Subjects were each seated at a computer and responded individually to questions that appeared on the screen. The computers presented pairs of items in a unique random order for each subject. The goods had short names that appeared side-by-side on the monitor, with their position (right versus left) also randomized. The respondent entered a choice by pressing the right or left arrow key and could correct mistakes by pressing "backspace." At the end of the 155 paired comparisons, the computer code repeated in random order those pairs that were not consistent with the individual's dominant preference order. It also randomly selected ten consistent pairs. The individual pairs in these two sets of repeated choices were randomly intermixed, and there was nothing to indicate to the respondent when the 155 original pairs ended and the repeats began. The computer program recorded the respondent's choice for each pair, the time in seconds required for each choice, and the sequence number of each choice. The pairs were made up of 21 items (10 goods and 11 sums of money). The 155 pairs consisted of all 45 pairs comparing the goods plus 110 pairs comparing a good with a sum of money. Subjects were first given a list of the 10 goods. This list was as follows: Goods included in the experiment ________________________________________________________________________ PRIVATE GOODS 1.

Please read all of the instructions and follow them carefully when answering questions. PLEASE NOTE: After entering an answer, you can backspace to correct a mistake or change a selection, if needed. PLEASE WAIT FOR FURTHER INSTRUCTION ON HOW TO BEGIN. ### Please compare the following pairs of goods. Use the right or left arrow key to indicate which of these goods you prefer. ________________________________________________________________________ Socioeconomic and debriefing questions followed the choices between pairs of items.
