| Corn acreage response in Iowa is examined using a time-varying parameter regression model. Separate estimates of the permanent portion of the parameter vector are obtained for each year over the period 1957-82. The estimated elasticities are grouped into program and nonprogram periods. The results indicate corn acreage response is more own-price elastics, and the elasticity is less variable under government acreage control programs than under a nonprogram regime. The assumption of parameter constancy is shown to be inappropriate for modeling Iowa corn acreage response over time. |

| Naïve and adaptive schemes have been used as proxies for price expectations in previous studies of supply response. Those studies contain mixed formulas of futures, support, and lagged prices as alternative formulations for price expectations. This study uses a conditional expected price which combines both market and support prices into one price expectations measure. It defines the total effect of available information on supply response. The results indicate the potential usefulness of formulating expected prices as conditional price expectations in supply response analysis, with support prices being the conditional set. Under the provisions of the 1985 Farm Bill, significant reductions in corn and soybean acreages are in prospect for 1987-90. |
