This paper aims at assessing the robustness of demographic projections to different assumptions on mortality, fertility and migration. It builds on a small-scale simulation model for 23 OECD countries, which reproduces closely national projections under similar demographic assumptions. Up to...

The main objective of this paper is to study the relationship between external public debt and equilibrium real exchange rate in developing countries. Using a extension of Obstfeld & Rogoff (1995) model we show that debt overhang tend to appreciate real exchange rate in the long run (Krugman...

We present an econometric analysis of the effect of long term nutritional conditions on school achievement. We control potential selectivity bias, which is common in this literature, (i) either by restricting the sample, (ii) or by applying a two step Heckman procedure. For Malagasy data, we...

This paper analyses the impact of health, pension systems and longevity on savings. It uses a simple life-cycle model embodying social transfers (health care and pension expenditures) and changes in longevity to determine the level of household savings. From this model, we derived an econometric...

While the empirical evidence tends to support some predictions of the life-cycle theory, a number of puzzles remain: an ageing-consumption, an ageing-saving, a saving-capitalisation and a saving-longevity puzzles have been put forward in the literature. This paper analyses the links between...
