A Semiparametric Analysis of the Term Structure of the US Interest Rates*

The short end of the US$ term structure of interest rates is analysed allowing for the possibility of fractional integration and cointegration. This approach permits mean‐reverting dynamics for the data and the existence of a common long run stochastic trend to be maintained simultaneously. We estimate the model for the period 1963–2006 and find it compatible with this structure. The restriction that the data are I(1) and the errors are I(0) is rejected, mainly because the latter still display long memory. This result is consistent with a model of monetary policy in which the Central Bank operates affecting contracts with short term maturity, and the impulses are transmitted to contracts with longer maturities and then to the final goals. However, the transmission of the impulses along the term structure cannot be modelled using the Expectations Hypothesis.     

A Fuzzy Clustering Algorithm Based on the Analogy with Mechanical Physics: MeccFuz

This paper presents a new algorithm of fuzzy clustering, based on analogy withmechanics physics. The vectors x_i are compared with `material points' and the clusters can be looked on as material points clouds, that are characterized byspecific units. The choice is based on a study of potential energy. Once a specificunit is chosen, we calculated the membership of the other units whit respect it.A study of a sociology test is performed and the results are very encouraging,though an further deepening is needed like a thermodynamics analogy application.     

ISA 570: Italian Auditors’ and Academics’ Perceptions of the Going Concern Opinion

This study aims to identify which of the indicators used to assess whether an entity may not be able to continue as a going concern are regarded by Italian partners in auditing firms and Italian accounting and finance academics as being the most important. The indicators and ratios are those pursuant to auditing standard ISA 570 Going Concern, the literature and professional practice. ISA 570 does not suggest a hierarchy of these indicators, because they are only examples of events or conditions that, individually or collectively, may cast significant doubt on the entity's ability to continue as a going concern (GC), nor does it suggest specific ratios. To this end, an online survey was administered to partners in auditing firms and to the university faculty of Accounting and Finance. The paper contributes to enriching previous literature by providing insights into how Italian auditors and Italian financial reporting scholars prioritise GC indicators suggested by ISA 570. The results have the potential to help auditors and directors focus on the most relevant indicators in a GC assessment.     

The dynamic interrelation between external finance and bank credit

This article studies the interrelation among the volumes of bonds and stocks issued by non-financial firms, and levels of industrial loans outstanding in the United States. These aggregates are co-integrated and characterized by asymmetric volatility. Their co-movements are driven by financial indicators such as the yield spread, size of loan market and market volatility. Bond and stock issuance are positively correlated, and even more so during the expansionary phase of the cycle. Loans outstanding and bond issuance are negatively correlated, and their substitutability increases in periods of economic downturn, highlighting the importance of bond markets to mitigate credit crunches.     

The erosion of personal norms and cognitive dissonance

In this article, we study how personal norms and behaviour interact and evolve when agents try to reduce cognitive dissonance, and how this dynamic relates to Nash equilibrium. We find that in long run, agents play, and norms prescribe, Nash equilibrium in material payoffs (in the absence of norms). Our model captures two main facts: (i) norms erode along the play of the game; (ii) the erosion of norms depends on the set of possible economic choices, so that the policy maker can potentially influence them.     

What is the CSR’s Focus in Healthcare?

The concept of corporate social responsibility (CSR) has been the subject of several academic contributions, but in the health sector the development of an interest in this subject is very recent. Although many practices in healthcare are already socially responsible, progressing from a series of socially responsible behaviours to a socially responsible organization entails a more consolidated awareness of the health sector’s mission and the needs of its participants. In this paper, we will review the different studies published that address the relationship between the healthcare sector’s corporate responsibility and society, with the aims of individuating the prevailing foci that are emerging and categorizing the proposed contributions according to these foci: social responsibility and organization; social responsibility and social impact; social responsibility and competitiveness. Finally, the paper finishes with a personal definition of CSR and its correlated ethical roots.     

Does the digital divide matter? The role of information and communication technology in cross-country level and growth estimates

The bulk of information and communication technology is made of weightless, implementable, and infinitely reproducible knowledge products (such as software and databases). These products are transferred by telephone lines, accessed through internet hosts, and processed through personal computers. In this work, the coefficient of the labour augmenting factor in the aggregate production function has been estimated using proxies of variables crucially affecting the diffusion of (non-rival and almost non-excludable) knowledge products. This specification provides interesting answers to some of the open issues in the existing growth literature. The most recent information, though available for a limited period, shows that telephone lines, personal computers, mobile phones, and internet hosts significantly affect levels and growth of income per worker across countries. The result is robust to changes in sample composition, econometric specification, and estimation approach.     

Capturing the real value of patent analysis for R&D strategies

Patent information can be used for strategic planning purposes. Conventional patent analysis has commonly focused on factual information and, in particular, on information extraction, visualisation and interpretation. Less scholarly attention has been devoted to the strategic role of an integrated system of patent intelligence in supporting decision-making in R&D investments. Our paper addresses this gap and explores how patent analysis may benefit those firms that intend capturing the beneficial effects of Open Innovation. We also critically discuss the intrinsic limits of both patent information and patent analysis, which should be taken into account by systems of patent intelligence.
