TY - RPRT AU - Schneider, Friedrich AU - Klinglmair, Robert TI - Shadow Economies around the World: What Do We Know? PY - 2004/Mar/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 1043 UR - https://www.iza.org/index.php/publications/dp1043 AB - Using various statistical procedures, estimates about the size of the shadow economy in 110 developing, transition and OECD countries are presented. The average size of the shadow economy (in percent of official GDP) over 1999-2000 in developing countries is 41%, in transition countries 38% and in OECD countries 18.0%. An increasing burden of taxation and social security contributions combined with rising state regulatory activities are the driving forces for the growth and size of the shadow economy. If the shadow economy increases by one percent the annual growth rate of the “official” GDP of a developing country (of a industrialized and/or transition country) decreases by 0.6% (increases by 0.8 and 1.0 respectively).
