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,...

This paper investigates the effects of connectivity charges (communication costs) on bilateral exports in Sub Saharan Africa (SSA). Data from 19 exporter countries was used together with communication costs data in a gravity model of trade setup. The export data derive from the IMF Direction of...

This paper is a commentary on a project application of telemedicine to alleviate primary health care problems in Lundazi district in the Eastern province of Zambia. The project dubbed 'The Virtual Doctor Project' will use hard body vehicles fitted with satellite communication devices and modern...

UK climate change policy has long been concerned with the transition to a more sustainable energy mix. The degree of competition in electricity markets rises as these markets become more and more liberalized. In order to survive in such an increasingly competitive setting, electricity producers...

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...

In this paper we discuss the impact of malnutrition on the distribution of abilities and income in a simple overlapping generations framework. Workers are distributed uniformly over a low-ability and a high-ability range. If workers earn below subsistence wages, the probability that their...

In this paper we seek to explain the causes and consequences of Northern penetration in Southern subsistence markets in order to reach the countless masses at the Bottom of the (Income) Pyramid. To this end we formulate a One-North-Many-Souths model, inspired by the Krugman (1979) North-South...

The research reported here gives priority to understanding the inter-temporal resource allocation requirements of a program of technological changes that could halt global warming by completing the transition to a "green" (zero net CO2- emission) production regime within the possibly brief...

Economic growth thus far has been closely linked to the bulk conversion of energy stored in carbon based fuels (wood, coal, oil, natural gas) into useful work. Burning such fuels gives rise to CO2-emissions. These emissions, together with other greenhouse gasses (GHG's) like methane, are now...
