Full currency convertibility in Eastern Europe?

In the countries of Eastern Europe the question as to the degree of currency convertibility is among the most important decisions to be taken when setting the framework for a free market economy. This article attempts to indicate the monetary and fiscal measures that will be required if the reform countries willing and able to be integrated into the EC and OECD are to proceed rapidly to the liberalisation of capital transactions.     

Community engineering for innovations: the ideas competition as a method to nurture a virtual community for innovations

'Crowdsourcing' is currently one of the most discussed key words within the open innovation community. The major question for both research and business is how to find and lever the enormous potential of the 'collective brain' to broaden the scope of 'open R&D'. Based on a literature review in the fields of Community Building and Innovation Management, this work develops an integrated framework called 'Community Engineering for Innovations'. This framework is evaluated in an Action Research project – the case of an ideas competition for an ERP Software company. The case 'SAPiens' includes the design, implementation and evaluation of an IT-supported ideas competition within the SAP University Competence Center (UCC) User Group. This group consists of approximately 60,000 people (lecturers and students) using SAP Software for educational purposes. The current challenges are twofold: on the one hand, there is not much activity yet in this community. On the other, SAP has not attempted to systematically address this highly educated group for idea generation or innovation development so far. Therefore, the objective of this research is to develop a framework for a community-based innovation development that generates innovations, process and product ideas in general and for SAP Research, in particular, combining the concepts of idea competitions and virtual communities. Furthermore, the concept aims at providing an interface to SAP Human Resources processes in order to identify the most promising students in this virtual community. This paper is the first to present an integrated concept for IT-supported idea competitions in virtual communities for leveraging the potential of crowds that is evaluated in a real-world setting.     

Why Are Mothers Working Longer Hours in Austria than in Germany? A Comparative Microsimulation Analysis*

Labour force participation rates of mothers in Austria and Germany are similar; however, full‐time employment rates are much higher among Austrian mothers. In order to find out to what extent these differences can be attributed to differences in the tax‐transfer system, we perform a comparative microsimulation exercise. After estimating structural labour supply models for both countries, we interchange two important institutional characteristics of the two countries ‐ namely, (i) the definition of the tax unit within the personal income tax and (ii) the parental leave benefit scheme. As our analysis shows, differences in mothers’employment patterns can partly be explained by the different tax systems: while Germany has a system of joint taxation with income splitting for married couples, Austria taxes everyone individually, which leads to lower marginal tax rates for secondary earners than in the German system.

Optimal price and advertising policy for new products

Extending a model originally proposed by Bass, a “diffusion model” is developed that allows us to investigate the effects of certain price and advertising strategies during and after the introduction of new products by means of numerical computer simulation. The distinction between “innovators” and “imitators” forms the core of the model. A wide variety of implications for marketing strategies is derived.
