Abstract

In an extension of generational theory, the present research argues that ethical ideology (i.e. idealism vs. relativism) impacts attitude toward the ad (Aad), attitude toward the brand (Abrand), and purchase intention (PI). Additionally, this research examines how this relationship is mediated by the ethical appraisal of the ad and moderated by the level of ethnic identification (i.e. high vs. low). The results of this experiment provide additional evidence in support of generational theory which states that each generational cohort holds distinct ethical ideologies. Furthermore, this study identifies differences in the participants’ responses to alcohol ads resulting from their personal values (i.e. in this study we focus on strength of ethnic identification).  相似文献

Learning capacity is a critical factor for a firm’s innovation and competitiveness. This study explores the issue of how knowledge in inter-firm relationships with distributors influences manufacturers’ exploitation- and exploration-based innovations and performance. The empirical model examines the effect of three different types of knowledge-related issues in inter-firm relationships: (i) the acquisition of substantial knowledge (about products, technology, or markets) from distributors; (ii) the learning about collaborating with each distributor as the relationship evolves; and (iii) the general firm’s knowledge about managing distributors. A model of learning—innovation—performance is developed and tested in a sample of 201 firms in the food and beverages sector. The results reveal that: (i) knowledge about managing distributors promotes continuous learning from them; (ii) learning to collaborate is critical, as it favours knowledge acquisition and both types of innovations (exploitation- and exploration-based); (iii) learning from distributors weakens firms’ tendency to stress one type of innovation strategy over another; and (iv) knowledge in inter-firm relationships with distributors affects performance in a completely mediated way, that is, through innovation. Theoretical and managerial implications of these findings are discussed in the conclusion of the paper.  相似文献

Abstract:

The financial and business expansion towards both sides of the Mexico-U.S. border, what could be called the financial diaspora that accompanies Mexican´s migration to the United States and U.S. Corporations to Mexico, has been a process full of nuances and components with different characteristics. Beyond the governments and their migratory and investment policies, the characteristics of the different migrant groups and corporations, the cultural gaps, and the “progressive” institutional changes are subject to a dynamic of survival-assimilation-earnings. Even when powerful trials of organization are observed, a strong and imminent current of regressive institutional change (Veblen) has been gaining space. This article is circumscribed to analyze some key aspects of the financial behavior Mexican migrants to the United States, who have become entrepreneurs, have had. Their enormous limitations of financing are exposed, including the different stages to access credit to the businesses of residents in Mexico and to Mexican businesspeople abroad. The article contends the transformation in financing on both sides of the border has been decisive.  相似文献

Lorenzo Sacconi's The Social Contract of the Firm (Berlin, Springer, 2000) is a major contribution to the normative theory of the firm. It contains a full-fledged contractarian explanation of the role of Corporate Codes of Ethics. Sacconi proposes a game-theoretical model of the normative structure of the firm, including explicit and implicit contracts binding the members of the organisation, and the so-called constitutional contract: the hypothetical agreement that sets the basic co-operative structure in which the organisation consists. While Sacconi's theory is sound and full of suggestions, it is doubtful whether it completely grasps the nature of organisational ethics. In presenting organisations as the product of an agreement among self-interested individuals, the model does not account for the social and systemic embeddedness of business institutions. This paper points to several shortcomings of Sacconi's view, and explores alternative understandings of a contractarian morality as applied to business ethics.  相似文献

Many studies reveal that male-female wage differentials increase with the level of unemployment, suggesting that women are hurt by a recession more than men. However, the 1990–94 economic recession in Spain contributed to reduce the gender wage gap by almost 5 percentage points (from 83.94 percent in 1990 to 90.44 percent in 1994). This was mainly due to the relative increase in services industry employment, the activity where the gender wage gap is the lowest.  相似文献

Water supply instability is one of the main risks faced by irrigation districts and farmers. Water procurement decision optimisation is essential in order to increase supply reliability and reduce costs. Water markets, such as spot purchases or water supply option contracts, can make this decision process more flexible. We analyse the potential interest in an option contract for an irrigation district that has access to several water sources. We apply a stochastic recursive mathematical programming model to simulate the water procurement decisions of an irrigation district's board operating in a context of water supply uncertainty in south‐eastern Spain. We analyse what role different option contracts could play in securing its water supply. Results suggest that the irrigation district would be willing to accept the proposed option contract in most cases subject to realistic values of the option contract financial terms. Of nine different water sources, desalination and the option contract are the main substitutes, where the use of either depends on the contract parameters. The contract premium and optioned volume are the variables that have a greater impact on the irrigation district's decisions.  相似文献

Regional trade in South America since independence has long been much smaller than would be expected if geography were the only constraint on trade. Several potential explanations exist, including low technological and demand complementarities; low productivity; and high natural and policy barriers to trade. Focusing on the latter explanations, policy makers have long advocated a South American/Southern Cone Free Trade Area—proposed as early as 1889. Would reductions in trade costs have been sufficient to raise trade significantly, or was trade low for other reasons? We study bilateral trade between 1910 and 1950, when large external shocks altered global supply and demand. These shocks help us show that intra‐regional trade could have been boosted by reductions in trade costs. Trade among Argentina, Bolivia, Brazil, Chile, and Peru could have benefited from more benign trade policies or better infrastructure. Regional trade in textiles, which took off from the 1930s, supports our argument that trade improved when trade costs fell.  相似文献

The state forecasting model (SFM) developed herein predicts the probability that a recession will begin or end within the next quarter. It is also important to forecast the state, as models prone to false alarms are not useful. The model combines parsimony, predictive accuracy, and ease of estimation using readily available data. No regressor is benchmark‐revised, and only one is seasonally adjusted. The SFM correctly forecasts, out‐of‐sample, the binary state in 163 of 164 quarters for an overall proportion of correct forecasts of 0.994. The results demonstrate the discriminating ability, longevity and striking forecasting ability of the model. A benchmark model based on the newly revised Leading Economic Index of the Conference Board has zero marginal predictive power in the presence the SFM.  相似文献

Abstract

Multinational Enterprises (MNEs) can choose between exporting, introducing foreign direct investment (FDI), and licensing to a domestic firm among other modes of entry to a new market. Yet, this decision may be affected by the strength of intellectual property rights (IPR). Thus, this paper analyzes the effect of stronger IPR on the entry modes chosen by MNEs. We propose a theoretical model that predicts that in the presence of stronger IPR, MNEs would choose licensing instead of FDI as an entry mode. We test the predictions of the model using plant-level data for Chile for the period 2001–2007. We exploit the exogenous reform of IPR in 2005, controlling for the activities of industries where high levels of technology transfer and imitation are important factors. The main results show that stronger IPR change the mode of entry chosen by MNEs. In this case, FDI is replaced by licensing. This is explained by Chile’s high absorptive capacity during this period. We test whether this effect differs across high- and low-tech industries and conclude that the displacement of FDI is less severe in high-tech industries.  相似文献
