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.

Rating Agency Actions and the Pricing of Debt and Equity of European Banks: What Can we Infer About Private Sector Monitoring of Bank Soundness?

Abstract
The recent consultative papers by the Basel Committee on Banking Supervision has raised the possibility of an explicit role for external rating agencies in the assessment of the credit risk of banks’ assets, including interbank claims. Any judgement on the merits of this proposal calls for an assessment of the information contained in credit ratings and its relationship to other publicly available information on the financial health of banks and borrowers. We assess this issue via an event study of rating change announcements by leading international rating agencies, focusing on rating changes for European banks for which data on bond and equity prices are available. We find little evidence of announcement effects on bond prices, which may reflect the lack of liquidity in bond markets in Europe during much of our sample period. For equity prices, we find strong effects of ratings changes, although some of our results may suffer from contamination by contemporaneous news events. We also test for pre-announcement and post-announcement effects, but find little evidence of either. Overall, our results suggest that ratings agencies may perform a useful role in summarizing and obtaining non-public information on banks and that monitoring of banks’ risk through bond holders appears to be relatively limited in Europe. The relatively weak monitoring by bondholders casts some doubt on the effectiveness of a subordinated debt requirement as a supervisory tool in the European context, at least until bond markets are more developed.

Environmental policy under product differentiation and asymmetric costs - Does leapfrogging occur and is it worth it?

IWH Discussion Papers,
No. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.

Make Work Pay – The effects of combination wage programs in the USA and in Great Britain

Abstract
Derzeit werden in Deutschland verschiedene Modelle zur reform des Steuer- und Transfersystems zur Subventionierung eines Niedriglohnsektors diskutiert. In anderen Ländern gibt es bereits seit mehreren jahren Konzepte zur finanziellen Besserstellung von beschäftigung gegenüber Arbeitslosigkeit. Zu den wohl bekanntesten programmen gehören der Earned Income Taxe Credit (EITC) in den USA sowie der Family Credit (FC) in Grossbritannien.Von besonderen Interesse sind die dort gewonnenen Erfahrungen über die Anreizwirkungen auf das Arbeitsangebot. Die Untersuchungen zeigen, daß für die Gruppe der bereits der bereits Erwerbstätigen eine Verringerung des Arbeitsvolumens folgt. Dieser negative Effekt kann jedoch überkompensiert werden durch positive Partizipationseffekte von bislang Nichterwerbstätigen. Eine Übertragung dieser programme auf Deutschland würde aufgrund einer vergleichsweise komprimierten Einkommensverteilung sowie eiem höherem Grundsicherungsniveau voraussichtlich zu einer stärkeren fiskalischen Belastung als in den USA oder Grossbritannien führen.

Revenue Implications of Trade Liberalization

Abstract
In recent decades many countries have dismantled trade barriers and opened their economies to international competition. Trade liberalization is seen to promote economic efficiency, international competitiveness, and an expansion of trade, perhaps especially in imperfectly competitive markets. Yet despite this progress in trade liberalization, as evidenced by the conclusion of the Uruguay Round in 1994 and the establishment of the World Trade Organization (WTO) in 1995, trade barriers are still widespread. Some economies and some sectors (e.g., agriculture in many industrial countries) remain relatively insulated from the global economy by a variety of nontariff and tariff barriers, even as import substitution continues to lose ground as a strategy for economic development.
