This paper investigates whether the inherent non-stationarity of macroeconomic time series is entirely due to a random walk or also to non-linear components. Applying the numerical tools of the analysis of dynamical systems to long time series for the US, we reject the hypothesis that these...

In this paper we show the benefits of regional connectivity and specialization to growth. Starting with one region we show how welfare measured by utility per head increases as the number of connected regions increase. We assume a common connectivity infrastructure implemented by satellite,...

We use Financial Optimum Portfolio Theory to obtain Optimum Development (Policy) Portfolios for Sub Saharan African (SSA) Countries. We estimate a model linking public expenditures on health, education and general government expenditures to the Human Development Index (HDI). Given the...
