ABSTRACT

The authors studied how knowledge derived from firms’ relationships—the so-called second-hand knowledge—is likely to influence their internationalization process. In this article, they examine how a European producer of textiles is able to sell worldwide, including to China, a highly competitive player in this industry. This article discusses models of firms’ networks and the extent to which such networks generate important knowledge that can explain internationalization behavior—how it is able to influence the selection of foreign markets and the entry mode used. The authors use the revised version of the Uppsala model of internationalization, which emphasizes the roles of trust-building, knowledge, and creation of opportunities within relationships.  相似文献

When should marketers emphasize attributes or benefits in their communications? Grounded in construal-level theory, the results of four studies suggest that when a purchase is planned for the distant future or when construal levels are high, benefit-based appeals are more persuasive than attribute-based appeals. By contrast, when a purchase is planned for the near future or when consumers are predisposed to low construal levels, attribute-based appeals are equally as persuasive as benefit-based appeals. However, when low construal levels are temporarily induced using a mind-set manipulation, attribute-based appeals are found to be more persuasive than benefit-based appeals. Moreover, we demonstrate how these effects occur only when processing fluency is uninhibited. This research establishes an important link between these appeal types and construal levels, subsequently demonstrating when marketers should use these appeals.  相似文献

The Brazilian Amazon deforestation is the context for this article, approached as a crime against humanity and wildlife. Recently, Amazon forest fires have also worried most of the economically developed nations, generating criticism and demanding that the Brazilian Government be more active in preventing fires and deforestation. It is necessary to guarantee the wellbeing and health of millions of animal species that live in this habitat, avoiding their extinctions and encouraging the preservation of the forest and its inhabitants. Agribusiness, together with illegal timber trade, are blamed for most of the deforestation. In this paper, we present and discuss Brazilian Amazon deforestation data, addressing the role of agribusiness as dependent on good environmental governance. We argue how stewardship behavior needs to become a path to stop deforestation and wildlife eviction and we reflect on what marketers in Brazil and the world can do to better protect the Amazon rainforest. We conclude that the Government, companies, and society must be coresponsible for the protection of the Amazon rainforest through conservation transparency, dialogue, environmental awareness, and sustainability in production and consumption practices.  相似文献

Questo lavoro discute un modello di mercato finanziario basato sulla teoria della vitalità associata allo studio delle inclusioni differenziali. Il modello permette di esplicitare l'esistenza di una relazione di dipendenza tra le quantità di un titolo detenute dagli agenti ed il suo prezzo di mercato. Basandosi su questa, è possibile ottenere rigorosamente l'esistenza di un sentiero temporale per il prezzo senza bisogno di introdurre ipotesiad hoc.
Summary This work discusses a model of a financial market based on viability theory and differential inclusions. The model makes it explicit the existence of a relationship between the quantities of a security held by agents and its market price. Based on this, we show how to establish rigorously the existence of a time path for the price which in the literature is usually assumed without much justification.


Ringraziamo E. Castagnoli per alcuni utili commenti. Le conversazioni con J.-P. Aubin, F. Moriconi e F. Ortu sull'etimologia e l'interpretazione dei concetti di vitalità ci sono state di grande beneficio.  相似文献

We formulate and solve a risk parity optimization problem under a Markov regime-switching framework to improve parameter estimation and to systematically mitigate the sensitivity of optimal portfolios to estimation error. A regime-switching factor model of returns is introduced to account for the abrupt changes in the behaviour of economic time series associated with financial cycles. This model incorporates market dynamics in an effort to improve parameter estimation. We proceed to use this model for risk parity optimization and also consider the construction of a robust version of the risk parity optimization by introducing uncertainty structures to the estimated market parameters. We test our model by constructing a regime-switching risk parity portfolio based on the Fama–French three-factor model. The out-of-sample computational results show that a regime-switching risk parity portfolio can consistently outperform its nominal counterpart, maintaining a similar ex post level of risk while delivering higher-than-nominal returns over a long-term investment horizon. Moreover, we present a dynamic portfolio rebalancing policy that further magnifies the benefits of a regime-switching portfolio.  相似文献

Abstract: This paper explores the main determinants of the use of the cost accounting system (CAS) in Portuguese local government (PLG). Regression analysis is used to study the fit of a model of accounting changes in PLG, focused on cost accounting systems oriented to activities and outputs. Based on survey data gathered from PLG, we have found that the use of information in decision‐making and external reporting is still a mirage. We obtain evidence about the influence of the internal organizational context (especially the lack of support and difficulties in the CAS implementation) in the use for internal purposes, while the institutional environment (like external pressures to implement the CAS) appears to be more deterministic of the external use. Results strengthen the function of external reporting to legitimate the organization's activities to external stakeholders. On the other hand, some control variables (like political competition, usefulness and experience) also evidence some explanatory power in the model. Some mixed results were found that appeal to further research in the future. Our empirical results contribute to understand the importance of interconnecting the contingency and institutional approaches to gain a clear picture of cost accounting changes in the public sector.  相似文献

This article examines the reputation recovery of Portugal's public debt during the war of liberation against the former Habsburg ruler. Using novel datasets on long- and short-term debt and nominal interest rates, this study provides evidence that the sovereign borrower used debt credibility to build a pact of regime in a revolutionary context with implications for financing the war. The Portuguese kings followed an implicit budget balance rule as a reputational scheme, which made Portugal an exceptional case of military success with a low debt-to-GDP ratio and low interest rates. These conclusions contribute to the literature in various attributes of war finance, debt management, and state-making by showing that default avoidance could be as important to military success as fiscal capacity.  相似文献

Maturity models (MM) have been used by different enterprise segments. However, while many MM have been developed, few have been validated because of the lack of studies that demonstrate how to classify model levels. This study investigates the literature that presents assessment models for classifying maturity levels as well as the development of the research area. A systematic literature review was carried out, finding 409 relevant papers and a list of the few methods for classifying the maturity level. This review enabled us to update the state of the art on MM and identify gaps that may prompt future research.  相似文献
