In 2008, the European Commission investigated E.ON, a large and vertically integrated electricity company, for the alleged abuse of a joint dominant position by strategically withholding generation capacity. The case was settled after E.ON agreed to divest 5,000 MW generation capacity as well as...

We evaluate the effects of homogeneous subsidies granted for emission-free electricity generation on market outcomes and social welfare. We use an analytical model to assess the conditions under which such subsidies increase efficiency of wholesale energy and capacity markets. While the...

The widespread use of markets leads to unprecedented material well-being in many societies. We study whether market interaction, as a side effect, erodes moral values. An encompassing understanding of the virtues and vices of markets, including their possible impact on moral values, is necessary...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

Redistributive grants schemes, such as fiscal equalization, are a common characteristic of local public finance in several countries. However, large and small jurisdictions are treated differently by the respective fiscal equalization schemes that often tend to favour larger jurisdictions. This...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

We derive the optimal contract between a principal and a liquidity-constrained agent in a stochastically repeated environment. The contract comprises a court-enforceable explicit bonus rule and an implicit fixed salary promise that must be self-enforcing. Since the agent's rent increases with...
