After August 2007 the plumbing system that supplied banks with wholesale funding, the interbank market, failed because toxic assets obstructed the pipes. Banks were forced to squeeze liquidity in a “lemons market” or to ask for liquidity “on tap” from central banks. This paper disentangles the two components of the 3-month Euribor–Eonia swap spread, credit and liquidity risk and then evaluates the decomposition. The main finding is that credit risk increased before the key events of the crisis, while liquidity risk was mainly responsible for the subsequent increases in the Euribor spread and then reacted to the systemic responses of the central banks, especially in October 2008. Moreover, the level of the spread between May 2009 and February 2010 was influenced mainly by credit risk, suggesting that European banks were still in a “lemons market” and relied on liquidity “on tap” even before sovereign debt crisis unfolded in Europe.  相似文献

A model for the statistical analysis of the total amount of insurance paid out on a policy is developed and applied. The model simultaneously deals with the number of claims (zero or more) and the amount of each claim. The number of claims is from a Poisson-based discrete distribution. Individual claim sizes are from a continuous right skewed distribution. The resulting distribution of total claim size is a mixed discrete-continuous model, with positive probability of a zero claim. The means and dispersions of the claim frequency and claim size distribution are modeled in terms of risk factors. The model is applied to a car insurance data set.  相似文献

This article investigates the evolution of the gap between Italian regions and Italy as a whole during the period of 1980 to 2007. We tested for the presence of the stochastic and β-convergence hypotheses using different time series approaches. The former was studied, first, for the entire sample period and then, with an exogenous instantaneous break in the series. The presence of β-convergence, instead, was estimated considering a known and an unknown trend break date model. Our results show that most of the regions do not converge in an ‘actual’ way, since they do not present a stochastic and β-convergence simultaneously.  相似文献

This paper examines the role of coalition formation in the empirically observed negative correlation between employment protection and unemployment benefit. We study an economy composed of four groups of agents (capitalists, unemployed people, low- and high-skilled workers), each one represented by a politician. Politicians first form political parties and then compete in a winner-takes-all election by simultaneously proposing policy bundles composed of an employment protection level and an unemployment benefit. We first show that, in the absence of parties (i.e., in a citizen-candidate model), low-skilled workers are decisive and support a maximum employment protection level together with some unemployment benefit. We then obtain that, under some conditions, allowing for party formation results in all policy equilibria belonging to the Pareto set of the coalition formed by high-skilled workers together with unemployed people. Policies in this Pareto set exhibit a negative correlation between employment protection and unemployment benefit.  相似文献

In the information technology (IT) industry, which confronted a major transition phase during the 1990s, partnerships became a strategic component of the new ‘divided technical leadership’ that emerged from the industry's vertical disintegration. This paper attempts to evaluate the impact of 1676 partnerships on the financial performance (revenue and profit) of 14 large firms and 725 of their partners. On average, there is a positive impact of collaborative agreements on large incumbents and their partners' financial performance. These results vary according to the type, form and content of the agreement and according to the partner's field of activity. Incumbents get the most benefit from broad informal alliances while smaller and more hierarchical forms of partnerships (consortia, joint-ventures) do profit to their partners. For large incumbents, partnerships are more effective with partners from the services industry than with partners from the IT industry.  相似文献

Genetically modified rice with a high folate content, i.e., folate biofortified rice, was recently developed to tackle folate deficiency. A consumer segmentation study is conducted to explore its market potential in the Chinese Shanxi Province, where the burden of folate deficiency is among the world’s highest. Cluster analysis of 451 rice consumers identified three segments: enthusiasts (14.2%), cautious (41.2%), and opponents (44.6%). Enthusiasts obtain the highest score of GM food knowledge and attitudes and have the highest GM rice acceptance rate, followed by cautious and reluctant consumers. Regarding GM food information, enthusiasts use almost entirely audiovisual channels and rely more on the industry, while other segments depend more on informal channels and anti-GM sources. Trust levels in these channels/sources differ between enthusiasts (high), opponents (neutral), and cautious (low). Based on multinomial regression, a targeted communication approach is recommended with a focus on female, cautious consumers and rural, low-educated opponents.  相似文献

ABSTRACT

For media planners to combine multiple media across platforms to maximize synergy is a critical challenge within integrated marketing communication. For this study, in-depth interviews were conducted with experienced media specialists in leading agencies to explore how they integrate different out-of-home advertising media platforms in IMC strategies. The feedback of these experts was then used to propose a model of strategies to enhance synergy within out-of-home advertising campaigns. This model is a first of its kind for planning out-of-home advertising media across platforms and bridges a gap in the existing literature on media synergy and out-of-home advertising media strategy.  相似文献

Small firms have gained increasing attention in the innovation literature. Focusing mainly on manufacturing based literature we identified several key factors that contribute to the innovative potential of small firms. However, we do not know if these factors are recognised and used in small service firms. Distinguishing various types of service industries, our goal with this paper is threefold. First, we describe to what extent service firms use the key factors to their advantage. Second, we try to establish if there is a relation between the key factors and new product introductions. Third, we want to see if new product introductions indeed contribute to firm performance. After a survey among 502 Dutch service firms, we reveal some major differences between various types of service industries.  相似文献

The aim of this article was to analyse the value of human resources (HR) for competitive advantage and their influence on the firm's performance in the service industry. To achieve our goal, we have first proposed a resource-based framework to discuss the circumstances under which human resources can be a source of competitive advantage. Then, an empirical research was developed in the Spanish savings bank sector to analyse the relationship between HR management and the firm's performance. Our results, suggest that those savings banks which better combine their HR practices to create and to develop a strategic human capital pool have shown better levels of profitability and productivity.  相似文献

ABSTRACT

This article contributes to the existing literature on geographical indications by observing consumers’ stated preference for extra-virgin olive oil in two groups differing in their regional identity. In particular, consumers from two groups were asked to rank products in a contingent ranking survey. One group (“insiders,” Sicilian consumers) shared origin with a good product (Sicilian oil); the other group (“outsiders,” Rome and Milan) presented “no association” consumer-product. Results indicate that insiders are willing to pay more for goods originating from the region they identify with compared with a region associated with outsiders. Identity seems to give a bias by which a local product is not necessarily perceived as superior in absolute terms, but in relative terms: outside products are never considered better than inside options but are either inferior or equal in perceived value.  相似文献
