Data equivalence refers to the extent to which the elements of a research design have the same meaning, and can be applied in the same way, in different cultural contexts. Failure to establish data equivalence in cross-cultural studies may bias empirical results and theoretical inferences. Although several authors have encouraged researchers to ensure high levels of data equivalence, no study has assessed the status of the field in relation to compliance with data equivalence standards. Accordingly, this study examines three aspects of data equivalence (construct equivalence, measurement equivalence, and data collection equivalence) within 167 studies that involve cross-cultural data published in the Journal of International Business Studies, Management International Review, Journal of World Business, Strategic Management Journal and the Academy of Management Journal from 1995 to 2005. The findings indicate that international business researchers report insufficient information in relation to data equivalence issues, thus limiting confidence in the findings of many cross-cultural studies. To enhance future research, a guideline for procedures for researchers to follow and report in establishing data equivalence is offered.

Companies expend vast resources to create product and brand portfolios in the global marketplace. Yet knowledge of the market-based performance implications of various positions in a firm's portfolio architecture is lacking in the literature. To further the understanding of managing brands in the global marketplace, the authors develop a conceptual framework based on the tenets of signaling theory, explore the relationship between global brand architecture and market-based performance, and consider how culture moderates this relationship. The results of the analyses, from a panel data set of 165 automotive brands operating in 65 countries from 2002 to 2008, reveal that global brands perform better in the marketplace than their nonglobal counterparts. Cultural values indeed provide boundary conditions for this relationship, suggesting that alternative strategies for some markets may be advisable.

The purpose of this study is to explore the factors that influence the launch of brands into new markets in a global environment. Although multiple streams of literature exist with respect to the entry of brands into new markets and the diffusion of new brands within and across markets, the process of launching products and brands globally over time has received relatively limited attention. To address this issue, this study incorporates multiple indicators of activities that can contribute to experiential learning relevant for launching brands in a global marketplace. Market uncertainty and experiential learning provide a conceptual foundation for the development of relevant hypotheses, which are tested in the context of the global automotive industry from 1981 to 2004. A discrete time event history analysis with time-varying independent variables is employed to estimate the effects of the independent variables on the probability of a brand being launched in a specific market. The global brand launch observations are extracted from a proprietary dataset containing the global dispersion of automotive brands including 22 countries of origin and 42 countries of brand entry. The sample yields 50,572 spells, derived from 99 companies, 173 brands, and 700 market entries. The results of this study contribute to the literature in a variety of ways. Market attractiveness positively influences the propensity of a brand to be launched into a new market. This supports the idea that potential demand conditions are an important managerial consideration in product introduction decisions. The results reveal significant effects with respect to the role of psychic distance and experiential learning. Brands are reluctant to launch into countries that are culturally and economically less similar to the home market. Yet firms tend to place a lower degree of emphasis on factors of cultural distance when launching brands into larger markets, and global experience enables companies to overcome the uncertainties associated with launching brands into international markets that are economically distant. The results also suggest that companies are more likely to introduce additional brands in markets where they already have a presence. Overall, global dispersion and geographic scope, coupled with local market knowledge facilitate the launch of brands globally. From a managerial perspective, this study suggests companies should focus on acquiring both local and global experience to facilitate the launch of products and brands in the global marketplace.
