Immigration as a source of population growth is traditionally represented by neoclassical growth models with negative output and growth effects in per capita terms for the host economy. The reasoning behind this is the assumption of decreasing returns to labour in the production function. This...

We show that even in the absence of diminishing returns in production and technological spillovers, international trade leads to a stable world income distribution. This is because specialization and trade introduce de facto diminishing returns – countries that accumulate capital faster than...

The neoclassical growth model accords with empirical evidence on convergence if capital is viewed broadly to include human investments, so that diminishing returns to capital set in slowly, and if differences in government policies or other variables create substantial differences in...

This paper integrates in a unified and tractable framework some of the key insights of the field of international trade and economic growth. It examines a sequence of theoretical models that share a common description of technology and preferences but differ on their assumptions about trade...

This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. I show that a...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...

We outline six facts that should be explained by an international growth model: 1) Conditional convergence; 2) cross-country dispersion of growth rates; 3) cross-country dispersion of per capita income levels; 4) cross-country dispersion of savings rates; 5) within country correlation of savings...

The paper examines the welfare gains from North-South trade and their distribution. We construct an endogenous growth North-South model with four Southern stages of development as possible equilibria: specialisation in a traditional good; the South in addition copies Northern high-tech...

Cross-country evidence is presented on resource dependence and the link between volatility and growth. First, growth depends negatively on volatility of unanticipated output growth independent of initial income per capita, the average investment share, initial human capital, trade openness, the...

In this paper, we develop a North-South endogenous growth model to examine three phases of development in the South: imitation of Northern products; imitation and innovation; and finally, innovation only. In particular, the model has the features of catching up (and potentially overtaking),...
