Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience...

This paper presents estimates of the size of the shadow economy in 76 developing, transition, and OECD countries, which are derived by combining figures from different estimation methods. We describe and discuss the strengths and weaknesses of the different estimation methods. We find that the...

This paper assesses changes in the size and scope of government in 24 transition economies. Whereas these governments have retrenched in terms of public expenditures in relation to GDP, as well as public employment as a share of population, some indicators suggest that size remains high (e.g.,...
