German Nuclear Phase-out Policy: Effects on European Electricity Wholesale Prices, Emission Prices, Conventional Power Plant Investments and Eletricity Trade

Traber, Thure; Kemfert, Claudia - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2012

The German decision to finally phase-out nuclear electricity has led to a debate on its effects on electricity prices, emission prices in the European emission trading system, as well as on international electricity trade. We investigate these effects with a Electricity market model for Europe...

Corporate Espionage

Billand, Pascal; Bravard, Christophe; Chakrabarti, Subhadip - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that...

The Incentives for Takeover in Oligopoly

Inderst, Roman; Wey, Christian - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2004

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of .rms and of the insiders. share of total industry gains due to the...

The Effect of Market Power on Electricity Storage Utilization: The Case of Pumped Hydro Storage in Germany

Schill, Wolf-Peter; Kemfert, Claudia - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

In this paper, we develop the game-theoretic electricity market model ElStorM that includes the possibility of strategic electricity storage. We apply the model to the German electricity market and analyze different realistic and counterfactual cases of strategic and non-strategic pumped hydro...

Gone with the Wind?: Electricity Market Prices and Incentives to Invest in Thermal Power Plants under Increasing Wind Energy Supply

Traber, Thure; Kemfert, Claudia - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

The increased wind energy supplied to many electricity markets around the world has to be balanced by reliable back upunits or other complementary measures when wind conditions are low. At the same time wind energy impacts both, the utilization of thermal power plants and the market prices....

Mergers in Imperfectly Segmented Markets

Baake, Pio; Wey, Christian - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a "high-demand" and a "low-demand" market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria...

Would I Care if I Knew?: Image Concerns and Social Confirmation in Giving

Kritikos, Alexander S.; Tan, Jonathan H. W. - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2014

This paper experimentally investigates the nature of image concerns in gift giving. For this, we test variants of dictator and impunity games where the influences of social preferences on behavior are kept constant across all games. Givers maximize material payoffs by pretending to be fair when...

A Nation-Wide Laboratory: Examining Trust and Trustworthiness by Integrating Behavioral Experiments into Representative Surveys

Fehr, Ernst; Fischbacher, Urs; Rosenbladt, Bernhard von; … - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2002

Typically, laboratory experiments suffer from homogeneous subject pools and selfselection biases. The usefulness of … method integrating interactive experiments and representative surveys thereby overcoming crucial weaknesses of both … approaches. One of the major advantages of our approach is that it allows for the integration of experiments, which require …

The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

Duso, Tomaso; Herr, Annika; Suppliet, Moritz - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2014

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of...

An Exact Solution Method for Binary Equilibrium Problems with Compensation and the Power Market Uplift Problem

Huppmann, Daniel; Siddiqui, Sauleh - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2015

We propose a novel method to find Nash equilibria in games with binary decision variables by including compensation payments and incentive-compatibility constraints from non-cooperative game theory directly into an optimization framework in lieu of using first order conditions of a...
