Estimating Monetary Policy Rules when the Zero Lower Bound on Nominal Interest Rates is Approached

Kiel Working Papers, No. 1898,

Abstract
Monetary policy rule parameters estimated with conventional estimation techniques can be severely biased if the estimation sample includes periods of low interest rates. Nominal interest rates cannot be negative, so that censored regression methods like Tobit estimation have to be used to achieve unbiased estimates. We use IV-Tobit regression to estimate monetary policy responses for Japan, the US and the Euro area. The estimation results show that the bias of conventional estimation methods is sizeable for the inflation response parameter, while it is very small for the output gap response and the interest rate smoothing parameter. We demonstrate how IV-Tobit estimation can be used to study how policy responses change when the zero lower bound is approached. Further, we show how one can use the IV-Tobit approach to distinguish between desired policy responses, that the central bank would implement if there was no zero lower bound, and the actual ones and provide estimates of both.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
Nr. 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.

Do We Need New Modelling Approaches in Macroeconomics?
Claudia M. Buch, Oliver Holtemöller
Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

On the Economics of Ex-Post Transfers in a Federal State: A Mechanism Design Approach
Martin Altemeyer-Bartscher, T. Kuhn
WWDP, 95,
Nr. 95,
2008
Abstract
As a common feature in many federal states grants-in aid are payed to jurisdictions ex post, i.e. after local policy measures have chosen. We show that the central government cannot offer grants ex ante in a federal states with informational asymmetries as well as inter-temporal commitment problems. Local governments’ incentives to provide public goods are distorted if they rely on federal grants-in-aid offered ex post. Furthermore it becomes obvious that local governments are apt to substitute tax revenue for higher grants-in-aid if relevant local data are unobservable for the central government. To which extend ex post transfers mitigate local governments’ incentives crucially depends on the information structure predominant in the federation.

Banks’ Internationalization Strategies: The Role of Bank Capital Regulation
Diemo Dietrich, Uwe Vollmer
IWH Discussion Papers,
Nr. 18,
2006
Abstract
This paper studies how capital requirements influence a bank’s mode of entry into foreign financial markets. We develop a model of an internationally operating bank that creates and allocates liquidity across countries and argue that the advantage of multinational banking over offering cross-border financial services depends on the benefit and the cost of intimacy with local markets. The benefit is that it allows to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a multinational bank relies to allocate liquidity across countries. Capital requirements affect this trade-off by influencing the degree of inefficiency in internal capital markets.

Currency Crisis Prediction Using ADR Market Data: An Options-based Approach
Stefan Eichler, Dominik Maltritz
International Journal of Forecasting,
Nr. 4,
2010
Abstract
During capital control episodes, large price deviations between American Depositary Receipts (ADR) and their underlying stocks signal that a currency crisis is about to occur. We interpret this price spread as the price of a call option. Using option pricing theory we derive detailed information about both the probability of a currency crisis and the expected magnitude of devaluation. Analyzing daily ADR market data preceding the Venezuelan crisis (1996), our approach predicts crisis probabilities of almost 100% and forecasts the exchange rate after floating quite accurately. During the Argentine crisis (2002), the estimated exchange rates are similar to the actual ones.

Abstract
Der Umgang mit den Schuldenkrisen in einigen Euroländern steht derzeit ganz oben auf der Tagesordnung der EWU-Gremien. Der Rettungsschirm zur aktuellen Krisenbewältigung ist allerdings bis 2013 befristet. Danach sollte ein dauerhafter Krisenpräventions- und Krisenmanagementmechanismus eingesetzt werden. Wie ein solcher Mechanismus zu gestalten ist, erläutern die Autoren in diesem Beitrag.

Humankapital in der Transformation - Das Beispiel der neuen Länder
Ralf Müller
IWH Discussion Papers,
Nr. 126,
2000
Abstract
Zwischen der Humankapitalausstattung und der Produktivität von Volkswirtschaften gibt es einen engen Zusammenhang. Folglich könnte für die Erklärung der Produktivi-tätslücke zwischen den alten und neuen Ländern neben anderen Faktoren auch Unter-schiede in der Ausstattung mit Humankapital eine Rolle spielen. Die Analyse zeigt je-doch, dass Humankapitalnachteile der neuen Länder nach 1990 weitgehend auf im Ar-beitsprozess gebildetes Wissen beschränkt waren, die im Zeitverlauf an Bedeutung ver-loren. Für im formalen Bildungssystem (Schulen, Universitäten) gebildetes Humankapi-tal bestand dagegen schon zu Beginn der Transformation ein hohes Niveau, das gegen-über den alten Ländern bis heute eher Vorteile aufweist. Letztlich erweist sich das Hu-mankapital für die neuen Länder eher als ein nachfrageseitiges denn als ein angebotssei-tiges Problem. Dies gründet auf der Branchen- und Unternehmensstruktur der neuen Länder, die im Vergleich zu den alten Ländern geringe Qualifikationsansprüche stellt.
