Building relationship innovation in global collaborative partnerships: big data analytics and traditional organizational powers

This study examines how relationship innovation can be developed in global collaborative partnerships (alliances, joint ventures, mergers, and acquisitions). The recently emerging theory of big data analytics linked with traditional organizational powers has attracted a growing interest, but surprisingly little research has been devoted to this important and complex topic. Therefore, after developing the theoretical foundations, our study empirically quantifies the links between the theoretical constructs based on the data collected from chief executive officers, managing directors, and heads of departments who work in contemporary global data‐and‐information driven collaborative partnerships. The results from structural equation modeling indicate that the relationship innovation depends on the power of big data analytics and non‐mediated powers (NMP, expert and referent). The power of big data analytics also mediates the correlation between NMP and relationship innovation. However, mediated powers (coercive and manipulative) negatively affect the power of big data analytics and relationship innovation. The interaction effects further depict that analytically powered partnerships have better relationship innovation compared with those which focus less on the analytical power. Consequently, the contributions of this study provide a deeper understanding of mechanisms of how modern collaborative partnerships can use big data analytics and traditional organizational powers to co‐create relationship innovation.     

Balancing social and political strategies in emerging markets: Evidence from India

This article explores the substitution and complementary effects between political and social strategies on firm performance in the context of an emerging market (EM). Using in‐depth, historical case‐study approach, the article investigates how companies integrate political and social resources in this market. Corporate performance includes traditional measures, such as accounting performance and nonfinancial measures like the ease of doing business. The study finds that social strategies are stronger enablers of firm long‐term performance than political strategies. The latter have a short‐term impact on performance, but their success over time is limited. The main drawback of reliance on political resources in EMs is the lack of political stability, fragmented polity, and weak political coalitions. We identify rather limited evidence of firms using these two strategies as complements. Thus, we suggest that firms should employ both these strategies in the EM.     

Price competitiveness of tourism packages to Australia: Beyond the “Big Mac” index

One issue facing any country or region concerns its price competitiveness as a package tour destination. One method of measuring this is to use what in other contexts has been referred to as the Big Mac approach. The “Big Mac” is a simple product with ingredients in fixed proportions, whereas the tourism product is a very complex one comprising different components depending on tourist expenditure patterns. There is no equivalent tourism product offered across countries, as the nature of the product is tailored to the origin market, expenditure levels and the length of the trip involved. The key issue is that of how to standardize the products being compared, so as to determine their relative price competitiveness. A method of constructing price competitiveness indexes, developed by the authors, can be applied to develop measures of the price competitiveness of different tour packages. This paper has three aims: To set down the essence of the preferred approach to measuring price competitiveness, noting its advantages and limitations; to employ this approach to construct price competitiveness indexes for package tours to Australia from Japan and the USA; and to indicate areas for farther research into the price competitiveness of package tourism worldwide.

THE EFFECT OF INSTITUTIONAL INTEREST ON THE INFORMATION CONTENT OF DIVIDEND-CHANGE ANNOUNCEMENTS

We test the hypothesis that the information content of dividend-change announcements, as reflected in stock prices, is directly related to the degree of pre-announcement information asymmetry in the stock. The dividend-change announcements include initiations, large increases, large decreases, and omissions. Information asymmetry is proxied by the proportion of stock held by institutions. Consistent with the hypothesis, we document a significantly positive relation between the absolute values of the announcement-period excess returns and the degree of pre-announcement information asymmetry in the stock. This finding appears to hold for all types of dividend changes except dividend omissions.     

Fiscal Decentralization and Poverty Alleviation in a Transitional Economy: The Case of Viet Nam

Intergovernmental fiscal arrangements may play an important role in ameliorating poverty in many countries. Successful poverty alleviation generally requires both ‘capacity improving’ and ‘safety net’ policies, and both types of policies may, to some extent, be implemented through, or affected by, intergovernmental transfers. From this perspective, we analyse the efficacy of intergovernmental fiscal arrangements in poverty alleviation in a transitional economy, Viet Nam. We argue that both general and specific transfers are needed for this purpose: the former to enable all provinces to provide a given basket of public services at a given tax-price by offsetting their revenue and cost disabilities and the latter to ensure that minimum levels of those public services provided by lower levels of government are targeted to the poor throughout the country.     

May’s theorem in an infinite setting

We generalize May’s theorem to an infinite setting, preserving the elementary character of the original theorem. We define voting scenarios and generalized voting scenarios, and prove appropriate versions of May’s theorem. The case of generalized voting scenarios specialized to a countably infinite set of voters and the collections of all coalitions that have asymptotic density, shows that majority rule is the only aggregation rule that satisfies neutrality, irrelevance of null coalitions, anonymity, and positive responsiveness.

PRICE HETEROGENEITY AND "REAL" INEQUALITY: A CASE STUDY OF PRICES AND POVERTY IN RURAL SOUTH INDIA

This paper, based upon a case-study of three Indian villages, studies whether households within the same market pay different prices for identical goods. It is found that not only are unit prices for food heterogeneous, but that the poor pay more for the same goods than the rich. This is because liquidity constraints force poorer households to purchase goods in small quantities and consequently subject them to quantity premiums. Household specific index numbers are used to adjust nominal incomes to real values and it is found that Gini coefficients of real incomes are between 12 percent to 23 percent greater than the Gim for nominal incomes. An econometric analysis of the determinants of prices shows that incomes are negatively correlated with prices, as is family size, but that the amount of land owned shows a positive relationship.
