A theoretical model is presented, which predicts a heightening in return volatility following a news reversal. A reversal occurs when a value of an economic indicator that is larger than the forecasted value is followed in the following month by a value smaller than the forecasted value, or vice...

We decompose US Treasury bid-ask spreads into inventory, adverse selection and order processing costs by using the fact that inventory trades have different effects on spreads than do proprietary trades. We exploit this asymmetry and develop a technique to identify the three components of the...

This paper tests for and provides evidence of nonlinear dependencies in palladium and platinum futures prices. The results indicate that ARCH-type processes, with controls for seasonality and contract-maturity effects, generally explain the nonlinearities in the data. We also present evidence...

This article investigates the impact of margin requirements on the trading activity and volatility in futures markets. We extend Hartzmark's (1986) model for futures demand to allow for the costs imposed by margins to change across the maturity of the contract. The model is tested employing data...

Research in economics and finance documents a puzzling negative relationship between stock returns and inflation rates in markets of industrialized economies. The present study investigates this relationship for Korea and Mexico. We show that the negative relationship between the real stock...

We conduct tests for the presence of low-dimensional chaotic structure in the futures prices of four important agricultural commodities. Though there is strong evidence of non-linear dependence, the evidence suggests that there is no long-lasting chaotic structure. The dimension estimates for...
