In the current paper, we compare alternative approaches to incorporating uncertainty into the statistical analysis of dichotomous choice responses. In doing so, first we employ previous modelling techniques that included uncertainty of preferences, and secondly we compare the obtained results...

Dichotomous choice willingness to pay questions are often used to determine the value visitors place on nature-based recreation. Ambiguity in wording can result in the use of information that does not necessarily reflect visitors’ true WTP. For example, depending on the specificity of the...

We update the joint estimation of revealed and stated preference data of previously published research to allow for joint estimation of the Travel Cost Method (TCM) portion using count data models. The TCM estimation also corrects for truncation and endogenous stratification as well as...

Almost all applications of the Travel-Cost-Method demand function which include site quality variable(s) are multisite models. The results of this study serve as a note of warning that using the demand equation derived from multisite cross-sectional data to perform a benefit-cost analysis of...

The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small...

This study examines the relative price of a standard market basket of food items and a market basket of healthier alternatives. Because people in low-income neighborhoods may have fewer grocery stores and transportation alternatives, the effects of store size and competition on the price of a...

The impacts of market reforms on prices volatility in developing countries are not well understood because analysts have not been able to predict the impacts. This study investigates whether the reforms have exacerbated the degree of spatial volatility of maize price in Tanzania using ARCH-M...

A censored demand system estimator is proposed by extending the sample selection model of Heckman. Censoring is governed by a selection mechanism which avoids the restricitve Tobit parameterization. Results of application to household consumption of beverages suggest the estimator produces...
