Does income inequality increase the shadow economy? Empirical evidence from Uganda

ABSTRACT This paper applies the autoregressive distributed lag bounds testing method to investigate the long- and short-run relationship between the size of the shadow economy and income inequality in Uganda. The findings reveal evidence of the long and short-run relationship between the shadow economy and income inequality. We find that a rise in income inequality significantly increases the size of the shadow economy in Uganda, all else equal. These results are robust to the use of alternative econometric methods. At the policy level, instituting income redistribution policies to uplift the standard of the poor, improving resource allocation to productive sectors of the economy, reforming the tax system and macroeconomic environment, and implementing political and institutional reforms to address corruption could be viable policy options to address informality in Uganda.
