Thus, for the development of linkages, it matters which infrastructure investments are prioritized. This in turn will depend upon how the stock of infrastructure has evolved historically relative to income, the pattern and pace of urbanization, the economic and institutional structures of countries (Fay et al , 2017) as well as how the investments are likely to induce linkages with local private sector activity. However, even at low levels of infrastructural development, there is no guarantee that new infrastructure of the same kind w ill result in similar outcomes across countries or sectors. For example, although there is a link between power outages and productivity of firms, these impacts will vary between countries and sectors, depending on how acute the problem of power provision in the country is, and how dependent a sector is on continuous power provision for its production (Moyo, 2013).
