serial: unique ID for each participant
republican1: -1 = democrat, 0 = other, 1 = republican
offset1: 1 = offset frame, -1 = tax frame
integrate1: 1 = price integration frame, -1 = price segregation frame
interaction: offset1*integrate1. Used for regressions and such.
envirofirst1: if the carbon tax/offset option was presented first (ie, on the left), 1. Otherwise, -1.

Note: Product 1 = gas, 2 = flight, 3 = electricity, 4 = computer. However, IN STUDY 2 THE NUMBERS ARE DIFFERENT! Specifically, in study 2 flight was first and gas was second. 

co1 = chose offset/tax on the first product (gas). 1 = chose the tax/offset option. 
ps1	= preference strength for the first product (gas). Higher numbers = greater preference for the tax/offset option. 
mm1	= support for making the carbon tax/offset mandatory, for the first product (gas). Higher numbers indicate more support for regulation. 
cr1	= Estimate of consumption reduction (in %) if the tax/offset is made mandatory, for product 1 (gas). 
co2	= chose offset/tax on the second product (flight). etc...

experiment_number = wave number (from referrer) that the participant was run in. The present study was run with 3 other studies. 
path = the order that the participant completed the study in. It's fully counterbalanced, which is kind of ridiculous. 
begin_time = date and time that participant began the study (including the other, unrelated parts of the wave, which occured before and/or after)
end_time = date and time that participant ended the study	
duration_minutes = total time for participant to complete the study (including the other, unrelated parts of the wave, which occured before and/or after)
