Abstract:
This thesis is concerned with examining issues of theoretical validity and bias in contingent valuation (CV) and discrete choice experiment (DCE) methods in low income countries. This thesis contributes to the small body of literature on the application of CV and DCEs in low income countries and in populations which have little or no formal education. Theoretical validity is examined by testing whether willingness to pay corresponds to theoretical expectations focusing on gender and willingness to pay, sensitivity to scope, starting point bias, and strategic bias in CV. The theoretical validity of the DCE method in populations with no formal education is also explored. It is found that whilst iterative methods to elicit willingness to pay often mimic local market conditions in low income countries they are prone to starting point bias and strategic bias. An association between gender and willingness to pay was also found. Issues of gender, starting point bias and strategic behaviour can be tested for and controlled for in the estimation of willingness to pay and do not present an insurmountable problem. Willingness to pay was also found to be insensitive to the size of the benefit in CV. Using the DCE method, it was found that with the use of visual aids, DCEs can be used among respondents with no formal education. It is concluded that CV and DCEs are feasible and valid in populations with low levels of education when surveys are conducted using trained enumerators and administered using face-to-face interviews. This suggests that both techniques are capable of being used in wide variety of settings. The exception to this is a lack of evidence on sensitivity to scope. Further research is therefore required into sensitivity to scope. Further research is also required to examine the association between gender and willingness to pay.
