Introduction of biotechnologically modified soybeans will have significant impacts on the US soybean and associated industries. However, technical trade-offs of yield and quality attributes make it difficult to determine which modifications offer the highest potential pay-off and warrant the...

This study develops an empirical framework to estimate quality-adjusted price elasticities from cross-sectional data. The new approach shows the importance of properly adjusting for quality variation in both prices and quantities in demand analysis. When quality adjustment is concerned only with...

This study develops a varying-parameter advertising model specifying advertising parameters as a function of advertising strategies and market environments to explain the varying nature of the advertising responses. This model allows researchers to examine the sources of change in advertising...

This article focuses on two important issues faced by researchers working on choice experiments: how to find the optimal number of alternatives in each choice set and the number of choice sets in each survey. The authors first develop survey instruments with different numbers of choice sets and...

This study develops an analytical framework to examine the impact of generic advertising on brand advertising with alternative assumptions on demand changes (shift-up and rotation), product differentiation, market concentration, and relationship between commodity and brand advertising programs....

Consistent two-step censored estimation is applied to household demand equations for disaggregated milk and cheese products. The long-run advertising elasticity for total milk was positive, largely due to low fat milk; however the elasticity for cheese was not significant, and only shredded...
