| This study estimates a hedonic price equation to assess consumers' willingness-to-pay for reduction in pesticide residues in fifteen fruits and vegetables. A unique feature of the study is its employment of the FDA's Total Diet Study data which attempts to measure actual pesticide ingestion by the American public in table-ready or prepared foods. The results indicate that consumers would be willing to pay approximately $.08 per pound to reduce pesticeds by one part per million in the prepared fruits and vegetables that they consume. |

| The market impacts of generic dairy advertising are assessed using an industry model which encompasses supply and demand conditions at the retail, wholesale, and farm levels, and government intervention under the dairy price support program. The estimated model is used to simulate price and quantity values for four advertising scenarios: (1) no advertising, (2) historical fluid advertising, (3) historical manufactured advertising, and (4) historical fluid and manufactured advertising. Compared to previous studies, the dairy-industry model provides additional insights into the way generic dairy advertising influences prices and quantities at the retail, wholesale, and farm levels. |

| The U.S. pork sector is evolving from an industry of small, independent firms vertically linked by spot markets to one of substantially larger firms vertically connected through contractual agreements and integration. Potential benefits to this tighter vertical arrangement include lower consumer pork prices, although the true nature of this benefit is still under debate. At the same time, there is concern of market foreclosure because highly vertically integrated industry may prevent independent hog producers from having access to open markets in which to sell their output. Boehlje underscores the need for empirical answers to questions related to the above structural change in the pork industry. The objective of this paper is to estimate... |

| As the U.S. hog production sector becomes ever more specialized, the importance of capital inputs has heightened. Given that it is costly to adjust the capital stock and that the associated adjustment cost function may exhibit cost asymmetries between investment and disinvestment, profit-maximizing producers may find themselves trapped in a situation where it is neither profitable investing nor worthwhile disinvesting. This article addresses two issues related to the employment of quasi-fixed input in the U.S. hog production sector: does an inaction or sluggish regime exist in the demand for quasi-fixed input, and, if so, to what extent has this impeded adjustment in quasi-fixed input stock and, hence, hog output supply toward the long-term equilibrium... |

| The purpose of this paper is to investigate the threshold effect of the U.S. generic fluid milk and cheese advertising programs. A threshold delineates the level of advertising intensity that has to be met to generate a specific level of sales effect. Given that promotional organizations face budget constraints, it is of particular interest to ascertain if there exists a minimum threshold that an advertising campaign has to overcome to yield a non-trivial sales effect. To the best of our knowledge, there is no study focusing on the threshold effects of generic advertising of agricultural products. The estimation results confirm that, for both fluid milk and cheese advertisings, there exist three thresholds which partition the quarterly observations between... |

| The audience response system (ARS) has increasingly been used to engage students by eliciting and analyzing responses to questions posed by instructors. The authors discuss how they used the system to facilitate pit market trading in a microeconomics class, report the efficacy of the approach and provide suggestions extending the use of ARS to other experiments. Using the ARS to facilitate active learning by engaging students in economics experiments has pedagogical advantages over both the labor-intensive approach of pencil-and-paper and the capital-intensive route of relying on networked or on-line computer labs which oftentimes preclude or restrict face-to-face student interactions. Thus, the new method represents an added advantage on top of such... |

| The authors discuss how they used the audience response system (ARS) to facilitate pit market trading in an applied microeconomics class and report the efficacy of the approach. Using the ARS to facilitate active learning by engaging students in economics experiments has pedagogical advantages over both the labor-intensive approach of pencil-and-paper and the capital-intensive route of relying on networked or on-line computer labs which oftentimes preclude or restrict face-to-face student interactions. Thus, the new method of conducting experiments represents an added advantage on top of such conventional functions as taking attendance and administering quizzes of this increasingly popular classroom technology. |

| This paper expands the contributions of Goodwin and Holt (AJAE, 1999) and Goodwin and Harper (J. of Ag. and Appl. Econ., 2000), GHH henceforth, who analyze retail-wholesale-farm price transmissions in the U.S. beef and pork industries using weekly data. First, in light of advancements in unit root tests, we re-examine in a more comprehensive manner GHH’s conclusion that the weekly U.S. cattle/beef and hog/pork price series are nonstationary. The conventional augmented Dickey-Fuller test that GHH adopt has low power in discriminating against the unit root null because it does not entertain the possibility of a structure break in the deterministic trend function. Second, we examine more closely the estimation procedure surrounding the long run price... |

| This paper examines the impact of PST on the optimal production/marketing decisions of a grow-finish hog farm operation. The analysis evaluates PST from three angles: the feed efficiency effect, the leaner meat price effect, and the aggregate-supply-induced price effect. When limited to the feed efficiency effect only, the primary response to the new technology is to increase the animal turnover rate of the operation. When the leaner meat price effect is also included, marketing weight increases while turnover rate remains relatively unchanged. Additionally, if the increased aggregate supply depressed the market price by more than 10%, the benefits from improved feed efficiency and learner meat will be completely dissipated. Aggregate price... |

| The degree of market power exercised by fluid and manufactured processors in the U.S. dairy industry is estimated. Appelbaum's quantity-setting conjectural variation approach is cast into a switching regime framework to account for the two market regimes created by the existence of the dairy price support program: (a) government supported regime (market price is at the support price) and (b) market equilibrium regime (market price is above the support price). The model is also used to test whether government price intervention has a pro-competitive to anti-competitive influence on market conduct. |

| The extent to which Latin America can pull itself out of persistent poverty in the foreseeable future depends, in an important manner, on how successful the region will be in achieving sustainable growth in its rural economies. A good strategy for sustainable growth in rural Latin America is to make sure that the market works for the poor. The purpose of this paper is twofold. First, it is to lay out some of the issues important to the successful functioning of the key markets in rural Latin America, including labor market, financial market, land market, and agricultural factor and product markets. Second, it is to present policy suggestions regarding how to ensure that the market works for the rural poor. While governments should continue their... |
