We investigate overlapping contests in multi-divisional organizations in which an individual's effort simultaneously determines the outcome of several contests on different hierarchical levels. We show that individuals in smaller units are advantaged in the grand (organization-wide) contest for...

This paper estimates the non-linear impact of ICT network on motorway contribution to total factor productivity. Using dynamic panel data of OECD member countries, the paper finds that there exists a critical mass of broadband penetration rate which has the property that if this threshold level...
