We address the role of information heterogeneity in the Euro interbank market for unsecured term lending. We use high-frequency quotes of bid and ask prices to estimate probabilities of informed trading for contract maturities from one month to one year. The dataset spans from November 2000 to March 2008, and includes the relevant events that characterize the developments of the euro area money market. We find that the probability of finding a trading counterparty with a wider information set has risen since the eruption of the turmoil. Our results also show that the probability of trading with a better-informed bank is higher on days when open market operations take place, and at the end of the maintenance period. This effect has strengthened during the turmoil. This suggests that the loose supply of money of the ECB has not dampened the distortions arising from asymmetric information in the unsecured money market.  相似文献

We show that uncertainty about parameters of the short rate model can account for the rejections of the expectations hypothesis for the term structure of interest rates. We assume that agents employ Bayes rule to learn parameter values in the context of a model that is subject to stochastic structural breaks. We show that parameter uncertainty also implies that the verdict on the expectations hypothesis varies systematically with the term of the long bond and the particular test employed, in the same way that is found in empirical tests.  相似文献

This paper combines qualitative information from the Eurosystem Bank Lending Survey with micro-data on loans for the participating Italian banks to assess the role of supply and demand factors in lending to enterprises developments, with a focus on the 2007-2009 financial crisis. Both demand and supply have played a relevant role, in the whole sample period and during the crisis. A counterfactual exercise shows that the effect of supply factors on the growth of lending was strongest after the Lehman collapse. On average, over the crisis period the negative effect on the annualized quarter-on-quarter growth rate of the panel banks’ lending to enterprises can be estimated in a range of 2.3-3.1 percentage points, depending on the specification. About one fourth of the total supply effect can be attributed to costs related to the banks’ balance sheet position, the rest to their perception of credit risk.  相似文献

One of the necessary features of markets to produce efficient pricing is competition between information-based investors who quickly impound new information into price. However, a significant proportion of funds invested in today’s equity markets are in the hands of managers who pursue a style that utilises little or none of the available information. We simulate such a market where the funds are being managed using the following three investment styles: fundamental, momentum and index. We confirm that the major pricing anomalies that have been highlighted previously in the literature are a natural consequence of competition between managers utilising these three investment styles. More importantly, we show that this situation is unlikely to change as long as markets continue to be dominated by costly active managers with clients who pursue outperformance.  相似文献

The aim of this study was to evaluate the combined influence of several lifestyle, health and housing factors in the occurrence of home injuries (HIs) among the elderly. The subjects were recruited from 10 hospitals in Rome, Italy. This study is a paired case-control study. Cases included subjects, aged 65-85 years, who visited the Emergency Department for an HI and were subsequently hospitalised (15 September 2004-30 June 2005). Controls were the subjects of the same gender, age (±3 years) and area of residence of cases. A conditional logistic regression model was used for analysing the variables obtained. In this study, we enrolled 107 hospitalised cases. It was found that the living room was the place where 33% of the accidents occurred. Eighty-seven per cent of the accidents were falls, and 33% of the accidents were the immediate consequence of sudden malaise. One-half of the cases reported one or more leg fractures. The variables that were independently associated with HI were poor household illumination, poor emotional status, regular physical activities and housekeeping activities. We conclude that this study shows the areas of intervention to target HI prevention activities.  相似文献

This paper develops a theory of the centralization of firms engaged in multi-market collusive agreements. A centralized organization (called the unitary or U-form) allows price coordination across several markets, whereas with decentralized (the multidivisional or M-form) firms the probability that the antitrust authority will find evidence of collusion on one market while investigating the other is lower. We show that the firm’s choice of internal structure depends to a large extent on product substitutability and the instruments used by the antitrust authority.  相似文献

Innovation is a collective process that entails the coordination of distributed knowledge across diverse organizations. Technology infrastructures provide innovation systems with governance mechanisms to create and sustain complementarities across otherwise dispersed competences. The paper presents innovation platforms as a specific case of technology infrastructure. Operating strategically at the interface between the public and the private sectors, platforms enable capacity- and capability-building for individuals, teams and organizations. Illustrative evidence on innovation platforms in the United Kingdom and Italy confirms the importance of institutional responsiveness to stimulate variety and ensure coordination in the context of collective innovation processes.  相似文献

In his Theory of Economic Development, Schumpeter introduced the distinction between different innovation types. Since then, a variety of studies have addressed this topic. However, despite of the recognised significance of more de-verticalised organisational forms in shaping and directing firms' innovative performance, no attempt has been made, as far as our knowledge is concerned, to investigate whether these practices are linked to the introduction of specific innovation types. The aim of the study is to fill this gap by investigating the impact of de-verticalised forms of labour organisational practices, different modes of organising research and development activity and the nature of employees' competences on the likelihood of introducing different types of innovations, controlling for firm's size and sectoral specificities. The results obtained on a sample of 199 firms located in Reggio Emilia province in Italy confirm that innovation development is a heterogeneous activity. The empirical evidence gathered also shows that foreign and domestic firms do not differ, to some extent, in the introduction of different kinds of innovations. However, being foreign or domestic is a discriminating factor in the introduction of innovations stimulating labour organisational developments.  相似文献
