This paper compares reward systems to intellectual property rights (patents and copyrights). Under a reward system, innovators are paid for innovations directly by government (possibly on the basis of sales), and innovations pass immediately into the public domain. Thus, reward systems engender...

We study the optimal allocation of R&D resources in an endogenous growth model with an innovation network, through which one sector's past innovations may benefit other sectors' future innovations. First, we provide closed-form sufficient statistics for the optimal path of R&D resource...

The Chinese government has been using various subsidies to encourage innovations by Chinese firms. This paper examines the allocation and impacts of innovation subsidies, using the data from the China Employer Employee Survey (CEES). We find that the innovation subsidies are preferentially...

The standard view of U.S. technological history is that the locus of invention shifted during the early twentieth century to large firms whose in-house research laboratories were superior sites for advancing the complex technologies of the second industrial revolution. In recent years this view...

Recent efforts to endogenize technological change in climate policy models demonstrate the importance of accounting for the opportunity cost of climate R&D investments. Because the social returns to R&D investments are typically higher than the social returns to other types of investment, any...

Support for R&D subsidies relies on empirical evidence that R&D "spills over" between firms. But firm performance is affected by two countervailing R&D spillovers: positive effects from technology spillovers and negative business stealing effects from R&D by product market rivals. We develop a...
