As people become richer they get the opportunity of consuming more but also qualitatively better goods. This holds for a basic commodity like food as well. We investigate food consumption in Russia, taking into account both expenditure and nutrition value in terms of calories. We analyze how...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors, spanning the space of Engel curves. Once the common factors are estimated via approximate principal components, we identify them by imposing...

Using data spanning over four decades (1960-2000), this paper employs Engel's needsbased approach to analyzing household expenditure patterns to find evidence for the existence of a stable hierarchy of expenditure patterns at low levels of household income. Second, we investigate how rising...

Certain properties of Engel curves have been linked to the occurrence of structural change in the economy (Pasinetti 1981, Metcalfe et al. 2006, Saviotti 2001). From an empirical perspective, however, very little has been done to examine (i) whether indeed satiation is a general property of...

This paper revisits Ernst Engel's (1857) original article in which he systematically investigated the relationship between consumption expenditure and income. While he is mainly remembered today for the discovery of Engel's law, we highlight how Engel addressed in a particular way the issue of...

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...
