I examine how an important attribute of financial reporting quality, i.e., accounting conservatism, affects the sensitivity of corporate bond returns to changes in the value of equity (i.e., the hedge ratio). The correlation between stock and bond returns (co‐movement) is a fundamental input for asset allocation decisions as it determines the diversification benefits of bonds relative to equities within an investment portfolio. According to structural models of credit risk, co‐movement should be generally positive, but lower when the risk of wealth transfers from bondholders to shareholders is severe. I find that firms that report conservative earnings and use covenants in their bond contracts exhibit on average stronger co‐movement. This result is consistent with conservatism providing bondholders with a credible and contractible signal that improves monitoring, thus preventing wealth transfers.  相似文献

This paper aims to aid our understanding of the emergence of accounting as a control instrument in complex proto-industrial settings, through its perceived capacity of mirroring the production process. The paper starts off from an archival document, the 1586 deliberation by the Venetian Senate, which imposed on the Arsenal a stocktaking to be conducted every three years, and ad hoc galley production accounts to be kept in double entry format, where the passage of materials and work-in-process between units were recorded both in physical quantity and value. In this deliberation the Venetian Senate was clearly posing explicitly the problem of costing and the efficient use of resources within the Arsenal. Until then, the Senate controlled this organisation only by limiting the funds allocated to activities (wages, oars, 'stuffs') without entering into the substance of the operations. Two interrelated investigations are carried out. First, a content analysis of the 1586 document is made. Second, the question of its 'impact' on the Arsenal's actual accounting practices is addressed. In a 1633 Report by Alvise Molin, a magistrate of the Republic, some elements of the 1586 deliberation seem to surface, insofar as a quite sophisticated calculation of the production costs of galleys is provided. In this sense it might well be that the notion of cost emerged as a sort of 'accidental by-product' of the Senate's efforts aimed at introducing tighter forms of control on the Arsenal.  相似文献

The authors analyse patterns of international trade and financial integration using complex network analysis. The combination of both binary and weighted approaches delivers more precise and thorough insights into the topological structure and properties of international trade and financial networks (ITN and IFN). It is found that the ITN is more densely connected than the IFN, while both types of network display a core–periphery structure. This hierarchical organization is more pronounced in financial markets, suggesting that the bulk of trade in financial assets occurs through a handful of countries acting as hubs. High-income countries are better linked and form groups of tightly interconnected nodes. This kind of structure can explain why the recent financial crisis has spread rapidly among advanced countries while reaching emerging markets only in a second phase.  相似文献

This paper focuses on a specific strategy that developers of mobile applications may use to stimulate demand: The release of updates. We develop a theoretical analysis that shows that developers have incentives to release updates when experiencing a drop in performance. The predictions of the model are then tested using an unbalanced panel of top 1,000 apps in iTunes and Google Play for five European countries. We estimate that while in iTunes the release of an update stimulates a 26% increase in download growth, in Google Play updates play a less significant role. This difference is partly due to systematic differences in apps and in developers operating in the two stores (“selection effect”), and partly to a lack of quality control on apps and updates in Google Play (“quality check effect”). These findings highlight the crucial importance of an appropriate management of updates as well as the relevance of institutional characteristics of the app stores.  相似文献

Network industries present several counterintuitive aspects. This peculiarity has attracted particular attention among policymakers, but public intervention has not always been irreproachable. A continuously improving appraisal of network industries tends to allow a better informed policy action and a good balance between otherwise potentially competing policies (competition policy and sector-specific regulation in the first place, but also innovation and standardization policies).  相似文献

This article discusses methodological issues related to language in advertising research. We introduce a framework that distinguishes between cross-linguistic research settings, where several languages are used in the study and different samples of respondents are studied in their own language, and multilingual research settings, where only a single language is used and multilingual respondents are studied either in their native or nonnative language. We review key principles that govern cross-linguistic and multilingual effects in advertising research to formulate guidelines for research design and data analysis. In the cross-linguistic context, these principles address nonuniform cross-linguistic differences in responses (related to nonequivalence of individual questionnaire items) versus uniform response effects (related to nonequivalence of verbal response category labels). In the multilingual context, we bring together evidence that shows how—even when comprehension is not a problem—stimuli, questions, and response categories may be processed differently in respondents' native versus nonnative language.  相似文献

