current article is allocated to the report of a research in which the income elasticities of urban families” demand for public education in time period of 2008-2013 were estimated separately according to the income deciles and by applying rotterdam demand system, it was clarified that public education is normal commodity. different size of estimative elasticities indicated that public education...

almost ideal demand system (aids) and rotterdam model have been employed to (by means of seemingly unrelated regression (sur) estimate the function related to milk and dairy products in the urban societies of iran for years 1982 to 2009. cross and cross price elasticities have been evaluated too. results indicated that during the study period, share of milk products in household budget was more...

The focus of recent research on disruption management in public transportation networks more and more shifts from operator-related aspects to improving the service quality. It is, however, not yet well understood how the passenger demand changes in a disrupted situation. Forecasts of passenger demand traditionally focus on the long-term. Forecasts for disruption management on the contrary requi...

selection of best demand model for explaining of consumer behaviour is one of the most important issues in microeconomic. in this paper we introduce aids[1],cbs[2], nbr[3] and rotterdam model and estimate these models by iranian urban households data for period 1973-2012.seemingly unrelated regression method is chosen for estimation of 5 groups of commodities including food, housing, clothing, ...

in this study the consumption behavior of iranian urban households is analyzed for the eight main food commodities groups including cereal and its products, meat, milk and its products and eggs, fruits and vegetables, edible oils and butter, beverages, grains and nuts over 1974-2007. in this context, the flexible demand models such as quadratic expenditure, rotterdam, almost ideal demand system...

Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal utility maximization problem;...

This study explored the roles of nutrients in the demand for food through utility theory. The findings support the argument that nutrients play important roles in the demand for food. The 1987-88 Nationwide Food Consumption Survey data were used. The impacts of six nutrients (carbohydrates, fats, vitamins, minerals, digestible fibers, and proteins) on the demand for five food groups (dairy, mea...

This paper considers the application of various models of consumer demand to United Kingdom time series from 1900 to 1970. As well as testing the various forms of the "Rotterdam" model, reparametrization of that system is carried out in order to test the linear expenditure system and the direct addilog system on an exactly comparable basis. A further variant of the Rotterdam model is also intro...
