6. All of the following are costs of inflation, except A. money neutrality. B. menu costs. C. shoe-leather costs. D. redistribution of wealth.

The correct answer is A. money neutrality.<br /><br />Money neutrality refers to the idea that changes in the money supply only affect nominal variables (such as prices) and do not affect real variables (such as output or employment). In other words, it suggests that changes in the money supply do not have any real impact on the economy in the long run.<br /><br />On the other hand, menu costs, shoe-leather costs, and redistribution of wealth are all costs associated with inflation:<br /><br />- Menu costs refer to the costs incurred by businesses when they have to change their prices frequently due to inflation. This can include the cost of printing new menus, updating price tags, or changing price labels.<br /><br />- Shoe-leather costs refer to the costs incurred by individuals when they have to make more frequent trips to the bank or ATM due to inflation. This can include the time and effort spent on these activities.<br /><br />- Redistribution of wealth refers to the fact that inflation can lead to a redistribution of wealth from lenders to borrowers. This is because inflation erodes the value of money over time, so borrowers who repay their loans in the future will be repaying with money that is worth less than when they originally borrowed it.<br /><br />Therefore, the correct answer is A. money neutrality, as it is not a cost of inflation.
