This paper explores the introduction of collective risk-sharing elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset contingent risk-sharing arrangements. All arrangements raise aggregate welfare, as measured by equivalent variations. While...

We study numerically the inter- and intra-generational welfare consequences of alternative pension fund policies in response to unexpected demographic, financial and macro-economic shocks. Our analysis is based on an applied many-generation OLG model describing a small-open economy with...

This paper presents the first MIMIC (multiple indicator multiple causes) model estimate of the size and development of the shadow economy and of do-it-yourself (DIY) activities in Germany from 1970 to 2005. By 2005, they reached a level of about 17% and 4.94%. While the shadow economy has...

Using the MIMIC method, this paper is a first attempt to estimate the size of the shadow economy of 158 countries over the period 1991 up to 2015. In addition to performing a variety of robustness tests, this paper explicitly addresses endogeneity concerns to the use of GDP as cause and...

Estimations of the size and development of the shadow economy for 145 countries, including developing, transition and highly developed OECD economies over the period 1999 to 2003 are presented. The average size of the shadow economy (as a percent of "official" GDP) in 2002/03 in 96 developing...

This paper analyzes the influence of the shadow economy on corruption and vice versa. We hypothesize that corruption and shadow economy are substitutes in high income countries while they are complements in low income countries. The hypotheses are tested for a cross-section of 120 countries and...
