However, the non-observed country-specific effect and potential endogeneity may cause the results to be biased. This paper utilizes panel data from 1999 to 2005 for at most 83 countries and employ fixed effect model and GMM method to overcome this shortcoming.

Understanding the causes of shadow economy could help the government make reasonable policy to reduce the size of shadow economy and then improve the capacity of tax collection. This paper focuses on Taiwan’s case and employs both standard OLS and VAR model to estimate the impacts of various kinds of specific taxes and other variables on Taiwan’s shadow economy. The results show that business tax has significant positive effect, which implies that a government should consider a business tax reduction to reduce the size of shadow economy because this way is least costly.
