Farm numbers and average farm size in the United States have held about constant since the 1974 Census. but the proportion of mid-sized farms has decreased This pattern follows four decades of a strong trend toward fewer and larger farms Markov analysis IS a standard procedure for projecting...

An empirical model accurately estimates row crop and extensive crop acreage in the North Central region. It shows (a) for each 1-acre increase in diversion, rcw crops decrease 0.62 acre and extensive crops decrease 0.12 acre, and (b) the annual shift to .row crops is diminishing.

This research completes a series of estimates of supply relationships for corn, sorghum, oats, and barley. (See M. E. Ryan and M. E. Abel, "Corn Acreage Response .. .,"Agr. Econ. Res. 24(4); 102-112, Oct. 1972, and "Supply Response of U.S. Sorghum Acreage ...,"Agr. Econ. Res. 25(2); 45-55, April...

A model is described that projects land use patterns under both competitive and profit maximizing conditions. Separable programing is utilized to internalize price effects resulting from project production, and to allow extension of the basic model to include cross-elasticities. An empirical...

A stochastic computer simulation model is used to estimate disaster payments under the Agriculture and Consumer Protection Act of 1973. The model uses a random yield generator and actuarial techniques. Simulated payments under 1976 program parameters and stochastic yields are estimated at $300...

A two-stage sample of airphoto prints and point sampling was used to examine changes in land use patterns in 53 selected counties that had grown rapidly and substantially in population between 1960 and 1970. Point sampling, 20 points per square mile, was used on a sample of airphoto prints...

".. . The concept of property never has been, is not, and never can be of definite content. The paradigm of a Sanskrit verb of a thousand forms could not approach in diversities the phases of that concept in any time and place. . . . Changing culture causes the law to speak with new imperatives,...
