Abstract
This experiment attempts to test whether approximations of the indirect utility functions are indeed the same as the indirect utility function implied by the optimized goods -- how we value money prior to deciding what to purchase.

Interventions

Intervention(s)
The intervention focuses on how people react to goods and their willingness to exert effort to obtain these items.

Primary Outcomes

Primary Outcomes (end points)
How many sliders are completed (output or effort), how long the subjects chose to work, how much credit was earned
Primary Outcomes (explanation)
The credit earned is according to a payment scale fully known to the subjects prior to exerting effort.

Secondary Outcomes

Secondary Outcomes (end points)
The prices of the goods selected, other properties of goods selected (category / type, weight, size)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
This experiment investigates how people value goods and shopping credit.
Experimental Design Details
In this experiment, I investigate whether individuals are willing to exert more or less effort after selecting the goods they wish to purchase. The treated subjects select their own goods among hundreds of thousands on pchome.com.tw, and then may exert effort to earn these items. The control subjects instead first learn how effort translates to PCHome.com credit, may then exert effort, and lastly may select the goods. It's important to note that subjects are allowed to browse PCHome.com at any time they wish.
Randomization Method
Done in office by a computer (javascript code for random number generation)
Randomization Unit
at the individual subject level
Was the treatment clustered?
No
