On The Empirics of Foreign Aid and Growth,

THE ECONOMIC JOURNAL, Issue 496 2004
Carl-Johan Dalgaard
The present paper re-examines the effectiveness of foreign aid theoretically and empirically. Using a standard OLG model we show that aid inflows will in general affect long-run productivity. The size and direction of the impact may depend on policies, ,deep' structural characteristics and the size of the inflow. The empirical analysis investigates these possibilities. Overall we find that aid has been effective in spurring growth, but the magnitude of the effect depends on climate-related circumstances. Finally, we argue that the Collier-Dollar allocation rule should be seriously reconsidered by donor agencies if aid effectiveness is related to climate. [source]


A Dynamic Incentive-Based Argument for Conditional Transfers,

THE ECONOMIC RECORD, Issue 2008
DILIP MOOKHERJEE
We compare the long-run effects of replacing unconditional transfers to the poor by transfers conditional on the education of children. Unlike Mirrlees' income taxation model, the distribution of skill evolves endogenously. Human capital accumulation follows the Freeman,Ljungqvist,Mookherjee,Ray OLG model with missing capital markets and dynastic bequest motives. Conditional transfers (funded by taxes on earnings of the skilled) are shown to induce higher long-run output per capita and (both utilitarian and Rawlsian) welfare, owing to their superior effect on skill accumulation incentives. The result is established both with two skill levels, and a continuum of occupations. [source]


Altruism and Determinacy of Equilibria in Overlapping Generations Models with Externalities

THE JAPANESE ECONOMIC REVIEW, Issue 2 2003
Alain Venditti
This paper deals with an OLG model with production and a single commodity, in which agents are assumed altruistic and the aggregate production function contains external effects. I prove that, if the technology satisfies a minor assumption, which encompasses positive and negative externalities, some curvature conditions on the utility function ensure local determinacy of stationary and period 2 equilibria. I prove that non-separable, strictly concave preferences are a fundamental ingredient for the occurrence of indeterminate equilibria. Finally, considering the case of unbounded growth, I establish that for any utility and production functions a unique balanced growth path is globally determinate.

RECTANGULARIZATION AND THE RISE IN LIMIT-LONGEVITY IN A SIMPLE OVERLAPPING GENERATIONS MODEL*

THE MANCHESTER SCHOOL, Issue 1 2009
GREGORY PONTHIERE
Whereas overlapping generations (OLG) models with endogenous longevity do not distinguish between the rectangularization phenomenon and the rise in limit-longevity, these constitute two different demographic phenomena requiring a distinct modelling. This paper presents a two-period OLG model where the probability of survival from the first to the second period, as well as the maximum length of life, are endogenously determined and influenced by public policies. The issues of existence, uniqueness and stability of a steady state are studied. It is shown that the transition towards the steady state exhibits, under mild conditions, the observed succession of phases of rectangularization and derectangularization of survival curves. [source]
