The advertising and marketing literature have established that celebrity endorsements constitute an effective way to enhance attitudes toward brands and increase purchase intents. However, there are no relevant studies on digital influencers. This study addresses the research gap by examining the effect of digital influencers' attractiveness and the effect of the congruence between a digital influencer and a brand on consumer attitudes and purchase intentions. By applying structural equation modeling to a sample of 307 followers of digital influencers, a model was tested and group analysis was performed for two categories (“entertainment & video games” and “fashion & beauty”). The results show that both brand attitudes and purchase intentions are influenced by the digital influencer's attractiveness (which includes both likeability and familiarity) and by the congruence between the digital influencer and the brand. This study makes several contributions to both theory and practice, which are highlighted in this paper.  相似文献

We study the role of institutional investors around the world using a comprehensive data set of equity holdings from 27 countries. We find that all institutional investors have a strong preference for the stock of large firms and firms with good governance, while foreign institutions tend to overweight firms that are cross-listed in the U.S. and members of the Morgan Stanley Capital International World Index. Firms with higher ownership by foreign and independent institutions have higher firm valuations, better operating performance, and lower capital expenditures. Our results indicate that foreign and independent institutions, with potentially fewer business ties to firms, are involved in monitoring corporations worldwide.  相似文献

The structure and financing of science and technology activities are undergoing a slow, but profound, change. This change can be briefly characterized as a shift from relying and supporting public science to a stronger emphasis on “market-based” incentives for science and technology. In this paper we analyze this shift in a historical perspective, discussing both the theoretical explanations and the empirical trends of the ongoing change. While we do not claim to provide a comprehensive and exhaustive identification of the causes of this shift, we argue that it is largely driven by the perception of a shift of the U.S. policy towards market-based, rather than publicly supported, incentives for science and technology. This, in turn—given the strong economic performance of the United States over the 1990s—has influenced policies in most OECD countries, especially in Europe.We conclude by analyzing the evolution of research in U.S. higher education and find two major trends: an increasing diversity in the number of institutions of different types other than universities and a steady and continuous public funding of the leading U.S. universities. This has allowed the construction of an infrastructure now used largely by the private sector, but it also noted that the United States has not compromised public support for core areas or in those fields in which there is a clear perception that market incentives are not sufficient for meeting the strategic targets of the U.S. policy. The implication is that there is a considerable policy diversity in the U.S. practice and that all aspects of this diversity should be considered when using the United States as a reference.  相似文献

Jeff Crump's discussion of housing policy in the United States is highly polemic but not very analytic or informative. Crump argues that federal housing policy is attempting to move people out of public housing and into the private housing market and the lowwage labor force. However, he fails to support his argument with credible evidence. My comments point out the most egregious of Crump's claims. I start with Crump's most extreme contentions that housing policy is coercing public housing residents into the low‐wage labor force. I then question his dismissive attitude toward the problems confronted by residents of distressed public housing and policies designed to help low‐income families move out of impoverished neighborhoods. I subsequently show how Crump exaggerates the extent to which federal housing policy is clearing central cities of subsidized low‐income housing. I conclude with a few words on the serious issues that a more informed critique of US housing policy could have raised. L'exposé de Jeff Crump sur la politique du logement aux Etats‐Unis relève principalement de la polémique, plus que de l'analyse ou de l'information. Selon lui, la politique fédérale tente de déplacer la population des logements sociaux vers les marchés de l'habitat privé et de la main‐d'?uvre à bas salaires. Toutefois, il n'apporte aucune preuve crédible à son propos. Ma réaction porte sur ses arguments les plus insignes, en commençant par ses allégations extrémistes selon lesquelles la politique du logement contraint les habitants des logements publics à des emplois peu rémunérés. Je remets ensuite en cause son dédain à l'égard des difficultés que rencontrent les résidents des logements sociaux insalubres, sans oublier les politiques prévues pour aider les familles à faibles revenus à quitter les quartiers pauvres. En conséquence, à mon avis, Crump exagère la mesure dans laquelle la politique fédérale élimine des centres‐villes les habitats à loyer modéré subventionnés. En quelques mots, ma conclusion porte sur les questions graves qu'aurait pu soulever un commentateur mieux documenté sur la politique du logement aux Etats‐Unis.  相似文献

This study compares the patterns of entry, survival and growth of domestic and foreign owned firms. We show that the post-entry behavior of foreign owned firms is quite different from that of their domestic counterparts. Among foreign entrants, we were able to distinguish between those which proceed by creating a new firm and those that acquire an already existing business. Our evidence reveals that the choice of the mode of entry in foreign markets exerts an impact upon the performance of firms that persists long after the moment of entry. As a consequence, our work clearly indicates that there is much to be gained in the understanding ofthe process of entry in foreign markets by studying the behavior of entrants over their first years in these markets.  相似文献

This paper studies the dispersion around the expected compensation of workers before and after controlling for hierarchical positions in cross-section data samples. From data for Spanish managers, we find that this dispersion decreases with education and work experience before entering the current job and increases with job tenure. This finding contrasts with previous research that finds a positive association between compensation dispersion and education and work experience. We explain the new finding through a model of learning that separates compensation dispersion between jobs and within jobs (hierarchical positions). The model takes advantage of the information revealed when workers are promoted to their current hierarchical positions and allows for more robust tests of learning theories.  相似文献

This paper draws attention for the fact that traditional Data Envelopment Analysis (DEA) models do not provide the closest possible targets (or peers) to inefficient units, and presents a procedure to obtain such targets.It focuses on non-oriented efficiency measures (which assume that production units are able to control, and thus change, inputs and outputs simultaneously) both measured in relation to a Free Disposal Hull (FDH) technology and in relation to a convex technology. The approaches developed for finding close targets are applied to a sample of Portuguese bank branches.  相似文献

The European Commission issued a proposal for reform of some aspects of Communitary competition policy. In particular, proposes a shift from ex-ante control (notification system) to an ex-post control regime of agreements (or decisions) conflicting with Article 81 (Ex-Article 85).We highlight the expected effects of this shift on the type of agreements that firms will implement. The type of agreements has been taken as exogenous in most analysis of the reform proposal. We contend that significant economic effects may result from recognizing the endogeneity of agreements.We predict that the proposed reform will result, in general, in firms implementing less restrictive agreements.  相似文献

The recent applied production theory literature focusing on the economic performance of firms has increasingly recognized the importance of scale effects on costs and therefore efficiency. These scale effects may include short run returns due to fixity of privately demanded inputs (i.e., capital, long run internal returns to scale, and external factors affecting costs. Since these different types of scale effects can be thought of as shifts in and movements along cost curves, the different cost effects of such factors can be identified in a framework which explicitly takes them into account in the definition ofscale.In this article we formalize such a framework, and then use it to measure short run, long run (internal) and external scale effects from fixity of private capital, nonconstant returns to scale and public infrastructure. We then use these measures to identify the impacts of these different scale factors on productivity growth. The focus on public infrastructure as an important external scale factor is motivated by the current theoretical and policy interest in this issue; we show how a structural production theory model provides a rich basis for the analysis of the cost effects of infrastructure investment.  相似文献
