The minimum liquidity deficit and the maturity structure of central banks' open market operations: lessons from the financial crisis

This paper studies the relationship between the size of the banking sector’s refinancing needs vis-à-vis the central bank and auction rates in its open market operations in times of financial market stress. In a theoretical model, it is found that marginal rates at central bank auctions may increase if the share of troubled banks becomes too high relative to the total size of the banking sector’s refinancing needs. An empirical analysis then aims at determining the size of open market operations needed to absorb large stress levels in interbank money markets and hence contain central bank auction rates. Finally, the paper analyses effects of the composition of open market operations of different maturities on auction rates. It is found that a too high share of longer-term refinancing induces a rise in auction rates which is undesirable. Therefore, the analysis suggests that there is a lower bound for the amount of liquidity provided through short-term operations.

International trade, hedging and the demand for forward contracts

There is a huge literature on the effects of uncertainty on trade levels. One very strong result of that literature is that uncertainty should not matter, as long as well developed forward markets exist. The empirical implications of this result, however, are hard to find in the data. We model terms of trade uncertainty in a small open economy with uncertainty stemming from abroad and derive the equilibrium demand for forward contracts. It turns out that risk averse agents will not buy forwards at an actuarially fair price, thus rendering both the full-hedge theorem and the separation theorem of the aforementioned literature obsolete. Using real world data for Germany we calibrate our model. We find that in equilibrium risk averse agents will buy forward cover only for nvestment reasons. The amount of forwards purchased is around 20% of equilibrium imports. This is broadly in accordance with empirical observed ratios. --forward contracts,terms of trade uncertainty,hedging

International Trade, Hedging and the Demand for Forward Contracts

One of the main results of the literature on the effects of uncertainty on trade states that uncertainty should not matter in the presence of well developed forward markets. Empirical studies, however, do not support this result. We derive the demand for forward cover in a small open economy with terms of trade uncertainty. Adopting a standard and more realistic decision structure than the one usually used in this literature, we find that risk averse agents will not buy forwards at an unbiased price. Agents treat forward contracts as an asset rather than as an insurance. This is the reason why, when calibrating the model, only 17% of imports are covered by forwards. --

Bidding behaviour in the ECB’s main refinancing operations during the financial crisis

Liquidity provision through its repo auctions has been one of the main instruments of the European Central Bank (ECB) to address the recent tensions in financial markets since summer 2007. In this paper, we analyse banks’ bidding behaviour in the ECB’s main refinancing operations (MROs) during the ongoing turmoil in money and financial markets. We employ a unique data set comprising repo auctions from March 2004 to October 2008 with bidding data from 877 counterparties. We find that increased bid rates during the turmoil can be explained by, inter alia, the increased individual refinancing motive, the increased attractiveness of the ECB’s tender operations due to its collateral framework and banks’ bidding more aggressively, i.e. at higher rates to avoid being rationed at the marginal rate in times of increased liquidity uncertainty.

Capital Flows and Trade in an Integrated World

The world we live in is increasingly integrated. For the work of economists, increasing international integration bears a significant importance. The present thesis is essentially a work on International Economics. As such it is no exception in that it consists of different chapters, all of which address different issues in the field. The first two chapters are theoretical in nature, whereas the third is empirical. The last chapter provides a technical reference to mathematical problems encountered in the first chapter. The first chapter is concerned with one of the negative effect of international trade: terms-of-trade uncertainty. It asks (and answers) the question why economic agents in practice fail to (completely) hedge away foreign price uncertainty in the presence of well-developed forward markets, even though theoretically they should obtain a full-hedge. The second chapter explores some of the effects international capital flows bring to a country that opens up its capital account. The third chapter describes the evolution of international capital flows and trade flows over that last decade. The last chapter is concerned with the existence of explicit demand schedules under expected utility maximization when the random variable is nonlinearly transformed.Die Welt in der wir leben ist durch zunehmende Integration in fast allen Bereichen des Lebens gekennzeichnet. In der ökonomischen Sphäre wird diese zunehmende Integration auch oft mit dem Begriff Globalisierung beschrieben. Zwei Hauptmerkmale der Globalisierung sind dabei zunehmende internationale Kapital- und Handelsströme. Die vorliegende Dissertation beschäftigt sich mit ausgesuchten Teilaspekten dieser Phänomene. "Warum sichern sich die Wirtschaftssubjekte in der Praxis nur unvollständig gegenüber Wechselkursrisiken ab, obwohl sie theoretisch eine vollständige Absicherung wählen sollten?", "Welchen Einfluß hat die Herkunft von Kapital auf die Ökonomie?" sowie "Wie ist der empirische Befund zur Entwicklung von Handels- und Kapitalströmen in der letzten Dekade?" sind Fragen denen die vorliegende Arbeit nachgeht. Ein Kapitel mit Ergebnissen zur Existenz von expliziten Nachfragefunktionen unter Erwartungsnutzenmaximierung bei zugrundeliegender nichtlinearer Transformation der Zufallsvariablen (eine Fragestellung die im Rahmen der Bearbeitung von Kapitel 1 auftaucht) beschliesst die Arbeit
