I use a randomised conditional cash transfer program from Indonesia to provide evidence on peer effects in consumption of poor households.  I combine this with consumption visibility data from Indonesia to examine whether peer effects in consumption differ by a good's visibility.  In line with...

This paper develops a formula for the optimal nonlinear income tax, the terms of which are familiar from the theory of linear income taxation. The development uses the idea of a perturbation of the optimal schedule and is based upon as assumption of differentiability. It is also shown that the...

We examine the effect of shocks to teacher inputs on child performance in school. We start with a household optimization framework where parents spend optimally in response to teacher and other school inputs. This helps to isolate the impact of teachers from other inputs. As a proxy measure for...

Most studies fail to find an impact of school inputs on outcomes such as test scores. We argue that this might be a consequence of ignoring the possibility that households respond optimally to changes in school inputs and thus obscure the real effect of such provision on cognitive achievement....

What drives migration and remittance behaviour in South Africa, and what are the implications for public policy? This paper evaluates existing empirical evidence, posits a simple theoretical model and undertakes a fresh evaluation using longitudinal data spanning 1993 to 2004 from KwaZula-Natal...

In many developing countries, the beneficiaries of transfer programmes are determined by community-based processes, based on some general targeting rules related to needs.  This opens the door for local social and political processes to impact on who gets access.  Despite increasingly large...

This paper explores the extent and nature of gender differences, by age, in household health expenditure allocation.  Using South African data, we adopt a hurdle methodology, constructing a sequence of decision stages (reporting sickness, consulting medical practitioner, incurring positive...

Exploiting new data from a survey and behavioral experiment conducted in Peru we analyze indvidual`s preferences for securing income in old age. We identify a group that is unrationed by the mandate to save in Peru`s pension system, and draw insights from their affiliation and contribution...

Population aging and the burden it imposes on state finances is one of the major economic challenges governments around the world face. Responses are formulated in terms of either increasing employment (for example by raising the retirement age) or increasing productivity (investment in...

The methodology by Lazear and Michael (1988) is used to decompose household expenditures into that for adults and children. Some specific estimation procedures are modified and cross section-time series (panel) data are used to control for household level heterogeneity. In addition, a new and...
