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...

How big a boost to long run growth can countries expect from the ICT revolution? I use the results of growth accounting and the insights from a two-sector growth model to answer this question. A two-sector rather than a one-sector model is required because of the very rapid rate at which the...

The UK, with its relatively liberal immigration policies following recent enlargements, has been one of the main recipients of migrants from new EU member states. This paper poses the questions: what is the effect of immigration on a receiving economy such as the UK? Is the effect beneficial or...

This paper develops a North-South product model in which Southern imitation and the North-South flow of foreign direct investment (FDI) are endogenously determined. In the model, a strengthening of IPR protection in the South reduces the rate of imitation, which, in turn, increases the flow of...

The links between trade and growth are examined in a neoclassical model of an open economy in which domestic production requires both domestic and imported inputs. The model shows that trade distortions induced by policies such as tariffs and exchange controls generate cross-country divergences...
