This paper examines return predictability when the investor is uncertain about the right state variables. A novel feature of the model averaging approach used in this paper is to account for finite-sample bias of the coefficients in the predictive regressions. Drawing on an extensive...

Today, more than 70% of the world's total electricity production is supplied by power plants using conventional fossil fuels. Coal accounts for more than half of the fossil fuel combustion in electricity plants. Future mega trends give reason to believe that electricity demand will double until...

This paper provides an overview of telecommunications regulation in the U.S. and in Europe. For each region the history of telecommunications regulations as well as the current regulatory regime is portrayed. The focus of this overview is on the question of how unbundling regulations in the...

This paper presents and compares several time-series models for returns of broadbased stock indices. These models nest a nonlinear asymmetric GARCH (NGARCH) model as a special case. Some of these models are empirically motivated ad-hoc specifications others are derived from a representative...

This paper documents that standard cross-sectional determinants of firm leverage also apply to the capital structure of large banks in the United States and Europe. We find a remarkable consistency in sign, significance and economic magnitude. Like non-financial firms, banks appear to have...

This paper compares trends in wage inequality in the U.S. and Germany using an approach developed by MaCurdy and Mroz (1995) to separate age, time, and cohort effects. Between 1979 and 2004, wage inequality increased strongly in both the U.S. and Germany but there were various country specific...

Existing literature has confined university technology transfer almost exclusively to formal mechanisms, like patents, licenses or royalty agreements. Relatively little is known about informal technology transfer that is based upon interactions between university scientists and industry...

There is extreme heterogeneity of firms regulated under the European Emissions Trading Scheme (EU ETS) in terms of emissions evels and employed technology. We present a model that shows that behavior of firms under quantity regulation can differ strongly, dependent on the characteristics of the...

Despite the high CO2 emission intensity of fossil and especially coal fired energy production, these energy carriers will play an important role during the coming decades. The case study identifies the main technological trajectories concerning more efficient fossil fuel combustion and explores...

We analyze differences in the pricing of syndicated loans between U.S. and European loans. For credit lines, U.S. borrowers pay significantly higher spreads, but also lower fees, resulting in similar total costs of borrowing in both markets. For term loans, U.S. firms pay significantly higher...
