Optimization has been recognized as a powerful tool in teaching and research for a long time. In spite of its well known problem solving capacity, some methodological obstacles have persisted over the years. The main problem is that stochastic variables and their correlations cannot be...

Investment decisions are, as a rule, characterized by uncertainty, irreversibility and flexibility. Simple net present value calculations will not account for these features. In many situations even flexible investment planning with decision trees, which represents the most advanced method of...

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...

In this paper we examine whether there is room for improvement in farm program decisions through the integration of formal mathematical optimisation into the planning process. Probing the potential for improvement, we investigate the cases of four Brandenburg cash crop farms over the last six...

Die Effizienzanalyse mit Hilfe der Data-Envelopment-Analyse (DEA) stellt ein weit verbreitetes Verfahren zur vergleichenden Einschätzung der empirischen Performanz von Entscheidungseinheiten (z.B. Unternehmen) dar. Angesichts „boomender“ Anwendungen auf eine Vielzahl...

The objective of this paper is to explore the potential of the real options approach for analyzing farmers’ choice to switch from conventional to organic farming. Understanding the determinants of this decision is relevant in particular for agricultural policy makers when predicting the...

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...

Food risks may be caused by moral hazard, i.e. by opportunistic behaviour of upstream sellers who exploit the fact that many food product qualities remain uncertain to downstream buyers in the course of conventional market transactions (credence qualities). Due to this lack of market...

The objective of this paper is to investigate the performance of different Value-at-Risk (VaR) models in the context of risk assessment in hog production. The paper starts with a description of traditional VaR models, i.e. Variance-Covariance-Method (VCM) and Historical Simulation (HS). We...
