Ans: 1. Hypothetical Choices- relied on participant responses; decision had no weight on it
2. Laboratory experiments

-problems: 1) often times participants were undergrad students 2) usually made real choices
involving real money or goods (usually very small amount); however, preferred over
hypothetical scenarios
3. Field experiments
-observe everyday behavior of individuals (typically) unaware that they are participating in a
