For European operators of biofuels plants there are not many hedge vehicles available to hedge operational margins. Cross hedges for rapeoil (with the rapeseed futures contract) and RME (with the NYMEX diesel futures contract) could be useful instruments. We use recent developments on threshold...

Mangelhafte Reformen in der Landwirtschaft Kasachstans am Anfang der Transformationsperiode sowie die Finanzkrise 1998 hatten stark negative Auswirkungen auf den Umfang und die Struktur der landwirtschaftlichen Produktion. Wegen der schwierigen finanziellen Lage Anfang bis Ende der 90-ger Jahre...

In einer Studie wurden die volkswirtschaftlichen Kosten verschiedener Produktionsverfahren und Szenarien der Strom- und Wärmeproduktion aus Biogas auf der Basis von Mais und Rindergülle untersucht. Gemessen an alternativen Maßnahmen, verursacht die staatliche Förderung der...

Agricultural bioenergy production faces dynamics such as yield fluctuations, volatile prices, resource competition, new regulation and policy, innovation and climate change. To what extent is bioenergy production able to adapt to changing environments and to overcome critical events? We...

Recently gravity trade models are applied to disaggregated trade data. Here many zeros are characteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood (PPML) is still consistent, the variance covariance matrix however is invalid. Correct economic interpretation...

This paper analyzes co-movements and discusses possible market integration between aggregate food and stock markets in the period of 1990 to 2012. Correlations, price return distributions, cointegration, and Granger-causalities are tested in subsamples on monthly FAO Food Price Index and MSCI...

We use contemporaneous causality tests based on instrumental variables (IV) methods to re-examine causality from Commodity Index Trader positions to agricultural futures prices. A number of recent studies found that no Granger-causal impacts are discernible for agricultural commodity markets....
