Auf festem Fuß ins hohe Alter

Zusammenfasung  Qigong mit Senioren — Bei der Pflege ?lterer Menschen steht meist nicht die Wiederherstellung im Sinne von Heilung im Mittelpunkt, sondern die Erhaltung der K?rperfunktionen. Denn funktionelle Einschr?nkungen ?lterer Patienten sind in einem erstaunlichen Umfang reversibel oder zumindest kompensierbar. Bew?hrt haben sich hier auch komplement?re Methoden.     

The effect of banking regulation on cross-border lending

Banking regulations often differ between countries: Some regulators require banks to document their evaluation of firms’ creditworthiness, which determines the banks’ choice of lending technology. In a theoretical model, we study how differences in regulation influence competition between domestic and foreign banks and analyze the effect of regulatory harmonization on cross-border lending. We predict that lending rates are lower and access to credit is easier for firms in a border region if the national regulations differ. Using unique bank- and firm-level data from Germany, we show that firms in a border region have better access to credit if regulation differs.     

Bank Competition and Collateral: Theory and Evidence

We investigate the impact of bank competition on the use of collateral in loan contracts. We analyze asymmetric information about the borrowers’ type in a Salop model in which banks choose between screening the borrower and asking for collateral. We show that the presence of collateral is more likely when bank competition is low. We then test this prediction empirically on a sample of bank loans from 70 countries. We perform logit regressions of the presence of collateral on bank competition, measured by the Lerner index. Our empirical tests corroborate the theoretical predictions that bank competition reduces the presence of collateral. These findings survive several robustness checks.     

The political economy of corruption and the role of economic opportunities1

In many developing and transition countries, we observe rather high levels of corruption. We argue that the missing political support for anti‐corruption policies is due to a lack of economic and financial reforms. Our model is based on the fact that corrupt officials have to pay entry fees to get lucrative positions. In a probabilistic voting model, we show that this, together with the lack of economic opportunities, makes anti‐corruption policies less likely. Compared to a reformed economy, more voters are part of the corrupt system and, more importantly, rents from corruption are distributed differently. Economic liberalization increases the support for anti‐corruption measures. The additional effect of financial liberalization is ambiguous.     

Challenges on the way to stage three of European Monetary Union

While the Maastricht Treaty envisages a single European Currency as part of the Economic and Monetary Union, it contains no detailed instructions as to the practical arrangements for its introduction. Despite prolonged discussions and negotiations at various levels, no consensus has so far been achieved on the optimum changeover procedure. This article deals with some of the major challenges in this context.     

A general HJM framework for multiple yield curve modelling

We propose a general framework for modelling multiple yield curves which have emerged after the last financial crisis. In a general semimartingale setting, we provide an HJM approach to model the term structure of multiplicative spreads between FRA rates and simply compounded OIS risk-free forward rates. We derive an HJM drift and consistency condition ensuring absence of arbitrage and, in addition, we show how to construct models such that multiplicative spreads are greater than one and ordered with respect to the tenor’s length. When the driving semimartingale is an affine process, we obtain a flexible and tractable Markovian structure. Finally, we show that the proposed framework allows unifying and extending several recent approaches to multiple yield curve modelling.     

Economic impact of industry-sponsored clinical trials of pharmaceutical products in Austria

Abstract

Aims: Modern pharmaceutical product development is a long and complex process associated with significant investments by pharmaceutical companies. The innovative pharmaceutical industry accounts for the vast majority of expenditures in clinical trials of potential new pharmaceuticals and therefore generates economic activity within a country. The aim was to assess the far-reaching economic impact of industry-sponsored clinical-trials (ISCTs) of pharmaceutical products for the healthcare system and the national economy.

Materials and methods: The study approach was based on three analytical steps. First, a survey among 15 pharmaceutical companies in Austria was conducted to evaluate the annual number of ISCTs subdivided according to trial phase, therapeutic areas and associated employees. Second, the monetary value of treatments performed in ISCTs was calculated based on a sample of clinical-trial protocols. Finally, the macroeconomic impact, measured in terms of value-added and jobs created by the conducted ISCTs, was calculated using Input–Output analysis by applying an extended Leontief-model.

Results: The study demonstrated that €116.22 million spent in ISCTs generated a total value added of €144 million, €74 million direct, in 2018. Each year a medical treatment value of €100 million was financed through 463 ISCTs, with an average value of medical treatment of €37,068 per recruited patient. This represents a significant 0.3% of annual current health-expenditures. In summary, each Euro invested by the pharmaceutical industry in ISCTs generates €1.95 for the Austrian economy. ISCTs also created and secured employment in the extent of 2,021 full-time-equivalents, thus resulting in an employment multiplier of 1.66.

Conclusions: In conclusion, conducting clinical-trials by pharmaceutical industry—beside its importance in its own domain—results in tangible benefits and a positive macroeconomic impact that contribute to the sustainability of the Austrian healthcare system by complementing its limited resources. Furthermore, it is a non-negligible factor in locational and industrial policy.     

Effects of bank insolvency on corporate incentives in transition economies

In transition countries, the real impact of banking crises has so far been rather moderate. We study the effect of bank insolvency on corporate incentives in a model where incumbent banks possess an informational advantage. We find that bank insolvency reduces the incentive to restructure for firms whose incumbent bank becomes insolvent. However, bank insolvency provides an additional incentive for firms that enter the credit market to develop new projects because it reduces asymmetric information between banks. Firms’ credit costs are thereby lowered. We also explain a path‐dependent development by demonstrating that the firms’ decision to develop new projects depends on the banks’ share of non‐performing loans.     

Polynomial processes and their applications to mathematical finance

We introduce a class of Markov processes, called m-polynomial, for which the calculation of (mixed) moments up to order m only requires the computation of matrix exponentials. This class contains affine processes, processes with quadratic diffusion coefficients, as well as Lévy-driven SDEs with affine vector fields. Thus, many popular models such as exponential Lévy models or affine models are covered by this setting. The applications range from statistical GMM estimation procedures to new techniques for option pricing and hedging. For instance, the efficient and easy computation of moments can be used for variance reduction techniques in Monte Carlo methods.
