Seven Challenges to Designing Effective Experiments for Use in the Field
Overview
Challenge One: There Are Social and Ethical Concerns Associated with Asking Poor People to Gamble for Food or Money
Challenge Two: There Are Practical Concerns Involving Choice of Reward Currencies, Expressions of Probability, and Paying Out Delayed Rewards
Challenge Three: Experiments with Hypothetical Rewards May Generate Hypothetical Responses
Challenge Four: Complicated Experimental Designs Are Difficult to Explain to Research Subjects
Challenge Five: Low Variability in Responses May Limit Analyses
Challenge Six: Absence of Evidence for an Effect Is Not Evidence for Absence of an Effect
Challenge Seven: Inconsistent Results Are Difficult to Interpret
Consistency in Numerical Estimates of Preferences
Consistency in Determinants of Preferences
