| Conceptual problems in model specification of beef supply response studies are investigated and a simultaneous equation model is formulated to estimate annual U.S. carcass supply, demand, and inventories of beef. Three basic issues are addressed: (a) disaggregation, (b) simultaneity, and (c) differentiation between current and expected price effects. Empirical results indicate positive supply response of each quality type of steers and heifers, and negative supply response of cows to current own-price changes. The derived aggregate supply elasticity is positive. The effects of grain price changes on beef price, supply and composition are also evaluated. |

| Agriculture department programs in 43 states surveyed offer similar services in regulation, market promotion, and natural resource conservation but are organized differently. Two OLS equations were estimated to explain state agriculture department expenditures as a function of gross farm sales, farm receipts mix, degree of government centralization, the proportion of metropolitan area residents, and tax capacity. A positive relation was found between state agricultural spending and gross farm sales and the percent of fruit/vegetables farm receipts. However, the results cast doubt over the Leviathan thesis of increasing government spending resulting from bureaucratic power. |
