This study develops an econometric acreage response model for wheat in the Pacific Northwest (Oregon, Washington, and Idaho) and tests several alternative specifications of risk and their effects on wheat acreage response. Results indicate that the existence of a significant relationship between risk and wheat acreage response depends on the...
This study compares and evaluates wheat acreage responses among production systems in Oregon and Washington and between this region and estimated national average wheat acreage response. Oregon and Washington are disaggregated into five regions each on the basis of general similarity in soil, climate, substitute crops and production structures. Regional...
Parameters of an econometric acreage response function were estimated for barley in the Northwest using pooled time-series and cross sectional data. Barley acreage was found to be significantly affected by the price of barley, the price of wheat and wheat acreage (a proxy for the "cross-planting" substitution component of government...
