Support for many R&D and technology policies relies on empirical evidence that R&D ‘spills over’ between firms. But there are two countervailing R&D spillovers: positive effects from technology spillovers and negative effects from business stealing by product market rivals. We develop a...

We analyse the determinants of the decline in measured research productivity (the patent/R&D ratio) using panel data on manufacturing firms in the US for the period 1980-93. We focus on three factors: the level of demand, the quality of patents, and technological exhaustion. We first develop an...

In our model multiple innovators compete against each other by submitting investment proposals to an investor. The investor chooses the least expensive proposal and when to invest in it. Innovators have to provide costly effort and they learn privately the cost of investing. Multiple efforts...

Can stringent labor laws be efficient? Possibly, if they provide firms with a commitment device to not punish short-run failures and thereby incentivize the pursuit of value-maximizing innovative activities. In this paper, we provide empirical evidence that strong labor laws indeed appear to...

This paper examines the relationship between innovation and firms' dependence on external capital by analyzing the innovation activities of privately-held and publicly-traded firms We find that public firms in external finance dependent industries generate patents of higher quantity, quality,...

This Paper surveys the economic literature on the impact of trade unions on innovation. There are many theoretical routes through which unions may have an effect on innovation, for example through their effects on relative factor prices, profitability and their attitudes towards the introduction...

This paper looks at the genesis of innovation in the United States from a territorial perspective. The analysis aims to disentangle the impact of local R&D expenditure from other contextual conditions supportive of the process of innovation. Particular emphasis is devoted to the role of...

This paper analyses the geography of innovation in China and India. Using a tailor-made panel database for regions in these two countries, we show that both countries exhibit increasingly strong polarisation of innovative capacity in a limited number of urban areas. But the factors behind this...

We investigate firms' incentives to locate in the same region to gain access to a large pool of skilled labour. Firms engage in risky R&D activities and thus create stochastic product and implied labour demand. Agglomeration in a cluster is more likely in situations where the innovation step is...

We find that institutional ownership in publicly traded companies is associated with more innovation (measured by cite-weighted patents). To explore the mechanism through which this link arises, we build a model that nests the lazy-manager hypothesis with career-concerns, where institutional...
