  4. 4. Aim Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin <ul><li>analysis of significance of different attributes regarding agricultural skilled employee and agricultural managers </li></ul><ul><li>for example: How important is work experience and what level is the best? </li></ul><ul><li>more attributes: academic degree, vocational education, different levels of soft skills etc. </li></ul><ul><li>view of employers in agricultural production </li></ul><ul><li>comparison with views of experts from educational institutions </li></ul><ul><li>furthermore: requirements concerning managers from the focus of entrepreneurship </li></ul>
  5. 5.

  6. 6. Method (2) Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin <ul><li>theoretical background: random utility theory </li></ul><ul><li>modelling of choice decision with multinominal logit model </li></ul><ul><li>estimation of utility with maximum likelihood estimation (OLS not possible) </li></ul>
  7. 7. Significance Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin <ul><li>situation: </li></ul><ul><ul><li>rising requirements regarding agricultural labour (professionalisation + specialisation) </li></ul></ul><ul><ul><li>improvement of educational quality of labour force </li></ul></ul><ul><li>necessary: fitting educational programs </li></ul><ul><li>education = crucial future and cost factor for farms </li></ul><ul><li>results may influence educational institutions (vocational school, universities etc.) </li></ul>

  9. 9. Problems Ph.D. workshop 2009, 05.10.2009 – 09.10.2009, Berlin <ul><li>How to sum up similar studies from the past to derive the time development of requirements from the results? </li></ul><ul><ul><li>Studies too heterogeneous and rare to use meta- or best-evidence-analysis </li></ul></ul><ul><ul><li>narrative solution possible, but somewhat “unscientific” </li></ul></ul><ul><li>more problems likely to follow </li></ul>
