The Austrian Severance Pay Reform: Toward a Funded Pension Pillar

With the beginning of 2003 a new severance pay scheme was introduced in Austria. The reform extends the coverage of the scheme to all employees, and moves it to full and enterprise external funding, but average payments will be lower than previously. This paper provides some evidence on two explicit aims of the reform, namely to generate more fairness in the distribution of severance payments among employees and the creation of a basis of the underdeveloped second pillar of the Austrian pension system. The empirical analysis based on a cross section of completed job spells of different durations indicates that differences in payments among groups will be stronger in the new scheme compared to the old system. Based on retirement income projections and simulations of a multi-pillar pension reform for the blue and white collar workers’ pension system, we conclude that, an increase of the contribution rate would be necessary to achieve a sufficient second pillar retirement income.

Can Darwinism be ��Generalized�� and of what use would this be?

It has been suggested that, by generalizing Darwinian principles, a common foundation can be derived for all scientific disciplines dealing with evolutionary processes, especially for evolutionary economics. We show, however, that in the development of evolutionary biology, the abstract principles of so-called “Generalized Darwinism” have not been crucial for distinguishing Darwinian from non-Darwinian approaches and, hence, cannot be considered genuinely Darwinian. Moreover, we wonder what can be gained by invoking the abstract principles of Generalized Darwinism given that they do not suffice to substantiate an explanation of actual evolutionary processes. To that end, specific hypotheses are required. They neither follow from the suggested abstract principles, nor are they more easily found on that basis. Accordingly, we find little evidence in the literature for the claim that generalized Darwinian principles enhance the explanatory power of an evolutionary approach to economics.     

On the feasibility of a regional exchange rate system for East Asia: Lessons of the 1992/1993 EMS crisis

This paper argues that a regional exchange rate system such as the EMS should not be ruled out when discussing monetary options for East Asia. The paper recalls that the 1992/1993 EMS crisis was the crisis of an exchange rate system and not just the collapse of unilateral pegs pursued by individual countries. It discusses distinct features that add to the credibility of regional exchange rate systems and reasons that a system that is built around well-defined rules and which is managed very carefully and cooperatively according to those rules could be both credible and sustainable even in the 21st century.     

Supplier Portfolio Management for IT Services Considering Diversification Effects

By means of service-oriented architectures the IT support of processes can be designed as a portfolio of individual IT services provided by different suppliers. The processes are designed based on selection decisions between IT services that potentially have to be included. Many companies formulate a multitude of requirements for investments in IT services at ever shorter intervals. However, the scope of the desired investments usually exceeds the available budget. Thus, companies face the challenge of allocating the limited budget to investments in the most promising combination of IT services. This is hardly possible without methodical support. In addition, the allocation is often done intuitively and subject to the decision-makers’ affinity with IT. Therefore, this paper develops a quantitative, multi-period procedure model for the purpose of maximizing the enterprise value in accordance with value based management, which considers the dependencies of the periodical selection decisions. In the following, a decision logic for the heuristic solution to the selection problem is presented and its application is demonstrated by means of an illustrative case example.     

Measuring prior sensitivity and prior informativeness in large Bayesian models

In large Bayesian models, such as modern DSGE models, it is difficult to assess how much the prior affects the results. This paper derives measures of prior sensitivity and prior informativeness that account for the high dimensional interaction between prior and likelihood information. The basis for both measures is the derivative matrix of the posterior mean with respect to the prior mean, which is easily obtained from Markov Chain Monte Carlo output. We illustrate the approach by examining posterior results in the small model of Lubik and Schorfheide (2004) and the large model of Smets and Wouters (2007).
