{hi:isco08_3_to_esec()} {hline 2} Translate 3-digit ISCO-08 to ESeC classes

{title:Syntax}

        {cmd:isco08_3_to_esec(}{varname} [{help crosswalk##case:{it:case}}]{cmd:)}

{pstd}
    where {it:varname} contains 3-digit ISCO-08 codes
    and {it:case} selects the destination column.

{pstd}
    Typical usage:

        {cmd:isco08_3_to_esec(}{varname} {cmd:case.esec(}{it:sempl} {it:supvis}{cmd:)}{cmd:)}

{pstd}
    with {it:sempl} and {it:supvis} as described in {helpb _cwcasefcn_esec:case.esec()}.

{title:Description}

{pstd}
    {helpb crosswalk} table translating 3-digit ISCO-08 codes to ESeC classes
    (European Socio-economic Classification; see Harrison/Rose 2006).

{pstd}
    Cases (destination columns):

            1 = employed, without supervisory status
            2 = employed, with supervisory status
            3 = self-employed, no employees
            4 = self-employed, 1-9 employees
            5 = self-employed, 10 or more employees

{pstd}
    Employees with supervisory status are employees who have formal responsibility
    for supervising the work of other employees. If the data does not contain a
    direct measure of supervisory status, Harrison and Rose (2006, section 4.7)
    suggest coding employees as supervisors if they are supervising at least
    three people.

    960, 961, and 962 are missing in the ESeC list provided in
    {bf:esec_08_3_digit_public.xlsx}; {cmd:isco08_3_to_esec()} applies the same
    ESeC classes as for minor groups 950, 951, and 952.
