Correct Answer: (a) progressive taxation combined with progressive expenditure
Solution:Redistribution of income and wealth are respectively the transfer of income and wealth (including physical property) from some individuals to others by means of taxation, monetary policies, welfare policies, public services, land reforms etc. This can be achieved with a combination of progressive taxation and progressive expenditure. A progressive tax is one where the average tax burden increases with income. It applies higher tax rates to higher levels of income. High-income families pay a disproportionate high share of the tax burden, while low-and middle-income taxpayers shoulder a relatively small tax burden. Regarding the distributive impact of public expenditure, the principle of maximum social welfare should be the underlying criteria of public spending. Therefore, progressive public expenditure (like free medical aid, free education, subsidized houses etc. to poors) is the best antidote to reduce income inequality existing in the society.
