CAREER PEAKS IN THE NETHERLANDS FOR LABOUR MARKET ENTRY COHORTS FROM THE 1950s 1960s, 1970s Testing Goldthorpe’s assumption of occupational maturity around age 35
MAARTEN WOLBERS RADBOUD UNIVERSITY NIJMEGEN RUUD LUIJKX TILBURG UNIVERSITY WOUT ULTEE RADBOUD UNIVERSITY NIJMEGEN RC 28 YALE UNIVERSITY NEW HAVEN AUGUST 3-6, 2009
FOUR RC28 GENERATIONS (GANZEBOOM, TREIMAN & ULTEE 1989) FIRST LIPSET TWO-MOMENT DATA PERCENTAGES SECOND DUNCAN THREE-MOMENT DATA PATH MODELS THIRD HAUSER- FOUR-MOMENT DATA GOLDTHORPE LOG-LINEAR MODELS FOURTH MAYER- FULL JOB HISTORIES BLOSSFELD EVENT MODELS THIS PAPER IS A FOURTH GENERATION PAPER
THE IMPORTANT DIFFERENCE BETWEEN GENERATIONS : LATER GENERATIONS SAY OF EARLIER ONES THAT THEIR QUESTIONS POSE THE ISSUE POORLY (DUNCAN) , ARE NOT DETAILED ENOUGH (HAUSER) , NOT SPECIFIED PROPERLY (BLOSSFELD) THE FOURTH GENERATION UNTIL NOW BYPASSED THE QUESTION OF CAREER PEAKS
PRIME DUTCH FOURTH GENERATION STUDY PAUL DE GRAAF 1992 RETROSPECTIVE JOB HISTORIES FOR 427 MEN COLLECTED IN 1982 AVERAGE OCCUPATIONAL STATUS FOR THREE COHORTS AFTER THE NUMBER OF YEARS SINCE LABOUR MARKET ENTRY STATUS RISES DURING A LIFETIME AND IS HIGHER FOR LATER COHORTS
UNDERUSE OF JOB HISTORY DATA FIGURES LIKE THIS BYPASS THE IDEA THAT AN INDIVIDUAL’S CAREER PEAKS
YET THE QUESTION OF THEAGE AT WHICH AN INDIVIDUAL’S CAREER PEAKS HAS SOME PERTINENCE ACCORDING TO GOLDTHORPE (1981: 51-52) THE CAREERS OF MOST INDIVIDUALS HAVE MATURED AROUND AGE 35 THE OCCUPATIONAL MATURITY ASSUMPTION ALLOWS FOR ANSWERING QUESTIONS ABOUT TRENDS WITH DATA FROM ONE SURVEY ONLY
THE QUESTION : HAS THE AGE AT WHICH A PERSON’S CAREER PEAKS SHIFTED UP OR DOWN WITH EACH NEW LABOUR MARKET ENTRY COHORT ? IS A SECOND GENERATION QUESTION
IT SHOULD BE REPLACED BY THE FOURTH GENERATION QUESTION : AFTER OVERVIEWING A PERSON’S JOB HISTORY AND DETERMINING THIS PERSON’S PEAK, ARE THE ODDS FOR THIS PERSON TO HAVE MOVED IN A CERTAIN PERIOD FROM NON-PEAK TO PEAK HIGHER , THE SAME , OR LOWER IF THIS PERSON BELONGS TO A LATER LABOUR MARKET ENTRY COHORT ?
