This paper proposes a class of asymmetric Autoregressive Conditional Duration models, which extends the ACD model of Engle and Russell (1997). The asymmetry consists of letting the duration process depend on the state of the price process in the beginning and at the end of each duration. If the...

This paper tests market co-integration, market leadership and price margins in the context of the recent development of European markets for imported off-season fresh fruit from countries in the southern hemisphere. The Engle-Granger and Johansen co-integration tests show that the main European...

In this paper we compare the incremental information content of lagged implied volatility to GARCH models of conditional volatility for a collection of agricultural commodities traded on the New York Board of Trade. We also assess the relevance of the additional information provided by the...

The Bond-Equity Yield Ratio (BEYR) has recently become a popular relative pricing tool favored by market practitioners. In this paper we compare the short-term profitability of a naive strategy based on the extreme values of the BEYR to the short-term profitability of a more sophisticated...

In this paper, we focus on the trade and quote data for the IBM stock traded at the NYSE.We present two different frameworks for analyzing this dataset. First, using regularly sampled observations, we characterize the intraday volatility of the mid-point of the bid-ask quotes by estimating GARCH...

Using a Markov switching model applied to the VIX and VDAX implied volatility indexes, we find that the volatility of the U.S. S&P100 index and German DAX index switched from a low-value state to a high-value state around the events of the Asian financial crisis. Moreover, the U.S. and German...

We put forward the Bond-Equity Yield Ratio (BEYR) as a criterium to dynamically allocate capital between equities and bonds on a short-term basis. Relying upon 30 years of monthly data for a large collection of countries, we use the cointegration, regimeswitching and ARMA-GARCH type...

We introduce a new empirical methodology that takes account of liquidity risk in a Value-at-Risk framework, and quantify liquidity risk premiums for portfolios and individual stocks traded on the automated auction market Xetra which operates at various European exchanges. When constructing...

Using density forecasts, we compare the predictive performance of duration models that have been developed for modelling intra-day data on stock markets. Our model portfolio encompasses the autoregressive conditional duration (ACD) model, its logarithmic version (Log-ACD), the threshold ACD...

We analyze whether the liquidity provision in a pure order book market during normal market conditions (low volatility regime) differs from what is observed when the market is under stress (high volatility regime). We show that the static relationship between liquidity and volatility is...
