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...

We derive the central differential equation of the neoclassical growth model for the case of a CES (constant elasticity of substitution) production function with perfect capital movement in terms of the debt/GDP ratio and estimate it in several ways for the United States and in a later step the...

A major international transmission channel of productivity increases is trade in intermediate products and services. This paper analyses international spillovers at the industry level and for the first time investigates effects from the services sector in this framework. The analysis makes use...

The success of nations in the path towards economic development hinges heavily on the emergence and dynamism of a modern sector capable of simultaneously absorbing an increasing share of the labour force while reducing the technological gap with the worlds frontier. Failure to do so would...

This paper offers a unified framework to explore both the static and dynamic welfare effects of trade and multinational production MP in the presence of firm-specific productivity heterogeneity. The model captures the dynamic effects by allowing for RD spillovers between firms in a framework of...

Abstract. The debate about the Prebisch-Singer thesis has focused on primary commodities with some extensions to manufactures. As we think that the link between the terms of trade and long-run development, growth and convergence is the ability of exports to enhance investment through importing...

The debate about the Prebisch-Singer thesis has focused on primary commodities with some extensions to manufactured goods. We analyse trends in country terms-of-trade for goods and services rather than those for commodities according to the World Bank income classification. We find that the...

This paper defines economic slumps as a sequence of structural breaks exhibiting a specific pattern. We identify 58 such episodes between 1950 and 2008 among a large sample of countries, and then examine the phases of decline. In several countries declines last extremely long, and we suggest...
