We study the optimal dynamic portfolio exposure to predictable default risk, taking inspiration from the search for yield by means of defaultable assets observed before the 2007–2008 crisis and in its aftermath. Under no arbitrage, default risk is compensated by an ‘yield pickup’ that can strongly attract aggressive investors via an investment-horizon effect in their optimal non-myopic portfolios. We show it by stating the optimal dynamic portfolio problem of Kim and Omberg (Rev Financ Stud 9:141–161, 1996) for a defaultable risky asset and by rigorously proving the existence of nirvana-type solutions. We achieve such a contribution to the portfolio optimization literature by means of a careful, closed-form-yielding adaptation to our defaultable asset setting of the general convex duality approach of Kramkov and Schachermayer (Ann Appl Probab 9(3):904–950, 1999; Ann Appl Probab 13(4):1504–1516, 2003).  相似文献

Using a three-phase approach that combines quantitative (pooled OLS, fixed effects and IV) with qualitative (semi-structured interviews) analyses, we find that in Italy, workplace unions are more likely to enhance training when they sign a firm-level agreement and when they can get access to external funds for financing. We also identify three channels: what we call a ‘maturation effect’, double-track communication and watch-dog function. We argue that these results are consistent with the idea that the impact of workplace unions on training depends on the empowerment of its collective voice within an institutional framework that does not fit either of the standard models provided by collective and liberal market economies.  相似文献

This article explores a stage in the capitalist transformation of the Czech Republic in early 1993. Three levels of change are examined: institutional developments in industrial relations; perceptions of change among union policy makers; and attitudes and experiences of managers and workers at workplace level.  相似文献

In the Czech Republic and elsewhere in the region, researchers have noted the widespread adoption of the multi-divisional form (MDF) by the former state-owned enterprises. In contrast to the accepted explanations in western capitalist societies, the spread of the MDF in post-Communist economies has had little or nothing to do with growth strategies such as diversification. Developing ideas from the existing western literature, the paper examines the role of economic, institutional and strategic choice factors in three large, former state enterprises within the Czech post-Communist context. The findings suggest that all three factors are theoretically important, but neither equally nor independently so. In particular, economic factors acted as a major constraint on structural choice only under extreme conditions, while institutional factors and strategic choice are best understood as interdependent moments in a recursive process of structural enactment.  相似文献

In the last decade, the demand for sustainable and social investments has improved. The mutual funds industry has responded to market needs by offering a number of investment products focused on Environmental, Social and Governance (ESG) companies. The aim of this article is to understand if an ESG score can actually be considered a valid criterion that portfolio managers could adopt, along with traditional risk–return optimisation, in selecting asset portfolios. The paper analyses the link between the performance and the ESG score of different sectoral portfolios (one for each sector of the Global Industry Classification Standard), entirely composed of ESG assets, in the search for a clear and strong positive correlation that could suggest an overall advantage to focus on an ex ante choice of assets with high ESG scores.  相似文献

This paper aims at contributing to the debate on the future of institutional economics and of the field as a whole by starting from the literature that discusses the relationship between Old‐Original Institutional Economics and New Institutional Economics. It suggests that the process of reunifying OIE and NIE (and evolutionary economics) prompted by part of the literature could be improved by the contribution of the Cognitive Institutional Economics. The paper follows a two‐stage pathway: first, it frames the debate on the relationships between NIE and the OIE and it concentrates on a subset of the literature that shows that NIE's recent developments complicate the distinction between NIE and OIE, and it explores the possibility that NIE and OIE may merge so that an amalgam of NIE, OIE and Evolutionary Economics becomes the next economic paradigm. Secondly, the paper argues that a step forward in the direction outlined by the literature has been made by CIE, which is a research stream that developed from cross‐fertilization among NIE, OIE and the Hayekian contributions to the analysis of institutions. In the concluding remarks, the possible emergence of a single institutional paradigm is discussed in the light of the literature about change in economics.  相似文献

This paper contributes to research on inter-organizational relationship dynamics by applying a dialectical approach. We analyze a situation where the relationship parties have divergent understandings of business exchange, and use a longitudinal, in-depth single case study method to investigate their interaction process. The case study focuses on the relationship between a customer and a supplier in the ferrochrome industry, using the acquisition of the supplier as the trigger of the relationship change process. The paper contributes to studies on relationship dynamics by showing how dynamics of inter-organizational relationships may result from struggles when parties’ interests and goals do not align with existing relationship arrangements. In particular, we focus on the process of (re)construction of the relationship and its linkage to the structural properties of the relationship.  相似文献

We study procurement bribery utilizing survey data from 11,000 enterprises in 125 countries. About one-third of managers report that firms like theirs bribe to secure a public contract, paying about 8 % of the contract value. Econometric estimations suggest that national governance factors, such as democratic accountability, press freedom, and rule of law, are associated with lower bribery. Larger and foreign-owned firms are less likely to bribe than smaller domestic ones. But among bribers, foreign and domestic firms pay similar amounts. Multinational firms appear sensitive to reputational risks in their home countries, but partially adapt to their host country environments.  相似文献
