【主題】Equilibrium Imitation and Growth (written by Jesse Perla, and Christopher Tonetti, working paper)

【摘要】The least productive agents in an economy can be vital in generating growth by spurring technology diffusion. We develop an analytically tractable model where growth is created as a positive externality from risk taking by firms at the bottom of the productivity distribution imitating more productive firms. Heterogeneous firms choose to produce or pay a cost and search within the economy to upgrade their technology. Sustained growth comes form the feedback between the endogenously determined distribution of productivity, as evolved by past search decisions, and an optimal forward looking search policy. The growth rate depends on characteristics of the productivity distribution, with a thicker tailed distribution leading to more growth.
