Foreign technology imports and economic growth in developing countries

The authors investigate the relationship between foreign technology imports and economic growth in developing countries. They develop an intertemporal endogenous growth model that explicitly accepts foreign technology imports as a factor of production. The model establishes a link between the growth rate of productivity in a developing country and the country's intensity of learning to use foreign technologies. They hypothesize that a developing country's economic growth rate increases as foreign technology imports increase. They run regressions with data for about 50 developing countries, using different econometric methods and time spans. These empirical tests confirm the hypothesis that foreign technology transfers boost income growth rates. Moreover, economic developing in developing countries differs from that in industrial countries. In developing countries, increases in productivity depend not on innovation but on importing foreign plants and equipment and on borrowing foreign technology.Economic Theory&Research,Environmental Economics&Policies,Achieving Shared Growth,Economic Growth,Inequality

On invariant measures and the asymptotic behavior of a stochastic delayed SIRS epidemic model

This article is a total of 20 pages and contains 5 figures.In this paper, we consider a stochastic epidemic model with time delay and general incidence rate. We first prove the existence and uniqueness of the global positive solution. By using the Krylov-Bogoliubov method, we obtain the existence of invariant measures. Furthermore , we study a special case where the incidence rate is bilinear with distributed time delay. When the basic reproduction number R0 1, we prove that the invariant measure is unique and ergodic. The numerical simulations also validate our analytical results
