1 The data for Section 4, on risk

1.1 Codebook for risk

Each case (= participant) consists of three lines. The four entries on each first line indicate the following:
  1. Participant's number;
  2. Economics student? (Yes/No);
  3. Age;
  4. Gender (Male/Female).
The six numbers on each second line indicate the following:
  1. The first measurement of x1;
  2. The second measurement of x1;
  3. The resulting average measurement of x1;
  4. The first measurement of x2;
  5. The second measurement of x2;
  6. The resulting average measurement of x2.
Finally, the five numbers on each third line indicate the following:
  1. The first measurement of w-1(1/8);
  2. The second measurement of w-1(1/4);
  3. The resulting average measurement of w-1(1/2);
  4. The first measurement of w-1(3/4);
  5. The second measurement of w-1(7/8).
