We argue that a transaction tax is likely to amplify, not dampen, volatility in the foreign exchange markets.Our argument stems from the decentralised trading practice and the presumable discrepancy between informed and uninformed traders valuations.Since informed traders valuations are likely...

This paper studies relationship lending in a framework where the cost of switching banks measures the degree of banking competition. The relationship lender's (insider bank's) informational advantage creates a lock-in effect, which is at its height when the switching cost is infinitesimal.This...

We study the adverse selection problem in imperfectly competitive credit markets and illustrate the circumstances where a separating equilibrium emerges, even without collateral.The borrowers are heterogeneous in their preferences concerning the banks.Separation obtains in market segments where...

Although beneficial allocational effects have been a central motivation for the Basel II capital adequacy reform, the interaction of these effects with Basel II's procyclical impact has been less discussed. In this paper, we investigate the effect of Basel II on the efficiency of bank lending....

Although beneficial allocational effects have been a central motivator for the Basel II capital adequacy reform, the interaction of these effects with Basel II's procyclical impact has been less discussed. In this paper, we investigate the effect of capital requirements on the allocation of...

We show how banks excessive risk-taking, stemming from informational asymmetries in loan markets, can lead to an excessive output loss when a recession starts. Risk-based capital requirements can alleviate the output loss by reducing excessive risk-taking in normal times. Model simulations...

In this paper, we propose a new noncausal vector autoregressive (VAR) model for non-Gaussian time series. The assumption of non-Gaussianity is needed for reasons of identifiability. Assuming that the error distribution belongs to a fairly general class of elliptical distributions, we develop an...

No consensus has emerged on how to deal with overnight returns when calculating realized volatility in markets where trading does not take place 24 hours a day. This paper explores several common volatility applications, investigating how the chosen treatment of overnight returns affects the...
