ACREAGE RESPONSE UNDER FARM PROGRAMS FOR MAJOR SOUTHEASTERN FIELD CROPS AgEcon
Duffy, Patricia A.; Shalishali, Kasazi; Kinnucan, Henry W..
An expected utility model that includes output price and yield uncertainty was used to estimate cotton, corn, and soybean acreage response equations for the Southeast. The model appeared to fit the soybean and corn data well, resulting in own-price elasticity estimates of 0.317 for corn and 0.727 for soybeans. When applied to cotton acreage, however, the model did not yield satisfactory results. When elasticity was allowed to change over time, however, statistical results for the cotton equation improved, yielding an own-price elasticity of 0.915 at data means.

Assessing Time-Varying Oligopoly and Oligopsony Power in the U.S. Paper Industry AgEcon
Mei, Bin; Sun, Changyou.
The U.S. paper industry has become increasingly concentrated and therefore been suspected of imperfect competition. In this study, the new empirical industrial organization approach is employed to measure the degree of oligopoly and oligopsony power in the U.S. paper industry simultaneously. The model is estimated by iterative three-stage least squares using annual data from 1955 to 2003. The results reveal that there has been significant oligopoly and oligopsony power in the U.S. paper industry, and the oligopoly power has been consistently lower than the oligopsony power.

Determinants of Temporal Variations in Advertising Effectiveness AgEcon
Chung, Chanjin; Kaiser, Harry M..
This article develops a varying-parameter advertising model which specifies advertising parameters as a function of variables representing advertising strategies and market environments to explain the varying nature of the advertising responses. Unlike prior models, this model allows researchers to examine the sources of change in advertising effectiveness over time. The model is applied to the New York City fluid milk market for the period from January 1986 through June 1995. Results indicate that advertising strategies and market environments play important roles in determining advertising effectiveness. Particularly, demographic factors were more important than economic factors. The results also suggest that when a market is in an unfavorable or...

Generic Advertising Wearout: the Case of the New York City Fluid Milk Campaign AgEcon
Reberte, J. Carlos; Kaiser, Harry M.; Lenz, John E.; Forker, Olan D..
Thispaperexaminestwo majorgenericfluidmilkadvertising campaigns in New York City during the 1986-92 period Estimates from a time-varying parameter model show that the evolution ofthe impact ofgeneric advertising on fluid milk sales over each campaign followed a bell-shaped pattern. Results also show that the first campaign was effectivefor twice aslongasthesecondcampaignandthat it had a higher peak and average advertising elasticity. These findings may reflect long-term generic milk advertising wearout in the New York City market.
