Population

A population increase can also lead to the PPC shifting outwards , A larger population will result in an increae in producion , as shown in Figure 1.6 (a) . On the other hand , if worjers migrate to other countries , there will be a reduction in population . For example , Malaysians migrating to Singapore to work because of more atractive salaries or incentives , will result in the PPC shifting inwards as an be seen in Figure 1.6(b) .
