The Hamilton method for estimating CPI bias is simple, intuitive, and has been widely adopted. We show that the method confiates CPI bias with variation in cost-of-living across income levels. Assuming a single price index across the income distribution is inconsistent with the downward sloping...

Standard economic theory implies that the labelling of cash transfers or cash-equivalents (e.g. child benefits, food stamps) should have no effect on spending patterns. The empirical literature to date does not contradict this proposition. We study the UK Winter Fuel Payment (WFP), a cash...

We merge detailed household level expenditure data from older households with historical local weather information. We then test for a heat or eat trade off: do houseolds cut back on food spending to finance the additional cost of keeping warm duing cold shocks? We find evidence that the poorest...

The combination of credit constraints and indivisible consumption goods may induce some riskaverse individuals to play lotteries to have a chance of crossing a purchasing threshold. One implication of this is that income effects for individuals who choose to play lotteries are likely to be...

We merge detailed household level expenditure data from older households with historical local weather information. We then test for a heat or eat trade off: do households cut back on food spending to finance the additional cost of keeping warm during cold shocks? For households who cannot...

This report looks at the level of wealth and the rate of saving of households in the UK on the eve of the global economic crisis. Our approach is to use microdata sources to look at the extent to which wealth holdings and saving rates vary across individuals. We use the British Household Panel...

The combination of credit constraints and indivisible consumption goods may induce some risk-averse individuals to gamble to have a chance of crossing a purchasing threshold. One implication of this is that income effects for individuals who choose to gamble are likely to be larger than for the...
