The Financial and Economic Implications of Underground Economy: The Nigerian Perspective

Abstract

The economic and financial effect of underground economy in all emerging countries is of tremendous concern. Sometimes due to the inputs of the sector to economic growth of nations, it is usually assumed that the government has nothing to lose, meanwhile it goes beyond the seemingly economic benefits, but provides an avenue whereby the government has to suffer financial losses through unavoidable and inherent tax evasions. This study evaluates the impact of shadow economy using the transaction approach and the MIMIC approach which helped to determine the size of the shadow economy as a percentage of GDP and the tax revenue losses suffered by the government for a period spanning from 1991 to 2018. Ordinary least squares method is used to examine the impact of tax revenue earned and lost on Nigeria’s GDP. The regression results indicate that tax revenue earned has a significant positive impact on economic growth, while the tax revenue loss has a significant negative influence on GDP. The study finds that underground economy activities do more harm to the government than good and is also detrimental to Nigeria’s economic progress. Therefore the suggestion among others is that the legal activities among them should be formalized and taxed while the unlawful ones should be exterminated
