A common backstop to the Single Resolution Fund

During the establishment of the Banking Union it has been agreed to develop a common backstop to the Single Resolution Fund. The following key principles constitute the point of departure of this paper:

1. Fiscal neutrality in the medium term;

2. Instrument of last resort;

3. Equivalent treatment across all Member States in the Banking Union; and

4. No costs for non-Banking Union Member States.

For each aspect the legal and regulatory background as well as the economic implications are provided. They significantly influence the common backstop’s final design and the choice of an adequate provider for the steady state.     

Managerial optimism and investment choice

This paper analyzes whether it might be desirable for a firm to hire an overoptimistic manager to commit to a certain R&D strategy. I consider a Cournot model with an ex‐ante R&D stage where firms can invest in cost reduction before product market competition takes place. I show that firms want to hire overoptimistic managers and argue that a manager's type may serve as a substitute for strategic delegation via contracts. Copyright © 2010 John Wiley & Sons, Ltd.     

Supplier Portfolio Management for IT Services Considering Diversification Effects

By means of service-oriented architectures the IT support of processes can be designed as a portfolio of individual IT services provided by different suppliers. The processes are designed based on selection decisions between IT services that potentially have to be included. Many companies formulate a multitude of requirements for investments in IT services at ever shorter intervals. However, the scope of the desired investments usually exceeds the available budget. Thus, companies face the challenge of allocating the limited budget to investments in the most promising combination of IT services. This is hardly possible without methodical support. In addition, the allocation is often done intuitively and subject to the decision-makers’ affinity with IT. Therefore, this paper develops a quantitative, multi-period procedure model for the purpose of maximizing the enterprise value in accordance with value based management, which considers the dependencies of the periodical selection decisions. In the following, a decision logic for the heuristic solution to the selection problem is presented and its application is demonstrated by means of an illustrative case example.

A temporal analysis of how entrepreneurial goal intentions,positive fantasies,and action planning affect starting a new venture and when the effects wear off

The road from intentions to actions and new venture creation is long. So far, the literature has provided insights into action-regulatory factors that contribute to new venture creation. However, the literature has neglected to take into account the temporal dynamics underlying these relationships. We contribute to action-regulation theories in entrepreneurship by theorizing about and investigating how the effects of action-regulatory factors hold over time. We hypothesize that the action-regulatory factors of entrepreneurial goal intentions, positive fantasies, and action planning have combined effects on new venture creation. Furthermore, we hypothesize that these effects become weaker over time. To test our hypotheses, we studied 96 Ugandan entrepreneurs over 30 months. Our results supported our hypotheses. Action planning moderated the effects of entrepreneurial goal intentions and positive fantasies on new venture creation. Furthermore, the effects were significant in the beginning and wore off over time. Our study shows that including a time frame in theoretical models is important to derive valid conclusions from empirical results and to develop more precise theories.     

The determinants of recovery rates in the US corporate bond market

We examine recovery rates of defaulted bonds in the US corporate bond market, based on a complete set of traded prices and volumes. A study of the trading microstructure around various types of default events is provided. We document temporary price pressure with high trading volumes on the default day and the following 30 days, and low trading activity thereafter. Based on this analysis, we determine market-based recovery rates and quantify various liquidity measures. We study the relation between the recovery rates and these measures, considering additionally a comprehensive set of bond characteristics, firm fundamentals, and macroeconomic variables.     

Expanding Insights on the Diversity Climate–Performance Link: The Role of Workgroup Discrimination and Group Size

The present study extends knowledge of the performance consequences of workgroup diversity climate. Building upon Kopelman, Brief, and Guzzo's ( 1990 ) climate model of productivity, we introduce workgroup discrimination as a behavioral mediator that explains the positive effects of diversity climate on workgroup performance. In addition, we investigate group size as a moderator upon which this mediated relationship depends. We test these moderated‐mediated propositions using a split‐sample design and data from 248 military workgroups comprising 8,707 respondents. Findings from structural equation modeling reveal that diversity climate is consistently positively related to workgroup performance and that this relationship is mediated by discrimination. Results yield a pattern of moderated mediation, in that the indirect relationship between workgroup diversity climate (through perceptions of workgroup discrimination) and group performance was more pronounced in larger than in smaller workgroups. These results illustrate that discrimination and group size represent key factors in determining how a diversity climate is associated with group performance and, thus, have significant implications for research and practice. © 2014 Wiley Periodicals, Inc.
