Previous applications of the inter‐temporal quadratic adjustment cost model in agriculture have failed to consider information gained from pre‐testing in choosing an appropriate specification for dynamic demand of quasi‐fixed inputs. A test strategy is outlined taking account of this information in order to consistently estimate adjustment cost and discount rate parameters. Canadian agricultural data are used in the empirical analysis. Test results suggest that the intertemporal quadratic adjustment cost model is inappropriate for modeling dynamic demand for land, labor and machinery.
