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...

High-Occupancy/Toll (HOT) lanes have become an increasingly prevalent form of congestion management pricing in the U.S. over the past few decades. The success of a HOT facility is dependent on the pricing scheme implemented, which determines the utilization of the HOT lane, and the corresponding congestion relief on the parallel general-purpose (GP) lanes. An additional complexity in determinin...

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...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

Iran has experienced high food prices in recent years. This paper examines the welfare impacts of rising major food groups' prices on Iranian urban households using Quadratic Almost Ideal Demand System (QUAIDS) approach. The elasticity coefficients derived from QUAIDS are used to estimate Compensated Variations (CV).The study uses Iranian Household Expenditure and Income Survey (HEIS) raw data,...

in this paper we establish a characterization of abelian compact hausdorff semigroups with unique idempotent and ideal retraction property. we also introduce a function algebra on a semitopological semigroup whose associated semigroup compactification is universal withrespect to these properties.

Continued growth in international trade and the developing concepts of zoning and risk assessment demand effective assessment of national surveillance and monitoring systems for animal health. The ideal national epidemiological delivery system incorporates surveillance for disease agents, host monitoring and environmental assessment. An extensive veterinary infrastructure is necessary to suppor...
