PPP offers numerous benefits to both public and private partners in delivery
of infrastructure projects. However this partnership also involves great
risks which have to be adequately managed and mitigated. Private partners are
especially sensitive to revenue risk, since they are mostly interested in the
financial viability of the project. Thus they often expect public partners to
provide some kind of risk-sharing mechanism in the form of Minimum Revenue
Guarantees or abandonment options. The objective of this paper is to
investigate whether the real option of abandoning the project increases its
value. Therefore the binominal option pricing model and risk-neutral
probability approach have been implemented to price the European and American
abandonment options for the Build-Operate-Transfer (BOT) toll road
investment. The obtained results suggest that the project value with the
American abandonment option is greater than with the European abandonment
option, hence implying that American options offer greater flexibility and
are more valuable for private partners. [Projekat Ministarstva nauke

The effectiveness of fiscal and monetary policy has been the center of debate between Keynesians and the monetarists for a long time. However, the results of numerous empirical studies are inconclusive, suggesting that none of the policies can be thought of as superior to the other and their relative effectiveness in any economy depends on the prevailing economic and political conditions at any point in time. In order to determine the influence of fiscal and monetary policy on the economic activity in Serbia, we employed unit root and cointegration tests, as well as the regression analysis on the series of quarterly data for the period 2003-2012. The results obtained show that monetary policy is more effective in stimulating economic growth comparing to fiscal policy. Hence, the overall conclusion is that government should pay more attention to the fiscal policy to improve its efficiency in the future
Public-private partnership (PPP) has been getting momentum in market economies since the 1990s. Originally, it was created as a way of financing infrastructure projects, but its application since then has covered areas such as education, healthcare, high technology and many others. As the bulk of research in the domain of PPP is on the microeconomic impact and the analysis of the success of concrete PPP projects, the aim of this paper is to integrate these findings into a broader framework depicting macroeconomic aspects of public-private partnership. The existing literature, although not as extensive, points to several aspects that may affect economic development on the local, regional, and national levels, with greater adoption of PPP projects and their implementation. The paper introduces explanations for the elements of risk sharing between public and private partners, economic benefits, and costs in PPP, as well as the specific PPP channels of influence on the national economy and the PPP system dynamic model. One of the objectives is the analysis of the existing concept for estimating macroeconomic impacts of PPP, which could be used for evaluating its potential contribution to the growth and development of the national economy.
