This paper is concerned with the stategic use of a private information on the stock market. A repeated auction model is used to analyze the evolution of the price system on a market with asymmetric information. The model turns out to be a zero-sum repeated game with one-sided information, as...

As one important form of market circuit breakers, price limits have been often imposed in stock and futures markets. This paper considers modeling the return process of such assets, focusing on the treatment of price limits. As a result, a censored-GARCH model is formulated and a Bayesian...

As one important form of market circuit breakers, price limits have been often imposed in stock and future mnarkets. This paper considers modelling the return process of such assets, focusing on the treatment of price limits. As a result, a censored-GARCH model is formulated and a Bayesian...

The paper proposes an original class of conditionally heteroskedastic models aimed to capture a new concept of asymmetry. Not only past up and down moves of stock market returns have different impacts on the conditional variance, but also, positive and negative changes are governed by different...

We provide a definition of the rational expectations core in an atomless economy with asset markets and show that allocations in the core can be decentralized by a system of asset and spot prices as rational expectations equilibria.

The objective of this paper is to identify the determinants of office capitalization rates for a panel of 52 countries (developed and emerging countries) between 2000 and 2006. Our assumption, based on a Capital Asset Pricing Model, is that the capitalization rate should be at least proportional...

In this paper we model Value-at-Risk (VaR) for daily stock index returns using a collection of parametric models of the ARCH family based on the skewed Student distribution. We show that models that rely on a symmetric density distribution for the error term underperform with respect to skewed...
