There are three data files corresponding to the three household types
in Sections 6 and 7 of the paper. All three files are tab-delimited
text files in DOS format. They are zipped in the file cs-data.zip.
Unix/Linux users should use "unzip -a".

Single_Members.txt (124KB) contains 2218 observations;
Married_Couples_without_Children.txt (187KB) contains 3326
observations; and Married_Couples_with_One_Child.txt (344KB) contains
6141 observations. 

There are eight columns in each data file, and the variable name for
each column (in order) in all files is:

  year = year; 
     y = total expenditure;
    s1 = budget share of gasoline; 
    s2 = budget share of local transportation; 
    s3 = budget share of inter-city transportation; 
    p1 = price of gasoline; 
    p2 = price of public transportation; 
    p3 = price of inter-city transportation.
