This paper applies the Dutch Regionalized Agricultural Model (DRAM) to analyze the effects of Dutch manure and nutrients policies of 2004 for the Dutch agricultural sector and economy as compared to a base of 1996. DRAM can be characterized as a regionalised, environmental, partial equilibrium, mathematical programming model of Dutch agriculture. The model combines the technical detail, including technology options available to farmers in different regions of the Netherlands, of mathematical programming farm models with some market effects at agricultural industry level e.g. land and manure markets. Moreover the mathematical programming model is linked to a mixed input-output model to analyze economy wide effects of changes in Dutch agriculture. A special feature of DRAM is the explicit modeling of manure markets. It is found that through increased manure prices, manure policies specially affects production and profits in the beef and pigs and poultry sectors.
