This paper argues that spacing between consecutive births is an important aspect of competition among siblings for survival. Since parents simultaneously choose their desired values of birth spacing and the amount of time and other resources invested in children (which in turn affect child...

This paper studies the relationship between NSF funding and the publications of US economists using data on 1473 applications to NSF during 1985-1990, 414 of which were awarded a research grant. We first outline a basic methodology for assessing the impact of the NSF support for basic research...

This paper investigates whether firms innovate persistently or discontinuously over time using an innovation panel data set on German manufacturing and service firms for the period 1994-2002. We find that innovation behaviour is permanent at the firm-level to a very large extent. Using a dynamic...

We study the behavior of real exchange rates in a two­country dynamic equilibrium model. In this model, consumers can only consume domestic goods but can invest costlessly in capital stocks of both countries. Nevertheless, transporting goods between the two countries is costly and, hence, the...

Using nonlinear unit root tests developed by Kapetanios et al. (2003), we find strong evidence that the Consumer Price Index (CPI) and Wholesale Price Index (WPI) based Malaysian Ringgit – U.S. Dollar (MYR/USD) real exchange rates are nonlinear stationary, implying that MYR/USD nominal...

This paper was produced for the El-Naschie Symposium on Nonlinear Dynamics in Shanghai in December 2005. In this paper we provide a review of the literature with respect to fluctuations in real systems and chaos. In doing so, we contrast the order and organization hypothesis of real systems with...
