Use of TANF Work-Oriented Sanctions in Illinois, New Jersey, and South Carolina. Appendix A: Methodology for Multivariate Analysis

04/30/2004

To examine the affect of individual characteristics on being sanctioned in each of the three study states in a multivariate context, we use a series of logit models to estimate whether specific characteristics affects whether a TANF case head is sanctioned. The analysis is based on the single-parent TANF cases from each state who had no missing data on sanction status and the selected characteristics for study.(8) A list of variables included in the models and their means and standard deviations for each state are presented in Table A.1. The logit estimation results for the states are presented in Tables A.2, A.3, and A.4.

We estimate equation (1) to determine how each individual characteristic affects sanction status. This equation expresses sanction status as a function of select characteristics including gender, age, educational level, race/ethnicity, marital status, number of children on the TANF case, age of the youngest child on the TANF case, duration of the current TANF spell, and current earnings as represented in a series of 22 dummy variables.

(1) SancStati = 0 + jLji + k + i
where:

  • SancStati = 1 if sanctioned; 0 otherwise
    Lji = 1 if specific characteristic j is present; 0 otherwise; j = 1,, 22
    Apa_letteru.gifi = random disturbance term
    Apa_lettera.gif0, Apa_lettera.gifj, Apa_theta.gifk = parameters to be estimated
    i = index for study population, i = 1,, 33,478(IL); 51,545(NJ); 10,852(SC)

The variable SancStat represents different sanction status' throughout the models. For Illinois--results presented in Table A.2--we examine being partially sanctioned within 12 months (Model 1) and being fully sanctioned within 12 months (Model 2). We do the same for New Jersey, with results for partial sanction within 12 months (Model 3) and full sanction within 12 months (Model 4) presented in Table A.3. Due to more recent study month selected for South Carolina, we have fewer follow-up months for study. For this reason, we examine we examine being fully sanctioned within 10 months in South Carolina. Results of this model (Model 5) are presented in Table A.4.

We then turn to the use of survey data from Illinois to estimate whether more specific personal liabilities or the number of such liabilities affects whether a TANF case head is sanctioned (partially or fully) within 12 months. The analysis sample includes the 375 survey respondents who had no missing data on sanction status, selected background characteristics, or any of the 15 personal liability measures. A list of variables included in these models and their means and standard deviations are presented in Table A.5. The logit estimation results are presented in Tables A.6 and A.7.

First, we estimate equation (2) to determine how each individual personal liability affects sanction status. This equation expresses sanction status as a function of 15 personal liabilities, and the same set of background characteristics as in equation (1).

(2) ASANC12i = 0 + jLji + kXki + i
where:

  • ASANC12i = 1 if sanctioned (partially or fully) within 12 months; 0 otherwise
    Lji = 1 if specific liability j is present; 0 otherwise; j = 1,, 16
    Xki = set of background control variables, k = 1,, K
    i = random disturbance term
    0, j, k = parameters to be estimated
    i = index for survey respondents, i = 1,, 375

Next, we estimate equations (3) and (4) to determine whether the number of personal liabilities affects sanction status. These equations express sanction status as a function of the number of employment liabilities and a set of background characteristics. We specify the number of barriers as a series of seven dummy variables in equation (3) and as a series of three dummy variables in equation (4).

(3) ASANC12i = 0 + jN1ji + kXki + i
where:

  • ASANC12i = 1 if sanctioned (partially or fully) within 12 months; 0 otherwise
    N1ji = 1 if the number of personal liabilities is j; 0 otherwise; j = 1,, 6
    N17i = 1 if the number of personal liabilities is 7 or more; 0 otherwise
    Xki = set of background control variables,(9) k = 1,, K
    i = random disturbance term
    0, j, k = parameters to be estimated
    i =index for survey respondents, i = 1,, 375

(4) ASANC12i = 0 + jN2ji + kXki + i
where:

  • ASANC12i = 1 if sanctioned (partially or fully) within 12 months; 0 otherwise
    N21i = 1 if the number of personal liabilities is j; 0 otherwise; j = 1,, 6
    N22i = 1 if the number of personal liabilities is 7 or more; 0 otherwise
    Xki = set of background control variables, k = 1,, K
    i = random disturbance term
    0, j, k = parameters to be estimated
    i =index for survey respondents, i = 1,, 375
