Survey data from cotton farmers in six southeastern states of the USA were used to estimate the demand and willingness-to-pay (WTP) for either retrofitting yield monitors onto cotton pickers or to purchase a yield monitor as an option with a new cotton picker. ‘Don’t know’ responses were either omitted, combined with ‘no’ responses or included as a separate category for comparing WTP and estimates of the price elasticity of demand. Our results suggest that treating the ‘don’t know’ response as a separate category provides WTP estimates that are more consistent with expectations than the other approaches. The estimated price elasticities and demand curves indicate that previous users of precision technology are more responsive to changes in price of cotton yield monitors and would be more likely to adopt them when the price decreases. These demand and WTP estimates provide important information that can be used by those who sell cotton yield monitors, as well as policy-makers who may wish to subsidize this technology. Referendum contingent valuation was useful for evaluating the demand for any new technology.
