Since 1950, there has been considerable diversity in developing country experiences. Some countries and some regions have experienced rapid growth and catch up, others have fallen behind. At a global level there is an increasing inequality of per capita incomes. However, within the framework of...

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...

National framework conditions mediate the effect of technological capabilities of firms on their productivity. Although this has been recognized in the literature for a long time, a quantitative test that explicitly considers this hypothesis has been lacking. Using a World Bank datasets of about...

We examine the contribution of incremental and radical innovations to total factor productivity (TFP) growth at the firm level. The first part of our analysis is dedicated to the determinants of innovation and reveals two different innovation regimes. On the one hand, radical innovations rely...

This paper develops a simple and practical framework for characterizing (long-run) economic growth and fluid capital accumulation under shifting technological change. The framework specifies a technological change that depends on exogenous and endogenous factors as well as the interaction...

Data on physical capital are an indispensable part of economic growth and efficiency studies. In the case of China, economy-wide fixed asset series are usually derived by aggregating gross fixed capital formation (net of depreciation) over time, and sectoral/ownership-specific series by...
