ACQUISITION OF INFORMATION TO DIVERSIFY CONTRACTUAL RISK*

Are hedging transactions that diversify a manager’s compensation risk detrimental to incentives, or can they improve contracting efficiency? If hedging provides efficiency benefits, should the manager or the firm undertake it? In our model, both the firm and the manager can trade financial portfolios to diversify the manager’s compensation risk. Prior to the portfolio selection, the parties need to acquire information on how different financial portfolios fit their diversification purposes. We illustrate that financial portfolios correlated with firm‐specific risk improve contracting efficiency. For equal information costs, it is optimal for the firm to undertake the hedging on the manager’s behalf.     

Umgang mit Aggressionen

Herausforderndes Verhalten bei Demenz - Wenn Aggression, erh?hter Bewegungsdrang, starke Orientierungsprobleme, Selbst- und Fremdgef?hrdung oder andere „herausfordernde“ Verhaltensweisen auftreten, wird die Pflege und Begleitung von Demenzkranken als Belastung erlebt. Doch Pflegende stehen dem Problem nicht hilflos gegenüber. Eine interdisziplin?re Expertengruppe gibt mit ihren Empfehlungen ein Handlungsgerüst.     

Führen und Motivieren

Autorit?r ist out – Pflegefachkr?fte fehlen überall, aber auch der ?rztliche Nachwuchs ist inzwischen rar. Die ?ra der Patriarchen auf den Chefetagen der Krankenh?user geht zu Ende. Weil diese den Nachwuchs vergraulen und dem Ruf der Klinik schaden, besinnen sich Krankenh?user auf einen wertsch?tzenden, kollegialen und transparenten Führungsstil.     

Zur Reform der Pflegeversicherung: Einstieg in ein nachhaltiges und wettbewerbliches System

Frames und Positionen zur EU-Osterweiterung

While framing theory is concerned with the way media content is presented, news bias theory concentrates on the evaluative aspect. The study integrates both approaches of news structuring. A detailed argument analysis of two German quality newspapers, Die Welt and Frankfurter Rundschau, representative for two opposite editorial viewpoints, was conducted to test the assumptions of both theories. The examination of news coverage related to the accession of Poland, Czech Republic, Bulgaria and Romania to the EU contradicts previous results of framing and news bias research. Apart from finding a pronounced focus on economical topics in both newspapers, they clearly differ in their frames of reference and political positions on the issues, staying in line with their editorial orientation. A comparison of the different accession times reveals a change in the frames of reference and the advocates of these frames.     

Portfolio optimization based on GARCH-EVT-Copula forecasting models

This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to perform out-of-sample forecasts and simulate one-day-ahead returns for ten stock indexes. We construct optimal portfolios based on the global minimum variance (GMV), minimum conditional value-at-risk (Min-CVaR) and certainty equivalence tangency (CET) criteria, and model the dependence structure between stock market returns by employing elliptical (Student-$t$ and Gaussian) and Archimedean (Clayton, Frank and Gumbel) copulas. We analyze the performances of 288 risk modeling portfolio strategies using out-of-sample back-testing. Our main finding is that the CET portfolio, based on ARMA-GARCH-EVT-copula forecasts, outperforms the benchmark portfolio based on historical returns. The regression analyses show that GARCH-EVT forecasting models, which use Gaussian or Student-$t$ copulas, are best at reducing the portfolio risk.     

Sustainability practices of family firms: the interplay between family ownership and long-term orientation

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO.     

Budget deficits,money growth and inflation: the Turkish evidence

The paper investigates the long-run relationships between budget deficits, inflation and monetary growth in Turkey considering two alternative trivariate systems corresponding to the narrowest and the broadest monetary aggregates. While the joint endogeneity of money and inflation rejects the validity of the monetarist view, lack of a direct relationship between inflation and budget deficits makes the pure fiscal theory explanations illegitimate for the Turkish case. Consistent with the policy regime of financing domestic debt through the commercial banking system, budget deficits lead to a growth not of currency seigniorage but of broad money in Turkey. This mode of deficit financing, leading to the creation of near money and restricting the scope for an effective monetary policy, may not be sustainable, as the government securities/broad money ratio cannot grow without limit.     

Why Are U.S. Stocks More Volatile?

U.S. stocks are more volatile than stocks of similar foreign firms. A firm's stock return volatility can be higher for reasons that contribute positively (good volatility) or negatively (bad volatility) to shareholder wealth and economic growth. We find that the volatility of U.S. firms is higher mostly because of good volatility. Specifically, stock volatility is higher in the United States because it increases with investor protection, stock market development, new patents, and firm‐level investment in R&D. Each of these factors is related to better growth opportunities for firms and better ability to take advantage of these opportunities.
