We develop a model of household demand for frequently purchased consumer goods that are branded, storable and subject to stochastic price fluctuations. Our framework accounts for how inventories and expectations of future prices affect current period purchase decisions. We estimate our model using scanner data for the ketchup category. Our results indicate that price expectations and the nature...

There is growing interest in transportation pricing reforms to help achieve various planning objectives such as congestion, accident and emission reductions. Their effectiveness is affected by the price sensitivity of transport, that is, the degree that prices affect travel activity, measured as elasticities (percentage change in travel caused by a one-percent price change). Lower elasticities ...

This paper challenges the growing consensus in the literature (Stone, 2005; Dodds, 2007) that medieval English peasants and manorial managers were price responsive in their production decisions. Using prices of and acreages planted with wheat, barley, and oats on 49 manors held by the bishop of Winchester from 1349-70, we estimate price elasticities of supply for each grain in aggregate and on ...

This paper summarizes price elasticities and cross elasticities for use in public transit planning. It describes how elasticities are used, and summarizes previous research on transit elasticities. Commonly used transit elasticity values are largely based on studies of shortand medium-run impacts performed decades ago when real incomes where lower and a larger portion of the population was tran...

Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate shrimp data differentiated by source country. Own-price elasticities for all countries had the expected negative signs, were statistically significant, and inelastic. The scale elasticities for all countries were positive and statistically significant at the 1% level with only the United States and Ec...

The objective of this article is to estimate the own-price, cross-price and income elasticities of demand for SSB in Ecuador, as an indispensable step for predicting a reduction in the consumption of said beverages caused by the potential implementation of taxes in Ecuador. In addition, the own-price, cross-price and income elasticities of sugar-free substitutes like mineral water and diet soft...

This study estimates a set of unconditional own-price and expenditure elasticities across time for 49 processed food categories using scanner data and the FAST multistage demand system with fixed effects across time. Estimated own-price elasticities are generally much larger, in absolute terms, than previous estimates, while our expenditure elasticities are generally much lower. The use of disa...

Using the most recently available data, this paper estimates the price and income elasticities of gasoline demand in the United States from a semiparametric smooth coefficient model. The econometric approach provides more flexibility by allowing functional coefficients to accommodate heterogeneity in gasoline demand. Instrumental variables are used to correct for the potential endogeneity of th...

water markets are instrumental in efficient allocation and pricing of scarce water by enhancing allocative and price efficiency of water use. the prerequisites for water market formation are tradable water rights independent from ownership of the land, extensive water canals, water use associations, and adequate market regulations. mojen water market has been facilitating exchange of alternativ...
