International Environmental Agreements,Fiscal Federalism,and Constitutional Design

In this paper, we analyze how the prospect of international negotiations over trans‐boundary pollution shapes intracountry transfer schemes when the governments of the countries' polluting regions are in charge of environmental policy and negotiations. Federal governments can implement compensation payments between domestic regions and matching grants prior to the international negotiations between the polluting regions. The subgame‐perfect transfer schemes fail to fully internalize the environmental externality, leading to an inefficient international environmental agreement. As the international spillover increases, the intracountry compensation rates increase while the matching rates decline, distorting the incentives for the regional governments in opposing directions. We also show that decentralization of environmental decision making arises endogenously.     

Conditional performance evaluation for German equity mutual funds

We investigate the conditional performance of a sample of German equity mutual funds over the period from 1994 to 2003 using both the beta-pricing approach and the stochastic discount factor (SDF) framework. On average, mutual funds cannot generate excess returns relative to their benchmark that are large enough to cover their total expenses. Compared to unconditional alphas, fund performance sharply deteriorates when we measure conditional alphas. Given that stock returns are to some extent predictable based on publicly available information, conditional performance evaluation raises the benchmark for active fund managers because it gives them no credit for exploiting readily available information. Underperformance is more pronounced in the SDF framework than in beta-pricing models. The fund performance measures derived from alternative model specifications differ depending on the number of primitive assets taken to calibrate the SDF as well as the number of instrument variables used to scale assets and/or factors.     

Digitalisierung im Gesundheitswesen — zwischen Datenschutz und moderner Medizinversorgung

The digital transformation of the healthcare branch is important and unstoppable. The enormous possibility of digitalisation to redesign and enhance processes has been shown in other branches. Digital technologies offer the similarly large potential to improve the quality and efficiency of healthcare services. However, in terms of digitalisation, the German health system lags behind other European countries. But given a lack of available evidence, the effects of the digitalisation of the healthcare system cannot be reliably evaluated. Digital access to patient data necessitates constructive error cultures in organisations in order to limit defensive medicine. And digital access to health information necessitates individual competence in searching and using this information for participatory decision-making. As with all technological progress, information security is very important in order to gain citizens’ confidence in a digital healthcare system. Thus, it is necessary to simultaneously pursue both enhanced privacy standards and state-of-the-art medical technology.     

TRADE INTEGRATION,OUTSOURCING AND EMPLOYMENT IN AUSTRIA: A DECOMPOSITION APPROACH

Outsourcing and trade integration of advanced countries is debated with respect to employment effects, in particular for low educated workers – at least in relative terms. We study the employment effects – differentiated by educational attainment levels – of changes in the patterns of trade integration and outsourcing in the Austrian economy over the periods 1995–2000 and 2000–2005 using hierarchical decomposition analysis based on deflated input–output tables. Outsourcing is modeled as changes in the shares of domestically produced intermediates in total intermediates. A similar decomposition of the final demand vector allows us to draw conclusions on the overall employment effects of trade integration. The results suggest that the expected negative employment effects of outsourcing and rising import penetration have been overcompensated by increasing exports. Thus, the overall employment effects of Austrian trade integration have been positive for all educational attainment groups. However, whereas the total effects have been strongest for medium and high educated workers over the period 1995–2000, employment of low educated workers have been strongest and positively affected over the period 2000–2005. This pattern can be explained by a more sluggish export performance together with stronger negative effects of outsourcing and import penetration in medium and high-skill intensive products.     

Advancing into the 21st Century: Visions and Challenges Facing the Downunder Economy

Long-term visions serve to focus on essentials for sustained economic and social welfare. We now have to face up to the challenge of globalisation (growing international capital mobility), at a time when we are undoing our historic, self-imposed protectionism. This also creates new opportunities, in particular in the dynamic Asia-Pacific economies.
There still is a 'window of opportunity' before an aging population will become a dominant problem. In the next 25 years, business will have to cope with high real interest rates and major uncertainties that now surround environmental policies.
If we are to take on these challenges in constructive and beneficial ways, we have to develop an institutional order that enables the utilisation of knowledge by enterprising people. This requires a simple, transparent and reliable legal and regulatory framework, which supports competitive market processes, and the defence of openness to international trade and capital flows against particular interest groups.
It seems plausible that the Downunder economy can grow over the next 25 years at about 3.5 per cent per capita if the right institutional conditions are created. If we fail to do so, a growing share of the capital, the skills and the enterprise made Down-under will move to offshore locations which encourage a better use of knowledge and capital by enterprising people. This would deprive many of economic opportunity. The central challenge therefore is to develop a system of government and labour relations which makes the Downunder economy internationally attractive.     

A Benchmark Approach to Filtering in Finance

The paper proposes the use of the growth optimal portfolio for pricing and hedging in incomplete markets when there are unobserved factors that have to be filtered. The proposed filtering framework is applicable also in cases when there does not exist an equivalent risk neutral martingale measure. The reduction of the variance of derivative prices for increasing degrees of available information is measured. 1991 Mathematics Subject Classification: primary 90A09; secondary 60G99; 62P20 JEL Classification: G10, G13
