Public-Private Partnership (PPP) infrastructure initiatives have been hailed as a formula for driving the socio-economic progress of developing nations. These national PPP programs prioritize efficiency by capitalizing on the private sector's abilities to plan, fund, construct, and oversee the ongoing operation of public facilities from a long-term perspective. However, despite the comprehensive trend of bolstering PPP programs in developing countries, there exists substantial heterogeneity in the development of these programs, even among neighboring nations. Furthermore, PPP programs are enveloped with complexities at various levels, making them increasingly challenging. To elucidate the diverse performance of national PPP programs, the thesis is aimed to examine the PPP programs of Eastern European and Central Asian countries, drawing from the projects that have been procured thus far.
