New Approaches to Spatial Economics.

ABSTRACT This paper looks at the linkages between three recent developments in spatial economics that in combination have changed the way that economic growth is viewed. These new approaches are that of the New Growth Theory, the measurement of geographical economic convergence, and the role of infrastructure in stimulating economic growth. In combination these developments may combine to provide a different perspective on why regions often grow at differential rates, ways of measuring these differences, and possible policy interventions to manipulate geographical variations in the growth process. The paper argues, however, that these concepts, while they may offer new insights, are nevertheless unlikely to provide a complete picture of why spatial economic divergence is widespread nor a set of policy instruments that can be simply deployed to ameliorate such discrepancies.
