This paper analyses the impact of government R&D on the macro-economy of South Africa. The empirical estimates of the impact of R&D are based on the backward and forward linkages of a macro-economy, within a national innovation system (NIS).

In this paper, we empirically investigate the effect of entrepreneurship on economic growth at the country level. We use data from the Global Entrepreneurship Monitor, which provides comparative data on entrepreneurship from a wide range of countries. An important element of this paper is that...

We show empirically that aid given to poor developing countries enhances growth and reduces emigration once several dynamically interacting effects of aid are taken into account in a system of equations. We estimate equations for net immigration flows as a share of the labour force and GDP per...

This paper develops a model positing a nonlinear relationship between public investment and growth. The model is then applied to a panel of African countries using nonlinear estimating procedures. The growth-maximizing level of public investment is estimated at about 10 percent of GDP based on...

What really makes an economy competitive? This paper reviews and discusses how the capacity to generate, exploit and diffuse new knowledge is key in enabling countries to capitalise on challenges brought about by rapid technology-driven transformations rather than succumb to their adverse...

This paper discusses the progress in transition to knowledge-based economy in Saudi Arabia. As for the methodology, this paper uses updated secondary data obtained from different sources. It uses both descriptive and comparative approaches and uses the OECD definition of knowledge-based economy...

This paper employs both the descriptive and comparative approaches and uses the definition of knowledge and knowledge indicators used in the literature to examine the existence and development of the knowledge economy in the Arab region. We fill the gap in the Arab literature and present a more...
