A nonparametric Data Envelopment Analysis (DEA) is performed on hospitals in the federal state of Saxony (Germany) and in Switzerland. This study is of interest from three points of view. First, contrary to most existing work, patient days are not treated as an output but as an input. Second,...

Internationale Vergleiche von Krankenhausleistungen sind bislang selten. Die vorliegende Analyse untersucht die Effizienz der Krankenhäuser in Sachsen und der Schweiz mittels der Data Envelopment Analysis (DEA), einem Verfahren zur Ermittlung der effizienten Grenze. Dabei wird im Sinne eines...

We investigate the consistency of efficiency scores derived with two competing frontier methods in the financial economics literature: Stochastic Frontier and Data Envelopment Analysis. We sample 34,192 observations for all German universal banks and analyze whether efficiency measures yield...

We address the problem how to estimate default probabilities for sovereign countries based on market data of traded debt. A structural Merton-type model is applied to a sample of emerging market and transition countries. In this context, only few and heterogeneous default probabilities are...

The Italian and German banking systems shared similar characteristics early in the 1990s but have evolved in different directions since then: Italy privatized its publicly-owned banks while Germany has maintained a large share of state-owned savings banks. Contemporaneously, banks in both...

We use a compound option-based structural credit risk model to infer a term structure of banking crisis risk from market data on bank stocks in daily frequency. Considering debt service payments with different maturities this term structure assigns a separate estimator for short- and long-term...

This paper investigates contagion effects. In a model with highly and lowly informed investors we show that a currency crisis in one country can trigger a crisis in another country. Portfolio losses of the highly informed investors in one country will force them to withdraw capital from the...

Gesundheitsökonomen nehmen Stellung zu den „Eckpunkten zu einer Gesundheitsreform“ der Koalitionsparteien vom 4. Juli 2006.

To clarify the causal links between financial activity and economic growth, three theoretical models are analyzed and a structural equation path models is estimated. In the modeling part, poverty traps result from large fixed costs or high proportions of real investment to run a financial...

An endogenous growth model with a financial sector is formulated, and empirical analyses are conducted. The model exhibits structural shifts and breaks caused by institutional change, suggesting that a linear approach is inadequate. To address this point empirically, we fit data for 90 countries...
