Which Regional Inequality? The Evolution of Rural–Urban and Inland–Coastal Inequality in China from 1983 to 1995

This paper develops a unified empirical framework for describing the relative contribution of rural–urban and inland–coastal inequality to overall regional inequality in China during the 1980's and 1990's. The framework assesses rural–urban and inland–coastal inequalities from the same data set, presents results for a sufficiently long time period to transcend short-term fluctuations, allows for differential price changes, and applies a consistent notion of the contribution to inequality using a decomposition analysis. While the contribution of rural–urban inequality is much higher than that of inland–coastal inequality in terms of levels, the trend is very different. The rural–urban contribution has not changed very much over time, but the inland–coastal contribution has increased by several fold. The paper ends by investigating the role of labor migration in this outcome. J. Comp. Econom., December 1999, 27(4), pp. 686–701.

Sibling brands, multiple objectives, and response to entry: The case of the marion retail coffee market

A new brand entering a market often finds itself in competition with sibling brands (those owned by the same parent company). In a case study of a retail coffee market, the authors examine how these brand relationships might influence the sibling and competitor brands' responses to entry. Using an empirically validated brand-share attraction model, the authors compare the actual responses to entry with the optimal responses under different incumbent objectives. The authors find that the responses by sibling brand are more accommodating than those of unrelated brands whose responses are consistent with the preservation of preentry levels of sales. Thomas S.
