Generally, both the party that initiates such renegotiations and the time at which renegotiations are launched determine the outcome of the PPP's renegotiated remuneration. This effect is moderated by the degree of contract specificity and by a decrease in demand. Specifically, when the public client initiates the renegotiation of an incomplete contractual agreement due to a decrease in demand, it can successfully reduce the remuneration of the PPP.}, subject = {Public Private Partnership}, language = {en} } @article{LohmannRoetzel2014, author = {Lohmann, Christian and R{\"o}tzel, Peter}, title = {Opportunistic behaviour in renegotiations between public-private partnerships and government institutions: Data on public-private partnerships of the German armed forces}, series = {International Public Management Journal}, volume = {17}, journal = {International Public Management Journal}, number = {3}, doi = {DOI: 10.1080/10967494.2014.935245}, pages = {1 -- 24}, year = {2014}, abstract = {This study analyzes survey data on public-private partnerships (PPPs) of the German Armed Forces. The analyzed PPPs are unique in that the German Federal Ministry of Defence, a government institution, has a dual role as a main shareholder and a major customer. Drawing on these data, the present article analyzes how a government institution influences a PPP's set of objectives and shows that the conflict of interest with respect to monetary objectives between the government institution and the PPP as a whole is low in such partnerships. Furthermore, the article examines the opportunistic behavior of PPPs in contractual renegotiations where the government institution acts as a customer. The results show that, although such behavior indeed occurs, it does not concern monetary issues, since the government institution can control the monetary objectives of PPPs in which it is a main shareholder. Third, this study also analyzes and identifies certain exogenous factors that may influence the level of opportunistic behavior exhibited by the examined PPPs, providing evidence on the causes and effects of such behavior and indicating how it can be limited by the government institution.}, subject = {Public Private Partnership}, language = {en} } @article{LohmannRoetzel2013, author = {Lohmann, Christian and R{\"o}tzel, Peter}, title = {Einfluss des {\"o}ffentlichen Anteilseigners auf Public Private Partnerships: Eine empirische Untersuchung am Beispiel der Public Private Partnerships der Bundeswehr}, series = {Journal of Business Economics}, volume = {2013}, journal = {Journal of Business Economics}, number = {2}, doi = {10.1007/978-3-658-02429-1_4}, pages = {71 -- 88}, year = {2013}, abstract = {The present article analyzes the influence of the public shareholder on public-private partnerships (PPPs) that support public projects by supplying essential goods and services. The empirical analysis examines public-private partnerships involving the German Federal Ministry of Defense. The main characteristic of these PPPs is the dual role of the German Federal Ministry of Defense, which appears simultaneously as public shareholder and public purchaser. The paper shows that the government institution decisively determines monetary objectives and consequently the entire system of objectives. The most important monetary objective of PPPs is cost minimization, in contrast to profit maximization, which is commonly the objective of private shareholders. By determining the monetary objectives of such partnerships, the government institution prevents the opportunistic behavior of PPPs with regard to the level of charges for goods and services, which is commonly part of renegotiations if the government institution changes the demand for goods and services. Compared to wholly government-funded public projects, PPPs offer an opportunity to use the capital, competence and economic efficiency of private economic subjects without increasing the transaction costs commonly associated with the opportunistic behavior exhibited by PPPs with regard to the level of charges.}, subject = {Public Private Partnership}, language = {de} } @article{ChristianRoetzel2011, author = {Christian, Lohmann and R{\"o}tzel, Peter}, title = {Welchen Einfluss nehmen {\"o}ffentliche Anteilseigner auf Public Private Partnerships?
