{hi:isco88_to_esec()} {hline 2} Translate 4-digit ISCO-88 to ESeC classes

{title:Syntax}

        {cmd:isco88_to_esec(}{varname} [{help crosswalk##case:{it:case}}]{cmd:)}

{pstd}
    where {it:varname} contains 4-digit ISCO-88 codes
    and {it:case} selects the destination column.

{pstd}
    Typical usage:

        {cmd:isco88_to_esec(}{varname} {cmd:case.esec88(}{it:sempl} {it:supvis}{cmd:)}{cmd:)}

{pstd}
    with {it:sempl} and {it:supvis} as described in {helpb _cwcasefcn_esec88:case.esec88()}.

{title:Description}

{pstd}
    {helpb crosswalk} table translating 4-digit ISCO-88 codes to ESeC classes
    (European Socio-economic Classification; see Harrison/Rose 2006). Note that
    ESeC is defined at the level of minor ISCO groups (3 digit); that is, all
    unit groups within a minor group will translate into the same class.

{pstd}
    Cases (destination columns):

        1 = employment status unknown (simplified ESeC)
        2 = employed, without supervisory status
        3 = employed, with supervisory status
        4 = self-employed, no employees
        5 = self-employed, 1-9 employees
        6 = 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.

    {cmd:isco88_to_esec()} is implemented as a wrapper for 
    {helpb _cwfcn_isco88_to_isco88_3:isco88_to_isco88_3()} followed by
    {helpb _cwfcn_isco88_3_to_esec:isco88_3_to_esec()}.
