Grenzen des Wettbewerbs im Gesundheitswesen
Ingmar Kumpmann
Sozialer Fortschritt,
2008
Abstract
Many health economists demand more competition in the health-care system. They focus on the competition between the individual health-insurance funds for those who want such insurance as well as on the competition between health-care providers for contracts with the health-insurance funds. However, they neglect the competition between health-care providers for patients; such competition is crucial for medical quality. This latter area of competition is in conflict with the two former ones. The empirical evidence on the effects of competition on cost and quality are also ambiguous. Thus, the mere appeal for „more competition“ does not do justice to the highly complex nature of the health-care system.

Abstract
Many health economists demand more competition in the health care system. They focus on the competition between sickness funds for insured and the competition between health care providers for contracts with sickness funds. But they neglect the competition between health care providers for patients which is crucial for medical quality. This third field of competition is in conflict with the two former fields. The empirical evidence concerning the effects of competition on cost and quality is also ambiguous. Thus the mere claim for “more competition” does not do justice to the high complexity of the health care system.

East German Economy: Demand Push Stronger than Structural Deficiencies
Wirtschaft im Wandel,
No. 7,
2007
Abstract
In 2006, growth of production was surprisingly strong in Eastern Germany. The structural deficiencies there would have suggested a slower pace. In particular, linkages with national and international business cycles have been underestimated. To a large part, the reason why output grew by 3 per cent did not come from Eastern Germany itself, but from the Old Länder and from abroad. In the New Länder, the strong upward swing in investment activity stimulated the economy. However, owing to a small increase in total income of private households, their purchasing power lagged behind.
The improved ability of East German firms to absorb cyclical impulses from exports and from Germany’s general investment activity proved to be a crucial factor. In particular, the endowment of workplaces with modern production facilities as well as the continued reduction in the disadvantages with respect to cost-competitiveness in the tradable goods sector were beneficial. The labour cost advantage compared to West German competitors increased further while the disadvantage compared to those from Central and Eastern Europe decreased.
Benefiting from these factors, economic activity in Eastern Germany will grow faster than in the Old Länder as long as the upswing in Germany and abroad remains strong. In 2007 and 2008, investments – especially in equipment – and exports will be the driving forces again. For exports, the strongly expanding markets in Central and Eastern Europe as well as in Russia will gain in importance. As income and employment prospects improve, private consumption will support the growth in production. Registered unemployment should decrease below the 1-million threshold.
Manufacturing will remain the primary force of the upswing; its advantages in production costs will not vanish as long as, even in presence of scarcity of skilled labour, salaries and wages do not increase more than in Western Germany. In the wake of robust economic growth, the New Länder will make further progress in catching up with respect to production and income.
Companies will regain support from the banking industry. Yet, investment capital still stems from public funding programmes to a non-negligible extent. In the medium run, access to credit will ease as a result of further improvements in the firms’ net worth position. However, dependency on internal funds remains high and exposes companies to comparatively strong cyclical risks. In an economic downturn, the structural deficiencies of the East German economy will impair economic expansion.

Implementing an International Lender of Last Resort
Tobias Knedlik
IWH Discussion Papers,
No. 20,
2006
Abstract
Current research discusses various general frameworks for installing an international lender of last resort (ILOLR). However, it remains unclear how the ILOLR should actually operate. This paper discusses six different options of construction of an ILOLR who supports central banks in the case of currency crises. The paper concludes that the cost efficient version of the ILOLR would be direct interventions by the IMF by the use of IMF resources and the right to dispose additional reserves from central banks. The paper considers measures of cost efficiency, such as cost of borrowing, intervention, and sterilization and moral hazard problems.

Das Grundeinkommen - Potenziale und Grenzen eines Reformvorschlags
Ingmar Kumpmann
Wirtschaftsdienst,
No. 9,
2006
Abstract
Currently the idea of introducing a Basic Income is politically debated. A Basic Income is “an income paid by a political community to all its members, without means test or consideration” (Vanderborght/Van Parijs). It would replace the existing tax and welfare schemes which guarantee the subsistence levels for all individuals. The Basic Income would prevent poverty, simplify the tax and social security system and disburden labour from the costs of social security. It would put an end to the highly problematic governmental controls concerning the ability and willingness of the unemployed to work. The main challenges of the proposal are the difficulty of funding and the danger of reduced labour incentives, problems which limit the possibility for implementing the model.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
No. 182,
2003
Abstract
The interbank money market plays a key role in the execution of monetary policy. Hence, it is important to know the functioning of this market and the determinants of the interbank money market rate. In this paper, we develop an interbank money market model with a heterogeneous banking sector. We show that besides for balancing daily liquidity fluctuations banks participate in the interbank market because they have different marginal costs of obtaining funds from the central bank. In the euro area, which we refer to, these cost differences occur because banks have different marginal cost of collateral which they need to hold to obtain funds from the central bank. Banks with relatively low marginal costs act as intermediaries between the central bank and banks with relatively high marginal costs. The necessary positive spread between the interbank market rate and the central bank rate is determined by transaction costs and credit risk in the interbank market, total liquidity needs of the banking sector, costs of obtaining funds from the central bank, and the distribution of the latter across banks.
