Hi Andrey - thank you for your comment. How indeed to find the money to focus on firms, clusters and cities? In resource-poor environments, public-private partnerships could certainly bolster the public purse for infrastructure investments. Often, changes in policy might require institutional commitment to regulatory reforms, without big financial commitments. If you're interested, the World Bank's study on 'Planning, Connecting and Financing Cities' documents innovative ways of paying for city-level investments.
