The optimal provision of agri-environmental externalities is studied in a model of endogenous input use and land allocation augmented by their effects on biodiversity, landscape diversity and nutrient runoffs. Whereas biodiversity and landscape diversity are public good aspects of agriculture,...

We examine the potential of bioenergy crops to offset greenhouse gas emissions from fossil fuels, assuming homogeneous agricultural land and distance-dependent transport costs. Variable transport costs define the socially and privately optimal extensive margin of the bioenergy crop production...

We assess theoretically and empirically the private profitability and social desirability of conventional tillage and no-till when crop yields, production costs and nutrient and herbicide runoff damages are taken into account. Based on Finnish experimental data, no-till provides higher social...
