I develop a growth model in which R&D resources can be directed either to the discovery of new technologies (inventions) or to the improvement of the quality of machines without altering their underlying technology (innovations). Learning-by-doing is an important determinant of the relative share of resources allocated to inventive versus innovative activity. The dynamics generate endogenous ec...

This study builds a multi-sectoral balance-of-payments-constrained growth model that incorporates structural heterogeneity between sectors and countries, such as differences in labor productivity, price competition, shares of exports and imports, and the quality of commodities. The model in the current paper generates more comprehensive results than those presented by Thirlwall (1979), Blecker ...

This study builds a multi-sectoral balance-of-payments constrained growth model that incorporates some structural heterogeneity between sectors and countries, such as differences in labor productivity, price competition, share of exports and imports, and the quality of commodities. The model in the current paper generates more comprehensive results than Thirlwall (1979), Blecker (1998), and Ara...

Technology or lack of it will play an important role in Africa’s effort to achieve inclusive development. Although a key determinant of competitiveness, new technology can exacerbate exclusion of the majority from the mainstream economic activities. To minimise potential technology exclusion while leveraging its critical role in African’s development, requires insight into technology diffusion ...

Integration affects economic growth mainly through two different channels: The scale-effect channel and the factor-reallocation channel. In order to investigate both channels within a unifying framework, we employ a simple descriptive growth model. The scale-effect channel increases either the long-run growth rate or the level of the balanced growth path. The factor-reallocation channel is ambi...

A prototypical vintage capital model of economic growth is developed, where the decision to replace old technologies with new ones is modeled explicitly. Technological change is investment specific. Depreciation in this environment is an economic, not a physical, concept. The vintage capital economy's balanced-growth paths and transitional dynamics are analyzed. The transitional dynamics are ma...

It is well known that the performance of simple models of economic growth improves substantially through the introduction of subsistence consumption. How to compute subsistence needs, however, is a difficult and controversially discussed issue. Here, I reconsider the linear (Ak) growth model with subsistence consumption and show that the evolution of savings rates and economic growth rates over...

We derive an R&D-based semi-endogenous growth model where technological progress depends on the available amount of technological opportunity. Incremental innovations provide direct increases in the knowledge stock but they reduce technological opportunity and thus the potential for further improvements. Technological opportunity can be renewed only by radical innovations (which have no direct ...

This paper explores the growth effects of the enlargement of a common market from two to three countries by making use of a three-country equilibrium growth model with heterogeneous labour. We prove that the enlargement will stimulate the backward countries’ economic growth. In addition, we also demonstrate that the higher the new member country’s average talent level is, the more likely it is ...

The purpose of this thesis is to investigate whether an increase in the level of human capital and reduction of gender inequality in the labor market affect developing nation’s growth rate and welfare. The data used in this thesis cover 74 emerging and developing countries for the years of 2001 and 2007. Solow’s augmented growth model has been used to estimate how increased rates of females and...
