Natural gas plays an important role in the future development of electricity markets as it is the least emission intensive fossil generation option while additionally providing the needed flexibility in plant operation to deal with intermittent renewable generation. As both the electricity and...

In recent contributions, Weizs cker (2014) and Summers (2014) maintain that mature economies accumulate too much capital. They suggest large and lasting public deficits as a remedy. This paper argues that overaccumulation cannot occur in an economy with land. It presents novel data of aggregate...

This paper analyzes innovation races in a moral hazard setting. I develop a model where two competing entrepreneurs, financed by a single venture capitalist, work independently on the same project. The venture capitalist cannot observe the allocation of funds she provides, which creates a moral...

We present a duopoly model of strategic capital accumulation in continuous time with uncertainty, such that investment takes the form of singular control. Spot competition is of Cournot type. For this model there exists a parameterized and Pareto-rankable family of Markov perfect equiblibria in...

Real life applications of Yardstick Regulation frequently refer to historical cost data. While Yardstick Regulation cuts the link between fi rms own costs and prices firms may charge in a static setting, it does not in a dynamic setting where historical cost data is used. A fi rm can influence...

Liberalized electricity markets are characterized by a fluctuating price-inelastic demand, non-storable electricity and often show substantial market shares held by one or few incumbent firms. These characteristics have led to a controversial discussion concerning the need for and the design of...

The aim of this paper is to give deeper insights into the impact of regulatory reforms and privatization on R&D spending of electricity utilities. Building on a panel data set including the biggest European utilities from eight EU-countries over a period from 1985 until 2010, we find a strong...

This article presents an electricity dispatch model with endogenous electricity generation capacity expansion for Germany over the horizon 2035. The target is to quantify how fuel price uncertainty impacts investment incentives of thermal power plants. Results point to ndings which are in line...

We estimate the causal impact of the EU Emissions Trading Scheme on manufacturing firms using comprehensive panel data from the German production census. Semiparametric matching estimators yield robust evidence that the policy caused treated firms to abate one fifth of their CO2 emissions...

We compare, based on German data, the income of self-employed individuals with and without employees with the income of dependently employed individuals. Our results show that self-employed with employees tend to earn significantly higher incomes than their salaried counterparts, while with the...
