Final answer:
The redistribution plan in this society affects the total income of Yakov and Ana. Yakov's decision to work less and pay taxes results in a transfer of income to Ana. Hence, the redistribution plan impacts the total income in this society.
Step-by-step explanation:
The redistribution plan in this society affects the total income of Yakov and Ana. Without the redistribution plan, Yakov would retain $72,000 and Ana would end up with $43,000. However, with the redistribution plan, Yakov decides to work less and earns an income of $75,000, of which $15,000 will be owed in taxes. The $15,000 in taxes will be transferred to Ana by the government, and as a result, Ana's total income (including the government payment received) is now $23,000. Therefore, the redistribution plan has an impact on the total income in this society.
