In 2014, México imposed a 20% price hike on sugar-sweetened beverages (SSB) to curb its obesity epidemic, paving the road for other Latin-American countries adopt similar measures. This paper estimates beverage demand system with censored Quadratic Almost Ideal Demand system. Our study finds that tax SSB can reduce consumption between 16.6% and 19.0%. Additionally, increase is associated increa...

In this paper, we introduce a new generalization of weakly prime ideals called $I$-prime. Suppose $R$ is a commutative ring with identity and $I$ a fixed ideal of $R$. A proper ideal $P$ of $R$ is $I$-prime if for $a, b in R$ with $ab in P-IP$ implies either $a in P$ or $b in P$. We give some characterizations of $I$-prime ideals and study some of its properties.  Moreover, we give conditions  ...

Given the heterogeneity between Russia and China, we analyze the extent to which income growth as a major driver of nutrition transition has a significant effect on the consumption of different food aggregates. We estimate expenditure elasticities of nine different food aggregates for China and Russian, applying a Quadratic Almost Ideal Demand model. Our results indicate that future income grow...

Two different methods of incorporating advertising effects into Almost Ideal Demand Systems (AIDS) are presented. Both advertising schemes are designed to allow theoretical restrictions to hold globally rather than at particular sample points. The models are estimated for California figs, prunes, and raisins. Empirical results indicate that generic advertising effects for these three dried frui...

This paper examines how the patterns of India’s food consumption have been changing in recent times as a consequence of her faster economic growth and generally rising affluence levels. The study, also, presents evidence on the nutritional implications of these changes to reinforce some of the findings on the observed changes in the food consumption patterns. The exercise estimates the Quadrati...

This article considers interaction among participation in the Food Stamp Program (FSP), food security status, and the composition of food expenditures. A quadratic almost ideal demand system with a bootstrapping two-step method of estimation is applied to data from the Current Population Survey–Food Security Supplement data and used to estimate the model and account for endogeneity between the ...

In this study, we used a household level survey to assess choices of varieties and demand for improved cassava varieties. A multivariate probit model was examine the determinants choice decisions farmers different preventing potential endogeneity measurement error. Linearized Almost Ideal Demand System (LA/AIDS) analyze system The results indicated were very price sensitive changes in stem pric...

Through this paper, we have attempted to model the demand for di¤erent classes of antibiotics used for respiratory infections in outpatient care in Switzerland using a spatial version of the linear approximate Almost Ideal Demand System (AIDS) model. This model takes spatial dependency into account by means of spatial lags of antibiotic budget shares. We control for the health status of patient...
