Engel's law is known to be extraordinarily consistent across time and space. Accordingly, it has been widely used to determine poverty. However, also among the poorest, a certain amount of non food spending is necessary. To substantiate the distinction between necessities and luxuries, already...

Accurate and timely measures of cross-country real incomes are still a rarity. As the share of expenditure devoted to food is readily available, we use of Engel's law in reciprocal form to measure affluence. Analysis of real income data for the OECD countries indicates that this approach is...

Dietary choices are one of the main causes of mortality and environmental degradation. Plant-based diets, in comparison to diets rich in animal products, are considered to be more sustainable because they use fewer natural resources and come with a lower environmental burden, resulting in lower...

Estimating future demand for food is a critical aspect of global food security analyses. The process linking dietary changes to wealth is known as the nutrition transition and presents well-identified features that help to predict consumption changes in poor countries. This study proposes to...

There are significant disparities in the wealth of nations and how incomes are spent. For example, consumers in the poorest countries spend more than half of income on food, whilein the richest countries, this is one-tenth or less. We use the recently published data from theInternational...

Engel's law is known to be extraordinarily consistent across time and space. Accordingly, it has been widely used to determine poverty. However, also among the poorest, a certain amount of non food spending is necessary. To substantiate the distinction between necessities and luxuries, already...

We provide consistent, cross-country estimates of price and income elasticity for 11 OECD countries, using data from a survey conducted by the OECD in 2011. Using data for annual consumption of electricity and sample-derived average electricity price, we provide country specific price elasticity...

Background: This paper contributes to the evidence-base on prices and alcohol use by presenting meta-analytic summaries of price and income elasticities for alcohol beverages. The analysis improves on previous meta-analyses by correcting for outliers and publication bias.Methods: Adjusting for...
