摘要:I present a model of endogenous innovation where firms undertake in-house research and development (R&D). The concentration of sales and R&D resources determines the scale and efficiency of R&D operations and rate of productivity growth. In zero-profit equilibrium, R&D expenditure is one component of total fixed costs and determines the number of active firms. This feedback generates interdependent pricing, investment, and entry/exit decisions. The (jointly determined) rate of growth and numbe...

摘要:To explore the link between a tighter environmental policy and economic growth, we employ an endogenous growth model with endogenous technological progress in abatement technologies. The environment, which is modelled as a renewable resource, acts both as a public consumption good and as a public input into production. The entire transition towards a new balanced-growth path after a tightening of environmental policy is computed analytically. We find sharp contrasts between short-run and long-...
