This paper presents a model in which growth and geographic agglomeration of economic activities are mutually self reinforcing processes. Industrial agglomeration in one location spurs growth because it reduces the cost of innovation in that location through a pecuniary externality due to...

Major economic transitions, even when they are disruptive, do not occur instantaneously but rather occur over time, as regions within a country change at different rates. Accordingly, these dynamics may be reflected in a geographic lifecycle with different regions characterized by different...

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...

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...

This paper constructs a model of endogenous growth and endogenous industry location where the two interact. We show that with global spillovers in R&D, a high growth rate and a high level of transaction costs are associated with relocation of the newly created firms to the South (the location...

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 examine the extent to which developing countries that do little, if any, research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has large `stocks of knowledge' from its cumulative R&D activities, a...

Successful innovation depends on the development and integration of new knowledge in the innovation process. In order to innovate successfully, the firm will combine different innovation activities. In addition to doing own research and development, firms typically are engaged in the acquisition...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behaviour of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...
