The role of seeding in multi-market entry

Firms introducing new products into multi-markets often face the dilemma of how to dynamically allocate their marketing resources during penetration. The aim of this study is to examine which responsive allocation strategy is more effective for these firms. We explore three major resource allocation strategies: uniform strategy, in which the firm distributes the marketing efforts evenly among its regions regardless of market development; support-the-strong strategy, under which the firm invests its efforts proportional to the number of adopters in that region (at least up to a certain market coverage); and support-the-weak strategy, in which the firm invests its efforts proportional to the remaining market potential.Using both formal analysis and complex systems simulations, we find that strategies that disperse marketing efforts, such as support-the-weak and uniform strategies, are generally superior to support-the-strong strategy. Not only is this finding surprisingly robust to market conditions and variations on these strategies, but it also runs counter to conventional wisdom prevailing in international marketing. The conditions under which support-the-strong policy might become more effective include: (a) fixed entry or operation costs above a certain level; and (b) substantial variance between regions in responsiveness to marketing efforts. However, variance in intrinsic innovativeness between regions does not imply the superiority of support-the-strong strategy.     

Design and Implementation of Business Objects for Automated Business Negotiations

In recent years, there has been increasing interest in the specification, generation and exchange of business objects in the context of electronic commerce. Common business objects have been defined for product catalogs, purchase orders and other business entities. However, no business objects have been defined and implemented for supporting automated business negotiations even though business negotiation is very much an integral part of business activities. In this work, we have designed and implemented a set of business negotiation objects for supporting the bargaining type of business negotiations. These objects define the operations and information contents needed for negotiation parties to express their requirements and constraints during a bargaining process. They correspond to a set of negotiation primitives, which is a superset of the negotiation-related primitives defined in two popular languages: ACL and COOL. The implementation of these objects is patterned after the business object documents in the XML format proposed by the Open Applications Group, thus conforming to the established standard. The incorporation of several types of constraint specifications in these business negotiation objects provides the negotiation parties and the negotiation servers that represent them much expressive power in specifying callforproposals and proposals. Two synchronization problems and their solutions associated with the withdrawal and modification of negotiation proposals are addressed and presented in this paper. The use of these business negotiation objects in a bilateral bargaining protocol is also presented. We have validated the utility of these objects in an integrated network environment, which consists of two replicated negotiation servers, two commercial products, and some other university research systems that form a supply chain.     

Combinatorial auctions with decreasing marginal utilities

In most of microeconomic theory, consumers are assumed to exhibit decreasing marginal utilities. This paper considers combinatorial auctions among such submodular buyers. The valuations of such buyers are placed within a hierarchy of valuations that exhibit no complementarities, a hierarchy that includes also OR and XOR combinations of singleton valuations, and valuations satisfying the gross substitutes property. Those last valuations are shown to form a zero-measure subset of the submodular valuations that have positive measure. While we show that the allocation problem among submodular valuations is NP-hard, we present an efficient greedy 2-approximation algorithm for this case and generalize it to the case of limited complementarities. No such approximation algorithm exists in a setting allowing for arbitrary complementarities. Some results about strategic aspects of combinatorial auctions among players with decreasing marginal utilities are also presented.     

An empirical assessment of cross‐cultural age self‐construal measurement: Evidence from three countries

This study investigated which age measures, independent or interdependent, were better for cross‐cultural consumer research. Specifically, it assessed the fit between the “actual” and “ideal” self‐concept model within the framework of self‐construal theory by examining the actual and ideal self‐attributed age identity across South Korea ( n = 480), China ( n = 207), and France ( n = 338) using both independent and interdependent age identity scales. Multivariate analyses revealed differences for individuated self‐schemata across the three countries for actual and ideal age self‐construal, as well as for actual other‐referent interdependent age self‐schemata. However, the reverse occurred too: The ideal interdependent ages showed a lack of difference across the three different cultures. Overall, the results indicate that interdependent decade scales are better than independent age scales for cross‐cultural consumer behavior studies. Though such scales are more complex, they are easy to translate and to administer, and simple to analyze and to interpret. Evidence also suggests that such scales are reliable and robust across disparate samples in the countries studied. © 2011 Wiley Periodicals, Inc.     

Trade integration and corporate income tax differentials

Building on recent contributions to the New Economic Geography literature, this paper analyses the relation between asymmetric market size, trade integration, and corporate income tax differentials across countries. First, relying on Ottaviano and Van Ypersele’s (J. Int. Econ. 67:25–46, 2005) foot-loose capital model of tax competition, we illustrate that trade integration reduces the importance of relative market size for differences in the extent of corporate taxation between countries. Then, using a dataset of 26 OECD countries over the period 1982–2004, we provide supportive evidence of these theoretical predictions, i.e., market size differences are strongly positively correlated with corporate income tax differences across countries, but crucially, trade integration weakens this link. These findings are obtained controlling for the potential endogeneity of trade integration and are robust to alternative specifications.     

Looking across borders: A test of spatial policy interdependence using local government efficiency ratings

Spatial patterns in (local) government taxation and spending decisions have received a lot of attention. Still, the focus on taxation or expenditure levels in previous studies may be incomplete. Indeed, (rational) individuals are likely to consider the level of spending on (or taxation for) public goods provision simultaneously with how much public goods they actually receive—thus assessing the ‘price/quantity’ of government policies. Therefore, the present paper argues that incumbents may want their ‘price/quantity’ ratio to be close to that in neighbouring regions. Analysing Flemish local governments' efficiency ratings for the year 2000 (which relate total spending to the quantity of locally provided public goods), we confirm the existence of neighbourhood effects in local government policies.     

Competing auctions with endogenous quantities

Two sellers decide on their discrete supply of a homogenous good. There is a finite number of buyers with unit demand and privately known valuations. In the first model, there is a centralized market place where a uniform auction takes place. In the second, there are two distinct auction sites, each with one seller, and buyers decide where to bid. Using the theory of potential games, we show that in the one-site auction model there is always an equilibrium in pure-strategies. In contrast, if the distribution of buyers values has an increasing failure rate, and if the marginal cost of production is relatively low, there is no pure-strategy equilibrium where both sellers make positive profits in the competing sites model. We also identify conditions under which an equilibrium with a unique active site exists. We deal with the finite and discrete models by using several results about order statistics developed by Richard Barlow and Frank Proschan [R. Barlow, F. Proschan, Mathematical Theory of Reliability, Wiley, New York, 1965; R. Barlow, F. Proschan, Inequalities for linear combinations of order statistics from restricted families, Ann. Math. Statist. 37 (1966) 1593-1601; R. Barlow, F. Proschan, Statistical Theory of Reliability and Life Testing, McArdle Press, Silver Spring, 1975].     

An intelligent tutoring system for the accounting cycle: Enhancing textbook homework with artificial intelligence

This paper describes an electronic tutoring system, developed using principles of artificial intelligence (AI), to help students learn the accounting cycle. Unlike other educational technologies, the tutoring system provides instruction and feedback that is tailored to each individual student and addresses not only problem-solving outcomes but also problem-solving processes. To assess the effectiveness of the tutoring system, we administered a pre-test and then required students in a sophomore accounting course to use either the tutoring system or their textbook as a reference when journalizing transactions for a homework assignment. We then administered a post-test. A pre-post analysis showed that the tutor group’s test performance increased approximately 27% points, whereas the textbook group’s test performance improved by only 8% points. Implications of these findings for instructors and researchers are discussed.
