Plant Size Distribution

We estimate the effects of electricity shortages on Indian manufacturers, instrumenting with supply shifts from hydroelectric power availability. We estimate that India's average reported level of shortages reduces the average plant's revenues and producer surplus by 5 to 10 percent, but average productivity losses are significantly smaller because most inputs can be stored during outages. Shortages distort the plant size distribution, as there are significant economies of scale in generator costs and shortages more severely affect plants without generators. Simulations show that offering interruptible retail electricity contracts could substantially reduce the impacts of shortages. (JEL D24, L60, L94, O13, O14, Q41)

Plant Size Distribution

This study describes forest succession following slash-and-burn agriculture in central Amazonia, based on four chronosequences (22 sites) of 2- to 25-y-old secondary regrowth and mature forest. Biomass accumulated in the form of a saturation curve: 25 y of regrowth restored half of the mature-forest biomass, 75% would be restored after an estimated 175 y. Biomass accumulation was accompanied by a rapid decrease in woody plant density and an increase of the positive skew of plant size distribution. Liana biomass share declined from 5.0% in young to 1.9% in old regrowth, and 1.3% in mature forest, whereas the share of palms was low (0.5%) in young regrowth and high in old regrowth (1.8%) and mature forest (2.2%). 25-y-old regrowth was similar with mature forest in respect to woody plant density and growth-form composition, but both the plant size distribution and the number of stems per plant differed strongly from mature forest. A moderate increase in land use had only minor effects on biomass accumulation, but profoundly changed structural characteristics of regrowth, pointing to a high vulnerability to degradation. Thus, the sustainability of slash-and-burn in central Amazonia may be lower than the rapid initial biomass accumulation would make it seem.
