Granger-causality tests and Sims' VAR technique were used to analyze the impact of macrovariables on farm output and prices in the U.S. for the period 1934-1987. Granger-causality tests show one-way causality from the macrovariables to the farm sector variables, and this is supported by impulse response functions from a VAR model. Money and interest rate effects on agricultural prices and output are apparent in the data.
