“…Though many studies consider what barriers firms face, few Nigeria-focused papers effectively measure the impact of different constraints on a group of firms and none appear to consider what factors vary the impact of constraints between different firms or the extent to which funding results in behaviours that overcome them. A far from exhaustive list of general barriers which may impact additionality includes: lack of management experience, poor location and regulation, general economic conditions, poor infrastructure, corruption, low demand for products and services, poverty (Okpara and Wynn, 2007), inadequate supply of electricity and water, poor road network, access to raw material and market, (Nneka, 2015) lack of action plan, lack of marketing skill, lack of research appreciation and technical expertise (Ezekiel et al , 2016), bias against domestically produced goods, lack of access to foreign exchange, competition from large firms, unfavourable government policies (Mambula, 2004) and unreliable power supply (Ofoegbu, et al , 2013). Each of these constraints may inform research into additionality if it can be determined that they affect firms differently and can be overcome with finance, but no such study appears to have been conducted.…”
