This paper presents a dynamic form of the almost ideal demand system (AIDS). The static AIDS model was employed to determine long-run equilibrium model and represents the short-run dynamics by an error correction mechanism. This estimation procedure is applied to estimate three kinds of popular...

This paper estimates the value of water rights in the Phoenix Active Management Area (AMA), Arizona. Within AMAs groundwater rights cannot be transferred separately from the agricultural land to which they apply. As a result there is no separate market for ground water rights. The lack of a...

This study investigates the demand for selected healthy food groups in the United States. The original linear approximate almost ideal demand system (LA/AIDS) is modified by the use of a Laspeyres index and a normalization in order to compute demand elasticities identically to the AIDS model....

Soybeans are one of the most valuable crops in the world and are characterized by their multi-purpose uses: food, feed, fuel and other industrial usages such as paint, inks, and plastics. Out of 183.9 million tons of world supply/demand of soybeans in 2001-03 year, about 10% of them were...

This research develops 'Johansen-type' models of agriculture and constructs Input-Output models for assessing the impact of the post-1992 CAP reforms on incomes, employment and the environment in four Alentejo study areas of Portugal. The effects of agricultural output changes on businesses...

The proposed paper belongs to the literature on food demand and optimal taxation and to the literature dealing with economics of alcohol production and consumption. We investigate the question of optimal taxation for the commodity whose consumption has positive and negative features both for...

The US held the largest share in the Japanese sorghum market for 20 years. However, in recent years Australia’s share of the same market has been constantly growing to claim the top position despite the fact that the US sorghum price is cheaper in that country. The ratio of US vs Australian...

The objective of the study is twofold: first, to investigate whether a nutrition convergence process exists in sub Saharan Africa (SSA) countries, and second, to examine the response of per capita nutrient intake [i.e. calories, proteins and fats] to changes in income (i.e. nutrient-income...
