摘要：This report describes the economics and data structure of the HORTUS partial equilibrium supply and demand model developed at LEI. HORTUS can be used to simulate the effects of policy changes and exogenous changes in costs, production and consumer trends on the production, trade and consumption patterns of vegetables and fruits in the Netherlands and other European countries. The report demonstrates the use and working of the model by means of two simulations: (1) a general reduction of import tariffs in the EU and (2) a rise in heating gas prices in the Netherlands.
