in this article, optimal vat rates have been calculated for the three different levels of consumption tax revenue needed by the government. using the data of 10 income groups of the iranian rural and urban households in the period(1378-1386) and applying panel data approach, the almost ideal demand system(aids) were estimated to derive the price and income elasticities. then, the optimal vat ra...

the purpose of this paper is measuring and analyzing the impacts of meat price changes on consumer’s welfare. first, the almost ideal demand system (aids) was estimated for meats in urban household in 1984-2009 years. then, compensating variation (cv) criterion was computed to measuring the consumer’s welfare changes based on taylor series expansion method and the results from the estimated aid...

In this article, we introduce a new class of ideal convergent sequence spaces using an infinite matrix, Musielak-Orlicz function and a new generalized difference matrix in locally convex spaces. We investigate some linear topological structures and algebraic properties of these spaces. We also give some relations related to these sequence spaces.

The recent global financial problem urges government to play role in stimulating the economy due to the fact that private sector has little ability to purchase during the recession. A concerned question is whether the increased government spending crowds out private consumption and whether it helps stimulate the economy. If the government spending policy is effective; the private consumption is...

The ideal analysis of planar diodes in Temperature Limited Region is presented. Two types of relations are obtained for electric potential and electric field distributions one accurate but implicit and the other almost accurate but explicit.

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...
