Enhanced machine learning methods provide an encouraging alternative to forecast asset prices by extending or generalizing the possible model specifications compared to conventional linear regression methods. Even if enhanced methods of machine learning in the literature often lead to better...

This paper studies the dependence between coupled lives, i.e., the spouses' dependence, across different generations, and its effects on prices of reversionary annuities in the presence of longevity risk. Longevity risk is represented via a stochastic mortality intensity. We find that a...

The authors propose a new method for estimating the power-law exponents of firm size variables. Their focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. On the one hand, as is well known a firm size variable follows a power-law...

The purpose of the paper is to discuss ten things potential users should know about the limits of the Dynamic Conditional Correlation (DCC) representation for estimating and forecasting time-varying conditional correlations. The reasons given for caution about the use of DCC include the...

The paper shows that an IMF-like coinsurance arrangement among countries can play a useful role in the global financial system. The operation of the coinsurance arrangement is examined under different loan contracts. It shows that, if the IMF?s objective is to safeguard its resources and be...

Eine Untersuchung des ifo Instituts zeigt, dass schon die Hartz-Reformen durch den Abbau der Arbeitslosigkeit zu einer Verringerung der Ungleichheit auf dem Arbeitsmarkt geführt haben. Selbst bei ausschließlicher Betrachtung der Beschäftigten zeigt sich eine deutliche Trendwende um das Jahr...

Deutschland ist ein Land, das kräftig von oben nach unten umverteilt, innerhalb von Haushalten, durch Steuern und Transfers sowie auch durch die Bereitstellung öffentlicher Güter: In kaum einem anderen Land ist die Differenz zwischen der Ungleichheit der Brutto- und Nettoeinkommen größer...
