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...

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...

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...

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 United States, we reject the hypothesis that...

For a long time economists have tended to ignore health as a relevant factor of production and important determinant of economic growth. The widely observed positive relationship between health expenditures and economic growth was considered the result of a strong positive income effect....

In this paper, we present a simple endogenous growth model that allows for the occurrence of innovations that can develop into General Purpose Technologies (GPTs), which are the result of basic R&D. The model incorporates the main features of the Romer (1990) model and the Aghion and Howitt...
