We study the effects of COVID-19, and ensuing lockdown fiscal policies, on welfare different age-groups within a life-cycle macroeconomic scheme, adapted from Gertler (1999), where pandemic is represented as shock to mortality rate. obtain two main results. First, we show that policies have negative impact dynamics economic younger agents relative older agents, thus providing analytical support...

Choice of the optimal number and sequence of breeds in a periodic cross was determined by comparing the trade-off between increased utilization of breed differences and decreased utilization of heterosis. It was shown that the change in mean efficiency resulting from adding the next best breed to the best conventional n-breed rotation is always less than the change in efficiency predicted from ...

Our'previous study (Auerbach, Gokhale, and Kotlikoff [1991]) introduced the concept of generational accounting, a method of determining how the burden of fiscal policy falls on different generations. It found that U.S. fiscal policy is out of balance in terms of projected generational burdens. This means that either current generations will bear a larger share (than we project under current law...

Defining the contributions of dispersal, reproductive mode, and mating system to the population structure of a pathogenic organism is essential to estimating its evolutionary potential. After introduction of the devastating plant pathogen, Phytophthora capsici, into a grower's field, a lack of aerial spore dispersal restricts migration. Once established, coexistence of both mating types results...

Until recently, the best performing copying garbage collectors used a generational policy which repeatedly collects the very youngest objects, copies any survivors to an older space, and then infrequently collects the older space. A previous study that used garbagecollection simulation pointed to potential improvements by using an Older-First copying garbage collection algorithm. The OlderFirst...
