The paper decomposes a geographical concentration index to examine the temporal scope of a spillover, which is the period of time over which one firm's activity directly affects the location of other firms' activities. Natural advantages are fixed over reasonably long time periods, but if...

The paper decomposes a geographical concentration index to examine the temporal scope of a spillover, which is the period of time over which one firm’s activity directly affects the location of other firms’ activities. Natural advantages are fixed over reasonably long time periods, but if...

The paper decomposes a geographical concentration index between time-invariant and time varying location factors to examine the temporal scope of a spillover. This is the period of time over which one firm's activity directly affects the location of other activities in the same industry. An...

The provision of financial assistance to industry has formed a growing and important part of the economic development policies of many local authorities. However, assessments of these policies have suffered from a number of drawbacks. In particular, they have tended to focus on the employment...

The paper argues that in order to use macro-evaluation techniques to calculate the employment effect of a policy over some sub-period after policy commencement, it is necessary to determine the rate at which policy jobs are lost. Crucially, it is the rate at which jobs cease to be attributable...

Ellison and Glaeser's (1997) index of geographical concentration distinguishes between natural advantages and spillovers as a source of industrial agglomeration, but the well-known 'observational equivalence' means little is known about the relative importance of these. This paper uses the...
