This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws...

Die starke Abhängigkeit von exogen determinierten Zuständen der Welt (Wetter, Krankheiten, Schädlinge etc.) ist konstituierendes Element der meisten landwirtschaftlichen Produktionsprozesse. Während diese Zustandsabhängigkeit auf der einen Seite eine Unsicherheitssituation entstehen lässt,...

This paper serves to document the REPA Forest Trade Model – a global model of forest trade that consists of ten products across two horizontal layers in a vertical chain. The model includes 20 regions: Five Canadian regions (Atlantic Canada, Central Canada, Alberta, BC Interior and BC Coast),...

In this paper, we analyze the potential impact on producers’ land-use decisions in moving from support payments based on entitlements to a single farm payment (SFP). Further, we then consider a single farm payment with a greening component as part of the 2013 CAP reform. Using data for...

The U.S. Energy Independence and Security Act of 2007 mandates the production of 16 billion gallons of cellulosic biofuels by 2022. Desirable feedstock properties, biomass to biofuel conversion rate, and investment required in plant and equipment differs depending on which of several competing...

This paper proposes and applies an innovative estimation approach for farm group programming models using Generalised Maximum Entropy. The proposed set-up simultaneously determines calibrating cost function parameters and input allocations to production activities. The methodology is applied to...
