Laureates 2011


The Hans-Jürgen-Ewers-Prize 2011 was awarded at the 10th Conference on Applied Infrastructure Research at Berlin University of Technology on October 7, 2011. The Laureates of the Hans-Jürgen-Ewers-Prize 2011 were:

Carmine Guerriero


for his research work on "The Political Economy of (De)Regulation: Theory and Evidence from the U.S Electricity Market".

After obtaining his B.A. degree in Economics from the University of Milan/Italy, Carmine Guerriero went to University of Chicaco to complete his M.A. In addition, he gained a Master of Science from the London School of Economics. In 2010 Carmine Guerriero successfully defended his PhD thesis on “Endogenous Legal Systems: Theory and Evidence” at the University of Cambridge. Currently he works as assistant professor at the Center for Law and Economics at the University of Amsterdam. 

In his recent paper Dr. Carmine Guerriero deals with the optimal trade off between allocative efficiency and the stimulation of cost-reducing investment under two different market regimes, competition and regulation, in a world where the demand is inelastic. Its main question is: "How do politicians and regulators incentives shape the allokative efficiency-investment inducement trade off when market institutions are designed?" He builds a model for thinking about this issue, and explores its empirical implications using U.S. electricity data.

Even if some studies have used electricity data to show that deregulation can deliver lower input uses and costs, no previous paper has evaluated the determinants of its introduction. The main contribution of Carmine Guerriero’s work is to formalize and test a property rights - on sunk investments - theory of “endogenous market institutions”. This work is complementary to a recent literature that see the choice of regulatory institutions as a response to both efficiency-enhancing and rent seeking concerns by the politicians responsible of institutional design and the regulators shaping the extent of asymmetric information.

Dr. Carsten Sander


for his PhD thesis “Cooperations in the Energy Sector – An Empirical Analysis Of Municipal Power Suppliers In Germany”.

Carsten Sander studied Economics and Business Administration at the Universities of Münster and Lund/Sweden. There he gained a bachelor in Business Administration and a diploma degree in Economics. His PhD thesis, supervised by Prof. Theresia Theurl of the Institute of Cooperative Research, Münster, was defended in January 2011 and evaluated with “summa cum laude”. Now he works at the division for corporate planning and controlling of RWE Power AG.

With the recent liberalization and re-regulation of the energy sector the market conditions for municipal utilities changed fundamentally, which required an adaptation of new market strategies, processes and structures. The thesis of Carsten Sander systematically studies strategies of municipal utilities to cooperate with each other. Based on value chains, the potential for cooperation is also checked empirically, and critical variables for the success of joint ventures are identified.

The model results show that a high compatibility of goals and a similar organizational structure are keys factors for a successful cooperation. A negative effect is correlated e.g. with a common history of firms. Other interesting findings are the pronounced role of a standardization of IT and business processes. The theoretically well founded and empirically tested results are an important, practice-oriented contribution to the further development of corporate structures in the energy sector.
