COVID-19 had an impact not only on human health but also consumers' food consumption. Employing the Almost Ideal Demand System (AIDS), this study analyzes whether consumers change their demand for between 2019 and 2020 in Japan, where legal action was implemented to restrict consumer behavior. Using home scan data, 25 items, including eating out delivery, were analyzed see of COVID-19. Results ...

The obesity epidemic and excessive consumption of sugar-sweetened beverages have led to proposals of economics-based interventions to promote healthy eating in the United States. Targeted food and beverage taxes and subsidies are prominent examples of such potential intervention strategies. This paper examines the differential effects of taxing sugar-sweetened beverages by calories and by ounce...

Let $R$ be a commutative ring and $I$ an ideal of $R$. The zero-divisor graph of $R$ with respect to $I$, denoted by $Gamma_I(R)$, is the simple graph whose vertex set is ${x in Rsetminus I mid xy in I$, for some $y in Rsetminus I}$, with two distinct vertices $x$ and $y$ are adjacent if and only if $xy in I$. In this paper, we state a relation between zero-divisor graph of $R$ with respec...

Let R be a commutative ring with identity. In this paper we define the notion of almost primary ideal. An ideal of a ring R is said to be an almost primary ideal if for a, b ∈ R with ab ∈ I − I2 then a ∈ I or bn ∈ I for some n ∈ N. We prove that in Noetherian domains almost primary ideals are primary.

Estimation of Theoretically Plausible Demand Functions From U. S. Consumer Expenditure Survey Data Lester D. Taylor University of Arizona The purpose of this paper is the application of four popular theoretically plausible consumer demand systems to a common cross-sectional data set that combines expenditure data from the quarterly BLS consumer expenditure surveys with price data that are colle...

This study estimates the demand for meat in Indonesian urban households encompassing beef, goat, broiler chicken, and native chicken. We estimate using cross-sectional data from 2013 Socio-Economic Household Survey data, which records food expenditure a week before survey. Because of some zero expenditure, Censored Almost Ideal Demand System (AIDS) consistent two-step estimation is applied. The...

The aim of the paper is to explain beef consumption through economic indicators and prediction tendencies consumption. There are countries like Slovakia that confirm opposite trend despite global growth. In terms ecosystems' sustainability, production should be adjusted accordingly, as in case Slovakia. We focus on aspect from perspective sustainability. Commodity prices considered a significan...
