Revenue erosion through exemption and evasion in Cameroon, 1993
通过对喀麦隆企业的调查，发现企业税基因豁免和逃税而普遍侵蚀，企业愿意提供这些敏感信息，研究揭示了逃税企业的特征、与税务部门的互动及处罚情况。
The administration of tax statutes materially determines their economic effects. A survey of Cameroonian businesses, a country seemingly typical of its economic level, demonstrates widespread erosion of the tax bases paid by businesses through exemptions and evasion. Businesses seem willing to provide information on these potentially confidential activities. The survey provides information on the number of businesses evading taxes or having exemptions, on the characteristics of these businesses relative to others, on whether businesses maintain information of use to the tax administration, on the contacts between the administration and businesses affecting evasion, and on penalties imposed by the administration.
