The End of Cheap Coal? A Techno-Economic Analysis until 2030 Using the COALMOD-World Model

Questions about the future availability of inexpensive coal supplies are rising. In this paper a numerical model is developed to investigate the evolution of the international market for steam coal used for electricity generation. The "COALMOD-World" model is an equilibrium model that computes future trade flows, infrastructure investments and prices until 2030. The model includes the major domestic ...

What about Coal? Interactions between Climate Policies and the Global Steam Coal Market until 2030

Because of economic growth and a strong increase in global energy demand the demand for fossil fuels and therefore also greenhouse gas emissions are increasing, although climate policy should lead to the opposite effect. The coal market is of special relevance as coal is available in many countries and often the first choice to meet energy demand. In this paper we assess possible interactions between ...

Das Sozio-oekonomische Panel (SOEP)

Das Sozio-oekonomische Panel (SOEP) ist die derzeit größte und am längsten laufende multidisziplinäre Langzeitstudie in Deutschland. Die erste Erhebungswelle fand 1984 in Westdeutschland statt; die Studie wurde dann im Juni 1990 auch auf Ostdeutschland ausgedehnt. Für das SOEP werden seit 1984 in Westdeutschland und seit 1990 in Ostdeutschland jedes Jahr mehr als 20.000 Menschen in über 10.000 Haushalten ...

Evaluating Continuous Training Programmes by Using the Generalized Propensity Score

The paper assesses the heterogeneity of treatment effects arising from variation in the duration of training. We use German administrative data that have the extraordinary feature that the amount of treatment varies continuously from 10 days to 395 days (i.e. 13 months). This feature allows us to estimate a continuous dose-response function that relates each value of the dose, i.e. days of training, ...

Transmission Investment in the Peruvian Electricity Market: Theory and Applications

This research presents an application of the mechanism in Hogan et al. (2010) (HRV) to promote electricity transmission network expansion in the Peruvian electricity transmission system known as SEIN (Sistema Eléctrico Interconectado Nacional). The HRV mechanism combines the merchant and regulatory approaches to promote investment into transmission grids. This mechanism gives incentives for efficient ...

The Private Equity Premium Puzzle Revisited: New Evidence on the Role of Heterogeneous Risk Attitudes

The empirical finding that entrepreneurs invest a large share of their wealth in their own firms, despite comparably low returns and high risk, has become known as the private equity premium puzzle. This paper provides evidence supporting the hypothesis that lower risk-aversion of entrepreneurs, and thus not necessarily credit constraints, may explain this puzzle. The analysis is based on a representative ...

The Political Economy of the German Länder Deficits: Weak Governments Meet Strong Finance Ministers

We analyse the deficits of the German Länder (regional states) for the period 1960 to 2005 and test a number of hypotheses derived from the literature on the political economy of public deficits. We find evidence for the weak government hypothesis, that is, coalition governments issue significantly more debt than single party governments - a result that is typically explained by the common pool problem. ...

Estimating Level Effects in Diffusion of a New Technology: Barcode Scanning at the Checkout Counter

Cross-country or cross-industry studies of technology diffusion typically estimate how independent factors affect diffusion speed or timing, often based on a two-stage approach. In many applications, however, countries (industries) differ most in the saturation level of diffusion. In a single-stage econometric approach to a standard diffusion model, we therefore estimate how the saturation level covaries ...

Modeling Storage and Demand Management in Power Distribution Grids

Storage devices and demand control may constitute beneficial tools to optimize electricity generation with a large share of intermittent resources through inter-temporal substitution of load. This paper quantifies the related cost reductions in a simulation model of a simplified stylized medium-voltage grid (10 kV) under uncertain demand and wind output. Benders Decomposition Method is applied to create ...
