The life-cycle hypothesis predicts that the cross-sectional variance of the marginal utility of consumption is equal to its own lag plus a constant and a random component. Using fairly general preference specifications and some assumptions about the nature of the random component, we provide an...

Several decades of conflict, rebellion and unrest severely weakened civil society in parts of Colombia. Desarollo y Paz is the umbrella term used to describe the set of locally-led initiatives that aim at addressing this problem through initiatives to promote sustainable economic development and...

We study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total expenditure and for the (unobserved) variability of prices across villages, the best fit is provided by a log-linear specification....

We examine the effect of large cash transfers on the consumption of food by poor households in rural Mexico. The transfers represent 20% of household income on average, and yet, the budget share of food is unchanged following receipt of this money. This is an important puzzle to solve,...

In this paper we use an economic model to analyse data from a major social experiment, namely PROGRESA in Mexico, and to evaluate its impact on school participation. In the process we also show the usefulness of using experimental data to estimate a structural economic model. The evaluation...

This research is part of a large evaluation effort, undertaken by a consortium formed by IFS, Econometria and SEI, which has considered the effects of Familias en Acción on a variety of outcomes one year after its implementation. In early reports, we focussed on the effects of the programme on...

In this paper we use the two waves of the British Retirement Survey (1988/89 and 1994) to quantify the relationship between socio-economic status and health outcomes. We find that, even after conditioning on the initial health status, wealth rankings are important determinants of mortality and...

Using three major UK pension reforms as natural experiments we investigate the relationship between pension saving and discretionary private savings. Unlike most differences-in -differences approaches which rely on average differences between the control and the treatment group, we use economic...

The paper studies the effects of Familias en Acción, a conditional cash transfer program implemented in rural areas in Colombia since 2002, on school enrolment and child labour. Using a difference-in-difference framework, our results show that the program increased school participation of 14 to...

In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of preference parameters. When utility is isoelastic and a sample covering a long time period is available, consistent estimates are obtained from the...
