We investigate how increases in publication delays have affected the life-cycle of publications of recent Ph.D. graduates in economics. We construct a panel dataset of 14,271 individuals who were awarded Ph.D.s between 1986 and 2000 in US and Canadian economics departments. For this population...

Advanced human capital requires "basic" human capital as an input. Physical capital does not, in general, have such hierarchical structure. This paper models optimal investment in hierarchical human capital as well as nonhierarchical physical capital. The authors analyze the steady state,...

Previous literature has shown that local indeterminacy and local instability can arise in two-sector models when factor market distortions create a divergence between capital intensity ranking of the sectors on a physical basis and on a value basis. We identify a previously unnoticed source of...

The paper argues that multiple equilibria-whether non-stationary or stationary- are a generic property of dynamic rational expectations models. In light of this, this paper proposes a selection criterion for choosing between these multiple equilibria in an important class of dynamic rational...
