''The Emergence of Agriculture: Trickle-Down Growth and Climate Change''
( 2012, Vol. 32 No.1 )
This paper analyzes a model of the transition to agriculture by allowing heterogeneous agents to make the decision on whether to engage in farming or foraging. The threshold level, which divides foragers from farmers, depends on both agricultural productivity and foraging efficiency. As agricultural productivity improves, farming becomes possible to low-skilled agents, which leads to further improvement in agricultural productivity. Due to this trickle-down mechanism, the allocation of labor to agriculture magnifies the persistence of growth dynamics. The model also explains that a temporary climate deterioration can initiate the transition to agriculture by lowering foraging efficiency.
