Resource allocation refers to lost government tax revenue resulting from the tax incentive. The second cost refers to the situation when the tax incentives lead to too much investment in a certain area of the economy and too little investment in other areas of the economy. Revenue cost is associated with enforcing the tax incentive and monitoring who is receiving the incentive and ensuring they are properly deserving of the incentive. Therefore, the higher and the more complex the tax incentive, the higher the compliance costs because of the larger number of people and firms attempting to secure the tax incentive. The final cost is similar to the third in that it relates to people abusing the tax incentive. Corruption occurs when there are no clear guidelines or minimal guidelines for qualification.
