Description of instrument: $risk_holtLaury_random
 
This is a holt laury style risk experiment.
Participants are presented with several tickets. They will be paid on just one of them (that will
be randomly chosen after all tickets have been submitted).

Each ticket has two options. For each ticket, the participant choses just one of the options.

If a ticket is chosen, the participant payout is based on which option (on the randomly selected
ticket) he chose.

Each option has a low and a high payout. Which one of these is paid depends on a 2nd random decision.

Thus, a participant will chose the A or B option for several tickets.

The administrator will (randomly) chose which ticket to use, and whether this ticket's
low or high payout will be paid.

Unlike the basic holt laury, each ticket is presented seperately.  The order of values can be
random -- it does not have to "decreasing in riskiness". or follow any other pattern.


General Variables

OPTIONA_LOW          : Low value for option A for all ticket 
OPTIONA_HIGH         : High value for option A (all tickets) 
OPTIONB_LOW          : Low value for option B (all tickets) 
OPTIONB_HIGH         : High value for option B (all tickets) 
SHOWTABLE            : Show a table listing both options payouts (low on one row, high on the other row) 
SHOWCHEAPTALK        : Display an cheap talk explanation of the payouts 
BASEPAYOUT           : The base payout: low and high payouts on tickets are added to this
