The sample selection model is based upon a bivariate or a multivariate structure, and distributional assumptions are in this context more severe than in univariate settings, due to the limited availability of tractable multivariate distributions. While the standard FIML estimation of the...

Global biodiversity loss and its consequences for human welfare and sustainable development have become major concerns. Economists have, therefore, given increasing attention to the policy issues involved in the management of genetic resources. To do so, they often apply empirical methods...

This paper investigates whether a nation’s contingent value of hosting a mega-event depends on past experience with implied public goods benefits for its residents. Applying data from an ex-ante and ex-post query based on contingent valuation methods, we use the FIFA World Cup 2006 as a...

Stated preference methods using surveys to elicit willingness to pay have been shown to suffer from hypothetical bias and scope/scale bias. Hypothetical bias usually means that willingness to pay is exaggerated in the hypothetical scenario and scope/scale bias means that there is an...

This study investigates whether or not the scale bias found in contingent valuation (CVM) studies on mortality risk reductions is a result of cognitive restraints among respondents. Scale bias refers to insensitivity and non near-proportionality of the respondents' willingness to pay (WTP) to...

Abstract: Public investments are dynamic in nature, and decision making must account for the uncertainty, irreversibility and potential for future learning. In this paper we adapt the theory for investment under uncertainty for a public referendum setting and perform the first empirical test to...

We propose estimators of features of the distribution of an unobserved random variable W. What is observed is a sample of Y; V; X where a binary Y equals one when W exceeds a threshold V determined by experimental design, and X are covariates. Potential applications include bioassay and...

Forest provides a wide range of environmental goods and services among which, biodiversity or consumption goods: they are know as forest amenities and constitute public goods. So, the valuing of forest cannot be directly based on market prices but is estimated using revealed preference methods....

The contingent valuation (CV) method is an attractive approach for comparing home care to hospital care in which the only difference is patients’ well-being during the treatment process and not health outcomes. We considered the empirical situation of blood transfusion (BT) in cancer patients...

In this paper we aim to look into the attributes of Ghanaians’ willingness-to-pay for green products. This would help us to assess whether Ghanaians show a preference towards environmental goods. The methodology employed to address these issues is an ‘experimentally-adapted’ CV survey...
