Abstract:
We report results from an eye-tracking experiment designed to study a violation of revealed preference predicted by salience theory: Individuals choose a low quality good with a low price level and a high quality good with a high price level, despite the price of the quality premium being held constant. Subjects exhibited a significant number of such preference reversals (16.12% of decisions). However, the eye-tracking hypotheses, which test the underlying mechanism of salience theory are all rejected. More reversals were observed with hypothetical than incentivized choice (22.11% vs. 10.12% of decisions). Attending to the price of a good was found to bias subjects in favour of purchasing it.
