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

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

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...

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...

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...

Extrinsic motivations like intellectual property protections and fiscal incentives continue to occupy the centre stage in debates on innovation policies. Joseph Schumpeter had, however, argued that the motive to accumulate private property can only explain part of innovative activities. In his...
