In the previous section, we presented the results from cross-tabulations of fixed-term employees by other socio-economic factors based on the European Labour Force Survey 1983-96. The goal of this section is to test the hypotheses developed in Chapter 2 using multivariate analyses on data from 1988 to 1991. Since results proved very stable we report only estimates from 1991; other results can be obtained from the authors on request. The phenomenon in question is: who is likely to hold a job without specification of the date of expiration, i.e. a 'standard' work contract? Obviously, the opposite value determines the probability of holding a fixed-term contract.
