The moderating role of governance environment on the relationship between risk allocation and private investment in PPP markets: Evidence from developing countries

PPPs have become a popular way to supply infrastructure around the world. However, compared with developed countries, most developing countries have failed to attract private investment over the past years. Risk allocation and governance environment (e.g., the extent of public participation, the level of political stability, the quality of public services, the ability of regulations, abiding the law, and the extent of corruption) may be important factors. To test the hypotheses, using about 4560 PPP projects in 138 developing countries from 2002 to 2015, this paper applies the Tobit regression model to investigate the interaction effect of governance environment and risk assumed by private partners on private investment. Results indicate that private partners assume that less risk can attract more private investment, and that a higher level of governance (control of corruption, government effectiveness, regulatory quality, and rule of law) reduces the negative influence of risk assumed by private partners on private investments.
