Testing for Speculative Bubbles in Agricultural Commodity Prices: A Regime Switching Approach AgEcon
Liu, Xiaoliang; Filler, Gunther; Odening, Martin.
The sharp increase in agricultural commodity prices in 2008 and in 2011 has triggered an intensive debate on the causes for these price booms. Speculative bubbles have been quoted as one factor among others for the price peaks. Against this background, our paper contributes to this discussion by implementing a novel test procedure for speculative bubbles which has been suggested in the stock market literature. We use a regime switching regression model to test the hypothesis that agricultural prices are driven by periodically collapsing bubbles. The analysis is conducted for wheat, which is one of the most important crops worldwide. Our results show that the data do not support this particular bubbles hypothesis.

On the Systemic Nature of Weather Risk AgEcon
Xu, Wei; Filler, Gunther; Odening, Martin; Okhrin, Ostap.
Systemic weather risk is a major obstacle for the formation of private (nonsubsidized) crop insurance. This paper explores the possibility of spatial diversification of insurance by estimating the joint occurrence of unfavorable weather conditions in different locations. For that purpose copula methods are employed that allow an adequate description of stochastic dependencies between multivariate random variables. The estimation procedure is applied to weather data in Germany. Our results indicate that indemnity payments based on temperature as well as on cumulative rainfall show strong stochastic dependence even at a national scale. Thus the possibility to reduce risk exposure by increasing the trading area of the insurance is limited. Irrespective of...

EFFIZIENZ UND RENTABILITÄT VON BIOGASANLAGEN AgEcon
Odening, Martin; Filler, Gunther.
Die Verbreitung von Technologien zur Biogaserzeugung hängt maßgeblich von deren einzelbetrieblicher Wirtschaftlichkeit ab. Der vorliegende Beitrag bestimmt die technische und die ökonomische Effizienz sowie die Rentabilität von Biogasanlagen auf der Basis empirischer Daten, die aus einer Befragung des KTBL hervorgehen. Die Effizienzmessung erfolgt mittels Data Envelopment Analyse (DEA). Es zeigt sich, dass die Effizienz der untersuchten Anlagen eine große Variabilität aufweist. Dies deutet darauf hin, dass die Produktionstechnik nicht in allen Betrieben voll beherrscht wird. Entscheidend für die Effizienz von Biogasanlagen ist weniger deren Größe als vielmehr eine gute Auslastung. Mit Blick auf die Rentabilität stellen die Kosten für die Bereitstellung der...
