Households commonly utilize strategies that provide long-term savings on everyday purchases in exchange for an increase in their short-term expenditures. For example, they buy larger packages of non-perishable goods to take advantage of bulk discounts, and accelerate their purchases to take...

This paper investigates potential measurement error biases in estimated poverty transition matrices. We compare transition matrices based on survey expenditure data to transition matrices based on measurement-error-free simulated expenditure. The simulation model uses estimates that correct for...

While household well-being derives from long-term average rates of consumption, welfare comparisons typically rely on shorter-duration survey measurements. We develop a new strategy to identify the distribution of these long-term rates by leveraging a large-scale randomization in Iraq that...

Poverty measures in developing countries often ignore the distribution of resources within families and the gains from joint consumption. In this paper, we extend the collective model of household consumption to recover mother's, father's and children's shares together with economies of scale,...

To combat growing levels of obesity, health related taxes have been suggested with taxes on foods high in fat or sugar. Such taxes have been criticised on the basis of their regressivity and potentially adverse impact upon poverty. This paper analyses the effect of such taxes on a range of...

The composition of tax revenue in Ireland had changed dramatically over the past decade, with indirect taxes accounting for a large share of total tax revenue. This shift towards indirect taxation more than direct taxation tends to put excessive burden on the poor, thereby raising the concern...

This paper investigates how two effects drive wedges between nominal and real inequality estimates. The effects are caused by (i) differences in the composition of consumption over the income distribution coupled with differential inflation of consumption items; and (ii) quantity discounting...

Evidence suggests that household responses to price and income changes are significantly sensitive across income levels and rural-urban location. In this paper, we focus on poor households vs. non-poor households using two definitions of poverty, objective and subjective. We evaluate the...

This paper explores the feasibility of calculating absolute poverty lines on the basis of minimum food expenditures in developed countries. It makes three important contributions. First, it demonstrates that standard statistical methods used in the developing world deliver either inadequate...
