We investigate social insurance in a dynamic Mirrlees' (1971) economy for which each agent's labor market productivity is the product of her stochastic and privately observed ability and an aggregate, publicly observed, ...

When microeconomic adjustment is lumpy, the VAR-estimated persistence of the corresponding aggregated variable is downward biased. The extent of this bias decreases with the level of aggregation, yet convergence is very ...

Decomposition of plant material influences soil aggregation dynamics in ways that are still poorly understood, especially for Oxisols, in which oxides are believed to play a dominant role. In an incubation experiment, we ...

Aggregate hierarchy and porosity changes in aggregate beds as a consequence of wetting-drying cycles were studied in two Andisols and one Mollisol from Chile, collected at two depths. Bulk density and indirect tensile ...
