Dear Members! Sorry for the glaring omission in terms of not defining a technology cluster properly. By Technology Clusters I mean 'geographic agglomeration of high technology firms' like in Silicon Valley and Route 128 in Boston. There has been quite a bit of theoretical and empirical work in the area of innovativeness of firms clustered spatially that points towards both supply and demand side effiiciencies as well as R&D and Knowledge Spillovers etc. I am interested in the policy question: That is: Is there a role for governments to try to 'cultivate' these clusters or should they be left to market forces and private interests? and if yes, what is the appropriate set of policy bundle? Many governments try to create such regions of technological specialization through a series of active policy interventions. There are quite a number of interesting studies out there as well. I have seen quite a bit of econometric literature on the subject. I was wondering if someone has tried to do simulation modeling in this area? ACE-type models? or some other kinds...[or if someone knows about others who might be working in this area] I'd be grateful for any help/guidance on that.