THE GOLDTHORPE HYPOTHESIS : THE EFFECTS OF FACTORS LIKE FATHER’S OCCUPATIONAL STATUS , EDUCATION , STATUS FIRST OCCUPATION AND NATIONAL UNEMPLOYMENT RATE ON THE AGE AT WHICH MEN REACH THEIR PEAK HAVE MORE OR LESS RUN OUT BEFORE AGE 35
THIS PAPER’S ALTERNATIVE HYPOTHESIS : THE EFFECTS OF THE FACTORS AGE (MONTHS ON THE LABOUR MARKET) EDUCATION AND NATIONAL UNEMPLOYMENT RATE ON MOVING DURING SOME FIXED PERIOD FROM NON-PEAK TO PEAK IMPLY HIGHER ODDS OF PEAKING AFTER AGE 35
MORE IF THIS PAPER’S HYPOTHESES : PERSONS DURING A FIXED PERIOD ARE MORE LIKELY TO SHIFT TO THEIR PEAK IF THE UNEMPLOYMENT RATE IN THAT PERIOD WAS LOWER IF THAT PERSON IS OLDER (HAS BEEN LONGER ON THE LABOUR MARKET) IF THAT PERSON HAS MORE EDUCATION IF THAT PERSON’S FATHER HAD A HIGHER STATUS IF THAT PERSON’S FIRST JOB HAD A HIGHER STATUS
THIS PAPER’S DATA SERIES OF FAMILY SURVEY DUTCH POPULATION WITH NEW SAMPLES FOR 1993 1998 2000 2003 TO BE ADDED 2009 PLUS HIN 2005 RETROSPECTIVE JOB HISTORIES FOR MEN AND WOMEN AGED 18-70
HERE SELECTED : ALL MEN AT LEAST AGED 45 AT TIME OF INTERVIEW WOMEN DESERVE SEPARATE TREATMENT IT WOULD BE UNWISE AND UNNECESSARY TO SELECT ONLY MEN WHO HAVE DEFINITIVELY RETIRED FROM THE LABOUR MARKET
THE CLASSICAL GRAPH FOR THE PRESENT DUTCH DATA SET : FOR LATER COHORTS, AVERAGE ENTRY OCCUPATIONAL STATUS , MEASURED AS ISEI RANGING FROM 10 TO 90 , RISES BUT PEAKS EARLIER WITH INCREASING NUMBER OF MONTHS ON THE LABOUR MARKET
ANOTHER CLASSICAL GRAPH AVERAGE OCCUPATIONAL STATUS INCREASES MOST FOR MEN WITH SECONDARY EDUCATION, AND LEAST FOR MEN WITH TERTIARY EDUCATION
DETERMINE FOR EACH MAN HIS CAREER PEAK NOW MAKE A MEN-MONTHS FILE DETERMINE WHETHER A MAN AT THE BEGINNING OF A MONTH IS AT THE PEAK OF HIS CAREER IF YES, DELETE THESE CASES IF NO, DETERMINE WHETHER THIS MAN AT THE END OF A MONTH IS AT HIS PEAK TAKE AGE OF THE MAN OR THE NUMBER OF MONTHS SINCE LABOUR MARKET ENTRY AS A TIME-DEPENDENT COVARIATE
MEAN PEAK AGE FOR EACH COHORT : 1950s COHORT 34.8 1960s COHORT 34.0 1970s COHORT 32.5
PERTINENT GRAPH 50% OF THE 1950s COHORT MEN IS AT THEIR PEAK WITHIN 90 MONTHS 50% OF THE 1960s COHORT MEN IS AT THEIR PEAK WITHIN 60 MONTHS 50% OF THE 1970s COHORT MEN IS AT THEIR PEAK WITHIN 30 MONTHS
OF THE MEN IN THE 1970s COHORT, AFTER 300 MONTHS ABOUT 40% PERCENT IS NOT AT THEIR PEAK THIS MEANS THAT QUESTIONS ON MAKING THE PEAK SHOULD BE COMPLEMENTED WITH QUESTIONS ON SLIDING FROM THE PEAK GOLDTHORPE’S MATURATION NOTION : MATURATION NOT ONLY AS STAYING AT A PEAK BUT ALSO AS BELOW EARLY PEAK STABILIZATION ?
MEAK PEAK AGE FOR SIX LEVELS OF EDUCATION : PRIMARY 34.5 LOWER SECUNDARY 33.9 INTERMEDIATE SECUNDARY 33.8 HIGHER SECUNDARY 32.6 LOWER TERTIARY 34.7 HIGHER TERTIARY 34.3
ANOTHER PERTINENT GRAPH OF MEN WITH PR + LS EDUCATION, 50% AT PEAK WITHIN 50 MONTHS OF MEN WITH IS + HS EDUCATION, 50% AT PEAK WITHIN 50 MONTHS OF MEN WITH TERTIARY EDUCATION, 50% AT PEAK WITHIN 100 MONTHS
