The Relative Valuation of Caps and Swaptions: Theory and Empirical Evidence

Although traded as distinct products, caps and swaptions are linked by no-arbitrage relations through the correlation structure of interest rates. Using a string market model, we solve for the correlation matrix implied by swaptions and examine the relative valuation of caps and swaptions. We find that swaption prices are generated by four factors and that implied correlations are lower than historical correlations. Long-dated swaptions appear mispriced and there were major pricing distortions during the 1998 hedge-fund crisis. Cap prices periodically deviate significantly from the no-arbitrage values implied by the swaptions market.     

Throwing Good Money After Bad? Cash Infusions and Distressed Real Estate

When a leveraged real estate project experience cash-flow problems, the owner must either inject additional cash or default on the mortgage. We show that it is not optimal for the owner to default as soon as net cash flow becomes negative. Surprisingly, the owner can expropriate some of the mortgage lender's wealth by injecting cash and continuing to pay interest. When the owner has cash constraints, outside investors may be able to extract significant economic rents by financing distressed real estate projects. These results have interesting implications for mortgage lending and the pattern of real estate transaction volume.     

Effects of traits,self-motivation and managerial skills on nursing intrapreneurship

Following the introduction of quasi-markets into publicly funded healthcare systems, nurse intrapreneurs who create innovations within these systems have become increasingly important to improving healthcare outputs. This study sought to examine how self-motivation and managerial skills mediate the influence of entrepreneurial traits on nurses’ intrapreneurial intentions in the Portuguese National Health Service. A structural equation model was assessed using primary data collected from a sample of 536 nurses working at seven public hospitals in Portugal. The results suggest that nurses who are more determined to become intrapreneurs are more likely to take risks, more self-confident about their managerial skills and slightly more self-motivated. In addition, while innovativeness has no significant effect, proactivity contributes to increasing nurses’ self-confidence in their own skills.

     

A network approach for assembling and linking input–output models

Input–output (IO) models, describing trade between different sectors and regions, are widely used to study the environmental repercussions of human activities. A frequent challenge in assembling an IO model or linking several such models is the absence of flow data with the same level of detail for all components. Such problems can be addressed using proportional allocation, which is a form of algebraic transformations. In this paper, we propose a novel approach whereby the IO system is viewed as a network, the topology of which is transformed with the addition of virtual nodes so that available empirical flow data can be mapped directly to existing links, with no additional estimation required, and no impact on results. As IO systems become increasingly disaggregated, and coupled to adjacent databases and models, the adaptability of IO frameworks becomes increasingly important. We show that topological transformations also offer large advantages in terms of transparency, modularity and increasingly importantly for global IO models, efficiency. We illustrate the results in the context of trade linking, multi-scale integration and other applications.     

Contextualizing the subjectivist-objectivist debate in entrepreneurship using engineering,art, craft,and bricolage

The debate regarding the degree to which opportunities and resources are social constructions risks stagnation because it is difficult to argue that opportunities are either entirely constructed or entirely objective. In this paper we seek to contribute to this debate by introducing some overlooked aspects of the work of Lévi-Strauss (1962) as they relate to the discussion of entrepreneurial opportunities and resources. A categorization scheme of entrepreneurs based on Lévi-Strauss’ categories of art, craft, engineering and bricolage can be used to help differentiate the ways in which entrepreneurs view opportunities and resource acquisition, and how those views impact entrepreneurial action and ultimately entrepreneurial success. This contrasts with the more traditional entrepreneurship literature, which views opportunities as objective phenomena and opportunity identification and exploitation as completely rational.     

SEC interventions and the frequency and usefulness of non-GAAP financial measures

This paper examines the effect of two Securities and Exchange Commission regulatory interventions related to disclosure of non-GAAP financial measures. There are three main results. First, the probability of disclosure of non-GAAP earnings declines in 2003, but the probability of disclosure of other non-GAAP financial measures has an accelerated decline after the first intervention. Second, all else equal, after Regulation G, investors have a positive market reaction to the disclosure of non-GAAP earnings. Finally, investors react to the adjustments made by I/B/E/S financial analysts as they do to the GAAP surprise, but they do not react to the additional adjustments made by firms.     

Corporate environmental sustainability reporting in the context of national cultures: A quantile regression approach

This work, based on previous evidence within international business management research, aims to test the influence of communities’ culture features on corporate environmental sustainability reporting (CESR) practices. To overcome some limitations of conventional statistical approaches applied by previous research, a quantile regression (QR) model is implemented which allows setting a framework to test the working hypotheses in different scenarios that cover divergent firms’ commitment levels to stakeholder engagement and CESR practices development. Our central results addresses that different national culture dimensions present a non-monotonic influence on CESR practices. This result, which is analyzed through the Stakeholder Theory proposals, can be explained because corporate sustainability behaviors are highly sensitive to stakeholders’ pressures and demands which are ultimately conditioned by the cultural environment. Some interesting recommendations for companies’ strategic management and governmental policy-making processes are reported.     

Are workplaces with many women in management run differently?

Are workplaces with a high percentage of women in management run differently? This paper uses data from the British 1998 Workplace Employee Relations Survey (WERS98) to analyze empirically the relationship between the percentage of female workplace managers and people-management practices. The results show that workplace management teams with a higher proportion of women monitor employee feedback and development more intensely. Such teams also tend to promote more interpersonal channels of communication and more employee participation in decision-making, although the evidence is weaker for these last two practices. Overall, the findings suggest that the concept of good workplace management practices converges on female leadership styles when the percentage of female managers increases.
