Quadratic Engel Curves and Consumer Demand
This paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices. A nonparametric analysis of consumer expenditure patterns suggests that Engel curves require quadratic terms in the logarithm of expendit...
متن کاملConsumer Demand and Intertemporal Allocations: Engel, Slutsky, and Frisch
Individual consumers often are assumed to follow certain relatively simple budgeting rules when making expenditure decisions. For example, how much to save may be decided upon almost separately from decisions on how much to spend on food, services, and other day-to-day consumables. Of course, it is well known that such "decentralized" budgeting decisions can fit well within standard consumer th...

متن کاملWhen Does Food Stop Being a Luxury? Evidence from Quadratic Engel Curves with Measurement Error
Using quadratic Engel curves with measurement errors, we identify the proportion of urban households in Ethiopia for whom food exhibits the characteristics of a luxury commodity. The threshold welfare level beyond which food ceases to be a luxury is found to lie between the 35 and 47 percentiles of the total expenditure distribution. This suggests that policy aimed at reducing food poverty shou...
متن کاملQuadratic Food Engel Curves with Measurement Error: Evidence from a Budget Survey
In this paper we estimate quadratic food Engel curves with measurement error using the 1994 Ethiopian Urban Household Budget Survey. In sharp contrast to the findings from developed countries, food share is found to increase with expenditure, and only starts to decline after some threshold level of expenditure. We establish the robustness of this inverted-U relationship by estimating a more fle...
