ABSTRACT
The change in attractiveness to the two sets of people is not determined solely by the amount of the change in wage and the nature of the relevant demand for labour, but also by certain other conditions associated with the methods of engagement in vogue. Pro tanto, the effect of this is to check the free movement of labour from centres of falling demand to centres of rising demand, thus impeding its most advantageous employment. In the face of an enforced rise there are three possibilities. The first of the possibilities will be realised if the method of engagement of labour is entirely haphazard and engagements are for short periods. The second, if the method is such that all insiders are preferred to any outsiders, but among themselves are on an equal footing. The third if all workpeople interested in the place or occupation are implicitly or explicitly arranged, for purposes of engagement, upon a preference scale.
