Answer and Explanation:
Efficiency and equality:
We have given the information that there are two areas one has many small school and another has few large schools. The area which has many small schools faces a large competition as there are large numbers of school in that area. In order to maintain equality and efficiency the voucher system should announced in the area which has few large schools. Introducing the voucher system in this few large school region help to maintain equality as there is less competition. Whereas the introduction of the voucher system in an area which has many large schools increases the inequality as there is high competition and this inequality also stimulated by the migration factor. So, these are the effects of voucher system in different areas.
