| Taking the price of futures as a proxy for expected price, this article treats acreage planted to soybean, the price of futures, and other variables as jointly dependent. A futures price equation is embedded in a simultaneous equations model along with the consumption demand and acreage response. The model is estimated using both ordinary and three-stage least squares. Estimated price elasticities for consumption demand, demand for stocks, and acreage response equal, respectively, -.5, -1.8, and +.2 (short run) and +.59 (long run). |

| As the result of Uruguay Round negotiations, Korea and Japan established tariff rate quotas (TRQs) for agricultural imports. Both countries allocate the TRQs with various methods that show different fill rates and welfare implications. The state trading enterprises play important roles in TRQ administration in both countries. The TRQs contributed to increased imports. However, the transparency and commercial consideration in administrating the TRQs remain a concern and the access for some commodities seems to be less open than would be the case if quota amounts were made available on a purely commercial basis. |

| A two-stage approach is used to estimate sensitivity of corn, wheat, and soybean yields to changes in prices and land idled. Estimated elasticity of demand for fertilizer per acre with respect to expected output price equals 0.47, 0.10, and 0.82 for corn, wheat, and soybeans. Upper estimates of the elasticity of yield with respect to fertilizer equals +0.58, +0.29, and +0.16 for corn, wheat, and soybeans. Yields are found to be quite insensitive to price changes. Fertilizer demands and yields are insensitive to land idled under farm programs. |
