✦ Synopsis

The paper analyzes, based on a land classi"cation system, the optimal management of negative production externalities while taking into account the intertemporal and spatial aspects of the problem. To incorporate both aspects simultaneously, a two-stage modeling approach is proposed where the solution of the spatial problem ("rst stage) is optimized over time (second stage). As a result, it is possible to relate long-run and short-run supply and input demand functions. Attention is given to runo!s from agricultural land leading to the contamination of a water body, in particular, the one of phosphorus and the eutrophication of lakes. The employment of a land classi"cation system supports a full-information approach and allows to address the optimal management of mineral fertilizer and manure based on zonal taxes, zonal permits, and zonal standards which all vary over time.
