This study examines the substitution effect between fixed-line and mobile telephony while controlling for the consumption externality associated with telephone networks. A dynamic demand model is estimated using a global telecommunications panel dataset comprised of 56 countries from 1995–2000. Estimation results show the presence of a substantial substitution effect. Additionally income and ow...

We estimate the price elasticity of water demand with household-level data, structurally modeling the piecewise-linear budget constraints imposed by increasing block pricing. We develop a mathematical expression for the unconditional price elasticity of demand under increasing block prices and compare conditional and unconditional elasticities analytically and empirically. We test the hypothesi...

The food demand in India has been examined in the context of a structural shift in the dietary pattern of its population. The results have reinforced the hypothesis of a significant diversification in the dietary pattern of households in recent years and has found stark differences in the consumption pattern across different income quartiles. The food demand behaviour has been explained using a...

BACKGROUND Chile is the second world's largest per capita consumer of caloric beverages. Caloric beverages are associated with overweight, obesity and other chronic diseases. The objective of this study is to estimate the price elasticity of demand for soft drinks, other sugar-sweetened beverages and high-energy dense foods in urban areas in Chile in order to evaluate the potential response of ...

South Africa faces a severe and growing obesity epidemic. Obesity and its co-morbidities raise public and private expenditures on healthcare. Sugary beverages are heavily consumed in South Africa and are linked to the onset of overweight and obesity. Excise taxation of sugary beverages has been proposed and adopted in other settings as a means to reduce harms from their consumption. A tax on th...

We test the Becker-Murphy model of rational addiction with New Zealand credit card debt data. Our results clearly favour the rational addiction model over the myopic, backward-looking model. The estimated short-run and long-run price elasticities are-0.58 and-2.32 respectively, and the estimated rate of time-preference is 6.7% per quarter.

We empirically estimate the substitutability of fixed and mobile services for telecommunications access using a large, U.S. household survey conducted over the period 1999-2001. We find significant positive cross-price elasticities between mobile and wireline usage. Because mobile usage prices fell dramatically over this period, we estimate that wireline usage may have been about 50% higher had...

The model in Verboven (2002) is extended to include non-zero price elasticities and behavior in the fuel market is modelled explicitly. With the use of simulations it is shown, that this makes quite a difference and, therefore, might lead to bias in parameter estimates
