Engel’s Law Reconsidered

چکیده
How this statement should be interpreted? Clearly, it refers to income or total expenditure and budget shares for food (food share for short) for different households in a given population at a given period and not to changing (different) income of a given household. Food share is sometimes defined as consumption expenditures in current prices on food items divided by income but also by consumption expenditure on food divided by ‘total expenditure’ which is defined as expenditures on a well-specified large class of consumption goods and services.

At the Origins of Engel Curves Estimation
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 the relation between statistical empirical analysis and economic theorizing. Inspired by an inductive ...

متن کاملSchumpeterian Entrepreneurs Meet Engel’s Law: The Impact of Inequality on Innovation-Driven Growth
This paper analyzes the impact of inequality on growth when technical progress is driven by innovations and consumers have hierarchic preferences. Inequality has an impact on growth because it affects the structure and the dynamics of demand. Redistribution from very rich to very poor consumers is beneficial for growth. In general, the growth effect depends on the nature of redistribution. Due ...
