Preferences,beliefs, and values in negotiations concerning aid to Nicaragua

The paper argues that in the context of public choice for non-market goods, two assumptions of the simple model of the rational economic actor may not hold. The assumptions are that there is a direct connection between choice and outcome, and that preferences are not affected by the act of making a choice. Consequently, to understand people's preferences for public goods, it is important to measure their beliefs and values separately rather than simply to observe their choice behavior or to ask them what they would be willing to pay for the public good. In an example study, people's preferences for U.S. policies toward Nicaragua were measured and further analyzed into their beliefs about the effects of those policies on Nicaraguan outcomes, and their evaluations of the Nicaraguan outcomes. It was shown that the process of making a two-person choice changed the preferences, and that the separate measures or beliefs and values gave insight into the process of the change that would not have been available had only the preferences been measured. Implications for the contingent valuation method are explored and an alternative approach is proposed.
