In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

Many literatures investigate the causal impact of income on economic outcomes, for example in the context of intergenerational transmission or well-being and health. Some studies have proposed to use employer wage differentials and in particular industry affiliation as an instrument for income....

In a model where patients face budget constraints that make some treatments unaffordable, we ask which treatments should be covered by universal basic insurance and which by private voluntary insurance. We argue that both cost effectiveness and prevalence are important if the government wants to...

We develop a new methodology to compute differences in the expected longevity of individuals who are in different socioeconomic groups at age 50. We deal with the two main problems associated with the standard use of life expectancy: that people's socioeconomic characteristics evolve over the...

Using exceptionally rich linked administrative and survey information on German welfare recipients we investigate the health effects of transitions from welfare to employment and of assignments to welfare-to-work programmes. Applying semi-parametric propensity score matching estimators we find...

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....

Increases in human stature are seen as a key indicator of improvement in the average health of populations. The literature associates stature with a variety of socioeconomic variables, and much of the focus is on the nineteenth century and on the last 50 years. In this paper I present and...

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UA) system. Under the UA system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during...

The paper studies the effects of Familias en Acción, a conditional cash transfer programme implemented in rural areas in Colombia in 2002, on school enrolment and child labour. Using a quasi-experimental approach, our methodology makes use of an interesting feature of the data, which allows us...

The paper develops a new approach to measuring the impact of government cash transfers on poverty alleviation that takes into account endogenous reactions and consumption smoothing of households. We use the methodology to study the impact of changes in government cash benefits on poverty rates...
