The data are in the DOS-format file romeo.data, which is zipped in
romeo.zip.

Data arrangement: The data are arranged in a 452x15 matrix.  Each row of the
matrix represents a data record.  There are 15 variables in each record, and
452 records in the data set.

Dataset size = 35KB (in DOS format)

                  Variable definitions by column.

1. Duration of first spell of unemployment, t, in weeks.  

2. Heaping variable, h(t): h(t) = 1  if  t = 2,4,6,8 
                     h(t) = 2  if  t = 12,16,22,26,30,35,39,43
                     h(t) = 3  if  t = 48
                     h(t) = 10 if t = 52
                     h(t) = 0 otherwise.

3. Spell = 1 if spell is complete.

4. RACE = 1 if white.

5. SEX = 1 if female.

Reason for unemployment is separated into three dummy variables:

6. JLOSE = 1 if individual is a job loser who is on layoff, or is a job
loser for any other reason;

7. JLEAVE = 1 if individual is a job leaver;

8. REENTR = 1 if individual is a labor force reentrant;

All these dummy variables equal 0 if the individual is a new entrant to the
labor force.  
 
Search methods: In the CCO there are 9 possible active search methods. 
Individuals who are not working and not on layoff, have to be using at least
one of these methods to search for work to be classified as looking
unemployed.  Using these data, we create a search variable as follows:

9. SEARCH = 1 if (1) the unemployment spell is completed between the first and
second surveys and number of methods used to search > average number of
methods used across all records in the sample, or, (2) for individuals who
remain unemployed for consecutive surveys, if the number of methods used is
strictly nondecreasing at all survey points, and is strictly increasing at
least at one survey point.  

10. PUBEMP = 1 if an individual used a public employment agency to search
for work at any survey points relating to the individuals first unemployment
spell.

11-14. FTPT(s) = 1 if an individual is searching for full time work at
survey s, s = 1,2,3,4.

15.NOBS = number of observations on the first spell of unemployment for the
record, NOBS = 1,2,3,4.
