Does entrepreneurship cause urban economic growth and if so how large is the impact? Empirical analysis of such question is hampered by endogeneity. This paper uses two different sets of variables – the homestead exemption levels in state bankruptcy laws from 1975 and the share of MSA overlaying aquifers - to instrument for entrepreneurship and examine urban growth between 1993 and 2002. Despite using different sets of instrumental variables, the ranges of 2SLS estimates are similar, further supporting the significant impact of entrepreneurship on urban growth.
This paper examines the impact of government guaranteed small business loans on urban economic growth, and compares the growth impacts of government versus market financed entrepreneurship. OLS estimates indicate a significant and positive relation between the Small Business Administration’s guaranteed loans and metropolitan growth between 1993 and 2002. However, first-difference and instrumental variable regressions show no growth impact from government guaranteed loans. In contrast, market entrepreneurship significantly and positively contributes to local economic growth.
Is it possible, simply by asking a few members of a community, to identify individuals who are best placed to diffuse information? A model of diffusion shows how members of a community can, just by tracking gossip about others, identify those who are most central in a network according to “diffusion centrality” – a network centrality measure that predicts the diffusion of a piece of information seeded with a network member.
Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are desirable because the private sector is more efficient, the contract that optimally trades demand risk, user-fee distortions and the opportunity cost of public funds is characterized by a minimum revenue guarantee and a cap on the firm’s revenues. Yet income guarantees and revenue sharing arrangements observed in practice differ fundamentally from those suggested by the optimal contract.
This paper analyzes the impact of the changing telecom environment on the nature of disputes that arise in this sector. It focuses on the need to resolve disputes in an efficacious, expeditious and transparent manner to ensure unhindered growth of the telecom sector. The paper draws upon several country specific examples to show how this subject is receiving increasing attention and has in fact become a significant feature of regulatory initiative.
