Club convergence may arise as an empirical prediction from standard neoclassical growth models where the aggregate production technology displays diminishing returns to capital. This requires that the propensity to save from wage income is greater than the propensity to save from capital income....

Present-biased preferences cause distortions in consumption that can motivate the use of paternalistic in-kind transfers. Empirically, goods are consumed to different degrees when consumption outlay changes. Economists distinguish between necessary goods and luxury goods. A present-biased...

In this paper we develop a theory of scale-invariant endogenous growth. By this we mean a theory capable of generating a balanced growth path where both the growth rate and the level of GDP per capita are independent of the size of population, where population growth is neither necessary nor...

This paper takes a fresh look at two issues in the aid effectiveness debate. We begin by providing theoretical foundations for the various claims made with regard to the effectiveness of aid in stimulating long-run productivity. When foreign aid is modelled as an exogenous transfer of income or...

The so-called "fiscal policy approach predicts that increases in income skewness should be associated with an intensification of redistributive efforts, at least in democracies. If redistribution is detrimental to growth, then this implies that a poor middle class is bad for long-run...

In the present paper the joint determination of long-run income per worker and capital utilization is studied. It is shown that comparatively low (optimal) rates of capital utilization may arise in poor economies in response to weak underlying structural characteristics. Moreover, the...

This paper tackles a number of issues that are central to cross-country comparisons of productivity. We develop a "dual" method to compare levels of total factor productivity (TFP) across nations that relies on factor price data rather than the data on stocks of factors required by standard...

This paper argues that a significant part of measured TFP differences across countries is attributable not to technological factors that affect the entire economy neutrally, but rather, to variations in the structural composition of economies. In particular, the allocation of scarce inputs...

According to much of the recent growth literature the dramatic worldwide fertility decline currently taking place should ultimately lead to global economic stagnation. This pessimistic prediction is not shared by the original innovation-based growth literature. However, this strand of literature...

The so-called “fiscal policy approach" predicts that increases in income skewness should be associated with an intensification of redistributive efforts, at least in democracies. If redistribution is detrimental to growth, then this implies that a poor middle class is bad for long-run...
