Size and determinants of shadow economies in the Baltic States

This study develops and estimates an index of the size of shadow economies in Estonia, Latvia and Lithuania, and analyses the factors that influence participation in the shadow sector. The index can be used to track shadow economies through time or across sectors and therefore is a useful tool to evaluate the effectiveness of policies aimed at reducing the size of shadow economies. Our results suggest that the shadow economy in Latvia in 2010 is considerably larger than in neighbouring Estonia and Lithuania. While the shadow economy as a percentage of GDP in Estonia contracted from 2009 to 2010, it expanded in Latvia and Lithuania. An important driver of shadow activity in the Baltic States is entrepreneurs' dissatisfaction with and distrust in the government and the tax system. We also find that involvement in the shadow economy is more pervasive among younger firms and firms in the construction sector. The findings of this study have a number of policy implications: (i) the relatively large size of shadow economies in the Baltic States and their different expansion/contraction trends cause significant error in official estimates of GDP and its rates of change; (ii) tax compliance can be encouraged by addressing the high level of dissatisfaction with the tax system and with government (e.g., making tax policy more stable and increasing the transparency with which taxes are spent), and (iii) significant scope exists for all three governments to increase their tax revenues by bringing entrepreneurs 'out of the shadows'.
