133-158

This paper presents a discrete time version of the Romer 1986 model of endogenous growth. The purpose of this work is to propose detailed and simple proofs of existence of optimal solutions and of a competitive equilibrium. The framework implemented here reduces the complexity of the proofs...
