households living <strong>on</strong> welfare would (relatively) be especially resp<strong>on</strong>sive towards out-<str<strong>on</strong>g>of</str<strong>on</strong>g>store<br />

promoti<strong>on</strong>s. But, this counterintuitive finding can be caused by a decrease in the<br />

number <str<strong>on</strong>g>of</str<strong>on</strong>g> observati<strong>on</strong>s when distinguishing between in-store and out-<str<strong>on</strong>g>of</str<strong>on</strong>g>-store promoti<strong>on</strong>s,<br />

especially with respect to the outcome <str<strong>on</strong>g>of</str<strong>on</strong>g> the out-<str<strong>on</strong>g>of</str<strong>on</strong>g>-store related promoti<strong>on</strong> resp<strong>on</strong>se.<br />

An additi<strong>on</strong>al interesting finding is that school going shopping resp<strong>on</strong>sible<br />

pers<strong>on</strong>s (students) turn out to be n<strong>on</strong>-resp<strong>on</strong>sive to sales promoti<strong>on</strong>s. In general, students<br />

have a limited budget and are not really time-pressed. Based <strong>on</strong> ec<strong>on</strong>omic theory, <strong>on</strong>e<br />

would expect them to be promoti<strong>on</strong> resp<strong>on</strong>sive. But as Table 7.11 and Table 7.12 show,<br />

students have the lowest estimated coefficient for promoti<strong>on</strong> resp<strong>on</strong>se. Perhaps students<br />

expect to earn relatively a lot in a few years, and they therefore are not really focused <strong>on</strong><br />

saving m<strong>on</strong>ey.<br />

The sec<strong>on</strong>d variable associated with employment situati<strong>on</strong> incorporated in this<br />

research is the job sector <str<strong>on</strong>g>of</str<strong>on</strong>g> the breadwinner. No hypotheses were derived about the<br />

relati<strong>on</strong>ship between this variable and promoti<strong>on</strong> resp<strong>on</strong>se, as we believe that the<br />

employment situati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the shopping resp<strong>on</strong>sible pers<strong>on</strong> is a more important driver <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

promoti<strong>on</strong> resp<strong>on</strong>se. The results show that a household in which the breadwinner has a<br />

relatively ‘high’ job, that promoti<strong>on</strong> resp<strong>on</strong>se is lower, especially due to lower resp<strong>on</strong>se for<br />

in-store promoti<strong>on</strong>s. The rest <str<strong>on</strong>g>of</str<strong>on</strong>g> the findings are n<strong>on</strong>-significant for this variable.<br />

7.5.2.7 Presence <str<strong>on</strong>g>of</str<strong>on</strong>g> N<strong>on</strong>-school Age Children<br />

The presence <str<strong>on</strong>g>of</str<strong>on</strong>g> young, n<strong>on</strong>-school age children in the household is a possible time<br />

c<strong>on</strong>straining factor. The negative influence <str<strong>on</strong>g>of</str<strong>on</strong>g> children in the household <strong>on</strong> promoti<strong>on</strong><br />

resp<strong>on</strong>se is expected to be especially present when dealing with out-<str<strong>on</strong>g>of</str<strong>on</strong>g>-store promoti<strong>on</strong>s.<br />

Table 7.13 c<strong>on</strong>tains the resulting logistic regressi<strong>on</strong> coefficients for all promoti<strong>on</strong> types.<br />

Table 7.14 c<strong>on</strong>tains the results distinguishing between in-store and out-<str<strong>on</strong>g>of</str<strong>on</strong>g>-store promoti<strong>on</strong>s<br />

(Table A7.4).<br />