The extraordinary global growth in the private funding of public infrastructure projects in the form of public‐private partnerships (or PPPs) is expected to have major social and economic benefits—benefits that result in large part from improving the allocation of project risks between the public and private sectors. But with the financial crisis and severe tightening of credit likely to limit the financing and delivery of new projects, both project participants and their financiers need to manage the technical, economic, legal, and political complexities of infrastructure projects more carefully, especially in less traditional infrastructure deals that involve complex operations, new assets, or emerging markets. This paper proposes and illustrates the application of the real options valuation approach to a critical feature of most PPPs: establishing the final “indemnification” amount to be paid by a public administration to private partners in the project financing of those PPPs that face substantial market risks. In demonstrating this approach, the authors use the case of the Pedemontana Lombarda toll road, a major transportation infrastructure project in Northern Italy for which financial plans have been filed and whose start is now pending. The main function of real options in this case is to capture the effects on value of the major market risk in such projects—namely, the uncertainty about volume of traffic on the new road. The authors interpret the final indemnification price as the value of a real put option sold by the awarding authority to private investors (in the case of a project that would otherwise be unprofitable and have a negative NPV). The put option takes the form of a clause in the concession contract that gives investors the right, under certain circumstances, to sell the toll road back to the government for a fixed sum (in this case, €2.9 billion). According to the authors, this valuation approach is likely to be helpful in any kind of infrastructure project that faces risk stemming from the unpredictability of market demand and future revenue streams.  相似文献

Using a sample of 4,122 project finance loans worth $769 billion arranged from 1991 to 2005, we demonstrate that certification by prestigious lead arranging banks creates economic value by reducing overall loan spreads compared to loans arranged by less prestigious arrangers. Banks participating in these loan syndicates, rather than the project sponsors, pay for this certification. They do so by allowing top tier arrangers to keep larger fractions of the upfront arranging fees. Results are robust to the correction for the endogenous choice of loans by prestigious arrangers and indicate that certification is even more valuable during periods of extreme financial stress.  相似文献

Schumpeter argued that boom and bust cycles are inherent to the rise of innovation and constitute an unavoidable consequence of the way the capitalist system reacts to the emergence of a wave of innovations. This contribution aims to describe Schumpeterian economic development in a ‘monetary theory of production’ framework, emphasizing the crucial role played by credit creation, conceived as ‘the monetary complement’ of innovation. By adopting a stock flow consistent analytical approach, we analyze both the structural change process triggered in the real economy by the emergence of innovation, and the monetary dynamics arising during the various stages of the development process.  相似文献

Abstract

Aims: The aim of this study was to conduct a cost-effectiveness analysis, as well as a budget impact analysis, on the use of apremilast for the treatment of adult patients with psoriatic arthritis (PsA), within the Italian National Health Service (NHS).

Methods: A Markov state transition cohort model, which was adapted to the Italian context, was used to compare the costs of the currently available treatments and of the patients’ quality of life with two alternative treatment sequences, with or without apremilast as pre-biologic therapy. Moreover, a budget impact model was developed based on the population of patients treated for PsA in Italy, who can be eligible for treatment with apremilast. The eligible population was represented by adult patients with PsA who had an inadequate response to or were intolerant to previous disease-modifying antirheumatic drugs (DMARDs), for the approved indication, and for the treatment studied in the economic analytic model.

Results: This cost-effectiveness analysis estimated that the strategy of using apremilast before biologic therapy is cost-effective, with an incremental cost-effectiveness ratio of €32,263.00 per QALY gained which is slightly over the normal threshold found in other Italian economic studies, which usually considers a 40-year-period. Conversely, the budget impact analysis was conducted over 3?years, and it led to an estimated annual saving of €1.6 million, €4.6 million and €5.5 million in the first, second and third year of apremilast commercialization, respectively, for a total saving of €11.75 million in 3?years.

Limitations: Limitations of this analysis include the absence of head-to-head trials comparing therapies included in the economic model, the lack of comparative long-term data on treatment efficacy, and the assumption of complete independence between the considered response rates to therapy.

Conclusion: The use of apremilast as a first option before the use of biologic agents may represent a cost-effective treatment strategy for patients with PsA who fail to respond to, or are intolerant to, previous DMARD therapy. In addition, based on a budget impact perspective, the use of apremilast may lead to cost savings to the Italian healthcare system.  相似文献
