Dealing with bottled water expenditures data with zero observations: a semiparametric specification
نویسندگان
چکیده
This paper analyzes bottled water expenditures data with zero observations by employing parametric and semiparametric models. The overall results of specification tests indicate that the semiparametric model outperforms the parametric model significantly. 2000 Elsevier Science S.A. All rights reserved.

Reports of Water Quality Violations induce Consumers to buy Bottled Water
The 1996 Safe Drinking Water Act Amendments require that water utilities send quality reports to customers. We test whether receiving WQRs of health violations increases purchases of bottled water. With new data, we find a larger response than previous studies, and, unlike previous studies, we disaggregate the intensive and extensive margins of demand changes. We find a water quality violation ...
متن کاملRisk perceptions of arsenic in tap water and consumption 3 of bottled water
6 [1] The demand for bottled water has increased rapidly over the past decade, but bottled 7 water is extremely costly compared to tap water. The convenience of bottled water 8 surely matters to consumers, but are others factors at work? This manuscript examines 9 whether purchases of bottled water are associated with the perceived risk of tap water. All 10 of the past studies on bottled water ...
متن کاملSemiparametric location estimation under non-random sampling.
We study a class of semiparametric skewed distributions arising when the sample selection process produces non-randomly sampled observations. Based on semiparametric theory and taking into account the symmetric nature of the population distribution, we propose both consistent estimators, i.e. robust to model mis-specification, and efficient estimators, i.e. reaching the minimum possible estimat...

متن کاملSemiparametric Hierarchical Bayes Analysis of Discrete Panel Data with State Dependence and Serial Correlation
In this paper we consider the analysis of semiparametric models for binary panel data with state dependence and serial correlation. A hierarchical approach is used in addressing heterogeneity, dealing with the initial conditions, and incorporating correlation between the covariates and the random effects. We consider a semiparametric specification in which a Markov process smoothness prior is u...
