Between 1973 and 1983, the portion of eggs produced under contracts or vertical integration increased from an estimated 62 percent to 88 percent. This article adduces and tests two hypotheses to explain the effects of the increased vertical control on industry performance. The results suggest that deficiencies in the market mechanism rather than anticompetitive factors are responsible for the increased vertical control. The farm-retail price spread for eggs between 1973 and 1983 declined 42 percent in real terms; about 58 percent of this decline is estimated to be attributable to increased vertical control.

This classroom experiment allows students to explore pricing strategies available to the monopolist. Students are given full information about their costs but know nothing about demand except that it is simulated by the instructor. They submit their price-asked and quantity-offered records on one day and receive the quantity-sold response from the instructor on the next day, continuing this routine until they discover the profit-maximizing price and quantity. One of the objectives is to demonstrate that search strategies based on economic principles (MC=MR) can be more efficient than trial-and-error.

Generic advertising is used by fish producers to accelerate demand growth or to alleviate temporary surpluses. Whether this cooperative promotional venture is profitable depends on a number of factors including industry supply response. A rent-dissipation model applied to the U.S. catfish industry suggests the quasi-rents generated by increased advertising are more than sufficient to cover incremental costs over any reasonable time horizon.

Abstract This study analysed the benefits and costs of three airlift aeration regimes — continuous (24 hr), partial (9 hr/night plus emergencies), and no aeration — for channel catfish in cages. Data from four field studies included four dependent variables based on size at harvest, and six independent variables. Four regression models were fit with a modified Cobb‐Douglas production function in a Seemingly Unrelated Regression system. Yield projections from the production function were then used in a stochastic economic model with prices and variable costs expressed as triangular distributions. Results indicated that none of the aeration methods was preferred to the others by either first‐ or second‐degree stochastic dominance criteria, although partial aeration was the risk‐neutral choice. A power analysis was used to demonstrate that an impractical number of replicates would be needed to detect a difference between partial and continuous aeration that was both economically and statistically significant.

Publisher Summary This chapter reviews the economic benefits and costs of Bt cotton, with detailed analysis of rent creation and distribution in 1996 and 1997, by using survey data. It provides the preliminary surplus estimates for Bt cotton in 1998 and then compares the preliminary results from 1998 both to estimates from 1996, and to the estimate from the 1997 planting season presented by Falck et al . The results indicate that farmers and the innovators share almost equally rents created by adopting Bt cotton. Farmers gain 43% of total rents whereas the innovators gain 47% of total rents. The regions with low adoption such as California and Missouri lost because farmers suffered a reduction in cotton lint prices without having the benefits of the technology. Finally, it discusses some of the implications of the estimated distribution of rents on farmer and society welfare and impacts of biotechnology varieties in the US and abroad. A sensitivity analysis is performed to evaluate results by reducing the yield and/or cost change assumptions by half. In the worst case scenario, where yield increases and cost reductions were reduced by 50%, farmers still were able to capture 21% of the total rents, whereas the innovators gained 74% of total rents. Farmers share almost equally with the innovators the rents created by the technology even when a monopolistic structure for the input market is assumed.
