Economists routinely make functional form assumptions about consumer demand to obtain welfare estimates. How sensitive are welfare estimates to these assumptions? We answer this question by providing bounds on welfare that hold for families of demand curves commonly considered in different...

There is a growing momentum to base the poverty line on total consumption expenditure as it is a better measure of welfare. This chapter explores three related approaches to measuring household welfare that together represent an alternative ‘inductive’ measuring approach. We focus on...

The complexity of the modern world imposes significant cognitive and material costs on consumers. This paper models decision costs to better describe and understand the effects of behavioural policy, and finds that, similar to traditional economic policy, behavioural policies can create welfare...

Using a collective model of consumption, we characterize optimal commodity taxes aimed at targeting specific individuals within the household. The main message is that distortionary indirect taxation can circumvent the agency problem of the household. Essentially, taxation should discourage less...

This paper presents a formal model in which differential satiation dynamics of various consumer needs translate into long-run changes of consumer behavior when income rises. In the model individuals allocate their income to the consumption categories proportional to need deprivation states...

Equivalence scales are routinely applied to adjust the income of households of different size and composition. Because of their practical importance for the measurement of inequality and poverty, a large number of methods for the estimation of equivalence scales have been proposed. Until now, no...
