The present dissertation is twofold and takes up several issues in two separate and independent articles. In chapter II, the hedging effectiveness of weather index-based insurance with regard to aggregation biases in the underlying risk exposure of aggregated yield time series is presented. The...

In this paper we price a precipitation option based on empirical weather data from Germanyusing different pricing methods, among them the burn analysis, index value simulation anddaily simulation. For that purpose we develop a daily precipitation model. Moreover, a decorrelationanalysis is...

In usual pricing approaches for weather derivatives, forward-looking information such as meteorological weather forecasts is not considered. Thus, important knowledge used by market participants is ignored in theory. By extending a standard model for the daily temperature, this paper allows the...

The question of how the increasing challenges of on-farm risk management - that e.g. result from the global climate change - could be met, has been an important subject of research for a long time. For instance, it has been discussed if index-based insurance are an alternative to classical...

Since the mid-nineties, agricultural economists discuss the suitability of "weather derivatives" as hedging instruments for volumetric risks in agriculture. Contrary to traditional insurance contracts, the payoffs of such derivatives are linked to weather indices (e.g. accumulated rainfall or...

The importance of weather as a production factor in agriculture is well established long time and a significant portion of yield fluctuations is caused by weather risks. Traditionally, farmers have tried to hedge against unfavorable weather using insurance, such as crop insurance. In recent...

Weather-index insurances are innovative risk management instruments that - compared to conventional insurances - cause low administration and regulation costs and are not accompanied by moral hazard or adverse selection problems. Despite these advantages, farmers make little use of weather-index...

Die Bedeutung des Wetters als Risikofaktor in der Landwirtschaft ist seit langem bekannt. Zur Reduzierung wetterbedingter Risiken wurden in den letzten Jahren insbesondere Ertragsausfallversicherungen diskutiert. Ein relativ neues Instrument zur Steuerung des Mengenrisikos stellen sog....
