In recent years the Value at Risk (VaR) concept for measuring downside risk has been widely studied. VaR basically is a summary statistic that quantifies the exposure of an asset or portfolio to market risk, or the risk that a position declines in value with adverse market price changes. Three...

In fixed income analysis, duration plays a central role as a proxy for interest rate risk exposure. Although this role relies on the interpretation of duration as (minus) the yield elasticity of the bond price, duration is measured as a bond's present value weighted average time to maturity and...

An intensive and still growing body of research focuses on estimating a portfolio’s Value-at-Risk. Depending on both the degree of non-linearity of the instruments comprised in the portfolio and the willingness to make restrictive assumptions on the underlying statistical distributions, a...

Most of the available monthly interest data series consist of monthly averages of daily observations. It is well- known that this averaging introduces spurious autocorrelation effects in the first differences of the series. It is exactly this differenced series we are interested in when...

We develop a new likelihood-based approach to sign trades in the absence of quotes. It is equally efficient as existing MCMC methods, but more than 10 times faster. It can deal with the occurrence of multiple trades at the same time, and noisily observed trade times. We apply this method to a...

In this paper we introduce a new methodology to price American put options under stochastic interest

Market integration is studied for Dutch stocks cross-listed at the NYSE. Trading starts in Amsterdam and ends in New York with a one-hour overlap. Both markets are not perfectly integrated in that they can be viewed as one market with the well-documented U-shape in volatility, volume and spread....

A number of recent theoretical studies have explored trading in fragmented markets, e.g. Biais et al. (2000), a phenomenon increasingly witnessed in modern markets. The key assumption generating the results is that there is at least one liquidity demander exploiting access to all markets by...

Signed customer order flow correlates with permanent price changes in equity and nonequity markets. We exploit macro news events in the 30Y treasury futures market to identify causality from customer flow to riskfree rates. We remove the positive feedback trading part and establish that, in the...

U.S. trading in non-U.S. stocks has grown dramatically. Round-the-clock, these stocks trade in the home market, in the U.S. market and, potentially, in both markets simultaneously. We use a state space model to study 24-hour price discovery. As opposed to the standard "variance ratio'' approach,...
