Based on the electricity consumption approach, this study examined empirically (among other determinants) the impact of corruption and multinational firms (MNEs) on the relative size of the informal economy in Russia's regions in 1995–2012. Strong evidence is provided of the positive effect of corruption on the informal regional economies. The significant role of MNEs and regulation in curbing informal activities is revealed. A larger informal economic sector is observed in regions with a higher number of local firms and unemployment. An integrated strategy of dealing with corruption and informal businesses is suggested to be more effective in reducing informal practices.
