Agents facing idiosyncratic productivity shocks cannot perfectly commit to repay their loans, but the threat of credit market exclusion specifies endogenous debt limits preventing default in equilibrium.

The documented ability of infectious retroviruses to cause cancer has greatly contributed to the discovery of ERVs. It also reinforced the concept that ERVs are causative agents of many cancers, a notion that historically ha...
