英文文献摘要：
The paper investigates exogeneity tests between hog prices and sow farrowings and between cattle prices and cattle on feed inventories. The tests, which are useful in constructing dynamic bivariate regressions, suggest that sow farrowings is empirically exogenous with respect to hog price and that cattle price is exogenous with respect to cattle on feed inventories.
