We develop a Ricardian framework with heterogeneous land quality to analyse the effects of agricultural and agri-environmental support policies on land allocation decisions and land prices. Four agri-environmental policy instruments are considered: a uniform area payment, a quality-dependent area payment, a mandatory buffer strip policy and a voluntary buffer strip payment. We also analyse how general tax and monetary policies may affect agricultural land prices. The theoretical framework is illustrated by an empirical model applied to Finnish agriculture. The empirical model shows that macroeconomic factors, such as general tax and monetary policies, may exert a greater impact on land prices than some minor fine-tuning in agrienvironmental policies.
