The contribution of genetics to milk composition: evidence from Spain

This article focuses on the role that genetic progress may play in improving milk quality. Despite important genetic advances in dairy production, the absence of genetic records in farm management databases has precluded empirical production models from explicitly accounting for differences in genetics across herds. The influence of genetics on milk composition is analyzed by splitting milk production into protein, fat, and other components. The article explores some modeling issues associated with the specification of the effect of genetics in this multi‐output technology framework. In particular, genetic indexes are considered as allocable inputs and the remaining inputs as nonallocable. Our results show that genetics have a significant impact on milk composition. In particular, we find that farmers’ income increases by 6.6% when genetic indexes are augmented by one sample standard deviation.     

The Effects of Additive Outliers and Measurement Errors when Testing for Structural Breaks in Variance*

This article discusses the asymptotic and finite‐sample properties of the CUSUM tests for detecting structural breaks in volatility when the data are perturbed with (additive) outliers and/or measurement errors. The special focus is on the parametric and non‐parametric tests in Inclán and Tiao (1994) and Kokoszka and Leipus (2000) . Whereas the asymptotic distribution of the former can be largely affected, the distribution of the latter remains invariant and renders consistent break‐point estimates. In small samples, however, large additive outliers are able to generate sizeable distortions in both tests, which explains some of the contradictory findings in previous literature.     

Implications of perceived competitive advantages,adaptation of marketing tactics and export commitment on export performance

The aim of this exploratory paper is to fill an important gap in the international marketing literature by examining the influence of firm behavior in foreign markets (export commitment and adaptation of marketing tactics) on perceived competitive advantages and export performance. Using a sample of 150 Spanish export firms, the study found that firms that are more committed to their foreign markets are more willing to adapt elements of the marketing program. These firms also perform better in foreign markets. Moreover, the results also point out that adapting marketing tactics does not have direct effects on export performance, although it does have on the achievement of perceived competitive advantages in foreign markets, which positively influence export performance.     

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.     

The role of retentions in how marketing managers change their strategic orientation

This study looks at how a marketing organization changed its strategic orientation in response to environmental factors, and at the influence of retentions on the change effort. Retentions are defined , here as the concepts and mental models used by marketing managers when trying to respond to environmental changes. The influence of retentions on strategic orientation and factors affecting how retentions change are studied in the context of how a bank trust department responded to the deregulation of the financial services industry between 1982 and 1984. The dominant retentions held by managers both before and after deregulation are presented, and the events that contributed to the change of the retentions are examined. The results suggest that retentions prior to deregulation focused on external sources of influence and were associated with a defender strategic orientation. Retentions after deregulation, once the organization's strategic orientation stabilized, focused on critical resources and competitors and were associated with an analyser orientation. The adoption of the new retentions lagged deregulation by several years, and the transition did not match the steps prescribed by the marketing and strategic management literature. Instead, the transition took place through an iterative sequence of behaviours and evaluations more characteristic of the organizing model (Weick 1979). Managers changed their retentions incrementally by enacting small changes, evaluating the outcomes of their behaviour, and letting the outcomes redefine their retentions.     

Organizing for continuous technology acquisition: the role of R&D geographic dispersion

External technology acquisition has been proved to be an important strategy to enhance firms’ innovation performance. However, previous studies claim that companies acquiring technologies tend to not carry on with this strategy over time, thus limiting their attitude toward continuous technology acquisition. Moreover, the extant literature also highlights that this attitude is strongly influenced by their organizational structure. Therefore, in the present paper, we investigate the relationship between how firms organize R&D activities and continuous technology acquisition. Specifically, given the increasing globalization of technological development, we focus on the role of R&D geographic dispersion, and how its influence is moderated by firms’ technological diversification. We tested our hypotheses on longitudinal data of 303 biotechnology firms that acquired, at least, one USPTO patented technology over the period 1982–2012. Results reveal that R&D geographic dispersion is curvilinearly (inverted U-shaped) related to continuous technology acquisition, with negative returns occurring earlier in technology-diversified companies.
