Wage disparities and their consequences have long been a topic of economic research. While most papers focus on describing the development of wage differentials over time and seek to identify the reasons for the observed patterns, few attempts have been made to analyze the influence of pay inequality on economic outcomes. A unique and rather large data set from the North American team sports industry is used to address the question how wage disparities affect the performance of professional teams. First, changes in intra‐ and inter‐team wage inequality are documented. Second, the impact of wage inequality on team performance is directly analyzed. Overall, the results differ to a considerable degree between the four major leagues, suggesting that the relative importance of high‐powered incentives and cooperation is different in football and hockey from basketball and baseball.

This paper introduces the Special Issue on competitive versus non‐competitive wage differentials, a collection of papers originally presented at the 79th Conference of the Applied Econometrics Association held in Brussels in May 2002.

The purpose of this paper was to evaluate the impact of some labeling aspects on the consumer intent to purchase ready to drink orange juice and nectar.

The influence of label information on the consumer intent to purchase was evaluated by conjoint analysis using a convenience sample (n=149). A factorial design with four characteristics, price, brand, information about the product and kind of beverage, was used. Three levels were established for brand and product information, and two for price and kind of beverage.

Low price, product information and market leading brand had positive impact. “No preservatives/natural” was the information that most influenced consumer's purchase intent. The ideal label showed the leading brand, low price and information “no preservatives/natural”. These results could be useful for strategic planning of consumer instruction and have important implications for Brazilian orange juice manufactures.

Although the most widely consumed beverages in Brazil are ready to drink orange juice and nectar, it was unexpected that consumers did not know the differences between them and that kind of beverage was not an important factor for the purchase decision.
