U.S. agricultural crop and livestock relationships are examined in the context of both duality and time-series econometrics. Based on time-series test results, cointegrated models are estimated. Traditional models generally overestimated the precision of statistical relationships and gave a...

Results of time series tests (including unit root and deterministic and stochastic cointegration tests) imply that a mixture of differenced and cointegrated model specifications are warranted for econometric models of Mexican agricultural supplies and input demands. Test results are sensitive to...
