Are multinational teams more successful?

Teams have become increasingly multinational in many sectors. The impact of national diversity on team performance is, however, controversial. On the one hand, multinational teams may have access to a greater variety of task-relevant expertise, which should increase the team performance. On the other hand, national diversity may complicate team collaboration and increase team conflict. Applying panel econometrics to 4284 team observations in a globalized sector, we find evidence that multinational teams perform worse than teams with less national diversity.     

What determines the composition of banks’ loan portfolios? Evidence from transition countries

This paper explores how bank characteristics and the institutional environment influence the composition of banks’ loan portfolios. We use a new and unique data set based on the EBRD Banking Environment and Performance Survey (BEPS), which was conducted for 220 banks in 20 transition countries. We show that bank ownership, bank size, and legal creditor protection are important determinants of the composition of banks’ loan portfolios. In particular, we find that foreign banks play an active role in mortgage lending. Moreover, banks that perceive pledge and mortgage laws to be of high quality choose to focus more on mortgage lending.     

The Impact of Sexual Harassment Policy in the Dutch Police Force

The aim of the present study was to evaluate the outcome of sexual harassment policy in the Dutch Police Force. Using a survey, sexual harassment was measured in 2000 and again in 2006 and we tested whether sexual harassment is associated with the comprehensiveness of policies. To be able to identify divisions with comprehensive policies, we interviewed 29 key persons in semi-structured interviews. It appeared that between 2000 and 2006 sexual harassment did not decrease: neither for women nor for men. Furthermore, the risk of sexual harassment was not lower in divisions that implemented comprehensive policies than in divisions with less comprehensive policies. The results suggest that sexual harassment is a workplace hazard that is very difficult to prevent in male dominated workplaces and implementing a comprehensive policy is not sufficient to prevent this workplace hazard.     

Ein versicherungsmathematischer Ansatz zur Berechnung von Marktwerten der Deckungsrückstellung in der Lebensversicherung

Based on well-known actuarial calculation principles for the determination of the liabilities for life insurance contracts, we present a method for the calculation of fair values of liabilities. This method is consistent with the Solvency II requirements. The main principle is the discounting of probability weighted future cash flows, including assumptions on interest rates, costs and lapse for the calculation of actuarial present values. In addition to the mathematical framework, we discuss some numerical results that compare the traditional liabilities with the fair value approach. The presented principles are also relevant for the IFRS directives, which are at the moment available as exposure draft.     

Combining equilibrium,resampling, and analyst’s views in portfolio optimization

This paper proposes the use of a portfolio optimization methodology which combines features of equilibrium models and investor’s views as in Black and Litterman (1992), and also deals with estimation risk as in Michaud (1998). In this way, our combined methodology is able to meet the needs of practitioners for stable and diversified portfolio allocations, while it is theoretically grounded on an equilibrium framework. We empirically test the methodology using a comprehensive sample of developed countries fixed income and equity indices, as well as sub-samples stratified by geographical region, time period, asset class and risk level. In general, our proposed combined methodology generates very competitive portfolios when compared to other methodologies, considering three evaluation dimensions: financial efficiency, diversification, and allocation stability. By generating financially efficient, stable, and diversified portfolio allocations, our methodology is suitable for long-term investors such as Central Banks and Sovereign Wealth Funds.     

Scope versus speed: Team diversity,leader experience,and patenting outcomes for firms

Research Summary: How does the organization of patenting activity affect a firm's patenting outcomes? We investigate how the composition of patenting teams relates to both the scope of their patent applications and the speed with which their patents are approved, by examining the main effects of team members’ intra‐organizational diversity (based on affiliations with formal organizational units and informal organizational communities) and the moderating effects of team leader experience. We test our moderated mediation model in a sample of 121 teams that filed patents in a Fortune 50 company's India R&D center between 2005 and 2015, using proprietary employee data combined with newly released micro‐data from the U.S Patent and Trademark Office (USPTO). Our findings illuminate the micro‐foundations of innovation in firms by highlighting a trade‐off between organizing patenting activity to maximize scope versus speed. Managerial Summary: Patenting is an important strategic tool that firms can use to protect and create value from their innovations. A firm can benefit from filing a patent application that gives it a wider possible set of claims related to an innovation. It can also benefit from faster approval of a patent application by the Patent Office. However, our study shows that there is a trade‐off between patent application scope and patent approval speed, which creates tensions for the organization of patenting activities inside firms. In particular, we find that the diversity of a patenting team is positively related to patent scope but negatively related to patenting speed, and that these relationships vary with the experience of the team leader.     

Creative financing

By taxing or seeking donations from health care providers, states have increased federal matching to pay medicaid costs. The Bush Administration views the practice as a scam.     

Play and learn team building

In order to have a team function correctly, power must be distributed equally, with no team member having more perceived power than any other. It is this leveling of the playing field that allows the team to develop and to stimulate the creative juices of its members. This article discusses techniques that can help an organization break down the power barriers and permit its employees to become a cohesive unit--a team.
