一般注記This study constructs a variety expansion growth model with public research spending, in which public researchers raise the productivity of private R&D. We show that the relationship between public research spending and the growth rate follows an inverted U-shape.This is because public research spending increases private R&D productivity, but crowds out labor input to private R&D. It is also shown that the welfare-maximizing level of public research spending is below the growth-maximizing level. With regards to tax policy, a zero-profit tax maximizes both growth and welfare. Finally, the study analyzes the stability of the steady state, showing that the equilibrium is indeterminate when the government’srevenue source depends on asset income tax.
