International portfolio diversification: Currency,industry and country effects revisited

We examine the relative importance of country, industry, world market and currency risk factors for international stock returns. Our approach focuses on testing the mean-variance efficiency of the various factor portfolios. An unconditional analysis does not show significant differences between country, industry and world portfolios, nor any role for currency risk factors. However, when we allow expected returns, volatilities and correlations to vary over time, we find that equity returns are mainly driven by global industry and currency risk factors. We propose a novel test to evaluate the relative benefits of alternative investment strategies and find that including currencies is critical to take full advantage of the diversification benefits afforded by international markets.     

Pricing Practices of Resellers in the Airline Industry: Posted Price vs. Name‐Your‐Own‐Price Models

I find that when a reseller with market power serves an airline company and only linear contracts are feasible, the airline prefers that the reseller utilizes the Name‐Your‐Own‐Price (NYOP) (a la Priceline) instead of the Posted Price (PP) (a la Hotwire) model. Essentially, the airline can better extract the surplus of the reseller if power over pricing is in the hands of numerous consumers, each bidding according to her preferences, instead of being concentrated in the hands of the reseller. Introducing two part tariff contracts or competition among resellers eliminates the distinction between the two pricing models. Either form of pricing generates the same outcome as vertical integration of the airline with the downstream market of resellers.     

Effects of Supplier and Customer Integration on Product Innovation and Performance: Empirical Evidence in Hong Kong Manufacturers

While the beneficial impacts of supplier and customer integration are generally acknowledged, very few empirical research studies have examined how an organization can achieve better product performance through product innovation enhanced by such integration. This paper thus examines the impact of key supplier and customer integration processes (i.e., information sharing and product codevelopment with supplier and customer, respectively) on product innovation as well as their impact on product performance. It contributes to existing literature by asking how such integration activities affect product innovation and performance in both direct and indirect ways. After surveying 251 manufacturers in Hong Kong, this study tested the relationships among information sharing, product codevelopment, product innovativeness, and performance with three control variables (i.e., company size, type of industry, and market certainty). Structural equation modeling with correlation and t‐tests was used to test the hypothesized research model. The findings indicate a direct, positive relationship between supplier and customer integration and product performance. In particular, this study verifies that sharing information with suppliers and product codevelopment with customers directly improves product performance. In addition, this study empirically examines the indirect effects of supplier and customer integration processes on product performance, mediated by innovation. This has seldom been attempted in previous research. The empirical findings show that product codevelopment with suppliers improves performance, mediated by innovation. However, the sampled firms cannot improve their product innovation by sharing information with their current customers and suppliers as well as codeveloping new products with the customers. If the adoption of supplier and customer integration is not cost free, the findings of this study may suggest firms work on particular supplier and customer integration processes (i.e., product codevelopment with suppliers) to improve their product innovation. The study also suggests that companies codevelop new products only with new customers and lead users instead of current ones for product innovation. For managers, this study has demonstrated that both information sharing and product codevelopment affect performance directly and indirectly. Managers should put more emphasis on these key processes, especially when linked with product innovation. Managers should consider involving their suppliers and customers in the early stages of design. Information sharing with suppliers is also important in product development. As suggested by this study, extensive effort on supplier and customer integration should be made to directly augment current product performance and product innovation at the same time.     

On Forward Induction and Evolutionary and Strategic Stability

We analyze which normal form solution concepts capture the notion of forward induction, as defined by E. van Damme (1989, J. Econ. Theory48, 476-496) in the class of generic two player normal form games preceded by an outside option. We find that none of the known strategic stability concepts (including Mertens stable sets and hyperstable sets) capture this form of forward induction. On the other hand, we show that the evolutionary concept of EES set (J. Swinkels, 1992, J. Econ. Theory57, 306-332) is always consistent with forward induction.

Optimal information revelation in procurement schemes

A buyer procuring a single input possesses private information about each potential supplier's degree of fit with the buyer's needs. She can search among suppliers either sequentially or simultaneously. As long as the distribution of the fit parameter is not overly skewed to the left, sharing information with suppliers yields intensified price competition under simultaneous search. Moreover, the buyer cannot benefit by providing suppliers additional information beyond their own fitness parameter. Information revelation is never optimal with sequential search.     

Customer Participation Behavior in High- Versus Low-Contact Services: The Multiple Roles of Customer Trust

ABSTRACT

In light of the changing roles of customers from service co-producer to value co-creator, the customer participation literature has conceptualized two types of participation behavior: co-production and value co-creation. However, there is a dearth of knowledge concerning both the antecedents of customer co-creation behavior and the outcomes of such behavior in relation to customer-perceived value and loyalty. Anchored in the trust-commitment theory, the present research (a) examines the effect of how a customer's trust in the service personnel could affect his/her cooperative behavior over the service design and delivery processes; and (b) investigates how the potential impact of a customer's trust in service personnel on his/her co-design and co-delivery behavior could be made contingent upon the customer's trust in the service brand and the types of high- versus low-customer-contact service contexts. Filling the aforementioned research gaps, the present research contributes to advance our knowledge of the roles played by trust at different levels of analysis in facilitating customer participation behavior and improving our appreciation of the customer contact service contexts when designing the service organization for maximizing service value and sustaining brand loyalty over time.     

Whistle-Blowing Systems and Legitimacy Theory: A Study of the Motivation to Implement Whistle-Blowing Systems in German Organizations

Until now, there has been no theoretical foundation that explains why organizations implement whistle-blowing systems. By understanding whistle-blowing systems as an instrument that is desired by society, the legitimacy theory could be transferred to the whistle-blowing concept. A survey of German managers shows that legitimacy theory may be supported. Further insights into legitimacy theory are given by the motivation for the design of the implemented systems. The survey shows that, in particular, the implementation of external whistle-blowing systems is seemingly not driven by desired effectiveness. This supports legitimacy theory, since it reveals that external systems are symbolic rather than substantive systems. However, the results do not hold for internal whistle-blowing systems because the implementation of internal systems is ostensibly driven by power theories. The results are interesting for the planned statutory whistleblower protection as they reveal a partially restrained attitude toward whistle-blowing. Whistle-blowing systems are not effective if management is not convinced of their benefits.     

Brand and performance signals in the choice of franchise opportunities

When choosing a franchise chain, potential franchisees must incorporate into their decision process the signals of franchise chain quality being sent to the market by the franchisor. Some of these signals along with potential franchisees' choices of franchise chain are analyzed. The results show that brand value and franchisee performance were the key signals used by Spanish franchisees during the period 2002 through 2008, when deciding to open a franchise outlet. The aim of this study was to contribute to strengthening the relationship between entrepreneurship and franchising in Spain from an empirical viewpoint.
