Shadow economy over the business cycle: How do formal and informal cycles interact?

In this thesis, first, relying on a two-sector dynamic general equilibrium model, I construct quarterly estimates of shadow economy size for 15 advanced economies for a time period from 1960 to 2010. This gives me the largest quarterly shadow economy size data in the literature. Next, using this novel data, I provide a comprehensive empirical characterization of the linkages between the formal and the shadow economies around the business cycles. The results indicate that the shadow economy size as a percentage of official GDP is generally countercyclical and a larger shadow economy is associated with a larger amplitude and longer duration of formal expansions and larger amplitude of formal recessions.
