Before 2004 South Africa was the dominant steam coal exporter to the European market. However a new market situation with rising global demand and prices makes room for a new entrant: Russia. The hypothesis investigated in this paper is that the three incumbent dominant firms located in South Africa and Colombia reacted to that new situation by exerting market power and withheld quantities from the ...
The price for a single-family house depends both on the characteristics of the building and on its location. We propose a novel semiparametric method to extract location values from house prices. After splitting house prices into building and land components, location values are estimated with adaptive weight smoothing. The adaptive estimator requires neither strong smoothness assumptions nor local ...
This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an increase in the relative size of more productive firms. We show how the relative importance of these effects, and ...
Im Zuge der von der Bundesregierung eingeleiteten Energiewende wird zunehmend die Frage diskutiert, wie bei einem forcierten Ausbau der erneuerbaren Energien und der dadurch zunehmenden Fluktuation der Stromerzeugung die Versorgungssicherheit gewährleistet werden kann. Zur Diskussion steht die Einführung von Kapazitätsmechanismen zur Ergänzung oder sogar als vollständiger Ersatz klassischer Energy-Only-Märkte. ...
In this paper, we make multi-step forecasts of the monthly growth rates of the prices and rents for flats in 26 largest German cities. Given the small time dimension, the forecasts are done in a panel-data format. In addition, we use panel models that account for spatial dependence between the growth rates of housing prices and rents. Using a quasi out-of-sample forecasting exercise, we find that both ...
Untersuchungen über die Preise auf dem Markt für Wohnimmobilien geben in aller Regel Aufschluss über die Preise für Wohnungen in einer bestimmten Lage oder mit einer bestimmten Beschaffenheit. Das DIW Berlin hat ein Verfahren entwickelt, mit dem die Preise für verschiedenartige Wohnungen zu einer einheitlichen Größe zusammengefasst werden. Damit kann die Preisentwicklung übergreifend etwa für alle ...
In this paper, we suggest to estimate the home rents and prices in German regions/cities using the data from Internet ads offering the housing for rent and sale. Given the richness of information contained in the ads, we are able to construct the quality-adjusted rent and price indices using the hedonic approach. The results can be applied both for investigating the dynamics of rents/prices and for ...
